Her scenario assumes the sediment was all present when the water begins recession. Not necessarily, I try to avoid making such assumptions.
I can see this type of sequence developing as the ocean levels fall. That has occurred to me. I don't feel a need to establish a perfect model for the Flood's deposition. Walther's Law seems to provide enough of a general model, what would be the point in trying to be exact about something there's no way to be exact about, at least in the early stages of the discussion and when there are lots of other questions to deal with as well?

Your posts have been heavy with jargon lately, HBD, if you want a reason why I generally don't respond to them. In this case I have to ask what is an "energy gradient?"

The deposition of any of those sediments doesn't necessarily take time although their formation may, and even there probably nowhere near as long as OE thinking assumes. Beach sand is not created on the beach, it's created by tossing in the water and then it's deposited on the beach. Edited by Faith, : No reason given. Edited by Faith, : No reason given.

I know you put that up to demonstrate that there must have been a variety of depositional environments with all that moving around the globe, and I suppose if we're to take that animation seriously that must be true.
But I got more interested in how there's a lot of tectonic bashing going on there. Silurian, Devonian, Carboniferous particularly. And when it's not bashing it seems to be twisting and pulling and distorting a lot. Makes one wonder how any of the layers of the Geologic Column managed to survive intact at all. Just to consider the bashing wouldn't you expect the strata from the Silurian to the Carboniferous to look very much bashed around, say in the Grand Canyon? Or anywhere else of course, it's just that the GC displays the strata so well. But that block of strata doesn't look any more bashed than any of the rest of them.

Thank you, that was very helpful. You actually explained WHY the sediments sort in the order they do.

Not sure what you are saying. I know it represents a painfully slow movement in reality, but the whole idea of tectonic effects, such as in the raising of mountains, is based on these movements, and speed doesn't seem to be a factor.
ABE: Obviously I'm still thinking about the bashing but never mind, I get that you're talking about compressing all that into the time since the Flood. But I don't. I've watched lots of these animations and many of them start just before the Atlantic ridge forms and separates the Americas from Europe and Africa. That's the movement I generally have in mind and the rest of it in this particular video seems made up to me. Edited by Faith, : No reason given. Edited by Faith, : No reason given.

Thinking more about Walther's Law, not clear how the sediments deposit. As the water rises onto the land are the sediments precipitating out or what?
Also it seems they are all being deposited at the same time in their respective locations -- sand, mud, silt, carbonates, foram ooze -- rather than sequentially. At least the horizontal sequence is. Is this correct? This being the case how do we get different depositional environments? And if this model does apply to the Geological Column, how do we get the great separation in age from one sediment to another? I realize this has to have something to do with the difference between the lateral deposition and the vertical that develops as the sea level rises but I can't figure it out. RAZD's Message 39 is very helpful for picturing the model in relation to the Grand Canyon sequence of rocks, but I'm unable to see how we get different time periods from this model.

Seems to me that gnudging should have had more effects on the strata of the Silurian/Devonian/Carboniferous level than seems to be the case in the GC area at least, and I don't know why that area should be an exception when you've got continents gnudging each other.

Since you don't believe in the Flood you don't have to make it fit what we see today, you can just pronounce it impossible and forget about it. But obviously I can't stop where you stop. And besides I think my scenario is more feasible than yours. No way to test it, is there? Edited by Faith, : No reason given.

Right, that's why the layers are different. Different environments. Got to pondering this point again. Wonder if those who determine the depositional environments from the rocks, and those who made the animation of the movements of the continents, got their information coordinated. If we find out where, say, the GC was on that animation would it correspond to the kind of environment determined for the rock in that era? Or might it for instance possibly be located near the North Pole when the rock information says Tropical Sea? I kind of have a suspicion there will be discrepancies but maybe I'm wrong and they did do all the work of coordinating such information for the entire planet for all those supposed past eras. Just a thought.

I haven’t researched it, but to me bedrock is more of an engineering term, something solid enough to build something heavy on. A term you hear more in geology is basement rock": OK, but it's nice if I'm going to be wrong to be wrong along with roxrkool, who wouldn't get reprimanded by edge.
rocks below a sedimentary platform or cover, or more generally any rock below sedimentary rocks or sedimentary basins that are metamorphic or igneous in origin. OK, though I have a feeling if I used "basement rock" he'd object to that too, even if it's correct. I think I'll go with your original "solid rock." That's probably not safe either but at least it doesn't suggest something technical.
Edge and roxrkool are experienced working geologist. I’m a much less experienced, not working geologist. I know, but you do know a lot and you're a nice guy which is even better.
But I don't see the huge rivers you see. More likely thousands of small rivers or rivulets flowing off hills in a sea of mud that slides down in masses and sheets. So I don't see the delta buildup you see, or the formation of river valleys.
I didn’t mention the upstream flow, but that is what would get the sediment down to the large rivers. It is really speculation, of what the water/sediment load ratio would be. I was visualizing more towards the water carrying a lot of sediment, but I’m sure that in at least some situations it would be flat out mud flow. Either would get the sediment moving down gradient, but I see the less dense and viscous flow as moving all the sediment better. The denser and viscous mud flow would leave more lag deposits behind, especially in lower gradient (less steep) areas. In other words, where things got less steep, the mud would pile up. But while the solids would stop, some of the water would continue moving. And remember, it’s raining really hard everywhere, so more water is always being added. Right. There is no way to be sure of any of this as you say, but I think we'd have mud soup more than anything as solid as loose mud very early on myself. I just don't see big rivers BECAUSE it's going on raining very hard everywhere, not just in the higher areas, and it's all running off the higher areas willy-nilly, most of it mudslides. I suppose small streams would run into big streams here and there but I can't see anything that organized remaining for long BECAUSE it keeps going on raining everywhere and breaking up everything, any river banks trying to form would be eroded away in the overflow before they could even get formed. It's all speculation though.
Soon rising sea and soaked sediments meet and mingle in a thick soup over the denuded bedrock. This is the ocean so we have tides and waves and currents to move things around.
Now you’re (more or less) talking waves reworking a mass of sediments with grain sizes ranging from clay to boulders. The boulders would stay in place, and the finer sediments would disperse, the gravels close, the sand further away, the silt further away, and the clays even further away. You’d have the distribution shown in the various Walther’s Law diagrams that have been posted. But you’re not going to get limestone, which is of biogenic origin. OK to most of that but not sure why not limestone. If it's deposited anywhere according to the Walther's model, being present in the sea water, it should be present in THIS sea water too and deposit in its turn along with all the other sediments.
Here's where I figure Walther's Law might enter, as the water is rising over the land, starting the process of building up strata on the naked bedrock according to those sorting principles. That process could start later though, not sure what all has to be taken into account.
Basically correct. But Walther’s Law isn’t really that of a sorting process. It’s a geometric description of what you get when depositional environments shift. Which I guess is sort of splitting hairs. Afraid "sorting process" is clearer to me than "what you get when depositional environments shift" though I'd be happy to use that description if I could understand it. Anyway, thanks for being a big enough guy to say that Faith could ever get anything "basically correct."
One way or the other the sediments are redeposited on the land mass in layers by the end of the Flood Three miles deep at least. So when the water recedes and erodes some of it away there's so much of it, and it's already so compacted in the lower layers, the erosion is far from scouring it down to bedrock again.
But I think that the reworks sediments would form a relatively thin veneer on top of a much thicker heterogeneous clay/silt/sand/gravel/boulder horizon. This I don't get. If the sea water creates layers then it should layer all this too.
And we don’t have enough sediment available to be eroded (my the way things are today scenario) to form widespread miles thick layers. But the way things are today IS that we have extremely thick deposits of strata in many places and the clear indication that those existed in other places too but were eroded down to much less. Some of the strata span entire continents in very thick slabs. I don't get what you mean about not having enough. And we don't know how much sediment made up the original land mass, all we can do is extrapolate from what we have now anyway. If a depth of three miles of strata were originally laid down on the rock base of the continents, and a great deal of that washed into the sea, that should be enough sediment for my scenario.
Besides, you’d only get a single transgressive/regressive sequence, not the multiple that we can see in the geologic records (geologic column). OK. That's something ponder. If the multiple is correctly interpreted.
And you wouldn’t get limestones or other biogenic deposits. And there’s always the problem of all the deposits that are not of marine origin, mixed in there in your geologic column. Again I don't get why not limestone since it normally gets laid down as part of the Walther's sequence simply because it's in the oceans. The Flood would have been the rising of the ocean all over the planet, carrying a lot of marine material of course, but now also carrying the land sediments and creatures. Waves, tides and currents have to be involved in the great distances over which they get distributed too. I don't see why we WOULDN'T get what we see now in the Geologic Column because both should have been abundant in the Flood waters. I know you're the geologically educated one but nobody has seen a worldwide Flood, no creationists, no geologists, nobody, and what we see now WOULD have been the result of such an event if it had occurred.
Since you don't believe in the Flood you don't have to make it fit what we see today, you can just pronounce it impossible and forget about it.
We just created a what the results of the flood would be scenario. And it doesn’t match up with what we actually see. This is part of why we say The Flood never happened. And you all created this same sort of scenario on that old thread you linked too, which was fun to read because it's all exactly the same sort of speculation creationists do, though of course we're going to speculate in the direction of explaining "what we actually see" by it and you aren't. Your speculations don't match up with what we actually see, but creationists' do. As long as it's all speculation, which it is, I don't see that yours have a better claim than ours.
But obviously I can't stop where you stop. And besides I think my scenario is more feasible than yours.
You are not troubled by the fact that your feasibility scenario totally clashes with those of people who have done a lot of schooling and field work, studying geologic processes and their results? I'd be a lot more troubled by any scenario that clashes with what God has revealed than anything that clashes with what mere human beings come up with, no matter how educated or sincere. I see the Bible as giving at least the outline of a worldwide Flood within the last ten thousand years and the attempts others have made to conform the Bible to what geologists have come up with just don't convince me, I worry for those who would do that as a matter of fact. So no, I'm not troubled by contradicting geologists. I'd rather not, of course, it's not fun being at odds with those who do this work, but I don't see that I have any choice. And as along as I'm able to visualize anything that is in the ballpark of supporting the Biblical record without outright contradicting physical laws it's both interesting and fun to do despite all the opprobrium that piles up on my head for it.
That’s kind of like if I (geologist) went a told a renowned brain surgeon that he didn’t know what he was doing. Not really. The surgeon isn't contradicting God's revelation, nor is any science other than where they insist on an Old Earth and Evolution. And again these are of course the sciences of the prehistoric past, as I keep emphasizing, the ONLY sciences that have little more than speculation to build on. "Little more" i say because there are some things you can prove, just not the essential things, and so many keep trying to prove they are just as testable and provable as the "hard" sciences, but they aren't. That's why we're getting so involved in these posts in constructing speculative scenarios that we can't prove but hope are plausible. That leaves a lot of science that God has no problem with.
No way to test it, is there?
A lot of processes can be seen out in the field, and be modeled in the lab, even if we can’t perform an experiment on the world wide scale. Modeling the Flood in the lab would be an impossible undertaking. I'm sure certain features of it can be modeled but I wouldn't know where to begin. Edited by Faith, : No reason given.

I don't know if you're right or not of course, but thanks for understanding what I said. It's SO nice to be understood even if disagreed with. Not that I'm disagreeing in this case, I really don't know if the different sets of data have been coordinated.

Do you ever have suspicions that your interpretation of the Bible is incorrect? Nope, not after a couple decades of reading and hearing the best exegetes thereof, those who are led by God, which a believer CAN usually tell.

Sorry, the rocks do not speak and everything said about them is the work of fallible human minds. That is why God gave us a written revelation, because we DON'T know how to interpret nature. He's in it for sure but if you are contradicting His graciously given written word then you are wrong about what it means.

I wanted to emphasize this point. We can be pretty certain that the Indian subcontinent is colliding with Asia because of actual measurements. For Faith, this is called 'evidence'. We know what is happening right now to a certainty. Now, by comparison with older mountains, we can create hypotheses ... and they are supported by (drum aroll) ... the evidence. Sometimes you are talking about real evidence, and it's the same evidence creationists make use of too. But sometimes you are just reciting the Creed or invoking "Evidence" as a dogma, though not really giving such evidence. I am sure the Himalayas are being raised by tectonic force even as we speak.
