00:00 right here. I'm sorry. down Right and as well here.
00:06 just want And I also for this track up here. I had,
00:11 , kind of after this truncation I kind of pinched it out.
00:15 then when I was going through and it, I was like,
00:18 I think actually that high, because of this top lap,
00:22 comes all the way down. Uh , how can I I should be
00:48 the request to point at your Right. Oh, I mean,
00:52 gotten on this other screen if you to try that again. Yeah.
00:58 remote control. There is. So requesting. Okay. There,
01:05 Okay. Can you see my point ? Yeah. Yeah, that's
01:09 Yeah. Okay, so, one of the problems you have is
01:15 you see, have on lap, basically shifted on lap. Right.
01:20 So you see, I have that . Oh, stand that. Not
01:24 same geometry. Yeah. Yeah, you've got the mouse over right
01:29 Where? That you're correct. That about that? That's a low
01:33 Correct? These the same, I mean, once you've done
01:36 then the other should repeat, Yeah. Green's pretty good.
01:41 I think you could just extend that there. Then that becomes a low
01:45 . That's a low stand there. then this is troubling, because that's
01:50 this unit here is the same as one. There s E.
01:58 Yeah. So can you repeat what just said about them being the
02:03 Yeah. This jobs you're here is same as that geography there.
02:07 I'm not seeing your mouth. Can you do that again? Is
02:10 request here? Oh, there you . Sorry. Maybe I moved it
02:13 something like that. Yeah. You controlling Joseph. Screen says I'm
02:18 Yeah. Can you move? Can see my point here? Are you
02:23 it? Yeah. Um, is one is not on the screen is
02:26 moving. Yeah, it's just lagging , I think. Oh,
02:32 Yeah, I got the screen reset so I can edit it.
02:40 . Uh, you wanna undo what just did? I think I just
02:45 . Yeah. OK, um, is PowerPoint, right? Yes.
02:51 , yeah. So can you put into a PowerPoint mode? Actually,
02:56 , don't Father, let me, Uh, yeah, that's the
03:10 I've been that one and then the to the right of it. The
03:12 I've been using. Let me uh do you have drawn on here
03:19 the nice pens? See? So is like power point from 2011.
03:23 is like my super old Mac book . Oh, yeah. Okay,
03:36 that unit there Yeah. Okay. me just, uh there's no
03:44 so you can see we'll just put red box, right? Yeah.
03:49 there is basically the same as you know? Exactly. E your
03:54 boundary goes underneath that wedge. The is you know, this sequence boundary
04:01 much more aggressive. Bond, you this basement floor fan on this on
04:05 sort of much more. Just a stand. Yeah, all the sea
04:09 here, But it's not enough to this low stand wedge out past the
04:13 one. So it's confusing. You . You sort of have a shelf
04:17 , low stand wedge over a kind basic floor low stand wedge,
04:23 Superimposing too low stand wedges, I think that's why you got
04:28 Like why you didn't want to call a low stand, right?
04:33 And so the blank one, but blank one that shows that on lap
04:38 on on the effort be at the one where that geometry, like it
04:42 the same. It's the same type bass and sand wedge, right?
04:47 , way down there. Right? . On this is your programming shelf
04:53 Wedge builds out over the fam right . Eventually, sea level rises above
05:00 . You flat flood back and get back step in Paris sequences. You
05:03 don't have that in that last okay? Yeah. No.
05:09 Thank you. I just I was of like, how did the asked
05:12 do the, um, do the ? Because I had thought I had
05:17 figured out, drawing out the and I started labeling stuff, and
05:19 was like, Oh, actually, think that's wrong. And then I
05:22 coloring stuff in, and then I , you know, you know,
05:26 not doing too bad. Just a of things that, you know,
05:29 make sure that your market on lap lot of good stuff Don't Don't leave
05:32 that out, okay? Okay. good. Thank you. Okay.
05:40 mind? You bet. Yeah, lot. Uh, Okay.
05:44 Yeah. Go ahead, Don. , Sarah. Okay. And I'm
05:50 to see you. Who else is so far? We just reviewing the
05:55 kind of while we're getting started Wow, That looks nice, isn't
06:01 ? Thank you. Yeah. You the same thing here, right?
06:08 see, there's a surface there. . I need to do the same
06:12 . Um ah. Requests. Remote . I think I just improve
06:23 Okay, now you can see now got a nice white arrow there s
06:28 that you've got your incised valley, then you put you see concerned below
06:32 low stand wedge. Correct? That's exactly same geometry you have
06:39 So there's your sequence. Boundary. don't see your mouth moving your
06:43 Okay. Um, what program you ? Thanks. Cape. Okay.
06:51 never used that before, but, , scroll down a little bit with
06:58 mouths. I think you might be my second screen. I've got a
07:03 circular. You see that now? , but wait. I see
07:10 Yeah, that black. That surface drawn there. Um, which number
07:18 are you talking about, Uh, all over the place. Um,
07:23 how I labeled. Like what? Yeah. Uh, yeah. I
07:44 wanna let me draw. Yeah, can see my point now.
07:50 uh, so, you know, your incised valley. Correct.
07:54 now I don't see. I thought it must be my point rooms.
07:58 see it there? Yeah, it's out. Um, okay, I've
08:04 control, but I'm having a hard . There you go. I see
08:12 now. So here, go over the see the black pointer in the
08:18 left corner of the screen. Click set out. Now it will be
08:22 select tool instead of a drawing So that so There's your inspires valley
08:28 . Correct. And that's your secrets that you've drawn extending away from
08:33 Okay, so what's above the Boundary a PST? No. What's
08:42 the sequence? Boundary. There's your . Boundary here. All right.
08:53 the low stance. This low Yeah. The low stance systems
08:56 Right. So there's your incised That's your relative conformity. That's still
09:00 sequence boundary. I don't to your moving again. I don't know what's
09:05 on. So I'm like, I'm . I don't even get the right
09:11 . I think that's why I'm So I apologize. I think it
09:14 be on my end, but I know. Are you guys able to
09:18 his culture, You know, on when he has the out? Until
09:24 huh, That's moving now. yeah? What was that? You
09:39 screenshot it and then pull it up your computer. Yeah, I could
09:43 that. Yeah. We, uh , uh, like the other
10:14 Yes. Were you trying to draw it? Yeah. So if you
10:26 to view options in Zoom, there's feature called Candidate. What's up?
10:33 , up at the top, you options, and then you click
10:37 and I think it will let you on it. Oh, there we
10:43 . Yeah. So there's your incised . Correct? Yeah. And that
10:52 down there. Right there is your your shoreline right there. Right
10:58 Is your shoreline up here? That's basic shifting shoreline, right? So
11:03 , Linus. Seaward of that That's a drop of base level.
11:08 , right. There's your There's your stand. There's your wedge That's low
11:13 . That's not aggressive because, you , you got a clown a form
11:17 . You have a basin with shipping form producing this this wedge of
11:21 Right? So that blue section is wedge. That's the low stand
11:29 Yeah. Yeah, he did it . Up here. This is exactly
11:33 geometry. So the only I don't is that you interpreted correctly there.
11:37 is exhausting job. There's no right? I see. I see
11:42 what you're trying to. Yeah, That should cut off there. You
11:49 not gonna pick but one of the students, the same thing. And
11:52 corrected that version. Uh, so you know, it was that was
11:56 only mistaking me. Otherwise, it real good. You know,
12:00 and baseball fans, you know, is some laptop going on here,
12:07 there that you've missed. Yeah, very minor things. But, you
12:16 , and, uh, you just make sure, like here that
12:19 lap out right there. You see ? All right, so don't don't
12:23 any on laps, right? Don't here. I know it's a
12:27 The ass, You know, make you sort of mark ma'lik here.
12:32 at least one narrow. So that top lap there that's on Latin
12:39 right? Yeah. Yeah, there's lapse. So that that's your basically
12:42 on that right there from this unit that unit there. Right Anyway,
12:48 than that looks pretty good. I you've got You've got most of
12:51 right? You know, you've got trunk cases in here. You might
12:54 label right top lap truncation right in was there, right? So sometimes
13:00 label them Sometimes you don't just make you get it all in there.
13:04 there's there's there's truncation right there. , I wasn't sure if you wanted
13:08 to label. All of them are there was, like, most like
13:11 , you know, to be honest as long as I think you got
13:15 gist of it. You know most them that words, but it does
13:18 label the Marcus. If you miss , you may miss a surface or
13:22 traffic, right. So e will on everything rather than skipping anything.
13:28 go through a few more in there fix that one. Now just I
13:40 Maria's on there. She's a co . So, Murray, can you
13:43 track of once? I think everyone's . But if students trying to get
13:47 make sure that you let them in fun talking? Okay, e figure
13:56 Oh, okay. So apologies. that those that came in late We've
14:03 been reviewing some of the some of excess some of the, uh,
14:08 on assignment to and, uh, everyone's got the right track, You
14:12 , all of you getting most of . Some of you have all of
14:15 and one or two of you are just missing a couple of minor
14:20 So nothing super super critical there. , any other questions, or does
14:28 want toe view that some more? , Daniel. Yeah. Everybody
14:37 It should be, uh, everybody be able thio share. Mhm.
15:12 . Mhm. Okay. Yeah, . Oh, yeah. So the
15:49 hours of your top lab correct. . Okay, So where's your
16:04 You're already clearly showing that Mhm. , they are correct. Yeah.
16:15 sometimes the sides of the channel roads the sides and underneath eso those top
16:21 there all top lap truncation to use term. Yeah. Okay. I
16:40 what I'll do is, uh um me just, uh give me one
16:54 . Here, bear with me. huh. Okay. Can you all
17:27 that? Okay, So, yeah. So, in general,
17:59 know that the break is this this here, right? You're all going
18:04 kind of circle that. Okay. know, it's there. There,
18:13 , there that it was truncated. , you know, you could sort
18:16 guess that the directory of that is P a right. Sorry,
18:22 Yeah. You know, and then goes essentially horizontal. Then you can
18:27 just there. There's a little bit it downshifts to there. That's so
18:32 degradation. Then it's then it's p to a Okay. Same thing
18:38 You could you could just sort of along and it drops. Then it
18:43 back up again. Okay. And here's the back. Stepping from there
18:48 there. That's your are, then you're back to your AP the p
18:57 that if you track that if you that roll over, you'll you'll see
19:03 same pattern every time. Okay, it is. There. It's d
19:08 , then it's back toe AP Full image because I was actually because
19:13 they said, Look for, low stand deported finishes I was actually
19:17 trouble with that because I couldn't actually it. So I think I cannot
19:21 it now. It's like a 100 . Exactly those things down there.
19:25 a those the suffering fan politics, ? Yeah, so these low stands
19:31 have them. But these low stands so 22 varieties of low standing in
19:36 that a little bit confused. About ? Yeah. Other questions. E
19:46 a question about the incised Valley. ? Yes, radio. So eyes
19:53 part of the is that part of low sand? But this exercise,
19:58 going to consider that part of the staff correct. However you know there
20:03 there, and we will talk about next week when we get into,
20:07 , next week when we talk about sequence photography. So a lot of
20:12 notice the valleys filled with transgressive John Brian Wagner explicitly said Anything that's
20:19 the Valley, by definition, is stand. Because of its physical
20:23 There's a lot of sentiment ologists Wait minute. If you have a transgressive
20:27 filled, why isn't that transgressive systems ? So there's There is significant debate
20:32 the community asses. Whether transgressive Valley part of the transgressive systems, tracked
20:38 part of the low stance on E it all and see the transgressive Valley
20:44 . So it's probably one that won argument, uh, with purpose of
20:49 pure geometry. We'll call that we're We're just call the Valley Fields Low
20:54 , correct. Depending on how the is filled, there could be a
20:59 of transgressive from the values. Think why people have sort of people don't
21:04 the transgressive systems track, because it be very confusing. So that's a
21:09 question. And there's not a simple my non simple answer. Answer your
21:14 . Yeah, just a color coded different than all the systems tractors.
21:22 wasn't sure that's not both ways a long to say that if it you're
21:28 it has as a distinct feature you , on you could say, If
21:34 want to be clever, you Valley fills. Maybe, you
21:37 Valley Valley erosion surfaces sort of cut falling stage and low sound, but
21:43 can be filled during during the transgressive that Z Like I said, it's
21:47 there's no simple answer to that question . You know, if you have
21:55 Valley overline Shore Face, it's still , um, or proximate faces over
22:00 distant face. You know you We're gonna come back to that and
22:05 it in detail. So that's not question that we're going to resolve
22:09 We'll have, uh, a lot lectures on non marine secret photography
22:15 you know, on one of the . One of the things too remember
22:18 you know, the reason why we with processed geography in the first assignment
22:24 you know, hopefully all of more or less, given a suite
22:29 assumptions about settlements, supply base that change will come up with similar looking
22:35 section of geometries. That means you understand how the static graphic is
22:40 Okay, now, whether or not want to call a transgressive value field
22:45 low stand whether or not you want call Fallen stage late, high standard
22:49 stage. You know, it's sort an argument about terminology as long as
22:54 understand how things correlate, how things . Long as you understand the process
22:58 builds photography, you can call the whatever you want it. Right
23:03 you know, you have to use that I'll be happy with quiz,
23:07 know, But But by and um, you know, uh,
23:16 large there is There is a lot interpretation involved, And will way sort
23:21 get into that way, get into course. Any other questions about the
23:31 ? Anyway, thank you for advising about how to energy. I learned
23:36 about zoom every day. Um, was very kind to tell me that
23:42 thought I was an experienced June But as you're discovering, even I'm
23:46 perfect. Right versus all of our professors with their radio, I'll be
23:53 better after this. You got a competition. So now. So the
23:58 question I wanna ask you is do have the information about the quiz
24:02 Get those emails. Okay. So place is gonna go live at,
24:09 at what time did I say? , 8:20 a.m. So, 10 minutes
24:15 class time on it will shut down think I said in 9 35 you'll
24:20 exactly 30 minutes to do the quiz will automatically shut you off.
24:25 course I wrote the quiz. I've at least a dozen times to make
24:29 that it's working. I could do in about two minutes, but then
24:33 , I know the answer. you know, uh, I read
24:36 that if it takes Professor 10 minutes do it, it should take the
24:39 three times longer, so you should plenty of time to do it.
24:44 gonna have. I believe it. 10. Multiple choice questions,
24:51 that address various aspects of what we about last week. I don't think
24:57 gonna tell you anything new today on exam, but I will. I
25:02 reinforce things that will be on the . But won't there'll be nothing I
25:06 today? That's new that you've never before. Eso the questions will deal
25:12 things like lack of concepts a little about the definitions of sequences. And
25:16 about history of sequence photography? Some those base level concepts, you
25:21 a combination accumulation. So you should should make sure that you are familiar
25:26 those terms. I'm hoping, you , having gone to enough of the
25:30 that you will be, you'll be those those concepts. Yes. And
25:36 , for some reason, I didn't the communication regarding because not true.
25:41 ? Oh, uh, now you're blackboard, right? Yes. So
25:47 did. Everyone get the email? , you see? Oh,
26:01 so if you all have a pen pencil, you need a password to
26:05 into the quiz. Password is 63 30 The last of its type That
26:13 3 86 380 So the course number ? Yeah. Um, when When
26:23 do the, uh When you if do question to require to type
26:28 um, I do want to Okay, having said that because I
26:33 I have a short answer question So we're gonna have It's a multiple
26:37 . Then I've got some diagrams we to answer some questions about, you
26:41 , shoreline trajectory on that patterns, what we've been doing the past,
26:46 , you know, reinforcing what we've doing in the assignments. And then
26:50 one short answer. Questions were required write. Move your sentence too,
26:55 because there's a short answer. will not give you an automatic
26:59 I will have to create that person taking long to do. I probably
27:05 have it done until we meet next . But at least you know e
27:09 , the craziest part of the But it's as much a Z much
27:13 give me a feel for how much it picking up versus, uh,
27:17 know, if you're having any certainly all the You know, I
27:20 by now I've interacted, but I pretty well all of you either sent
27:24 a rough copy of something you're working . And you've had some discussion not
27:28 anyone making, you know, grievous . E think I told you last
27:33 way back, I had a student interpreted the lap out diagram upside down
27:38 like, That's a pretty bad right? So I felt e just
27:43 doing again. E don't know what starts, right? So the assignments
27:49 going to get a little bit harder we get data is always harder than
27:53 I call these sort of fake at thes air designed to not have any
27:58 noise in there. So messing this with data. So it is important
28:03 get the theoretical Assam is correct you know, if if you get
28:10 that's sort of supposed to be fairly obvious, incorrect, you'll have
28:14 hard time with real data, which which is messed ready, already struggling
28:19 getting the about on the size of . It's not hard you do your
28:25 and the annual you, uh, . Okay, once again, what
28:29 do some reviews of seismic of the interpretation. And I don't think that
28:34 will next week, is that Yeah. So I will tell you
28:40 always get criticized a little bit in force for being a fuzzy on
28:45 There's a couple of reasons why this . To be honest with, you
28:50 , professors, people tend to treat like they were treatment and, you
28:55 , I'm a pretty smart guy, I was always a bit last
28:57 Not great deadlines, You know, always, you know, not always
29:02 extensions, but usually people you they gave you the benefit of the
29:05 . So I tend to, you , as flexible as is reasonable.
29:09 basic philosophy is one time handed grades . I will no longer accept an
29:15 . Somebody's really struggling in their I know it's not fair to those
29:19 you that do the work on To be honest, I've never found
29:22 . You know, if a student until until the last minute to do
29:26 , a lot of problems result. know, you may need the rights
29:30 me that, you know, I'm too busy to be able to give
29:33 to you with the last minute. you know my approach to solving
29:38 I am definitely a last minute guy again. This is this is personal
29:42 for your lives. But if I'm with the task, typically, what
29:47 do is I do a little bit work early on, maybe 15 minutes
29:51 an hour just to get approval for difficult this task is gonna be on
29:56 I feel I'm making progress right I'm like, Okay, uh,
30:00 know, it's not gonna take forever do that. I can leave it
30:03 the last minute where sometimes I'll start task. And I'm like,
30:07 my goodness, this is gonna be nightmare on, you know? So
30:11 sort of just part time management you know, it's getting a feel
30:15 how long it's gonna take Thio any job, you know, whatever that
30:20 be, you know? And, know, uh, we, um
30:26 don't recall if we did, a little interviews last night, so
30:32 let's just do a little a little here on you could just hit your
30:41 reactions with just So just give me thumbs up if you have a job
30:47 a geology related food Right now, don't understand how many of you are
30:56 . Okay, So that Z What if you were dok,
31:02 you know, so as you a za working stiff as we like
31:06 call you, you know, you already you're managing time your management time
31:12 work, perhaps your family, perhaps the course. For those of you
31:16 aren't working, maybe you have more to vote on the course.
31:18 you know, life is all about management. I'm lucky I'm extremely fast
31:24 . I write extremely fast I get done quickly. I don't necessarily work
31:30 hours, but when I work, completely focused. You cannot distract
31:35 you know? So when I when work on something, I get it
31:38 right. Don't get distracted on. seen people who work for five
31:42 and then we're off getting coffee, to their neighbor. You know,
31:46 all have, You know, you , you all know in your hearts
31:49 you work, you know? So with this course, you know,
31:53 more complicated the exercises are, just a little bit of time looking at
31:57 early. You know, maybe just a little bit of work on
32:00 Just enough to say Okay, Do have a feeling For what? The
32:02 is? That way to say, , shoot. I probably need to
32:06 that. Talked about a chariot Some . You know, the worst thing
32:10 could do is live last minute then email me and say,
32:13 it's due in five minutes. Can talk to me right now? Like
32:16 . But you know, if there's serious problems, it's gonna be hard
32:20 give you advice that you need to sure that you're successful. So any
32:26 the other questions about assignments before we of get into. And I think
32:32 . I'm memory. You know, you have to do is is that
32:36 understanding? I haven't. I've gone black more than taking a quiz,
32:40 know, on right now, if got as a student with quiz won't
32:44 up, I think it will become at 8:20 a.m. Tomorrow, Uh,
32:49 time. So, you know, up. Uh, turn your computer
32:53 . Log into blackboard at 8. . Questions show. You've only got
32:58 minutes to do it. ASL longs started with 45 after nine. You'll
33:03 a full half an hour. If wake up in 20 then you're already
33:07 have 10 minutes to do it, exam's gonna shut down at 9.
33:11 . Then after that, you take 10 minute break, and then,
33:15 , I'll start the zoom up to 9. 35 then you guys
33:18 uh you know, we'll probably start around 45 on. Uh, you
33:24 , I'll be happy to talk about at that time. If you have
33:27 . You know, if you're I wonder what the answer that
33:29 You know, I know you're I'll dying to know if you have problems
33:34 , uh, nobody has ever flunked of my quizzes on. Usually the
33:39 in this class range from a Right. So that z the only
33:44 I've had students that really did get it with students dropped out or every
33:51 in a while, the student is really struggling. I don't get the
33:54 that we have anybody in that in category in this class right way are
34:01 small class. And so we could lots of good discussion, right?
34:05 doke. Uh, what now uh, any any other questions?
34:16 . So what we gonna do now , uh, share my screen and
34:22 will get started on the presentation. what I want to talk about Thats
34:32 . You have a couple of things get through on the first lecture is
34:36 finish off. Sort of basic introduction sequence photography on. You've now seen
34:43 so called slug diagram several times Of course. You know, every
34:48 I show you with this. You be nodding with comfort because, you
34:52 , many of you just showed me laptop diagrams. And when you cover
34:56 all up in the things to look this diagram, right, So So
34:59 trying to get you to create this twice, right? You do it
35:04 with the accommodation exercises on when I you a diagram and you have the
35:09 out of colors. You didn't ask to do all that diagram, which
35:13 really should is drawing, you the shelf slope and drawing faces.
35:20 , uh, but actually a good for you. Maybe next time I'll
35:23 you to do that. Then you'll a You know, not only you
35:26 the systems trapped, you'll have. have the colored faces as well.
35:31 question is, what are the You what? What is the sequence?
35:36 Ultimately in the slaw sequences, they're , uh, conform packages of
35:43 All the layers in this white unit parallel to each other on their all
35:48 the same way. So they have experienced the same tectonic strata. Graphic
35:53 . Then this big anger on conformity separates another forwarded unit from the underlying
35:59 internally, within the black unit. , the layers are all conforming to
36:02 other, and they're like, So they make two sequences of
36:07 relatively informal layers with an anger of separating white sequence from the black
36:14 Okay, on, uh, the between a slaw sequences that the SLA
36:21 separate units that are separated by tectonic , which are usually expressed by angular
36:28 conformity. These on the Exon sequences separated by dis conformity, erosion
36:36 uh, that do not have any for defamation or anger or deformities.
36:42 the idea is that these Diskant for are produced by based on the drops
36:47 any tectonic processes required. Of these irrational surfaces. It's not that
36:53 not, Uh uh, that they're easy to see, but they can
36:59 more subtle than the obvious anger How are the important thing about these
37:04 these excellent type de positional sequences? they put sandstone out in the middle
37:10 the basis or in the center of so they drag the reservoir faces out
37:15 the basin, providing more distal exploration ? That was the reason why Exxon
37:21 interested in predicting these things because they to know, you know, particularly
37:26 the offshore bases, that they're exploring there were any reservoir. Sandstone is
37:31 there in the days that they were for conventional reservoirs and as well,
37:37 may get content sections even within these stands that have social potential. E
37:43 want to try to bring seeking strategic back Thio Petroleum Systems e You all
37:50 had petroleum system class, but it's to understand, uh, petroleum geology
37:57 went on teaches that class. You , hopefully you'll be able to fit
38:01 secret strata graphic knowledge into a better of petroleum systems. Now, once
38:08 , one of the problems in geology that there are, you know,
38:12 are rules, but there are lots off different sets of rules for different
38:19 of scientists. You know, when do engineering, you know this typically
38:24 one equation, you know. Then having 10 different equations to perform the
38:30 function. You know, you describe how a ball rolls down the
38:35 You don't you don't have five different to describe that you want one equation
38:40 geologists do much more complicated problems that necessarily reducible to simple equations. As
38:48 consequence, we have different terminologies ways attack Howie Action. How we actually
38:56 rocks So some of us start off mythology at faces or little faces.
39:07 you know this. This could be heard the term flu Viel faces deepwater
39:11 . Delta faces reef faces. A may be linked to her faces
39:21 So a channel about our channel faces . Sharp based, fine upward,
39:29 across their faces and Rick laminated faces abandoned channel fill faces. So three
39:36 can Make Babies Association and in that finding faces association that a Janet Phil
39:44 form a flu deposition system, which of channel about floodplains. Depending on
39:49 those informing during a period of following rising sea level, they may be
39:54 of a falling stage or low standard systems from are not ultimately those building
40:00 sequences. So I was trained in I call the European Texas school faces
40:07 associations, depth systems is like to in Texas on then the newer
40:13 tracks and sequences that sort of came , uh, sort of from from
40:19 now at the same time, John Van Wagner at Exxon was working
40:26 a guy named Chuck Campbell, and was very focused on on surfaces.
40:31 said, Well, you know, and face to face associations were very
40:36 , you know, you know, out of faces. Might consider consists
40:40 beds of, you know, little turban, tights and approach out of
40:44 , a little storm bed and another . So so faces May may consist
40:51 laminated bets on the lam in a of laminates sets, and they make
40:56 and bed sets. They built these called Paris sequences. The group of
41:00 Paris even sets on. Then they sequences. So here we have a
41:04 separate terminology for building the strata graphic from the thinnest laminar to thicker beds
41:13 bed sets and Paris sequences. of course, ultimately you get two
41:18 . So these parallel but rather different off subdividing strategic graffiti says there's lots
41:26 reasons why this is difficult to do it's painstaking. If you go into
41:31 field that we've got half a day measure 100 m off section cliff.
41:38 can't measure every laminate. It'll take forever. I know because I've done
41:43 . Eso commonly you love together. know, if you have, you
41:47 , 10 ft of Internet and sand and mud stones, you say unit
41:51 10 ft. Enrichment of mud, and sand stones. You don't
41:55 Layer one layer to layer three layer layer five layer six and three hours
42:03 , Later, 78. Later. you won't. You'll never, ever
42:07 anything done. So you know, use the face, use faces and
42:12 associations when we don't have much And And if we're concerned about extremely
42:18 reservoir details way may want to break geology into its individual events and laminar
42:24 in that sense. Now the other thing is that is that faces and
42:31 association. One of the questions okay, thes air, all walk
42:35 , faces, faces, associations, know, at least don't necessarily require
42:41 to bound them. You know, association might be separated by Shiism.
42:46 . We talked about last class, units all all generated by laminar or
42:53 surfaces of one kind or another. this if you will, is a
42:57 based description process. This is kind a combination off mythology and surfaces.
43:06 ? And you'll remember last week when when we, uh um last week
43:16 we went back. Thio do? week, when we introduced this
43:26 you could tell I'm struggling here, that's because I'm trying to This is
43:33 little scary here, but yeah, last week just to remind you I
43:45 that secrets photography is the integration off , which, if you will,
43:50 faces surfaces. Not every surface is . So, you know, the
43:56 school believes that every laminate and everybody important. But not every lap is
44:01 important sequence. Strata graphic surface. course, we're always trying to interpret
44:06 time strata graphic relationships. So it useful. Just sort of keeping that
44:13 mind. Okay. Yeah. So in the early seismic photography,
44:30 is a 1977 version. You there was there was one surface that
44:36 separated a package that was dominant, on lapping the land surface in a
44:43 position from a seismic unit that was on lapping slope that represented a major
44:51 which shifted on lap on that separated a low stand from a high stand
45:00 . Okay, so that was the and low staff. And then later
45:04 recognize that there was a surface within high stand that separated back, stepping
45:09 four stepping or retro traditional from pro units. And that, of
45:16 and the maximum funding surface that separated transgressive from the high stand systems trapped
45:22 the retro gradation ALS from the organizational accommodation, succession off Neil and
45:32 Yeah, so the next year and want to talk about is this thing
45:37 inside these accommodations, successions or systems that's thes thes things called Paris
45:45 Now the word para is used in to mean almost, but not quite
45:52 paradise. Something that it's sort of nice but not quite parent or talk
45:58 this is like, Well, it's of our talk to this, but
46:00 quite right. Eso that that word is used a lot in geology,
46:09 so a Paris sequence was primarily describing relatively shallow marine coastal faces.
46:18 on the classic Paris equals consists of upper coursing, faces succession in this
46:24 it goes from offshore are inter bended mud stones, thio, inter bedded
46:29 this case, how monkeys sand stones bed with mud stones, then into
46:34 a trough. Cross stratified short face . A little angle, stratified
46:41 Beach deposit, for sure, is the same as the beach. And
46:45 there's a razor sharp contact that superimposes offshore mud stones directly over shallow foreshore
46:55 . Okay, now this faces eyes conforming to growth is law.
47:01 all recalled office law, some of and Ali, which is good and
47:08 if you went through this. But Wolff's law, it says that you
47:12 only superimposed environments of deposition in the lay side by side. So in
47:18 view, the foreshore is Lambert of Shore Face, which is Lambert Transition
47:25 , which is language of the pro offshore. So the reason that you
47:29 put a transitions Joan on top of because because they were next to each
47:35 , that makes sense. That's wealth law. The only reason you could
47:40 a beach or foreshore on top of shore face is because they lied next
47:46 in cross sectional view, so the of next to each other could be
47:51 vertically in a vertical strata. Graphic Now this vertical strata graphic section it's
47:57 getting sand here upwards. There's less upwards on the environments, and physical
48:03 are recording more energy as the environment shallower. So we see a Siris
48:09 parameters that are changing gradually from the to the top of the faces,
48:15 or faces Association on the Faces Succession just a title word for a vertical
48:24 association versus a lateral faces association. also used the word faces sequence to
48:32 this, but in a sequence to class way, want to avoid using
48:37 word sequence because you might get confused a deposition of sequence on the facing
48:45 . Totally different. Hardworking heads turn sequence for this feature versus sequence.
48:52 this contact here violates. Ralph was , right? Can anybody tell me
48:58 that surface violates? Wolf is who feels like China in it's because
49:07 them conformity. Instead of going back four short transition zone, you go
49:12 thio offshore environment. That's exactly So so so the environment that's next
49:19 environment. So basically, this is a transgression. If we have a
49:23 transgression the environment that that's next to foreshore as you go deeper, it's
49:29 shore face. So if this was Roth assault transgression above the foreshore transgressive
49:35 , we should say sure face then zone and then offshore. That's not
49:40 we see. You see, deep mud stones, sharply overline foreshore at
49:45 stroke supported out that that z maybe a nonconformity. It's certainly a dis
49:52 , right? There is something missing that contact. And the fact that
49:56 something missing means that we tag that a critical surface to sequence integrity.
50:03 what kind of a surface do you that would be floating surface it Z
50:14 it. Za flooding surface. You call you could call their transgressive
50:21 It's not the transgressive surface that that's more important transgressive surface. Okay,
50:28 me, doctor, but yes, cannot see your screen. Would you
50:33 share again? I'm unable to see screen. You sing it there.
50:54 e. Okay. Uh, So I'm gonna do is that Can you
51:34 that you still don't see on the there, Maria. No, I
51:37 have any screen. I just get message. You are reviewing Daniel
51:43 Daniel, would you please leave the ? You might still be on the
51:49 share, so maybe, um, not a screen share. Like it
51:56 ensuring what my, uh What? going to record the rest of this
52:21 . Uh, hopefully it's recording my . Not sure, but,
52:27 well, workers began at least way up with recording. At least you
52:33 have the slides. Right? So we'll get through it. So the
52:38 of Paris sequence was actually originally came This concept of a parasite group,
52:44 was a memory of what you might to do, is just log
52:47 log back in again and see if screen shows up. If that
52:52 it's Maria. She's response. Of you can't. Might mean that means
52:57 slides. So that's why they're It's not that you can't see
53:00 so yeah. Yeah. Okay. meeting is recorded again. Forced to
56:14 on the lower drive around shows much same thing. We've got,
56:21 mud stones here. The base. , course an upward. There's a
56:25 contact. There was going to get stones above sandstone below thes sand stones
56:32 get out of our debated sandstone storm . So this lower Paris sequence is
56:37 bit more disturbed than this upper Paris . But the idea is you would
56:41 we have up, of course, faces successions with a sharp contact that
56:46 deep marine mud stones over a shallow , of course, and faced
56:50 You will notice that the transgression Okay, if we exit the
57:00 Okay. On. Give me a here. Oh, never mind.
57:21 uh. If you look at it closely, get here is the cross
57:27 , uh, upper short base and deposits. They're overland by PETA.
57:32 channel faces. What you'll notice is the top? There's a sharp contact
57:38 . Guys, get Melissa pointed back again. And there's a little unit
57:44 bar debated muddy sandstone that erosive lee threat that Miro Sidley over lies the
57:51 laminated beach departments. And there's a contact that separates laminated mud stones
57:58 That represents the distal procreation of toes the pro delta of the next
58:03 Paris inputs. So that's a down surface that's a transgressive surface of
58:10 And there's about five centimeters of transgressive that's very thin, that that five
58:17 10 centimeters of transgressive bases is invisible , but it is clear on the
58:23 Okay, so that's so That's so service marks the end of termination.
58:29 come ripping across that short base. deposit a little rework, transgressive deposit
58:36 , then that's the end of the on. Then you have the procreation
58:39 toes of the next Harrison coming across top. That makes sense. Now
58:48 could look at what, uh, , walks a modern delta on we
58:52 , it shows the same upward coarsening . So here we can see nice
59:02 the coarsening Well, our profiles, get a little bit muddier as we
59:07 from central adult it that flanks the , a little sharp based here nevertheless
59:13 coursing upwards here and even here this upwards. But we're now,
59:19 this well is now off the main load on. So we got a
59:23 more money laterally muddier succession. This anomalous. It looks like it finds
59:30 that that's kind of right in this here that probably represents the distributor,
59:35 Channel, that's feeding the delta. once again, we see it up
59:39 course in the unit that's founded by readily coated correlated the surface that separates
59:44 faces above from Sandy below. of course, marks foreign service.
59:54 there is a lot of debate right as to what in Paris sequence is
60:01 Paris's Autumn Janet, whether it's allergy as originally sort of envisioned and visited
60:10 Wagner and company. You know, river comes in Ontario and use Delta
60:19 a regulation of delta. Then maybe river goes somewhere else, so this
60:26 is no longer being supplied with And so it becomes transfer that the
60:33 front sand reworked into a transgressive barrier overtime. During every during every
60:41 some of the sand is shunted into back barrier. Some of the sand
60:46 offshore because because of off compaction of , this barrier island, let's just
60:53 graded graded. No sentiments being supplied it. It gets totally by
60:59 In the end, you just get spin, are debated sand that used
61:04 be a nice barrier island. that that is the reward remnant of
61:10 used to be a delta became a attached barrier. Uh, short face
61:18 that land detect barrier has finally something ways to become a shallow marine,
61:26 shallow sand show. Uh, the is, that is that Delta's go
61:30 the cycle off active build during during progressive days on, then gradual transgression
61:36 abandoned during the abandonment phase, which records the flooding of the delta as
61:43 switches somewhere else on this is a oughta genic process. Over the
61:51 who, 7000 years, the Mississippi shifted course, and the river has
61:58 over that 7000 years, resulting a of lobes that compensation in snack.
62:05 , 7 8000 years ago, the I, uh, that sale
62:11 uh, low was deposited. That switched over here load number two,
62:17 is the Cocodrie. Then it switched position three, which is Tesh,
62:22 the position for which is a simpler delta. Then the position Position
62:27 which is the push. Uh, the six, which is the the
62:33 means Delta on that evolved into the Belize Delta, which is the active
62:39 on now, once again said in beginning to switch back to a
62:43 I've a with the chapel. I late fifties that all those lobes have
62:49 shifting around over the past 7500 We could visualize that using a time
62:57 diagram. So this is a wheeler on the right hand side.
63:00 We've got time on the on the axis going from 9000 to 1000
63:06 So there is the oldest Delta. , what I call it before sales
63:13 mourn or otherwise called the Marron Okay on then, uh, Then
63:19 , uh Then there is the youngest that they're the modern, uh,
63:24 out with all the other ones in . And you could see that Delta
63:28 in terms of the young direction A to the physical position because they switched
63:33 all over the place. There is sometimes between some of the dancers.
63:37 Delta six has grown at the same a step to seventies. But the
63:41 last load of 15 is too positive after low seventies deposit. So these
63:47 delta complexes have broken up into small deposition load. This was all figured
63:52 by Fraser in 1976. Frazier was Exxon researcher on Fraser heavily influenced Bill
64:02 on this, this is a kind a complicated diagram way. Have a
64:06 of dip cross sections. Okay, these are the cross sections of the
64:11 forms on the means of the wheel . Again, with time of vertical
64:16 on physical position on the horizontal this shows where the faces are in
64:21 and tone. We'll come back to and other lectures. Here is a
64:26 strike diagram representing this cross section So the cross section shows overlapping of
64:31 lobes on, then shows how they located in wheeler space. So there
64:37 the oldest man you unload. there is the chapel rights Lakes
64:42 and you could see that there is of shifting around all over the
64:45 So what you get is, for , a well here, one of
64:48 big gap of time from the man you in to the 14 with Bush
64:54 that gap in time in this position bases report by Delta sedimentation elsewhere
65:03 Now, the other thing that John Wagoner noticed is Paris sequences were organized
65:09 systematic sense. Okay, And and comes to this idea of stacking
65:18 which by now should be a familiar . Thio. This is simply This
65:23 sort of the beginnings of the idea accommodation successions what Neil Bro said.
65:29 like things. Concept of aggregation, procreation or degradation or retro gradation.
65:35 patterns could be applied at that scales than the smallest Harrison's, we platforms
65:42 stack and sequences construct. So they said, Let's stop using more Paris
65:47 comparison set because things were great but they could apply it all
65:54 Uh, but the terms came from observations of stacking patterns off faces,
66:00 on our crops and corals with this called the Paris includes. There is
66:06 drive in the community right now to rid of the war in Paris,
66:09 I'm not a fan of that There are people who don't like the
66:13 Paris. There's nothing particularly complicated about , its simplest. It's it's just
66:18 of these. It's one of the up with successful reforms is a Delta
66:22 shoreline programs that zoos how they're sort fundamental defined now. The trick is
66:29 they're defined as thes open storing successions bounded by flooding surfaces and their
66:38 surfaces. So that means, you , that they correlate into the non
66:42 and it is the beaten. But lots of debate as to how easy
66:46 is to identify Paris's works when you're away from these shallow Marine faces.
66:52 that's a topic for discussion Aziz later the class. So what they noticed
66:58 it could be retro gradation or the they could stacked vertically on. They
67:03 stack in a probation or see with , and, you know, they
67:08 down step taken steps. They, uh, you see where for stepping
67:14 , flapping. So all these terms of a now there's truth is true
67:20 here, so the cross sector shows overall cross section of architectural, Harrison
67:26 . On then, what's intriguing is . Right hand diagram shows comparison from
67:32 has a unique and specific expression in dimension that's potentially very useful because sometimes
67:40 may only have a couple of so the idea is well, if
67:44 serious? Serious in Paris inferences. looks like they get bloodier upwards.
67:49 might indicate a retro traditional Harrison's. you have a serious of vertical Paris
67:55 and seem to get sand, your words that might indicate appropriation of Paris
68:01 . And you see a series of Paris sequences all have about the same
68:05 of sand, the stereo and similar that might indicate aggregation of Paris is
68:11 , and ultimately, what we're gonna on what you've already done is you
68:17 know how to translate a P or , a R or D to a
68:22 tracked. So the idea is that you could predict the systems tracks the
68:28 from one the observations of stacking Now that's dangerous. But it's also
68:34 because it allows you to make Even there may be some risk.
68:40 last thing I want to say about diagram is the idea. If you
68:43 procreation, flood prone nation of flood , flood propagation of flood.
68:51 Now, if you can imagine, , if you can imagine,
68:58 a, uh where's my screen Is that now? If you can
69:09 , you know, a Delta. ? And a river is moving.
69:14 a delta. Okay. And then then and then the river verses.
69:22 another Delta. So this area's transgression transgressing. While that area is
69:28 that e beats another delta. this is regressing. That's transgressing.
69:37 , then it builds another delta, ? And that is regressing. While
69:41 areas have continued a transgressing Okay, that's gonna produce is a syriza clown
69:49 that would progressively step seaward. Okay flooding in between flight records, the
69:55 genic lateral abortion of the river with flooding during the substance of the Delta
70:02 while regression continues. So the overall overall stacking pattern is progressive and
70:09 producing a pro gradation stack of But individually, each one is his
70:18 by automatically produce flooding cities. Way think about alternate scenario. Where,
70:32 we have excuse me, where we you know, Delta, it's
70:43 Then then the river fonts. But an overall transgression with Nextel that doesn't
70:49 us far. While that's flooding, there's another transgression. Another eveld.
70:56 , but there's continued flooding. So this case, we would get a
70:59 of uniforms that progressively stacked landed, a retro gradation. All staff says
71:06 . Each delta is over, led a little internal flooding service. Those
71:10 jen. But the overall Staten reflects allergenic forcing because of what they're a
71:17 . This original based opportunities. So would argue, quite strenuously, that
71:26 the flooding circle is flooding surfaces as in the original definition of parasitical set
71:32 Jan Wagner, more or less assumed the flooding service were auto genetic in
71:38 related to things like Delta Smoke Scripture Mississippi about you. There's a lot
71:46 people that disagree with that. I with me strongly. Right now.
71:52 respect him to screen with them. may return to that debate tomorrow we
71:59 . And, of course, the off Harrison from Staten Patterns we
72:05 revitalized by Exxon, particularly with Jack , Veto bro. Both of whom
72:12 . I think they were for, , Peter Bales, last graduate students
72:17 Rice University. They were both. were sort of the last well trained
72:23 the last of the sort of excellent seismic photographers. And they said,
72:28 a minute, we're not working walks John Man. Wagner is you
72:32 way want to use thes the aggregation reparation of terms for seismic data,
72:38 we're not allowed because units were using much greater Paris sequences. And so
72:43 Bloom said you guys invented the terminology it said, Okay, we're gonna
72:47 gonna invent new terminology, accommodation, , that that gets away from being
72:54 specific. You can have a combination at any scale, whereas a para
73:00 had it has a bit more scale with. Okay, so So I've
73:11 of talked about this, I think a bit. Uh, the next
73:15 of slides just go through each of in detail with some examples. So
73:21 let's look at appropriation. All Paris sense cast question before we get into
73:28 . Okay, So when you're looking the electric log on the right there
73:33 it's showing the resisted curve on the and it shows a resist 70 spike
73:39 the top of the sand, are are they assuming that there are hydrocarbons
73:44 these sands? Because of that spike the top, it's hard to know
73:49 they're assuming. I think that's what what's fair to say is there,
73:53 the fluid content is unchanging. You , things obviously, is not a
73:59 of analysis force, but you're absolutely . Resistant log is extremely sensitive to
74:06 . And so if that was a wet sand, it would. The
74:09 study law would not look like So for the sake of this
74:14 waken assume that the fluids were either same. And the diagrams sort of
74:20 that sand stones of resistance that will true for Santa types and had no
74:25 and them so cemented sandstone typically have resist emit e, but then they
74:30 have any SP response. So, know, if you want to cross
74:34 out and call that gamma, you're better off, right, because these
74:40 more like Gamba logs and SP and you could take the reason sitting
74:44 the greater salt. Does that Does answer the question? Yeah, I
74:48 just I was just looking at and e didn't know if it's common
74:52 the resisted Biti to behave like that a blocky sand where you could get
74:58 a fake out. You know where think maybe there's something there there's not
75:03 is resisting what it depends on. you're talking about the shower versus deep
75:08 , that depends on the restricted withdrawal . Okay? I mean, I
75:12 about that extensively in trouble ideology. realized something. You haven't had
75:18 But, uh, you know, something probably you're gonna you're gonna have
75:22 revisit when you take for those things haven't had done. The patrol,
75:27 here, Roman forces. That's a question. And JD is absolutely,
75:31 right, you know, thes thes schematic. Well, well responses
75:38 They could be very different in real . But for the moment, let's
75:42 that things are mostly hard to carbon and that the sand stones of pretty
75:47 . Which is when you have to response like that. Other questions.
75:55 , It's a recent example of some that I did, and I'll review
76:00 again. Uh, probably tomorrow. have our lectures there, and what
76:06 can see is, you know, questioning Paris sequences. Those were pretty
76:09 . Uh, sometimes you've got short and stones thes paris sequences, super
76:15 up, then horizontally, and then degradation right on, then, overlying
76:20 is a thick package of four screen deposits. It seems to have a
76:25 surface, but it's everywhere eroding into shallow Marine Department. So can anybody
76:31 me what this would be in terms accommodation? Successions based on the line
76:35 I draw Susie? Correct. That be aggregation, ALS determination ALS
76:42 then maybe even to degradation at the . Good answer. Faith. Here's
76:47 example from the from the the bandwagon , you know, and you could
76:52 any point, like, sort of of sand stones is here. That
76:59 kind of here, right? And that would define what kind of a
77:03 Succession. Yeah, that would be very good. So overall, procreation
77:11 but sort of more p today if should take the You know, the
77:14 part of the sands may be here little harder. You get more or
77:20 the same thing, right? You pick that point, you know,
77:24 you could pick any faces boundary and of tracking little Russell telling about the
77:28 succession with this. Right on. , you've got non marine material accumulating
77:35 shorelines, indicating some aggregation component to appropriation of Harrison said. And there
77:43 an example from the book Cliffs. here we can see a syriza.
77:46 precautions, units. Okay, Looks like they get a bit muddier
77:51 find a great upwards. Then you a fix shale on, you get
77:55 on. It's pretty clear that they sandy up upwards, and then you
77:58 a big, blocky sand on Okay, so this would be sort
78:02 a increasingly thinning and finding set of , Paris and cassettes with the turnaround
78:09 a set of thinking up with Harrison on that would define what would this
78:14 ? Things group. What would be combination succession there? Okay, while
78:25 getting money or upwards, but not thickness. True condition. Yeah.
78:31 that would be our then about that be, Yeah, these ones getting
78:39 upwards. So therefore there ap right. Yeah. There's actually big
78:45 or conforming their Republican. Your service , in the hang of it.
78:51 so obviously parents equals stacked vertically. you know, the well, long
78:56 looks something like this. And again d will recognize that you know
79:00 These are all showing five restricting sands , you know, that could be
79:04 case, but it would be very on the content. So if you
79:08 that with a grain of salt, is an example from the textbook that
79:13 a series of Harrison consistent showing relatively succession of Paris instances. E noticed
79:19 ones showing nice coarsening of words that of these other ones final. So
79:25 , you know, then that courses . So, you know, data
79:29 always messy, right? So it not necessarily perfect. But it illustrates
79:34 idea that you brought a stack of stacked sands here. It's mostly all
79:40 here and here It looks like it's Sarah Marie. Then here you could
79:44 got shallow Marine to Mom Marine and to show. So basic aggregation of
79:52 on. Obviously, when things get upwards, Uh, that's the classic
79:58 rotational combination Succession, or Paris he on here on the lower diagram is
80:05 set of back stepping Harris sequences. , I believe, from the,
80:11 , shop who basement Wyoming. That's almond sandstone. I had a graduate
80:16 units and nice, uh, Mr on that unit. Some years ago
80:22 been about there. We just have couple example of classic appropriation or Paris
80:27 sense. Uh, in this case thes thes quotation examples from the Western
80:34 see way of North America. So summarize, you know, thes stacking
80:41 could be seen cross section and they have, you know, recognizable
80:47 long patterns and the the next starts exercise. I'm gonna give you eyes
80:56 be a well log and you'll get chance toe look at the stacking patterns
81:01 put some flooding surface sequence boundaries and some one dimensional superscript a gritty.
81:06 go through the exercise, um, this afternoon. So he's just an
81:12 of one dimensional well, long on here, you know, it's
81:17 It's kind of maybe getting sandy That's kind of noisy, so that
81:21 be appropriation oppressed to set going into . All here it's presentational back
81:28 improvisational, back stepping thistles, improvisational presentational to back stepping. Here's
81:35 Carsey consent. There is a rotational consent and so on and so
81:40 So the idea is that you may to identify these Paris super stacking patterns
81:45 a single well off have accepted. we get to sing well or it
81:50 get a little bit noisy, say Sergio Point, JD. Here's the
81:55 of Sydney wogs and there, you , sometimes you get low recipient sand
82:01 . Sometimes there's a slight increase Of course it Z's role. These
82:07 all this is all short focused data . But that one on the right
82:14 more like what I'm used to seeing one here. Yeah, it's not
82:20 crazy with this to be at the of the sense. Yeah,
82:25 And of course, In addition to Harrison France's well logs based on the
82:32 , stack of ceremony faces successions way also look at cloud a form patterns
82:37 how they how they're organized in cross of space on This is something that
82:41 folks now have done twice. I you've all done it anyway. Everyone
82:47 certainly finished. Exercise one. I most of you have made some progress
82:51 exercise, too, or you've been Theo organization platforms in the cross section
82:58 to refer whether they're a p p aggravation recreational s. So I think
83:04 getting behind of that e talked about quite a bit, uh, during
83:09 first couple of lectures and then we about the idea Identify these pants Seismic
83:15 . So I'll just show that to you of what we said last week
83:19 then, uh, again, here just another example. And then,
83:25 know, there is a provides er so here is the unfortunate situation where
83:32 have a Siris of of a progressive rotational Delta's okay, but this stuff
83:40 set is moving laterally away from from well and towards this weapon. So
83:48 This while scenes is the adults is moving away. Show it. It
83:53 a muddying up repetitive. Okay, well is seeing the Delta Larry migrant
84:00 it. So it shows an overall in sand and success in Paris.
84:06 that would look like a probe. Harrison consent. This would look like
84:11 retro creation of Harrison consent, but fact, in plan view, it's
84:16 pro operational, for you're starting to stacking patterns that reflect lateral migration of
84:24 . That's attentional noise so noise can up the interpretation of stacking up in
84:32 lower case we see exactly opposite here is a series of Delta's moving
84:37 with tongue. There's a well, in a while. They're so Taiwan
84:42 Delta's far away. So it's got little money up. Of course,
84:46 . That time to Delta is a closer, so it's thicker time.
84:50 with Delta's right on talk. So a big thing San Delta that looks
84:54 nation over. In fact, it's because the Delta is laterally migrating closer
84:59 that point, even though it's stepping or transgressing over time shows what looks
85:05 a fermentation. Was that Harrison But in fact, in plan
85:09 it's actually reputation so way have Caution with the interpretation of Staten Pendant
85:16 that provides or makes sense to everybody little, little certain that, of
85:22 , parents eat what sets are bounded more extensive surface than than Paris
85:29 And one of things that we do out is that you know all
85:33 uh, retro pronation aggregation of termination pressing sets way have regression in all
85:40 them. So even in the retro or Paris even set, which might
85:46 a transgressive systems tracked, you could get regression recurring, uh,
85:51 In fact, you could say, , all the faces of aggressive on
85:57 regressive Paris sequences about it by flooding . But the stacking indicates an overall
86:02 work migration off each aggressive Paris This is why people sometimes get confused
86:09 Mohammed's transgression is occurring in a retro of transcript in a retro creation of
86:15 said, that defines a transgressive systems with all the faces, a
86:19 aggressive. I'm confused. Why you that transgressive when all the faces of
86:25 the answer is defense. They're stacking an overall, the retro gradation pattern
86:31 in a global allergenic transgression, even regression for local so that sort of
86:39 them. Having said that thes large , direct operational present consent are the
86:46 of them all, some of you have noticed your assignment run that there
86:51 very little bonified wreck tribulation going It was more just a big
86:55 Sisters, even in assignment to you'll that your finished systems track was transgressive
87:02 track. That's that's generally an I found truth. Okay,
87:12 how do you guys do? I like it's It's maybe time for a
87:15 little break here. Um, so don't we just take a little break
87:25 , uh, recording has stopped. , so Maria and I are both
87:30 this. Uh, that will also us a chance to be set.
87:35 I'm sure. Maria, were you my screen ships? But this time
87:42 , Yes, yes, yes, now. But the recording was stopped
87:47 now. Why? Please give me to continue. E. Yeah.
87:54 just gonna take a break. what time is it? 4.
87:59 started. Get 4. 80. start again at, uh,
88:03 30. What time? That's going 30. Sorry. Start back
88:08 Is that okay? Uh, I'll keep my eyes. Your mom and
88:13 guys just, uh, come back you get back out of it.
88:23 .
