| 00:00 | Yeah. Yeah. Uh huh. . Okay. Uh We have left |
|
| 00:18 | continent more specifically continental deposits. And we're now in the marginal marine and |
|
| 00:26 | gonna start with tides, I don't we'll do anything more than tides |
|
| 00:31 | Uh They're going to waves will go uh barrier islands and estuaries and finally |
|
| 00:39 | . So that is the material that be uh in part the basis for |
|
| 00:46 | next exam. Okay, well then up with deepwater sentence on that followed |
|
| 00:53 | . The third exam, we'll have half of it tied to material from |
|
| 01:00 | and then the other half kind of material before. It's a little hard |
|
| 01:06 | differentiate that though because some of it be comparing maybe meandering alluvial rivers and |
|
| 01:14 | submarine chance. So uh they'll be and contrast that may be looking at |
|
| 01:23 | from the earlier exams with things that going to come in the next three |
|
| 01:28 | . Okay, So if we look tides, they are but one of |
|
| 01:32 | year basically determine the coastal deposition are in reality all of these errands to |
|
| 01:43 | extent or another, perhaps the exception uh affects on all coastal sex. |
|
| 01:50 | it's really the relative importance these various that I want to focus on and |
|
| 01:58 | specifically their sentinel logical record. So we can go into the rock call |
|
| 02:06 | uh those influences of tides versus frugal input, et cetera. If |
|
| 02:14 | look at the title range globally. of the things that you'll notice is |
|
| 02:20 | there is not any obvious lack. control. Unlike let's say whether or |
|
| 02:29 | for which there is at least some control, we don't see that uh |
|
| 02:37 | and art because the tied and more titled application is often associated with changes |
|
| 02:45 | the width of the shelf. And a lot of the very high tide |
|
| 02:51 | are areas that have very broad shelves in some cases the shape. So |
|
| 03:00 | they are less sensitive to latitude new um reclassified the title setting of a |
|
| 03:12 | zone based on some measure of the of spring tots. Um So in |
|
| 03:19 | particular case, uh if the these tides are less than two m, |
|
| 03:26 | micro Tyler to the four metre vessel For macro title although increasingly uh splitting |
|
| 03:39 | that which is greater than six So there are some pretty large tidal |
|
| 03:48 | is that we can be dealing And uh our say now it turns |
|
| 03:57 | that as you go from these low high tidal ranges, you have a |
|
| 04:02 | in the mix of deposition elements. for example, our barrier islands, |
|
| 04:12 | melters tend to be in the lower uh beginning to higher ground and peter |
|
| 04:25 | uh Those tidal inlets actually increase a bit as we get increasing times until |
|
| 04:33 | point as they made against theater as . In the associated title devils, |
|
| 04:41 | l there peter yell replaced are the out of flats with increasing uh increasing |
|
| 04:50 | marshes and finally these subtitle sand So this is a particular port because |
|
| 04:59 | we think of the san geometries, until not long ago, our major |
|
| 05:05 | reservoirs, the microphone and that's basically around where is up here where you |
|
| 05:16 | get your title shows and tidal flat , uh it turns out that waves |
|
| 05:26 | also important component. And so to extent we have way dominated tried dominated |
|
| 05:36 | settings depends really on the relative importance ties versus weight. So that the |
|
| 05:43 | based on micro title macro title is better modify its like because you have |
|
| 05:51 | low tidal range, that's a very wave energy. It doesn't take much |
|
| 05:57 | a title range to give you a dominated set. Conversely if you |
|
| 06:05 | there are also always right. Uh no text higher, higher nadal brings |
|
| 06:15 | . So basically we're gonna be talking three kinds of coastal mythologies. A |
|
| 06:23 | dominated Next Energy I dominated cultural Now when we look at title |
|
| 06:31 | we're basically talking about a title Uh and it's going to have a |
|
| 06:38 | and a flood velocity that lost in direction can get does here high enough |
|
| 06:51 | transport sense and didn't say so any the title loss sees the critical |
|
| 07:01 | You think about last year. You that you start uh your loss, |
|
| 07:07 | can have transport center flood transported It turns out though a perfectly symmetrical |
|
| 07:20 | the way it is actually kind of particularly as it is getting into the |
|
| 07:27 | shore councils up. Instead, we to have a wave of a tidal |
|
| 07:32 | velocity cemetery where in this case the component being dampened, the being |
|
| 07:43 | Now, in reality as much water gonna move in with the times is |
|
| 07:47 | move out. So you might how did this happen? It happens |
|
| 07:52 | you're segregating the channel ways for the water. And therefore the set of |
|
| 07:59 | transport into every dominated and flood dominated . So we're going to have some |
|
| 08:07 | that border abdominal and some there will more flood up. Yeah. |
|
| 08:16 | what we tend to think of when think of title sediments and sedimentary structures |
|
| 08:22 | hearing, bone coster. Mm That based on the idea that we got |
|
| 08:30 | tides and directions. Yeah, they're enough. Equally important. So that |
|
| 08:36 | get left right flood and transport and do get that. This would be |
|
| 08:44 | example uh carry the cross strap. but it's actually not as common as |
|
| 08:52 | think. Uh mainly because of the of end and flood flow. |
|
| 09:00 | although it certainly is a right product a tiger wave. And we're going |
|
| 09:08 | look at variations on this theme as look at the title set. It |
|
| 09:15 | much of the original work was done the North Sea. Uh So here |
|
| 09:20 | an example with no from marsh down Time channel. And you can begin |
|
| 09:28 | say in addition to the the a lot of brittle sand. And |
|
| 09:35 | the rippled sand. Another hard to but assassin metrical. So this is |
|
| 09:41 | current dominated ripple. So that already that maybe this is a area they |
|
| 09:53 | a flirt for tom. Uh, course there's the channels. Well, |
|
| 09:59 | when that sand moves though, it's then followed by a period of |
|
| 10:04 | water by which mud drapes that And not only do we have rippled |
|
| 10:12 | , great mud, but we have lot of bio probation because these |
|
| 10:17 | that's our areas high biological activity. . No, let's go back to |
|
| 10:26 | title velocity. A cemetery and look that rippled sand Madrid. Yeah. |
|
| 10:40 | , uh, in this particular uh, let's see here we have |
|
| 10:47 | migration. The ripple migration stops and had my deposition and you didn't have |
|
| 11:00 | reactivation reference what deposition. So for flood and the cycle, we actually |
|
| 11:13 | the taverns called a title rhythm That gives us to sand movements, |
|
| 11:20 | in each direction separated by mud Now, if you have in this |
|
| 11:29 | , in a more flood dominant you might always the next moment title |
|
| 11:40 | exceeding critical sand threshold in one So here we have the title rhythmic |
|
| 11:48 | got mud, sand bud. the net result of all of the |
|
| 11:57 | of changes that go into the type plan is that we get, oh |
|
| 12:02 | called a hetero lipstick or mixed bet sand blood sand much and in this |
|
| 12:11 | it's rippled sand and mud drapes. if you look at this hetero listed |
|
| 12:19 | you can have dumb blood sand holly . Can we split that in three |
|
| 12:29 | of day? And then take it little ripple lenses way which is basically |
|
| 12:38 | but ripple tops given this lady look same thing inflation just basically the only |
|
| 12:47 | that you get is sitting here control is not enough. So here we |
|
| 12:58 | pleasure bedding. Uh huh criminals going both directions but live at a hit |
|
| 13:07 | that remnant cut. And this would an example treasure that there's a piece |
|
| 13:14 | it here. There's a piece of piece here. Uh I have the |
|
| 13:21 | uh image. Treasure daddy. But see how this is discontinuous so that |
|
| 13:28 | be predominant the same. Thank When we get into late events reaction |
|
| 13:36 | saying we'll continue but great. He's Tripplehorn giving the way they look. |
|
| 13:47 | that with here, let's see how rippled sand is continuous. Team. |
|
| 14:02 | your and chickens and pigs. Yeah last thing is we have basically started |
|
| 14:10 | just not enough sand in motion to form us. Here's that lady. |
|
| 14:19 | the dancers. He had this little . Uh huh. And of course |
|
| 14:27 | you can see from these outcrops uh can get a lot of vertical very |
|
| 14:34 | . Having said that there are certain patterns that we can see here |
|
| 14:40 | You see this triple form baby Not much inflation here. Uh This |
|
| 14:58 | highly variable seat modified by has has much of that uh city here as |
|
| 15:08 | . Now depending on the area these rhythm eyes can be pretty much all |
|
| 15:21 | single elimination, tired of sites written . Uh Maybe that mary can't. |
|
| 15:37 | . You mentioned earlier that we tend classify the entire range based on |
|
| 15:47 | springtime education. We all during the where the spring where the solar and |
|
| 16:01 | ties phase dampening. So that over 28 day lunar cycle we're going to |
|
| 16:09 | two knee hops into springs. So you start healthy, the 50s are |
|
| 16:20 | of little lamination, the major they tend to pick it and swell |
|
| 16:29 | a 20. So what we're looking in this particular case Alright offered to |
|
| 16:37 | him here um Our spring unique title defined by title ones. And this |
|
| 16:46 | one of the unique properties that we to identify tightly influenced sedimentary structures. |
|
| 16:55 | here we have some types of this one is a. I. Uh |
|
| 17:05 | . Rather two hours. Uh You can have, we could have |
|
| 17:14 | explain as we showed you last time even look at longer here going into |
|
| 17:24 | Year cycle. So all of these be seen patient uh recorded in the |
|
| 17:32 | . We also showed that ties. the annual cycles of custom bars. |
|
| 17:39 | to that extent bars. And these rhythm mites are those body water. |
|
| 17:53 | just have to be connected by the . Okay, so no lakes, |
|
| 17:59 | don't have times uh, distinction now said that they have, uh, |
|
| 18:06 | set were called wind tops. So can have set up and sit |
|
| 18:12 | uh, are caused by wind. you've disconnected yourself world's oceans, you |
|
| 18:19 | have time. Oh, some So here we have a measure. |
|
| 18:30 | this was entitled writing up the results tightly influenced self and take a look |
|
| 18:41 | these arrows. If you look at closely, we can actually see nytimes |
|
| 18:52 | . So, uh, this kind variation. Hear hear CS get |
|
| 19:00 | We get these spring calls you with case and migration on larger days. |
|
| 19:13 | , so we could look at the of a title wandell or we could |
|
| 19:20 | the thickness of rhythm might its power light or as was shown a |
|
| 19:25 | we can look at the thickness of package of doom as it migrates called |
|
| 19:32 | time bunch. Okay, again, are unique features that we're used to |
|
| 19:40 | the relative importance of tides in classifying system. But now we also talked |
|
| 19:48 | what happens when there's a reversal of . Uh, and that is one |
|
| 19:54 | for a reactivation service. So certainly services hard for in this particular. |
|
| 20:02 | . Uh, pretend and then we temptation deposition attack. It starts |
|
| 20:17 | Yeah. Now that doesn't mention So maybe we don't look at a |
|
| 20:23 | bit, look at what happened to dudes. Now we're no longer |
|
| 20:28 | Certainly shallow water just rip. Let's into a little deeper water. Maybe |
|
| 20:34 | channel. Okay. And higher velocities we actually get into uh, dune |
|
| 20:42 | forms and it's going to be the kind of bed phase diagram we talked |
|
| 20:47 | earlier except that. Now we're looking maybe a six hour Community direction of |
|
| 20:55 | , 12 hours in the direction of company. Still think of the increasing |
|
| 21:01 | resulting in a change in that So here we have, Hey |
|
| 21:09 | I'm ready not created. Uh, here, don't show anniversary. This |
|
| 21:17 | sent uh, support. But what at you? The loss slows down |
|
| 21:26 | stops you getting great. And although is a blood, it's very |
|
| 21:33 | Your biggest off of the feet Then we've got in reverse. We |
|
| 21:43 | a reactivation of holes. Yeah. there, Hey, well positioned |
|
| 21:56 | So flood rip, flood sand, deposition, mm, sand, position |
|
| 22:06 | one home tidal cycles. And that's we call a title run on this |
|
| 22:14 | , but we can look at that where we got this, my great |
|
| 22:28 | that's truncated here by reactivation service. is for me is okay. So |
|
| 22:48 | what we're looking at. The only we don't see is the love. |
|
| 22:54 | let's go to an example. Look surprise. Uh here is on the |
|
| 23:03 | . So this is the dude is migrated to stop vibrating, stop. |
|
| 23:12 | . Now what we got to see those caps, they tend to be |
|
| 23:17 | writer. So they have very low . So the dominant aw yes, |
|
| 23:25 | what it's going to be. The that determined debt direction. Uh |
|
| 23:36 | Yeah. The amount of migration of depend on how long and how strong |
|
| 23:45 | dominant search. So during spring time will be larger. Whoa. During |
|
| 23:54 | tax. Yeah. So forget the of these tight abundance. A standard |
|
| 24:08 | . Now, if you look at of the let's look at the ball |
|
| 24:12 | here. Yeah, that's sitting Like this actually still here. |
|
| 24:23 | If we look even more closely what see is Mhm mud. Here are |
|
| 24:39 | ripples, mud, here is mud. Mhm. So, in |
|
| 24:48 | particular thing uh reverse, right? , these may actually baby bills. |
|
| 24:56 | set, christian what we've got Uh And so this again is |
|
| 25:11 | Yeah. Double. You have multiple out sets are lying nasty, |
|
| 25:22 | History entitled nominated centres. Now, is the time going losses. All |
|
| 25:38 | . I'm like this is death. is the box. Mhm. Uh |
|
| 25:49 | . Don't be too concerned. This here a lot. The forward |
|
| 25:56 | Stop it, Right? It accelerates . So this is one type of |
|
| 26:09 | away. Uh the relationship the phase the water, the phase of the |
|
| 26:18 | varies anyone wanted progress, understand that's important. What's important is this part |
|
| 26:26 | we have accelerated lawfully? Yeah. yeah, there is a critical |
|
| 26:38 | maybe 37%. It's necessary to reactive so no motion is occurring of the |
|
| 26:52 | part. Now we reactivated, said we're beginning to get four cents. |
|
| 27:03 | is getting my But look at the or anger our call go back to |
|
| 27:13 | we talked about earlier that anger four was associated with Northern law states less |
|
| 27:20 | itself. And then as the dude water and going to the height of |
|
| 27:29 | , we began to go to and again we saw that the correct therefore |
|
| 27:40 | dunes is in the higher losses. then continue to go there on |
|
| 27:49 | This is just like uh and they With back from sustained seven. We're |
|
| 28:02 | to go on the we lost but a lot of suspenders begin to drink |
|
| 28:13 | . Yeah. So I'm gonna have saying morning set. Yeah, can't |
|
| 28:23 | black, black things easy enough to Next to the biggest six wars. |
|
| 28:29 | huh. He's going to be something Yeah. Yeah. So now what |
|
| 28:42 | done is we've taken that time a and we look more carefully based on |
|
| 28:48 | nature of the that sets and enforces look just how strong was that type |
|
| 29:01 | then there's mud drapes of the Well and and so this is what |
|
| 29:11 | extreme bar might look like if it trash. Uh and then within this |
|
| 29:19 | one to get these Example The 2nd notice the title bundles are getting smaller |
|
| 29:29 | we're going from Supreme had an Mhm. Now the other thing is |
|
| 29:40 | . Nytimes. No. Yeah. Let's go ahead. Uh huh. |
|
| 29:56 | many types of spring greek tides by elevation water is less or a maximum |
|
| 30:11 | . Therefore the games are gonna be . Transport. Is this for with |
|
| 30:18 | title? Re forgetting increasing awesome. we're getting larger mortgages. So they're |
|
| 30:26 | only being transported cargo but the So we get why me narrowing |
|
| 30:38 | They also get maybe shall people in spring meet titles. So here's again |
|
| 30:49 | example took this kind of honor trade . Yeah. And you can |
|
| 30:58 | Yeah they should certainly. Damn Yeah. Huh. Uh huh |
|
| 31:09 | And almost no presentation of uh in case the blood kids because just as |
|
| 31:19 | reservation now there's a term that you into called inclined prolific strap or |
|
| 31:30 | H. S. And that's basically we've been looking at in the title |
|
| 31:38 | which is not uh drapes Used the set here notice when you offer about |
|
| 31:48 | process just as we were included in cases. So what we're looking at |
|
| 32:01 | not just my F. One but on a macro like a point ball |
|
| 32:11 | now these this is the absolute Is that hard vibrate? Well so |
|
| 32:19 | we see it in the meander Okay so as we look at that |
|
| 32:28 | E. Andrews uh huh. As get closer and closer to that title |
|
| 32:36 | they begin to get a backwater begin get slack water and mud deposited during |
|
| 32:45 | flooded it. And not just during flood events but also during the title |
|
| 32:52 | . Mhm. Now I think I this last time I didn't uh It's |
|
| 33:03 | your first impression is followed this herringbone track Because you've got 10 seconds |
|
| 33:11 | The problem is you've got this so can fight rapes. Someone takes luck |
|
| 33:24 | preservation potential of those rapes and the part of doing this high quality, |
|
| 33:32 | this tells me is this is not diagonal or semi first Because this is |
|
| 33:42 | sort of it another flight. Uh . Another when I say fun, |
|
| 33:48 | I'm really saying is a flood Yeah, basically what the title right |
|
| 33:59 | having your ribs you get smuggled. so what we're looking at in this |
|
| 34:11 | from down here to at least here maybe to here is a period of |
|
| 34:26 | tied to the left and dominant So what this means is this particular |
|
| 34:34 | was dominant for wild and flood on because remember when we've got to have |
|
| 34:42 | water coming back as came in. what happens in title settings is that |
|
| 34:51 | areas on flood dominant? Some areas hip hop and they can migrate and |
|
| 34:57 | can move the chain. So that's you're seeing here. Not a simple |
|
| 35:04 | . Company on that. Can you from what you say is an |
|
| 35:17 | You have to know something about harry . Okay. Yeah. Okay. |
|
| 35:26 | here are some larger inclined and realistic And these are all migrating $40. |
|
| 35:36 | is no longer a force it but this is a varsity. Okay now |
|
| 35:46 | we go to the North sea, of this one was greatly uh you |
|
| 35:53 | a rather consistent strike with the longshore in coastal deposition. If we go |
|
| 36:03 | here generals, you got a barrier as we continue to move down towards |
|
| 36:16 | , twitter uh into this area here barrier islands are getting shorter and shorter |
|
| 36:23 | the this spirit. How's it going the opposite direction and pick up |
|
| 36:30 | So what we're doing is we are at a zone where me shell basically |
|
| 36:41 | wider. Why? Because it's fun shape. So those time and ways |
|
| 36:50 | are being brought in are basically converging ample. So we're looking at title |
|
| 36:57 | inch. This occurs. I was baby dogs. Example what? Uh |
|
| 37:06 | they these three shape rent being identification into the macintosh. All |
|
| 37:18 | converse the effective ways left and part it is because relationship between waivers |
|
| 37:31 | So by definition is tied, flies but also the type of man you |
|
| 37:38 | gave the best because of wave attenuation we are sure. So the combination |
|
| 37:48 | the liberation of the way gives you change waved on the coastal city so |
|
| 37:58 | six. And with that linear for farmers for a wide angle section versus |
|
| 38:14 | . They need a very true. let's look at one area that you |
|
| 38:24 | is jade bay. And here we a typical title. Flat fishing. |
|
| 38:33 | got four cents metal bloody saying next they're finding it up. This film |
|
| 38:43 | tend to get most of our federal . Okay so here's our sand |
|
| 38:49 | But what and what this is basically lot of types of deregulation that you |
|
| 38:58 | and the intensity intensity Almost 100%. was blood flat. The video one |
|
| 39:11 | the characteristic. Uh huh. Oh face. She's uh this case organisms |
|
| 39:21 | is very little. And Aaron Nicola a huge shape. And this is |
|
| 39:31 | she looks like. So this type shaped burrow uh is characteristic of the |
|
| 39:40 | of middle to lower santa. But a lot of uh ignore fishies trace |
|
| 39:46 | species. Get in here. I'm not. You're getting into. |
|
| 39:52 | So here is a typical face. trapped. And here is heard smart |
|
| 40:00 | first section redressing programming time with the flat. Over lane nick Sandmann. |
|
| 40:14 | in this particular what we see here moment and it's more of a sand |
|
| 40:23 | ? Higher energy wanted my time are getting warmer shelves public uh place your |
|
| 40:36 | and we're gonna get it right. is up in that section. |
|
| 40:50 | Now if the significance of this it's really pretty because this is a |
|
| 41:00 | is considered uh a pair of So we actually get transgressions and regressions |
|
| 41:09 | Fucks. Not particularly surprised, but had it here. So one of |
|
| 41:17 | ideas recently was this is attending the range. So we could look at |
|
| 41:24 | title Pleurisy in the tournament. The the highest to the lowest sandy |
|
| 41:34 | That's the time. Okay. turns out that's probably not the |
|
| 41:41 | Yes. Oh, and and that's we get entirely one day at |
|
| 41:48 | So all the time in title sand in history because is adjacent to |
|
| 41:57 | Uh so where we draw the line is actually have a heart and he |
|
| 42:07 | that he still be constructive vertical as chicken of a pro grading title |
|
| 42:15 | And we can also see that we can have their people this regressive |
|
| 42:27 | sketches. That's what you want because can people higher up. So this |
|
| 42:34 | what the vertical sequence of a title that looks like in the absence of |
|
| 42:40 | chips. Mhm Yeah. And here the types of bedding particular navy fraser |
|
| 42:52 | And that's just exactly. So do have at least this diagram here, |
|
| 43:00 | there any news? Is that one ? Just Oh yeah, okay. |
|
| 43:13 | right. So I want you get sense of that vertical sequence in |
|
| 43:19 | E the change from santa and the in the nature of that. Now |
|
| 43:30 | problem comes when we begin to look higher class and you realize that they're |
|
| 43:35 | always flat, there's a lot of title channels, Some of those channels |
|
| 43:42 | pretty big and so there clearly must another part to this face. She's |
|
| 43:49 | . Yeah. And that is the checks. Uh here uh 5 50 |
|
| 44:03 | , I don't remember, but if addressed it, it might look something |
|
| 44:07 | this, Where you're going to be like this is analogous to a 5th |
|
| 44:19 | . And this is the point bar find analytic strata, sandbox, |
|
| 44:31 | Sometimes it's appreciated what we have Here we have that uh uh plants |
|
| 44:40 | is loaded into by that I would Now this is a little time. |
|
| 44:49 | tend to start up near the upper of the middle apartment of the, |
|
| 44:55 | like that kind of kid Wieters, literally draining it by setting the |
|
| 45:04 | but okay, here's another example of . You have a car and here's |
|
| 45:16 | I want would look like as it exposed in the record and overlay and |
|
| 45:24 | Not Fox. Okay, two, gonna 57 scale. I'm in a |
|
| 45:37 | is your title problem. Part of chain migration right now when you look |
|
| 45:45 | these better than Kyle point bars in little bigger picture, particularly the |
|
| 45:52 | uh, even something smaller. The here is not so you might have |
|
| 46:03 | uh, my period but look at the fitness okay. Of the point |
|
| 46:15 | . They're actually getting bigger and bigger conversely assault. Just getting point |
|
| 46:25 | It's the direction to compensate what this is basically the science is going |
|
| 46:35 | Yeah, a lot of success. ? So these bars provide great exploring |
|
| 46:45 | there can be a outside chance Yeah. Uh huh That we |
|
| 46:52 | we don't get this straight talk you buy think of maybe more typical of |
|
| 47:01 | fluid. So one of the things suggested as a possible study topic is |
|
| 47:10 | compare a title point bar. Now , here is ratings. Yeah. |
|
| 47:26 | you're looking at some photography within eroding fulfilled to this point here and then |
|
| 47:39 | world changes right here. Maybe Okay. What we're looking at is |
|
| 47:45 | base of the large estuary. Yeah. The areas below here are |
|
| 47:57 | burrows within the underlying substrates. Uh, they are in fact some |
|
| 48:03 | of crap and notice that you get up those boroughs fill with this claim |
|
| 48:13 | . Shell material. And so what looking at here is the face of |
|
| 48:20 | major chance. The channel lag if look okay. And one of the |
|
| 48:30 | you see have all kinds of compacted creation. Wow. The fact that |
|
| 48:39 | shells are up, his evidence that been cultivated as opposed to positive high |
|
| 48:50 | for example, content down indicated with truck. So this area has been |
|
| 48:59 | bottom of big chance. Yeah. again, uh you see such as |
|
| 49:08 | . Yeah. Right. This is channel black. Now we get tidal |
|
| 49:20 | in a variety of time ranges. in some cases this is an example |
|
| 49:27 | a hyper title. Uh huh. nine ft 9 m. Uh |
|
| 49:39 | This is uh Korea but in many in many ways this is similar to |
|
| 49:46 | we described in smaller title ranges in . The lower part is a sand |
|
| 49:54 | , it's got large dunes. The flat and I put this in just |
|
| 50:03 | shut that. These are usual places I had to work with some of |
|
| 50:10 | class. Yeah. Trust Sanders. I admire anybody is going to |
|
| 50:20 | Okay. So basically these guys were measurements and their migration of these by |
|
| 50:36 | three D and fall. They actually at it Uh over a period of |
|
| 50:48 | years. So they look like and migration. Yeah. What they found |
|
| 51:04 | that they were up changes that were to not only just spring and neat |
|
| 51:15 | but also between rain intensity and more in the summer he had some among |
|
| 51:29 | . And so in this area there tense ranger. It's something. So |
|
| 51:33 | going to be erosion and no time pictures said particularly much mm now in |
|
| 51:47 | fall and winter where you didn't have blessed already corroborating confrontation. So the |
|
| 52:04 | of this particular area is mainly due the seasonal changes in rainfall and less |
|
| 52:13 | to alternating tires, even spring meat no salt. So when we look |
|
| 52:25 | yeah, those no, it's just sense oh, you got title framework |
|
| 52:38 | also we have to look at the when, when you, when you |
|
| 52:42 | at uh, will evolve pay for examples family. I should say when |
|
| 52:51 | actually try to interpret minute, particularly respect to channels, you're not looking |
|
| 52:59 | , see that at daily variations. not looking at rhythms most internally hit |
|
| 53:08 | for inclined naturalistic stratum are actually doing term changes could be summer, winter |
|
| 53:17 | be something it's only in the title , especially the upper part of the |
|
| 53:24 | that we have the possibility of something enough will not have a lot of |
|
| 53:30 | brochure and also enough deposition with time give you literally daily. Uh, |
|
| 53:43 | is another study. Upper vibrating lower channels. Sam same as |
|
| 53:52 | That really matter with recent. It to get sense of the range here |
|
| 54:00 | basically sandy. So Oprah contrary requirements to inter bedded mixed sand, but |
|
| 54:11 | things will not change some of these . They really sound of this is |
|
| 54:22 | cross section. It's actually yeah, else some place. Uh It's either |
|
| 54:32 | or Korea again. Yeah. Right if we look at this particular example |
|
| 54:43 | we talked about uh It's again this example. Tyler harsh. I activated |
|
| 54:54 | mixed with former senator but then you a look at and I don't want |
|
| 55:03 | . Yes. Uh huh. The I would say 50 for this variation |
|
| 55:12 | style bars or praying stimulus. I know how generalized that is put into |
|
| 55:20 | . But what I want to focus not an operation is vertical section. |
|
| 55:27 | is going to be different perception So let's just go right next to |
|
| 55:35 | . This is actually behind the third life. So it's going to be |
|
| 55:40 | mixed setting. And if you look maps for 70-year period you can actually |
|
| 55:49 | how much of that area has been by chance and it's something. My |
|
| 56:00 | . Okay. What? This is the depth of the world. So |
|
| 56:06 | of this topic has been reworked to extent. Right? Uh huh. |
|
| 56:14 | ship sir? No. Which means this much of the area is here |
|
| 56:23 | consist of channels that are consistent channelled to inter chin top flats. So |
|
| 56:34 | might look something like this. Here's samples notice that extends belong. |
|
| 56:45 | In the upper skip this for a . So that is the vertical secrets |
|
| 56:54 | expect in the absence notice. So is a channel. Okay. Yeah |
|
| 57:02 | send filled this case. Next wire of it extending all the way down |
|
| 57:12 | there. They can blow which is lot of the mixed let deposit some |
|
| 57:26 | the lower art astra chip. So get a lot of scouring till we |
|
| 57:37 | a lot of right. Yes lateral , ones vertical creation. So here |
|
| 57:52 | got kind of an example before we basically most of this is vertical lateral |
|
| 58:02 | and some of this it's a lot this so has been reworked by laterally |
|
| 58:12 | cops. So if we are looking that title flat package uh it's going |
|
| 58:23 | be this vertical city. You know fashion here. Yeah. Well |
|
| 58:39 | And uh huh. We've got adequate . Mhm. Cutting into whatever we |
|
| 58:54 | here is your bedding taking monsters. then we had this larger time next |
|
| 59:05 | significantly talk and can be getting some good uh dunes it said so fairly |
|
| 59:19 | . Cut it off laterally meandering. pretty much our model. True. |
|
| 59:31 | not all tidal flats are in the uh right imprint protective in history. |
|
| 59:41 | are open to the marine environment and this particular example. Look at negative |
|
| 59:51 | and referred titles last setting. Except we have high wave energy cause we |
|
| 60:00 | more and more exposure to. Seems an optima Ron. This is |
|
| 60:04 | of those cases where we have highways ties. Yeah the title affects are |
|
| 60:11 | dominated. A higher arts. Wait, more complicated in Burundi. |
|
| 60:27 | we have is a patient. He had quality pasta that we're getting smaller |
|
| 60:42 | title cross stratification. That would be waiting, waiting. So this four |
|
| 60:57 | association for I'm not insane. Were part one get a look at the |
|
| 61:15 | . What? Yeah, somewhat similar . It should here we know from |
|
| 61:31 | high. Wait, my flat you know, it's the same support |
|
| 61:43 | sheet front the grades offshore into. was saying bridges now this part up |
|
| 61:52 | we're pretty similiar. Pretty much what describe. Uh Yeah, saturday night |
|
| 62:06 | including some of the channels. But then we get in and shoot |
|
| 62:14 | and uh there is going to be lot of mixed way entire influence. |
|
| 62:23 | a minister very. Mhm. Little . two more models with the I |
|
| 62:36 | who need deeper water. Finally into linear title sandwich. We're gonna talk |
|
| 62:44 | about this. Uh when you talk thai dominated the history of this. |
|
| 62:56 | in general, what they do tend migrate. Michael here, New Orleans |
|
| 63:08 | selected even though better elongated parallels of parables child. Uh the chance to |
|
| 63:17 | dominant win my great because of the and either the flood or and if |
|
| 63:29 | have time talk more about this the day. And I suggest you think |
|
| 63:38 | how you might distinguish that from a change it. And your first thought |
|
| 63:46 | the old scape. Okay. And thing is, some of the the |
|
| 63:55 | induced shelf deposits are to scale comparable the only do. Yeah. |
|
| 64:05 | And then eventually, so here's what get as you know on shore, |
|
| 64:18 | get onshore titles left right, have on top of each other to imagine |
|
| 64:27 | you get with that program. this we gotta gotta mentioned some different |
|
| 64:38 | . No, someday I never had in the summary of course leave that |
|
| 64:48 | you to think about. Uh I this here because this is one of |
|
| 64:56 | reservoirs which are in the subtitle. huh. High energy Tommy ability is |
|
| 65:12 | great as we get further down, away from the thick mud grapes. |
|
| 65:23 | get a little more horizontal community And it turns out that about 30% |
|
| 65:30 | videos. Current oil production is from highly influenced reservoirs, right? |
|
| 65:43 | Okay. Um because you all need little extra credit. Uh I'm gonna |
|
| 65:48 | you a five minute pop quiz. do we mean by intersection on your |
|
| 65:57 | ? Yeah, she is really care topic. It was a short break |
|
| 66:13 | I'll start. Did not finish uh to reach me. |
