We are in one of those phases where nothing you say makes any sense to me and you blame that on my being a YEC and that's really the end of the possibility of discussion.
If you say so.
Again I don't see anything in your post that shows why the water didn't need to rise miles to lay down the sediments miles deep. You assert it but don't prove it or even give a half-baked reason for it. As long as the geological column exists miles deep anywhere on the continent it could only have been deposited by water miles deep.
Not really. The craton (the basement rock, if you will) could subside and allow more sediments to be deposited in a later event. We know that this happens, so I'm not sure what your complaint is.
The Grand Canyon for a visible instance is a mile deep; adding the strata of the Grand Staircase shows the whole column was originally two miles deep at least, and there is reason to believe there were more strata above that. Nothing you have said about basins or the craton changes this picture.
Actually, the Grand Canyon and Grand Staircase rocks were not deposited on the higher part of the craton. It actually occurs on the edge of the craton where subsidence is frequently observed.
As John Morris said in that article about the St. Peter Sandstone, that sandstone reaches across the entire continent of North America 3000 miles by 1000 miles and up to 300 feet thick. That's evidence for the Flood. There were no mountains at that time, the continent was a flat featureless plain (scoured off by the forty days and nights of rain and subsequent mudslides etc.).
There are a few problems with Morris' story. For instance, if this was a transgressive sand, that means that there was a source for the sand. That means a land mass and erosion of a quartz-rich source rock. Where do you think that was? In fact, much of North America was underwater in the Ordovician. However, Morris forgets that there are other continents and does not recognize that most of those were not inundated. Remember the differences reported by Pressie?
The Cratonic sequences would have been phases of the Flood, each laying down a thousand or more feet of strata (1250 feet in the Sauk Sequence), the unconformities that mark each phase being the effect of the erosion caused by the regressive phase (not a "missing" time period millions of years old).
Except for the obvious (to most of us) time range and the fact that the sequences do not cover entire continents or mountain belts.
Basins would not have been there originally.
Some of them perhaps. However, it isn't to difficult to tell the age of a basin from its filling material. There are modern basins, for instance that oil companies drill completely through to find pre-basin rocks as source rocks or as reservoirs. If that is the case, we would know it. I have seen the effects of salt tectonics here in Colorado. It's pretty obvious.
The fact that the Cratonic Sequences are recognizable in the basins just means the unconformities that mark them are recognizable.
That and the fact that they rocks vary laterally in many ways, including thickness and number of units. This was one of the early puzzles for geologists as to why there were some rock sequences that are so thick and why they often occur in mountain ranges.
The reasonable explanation for the whole thing is that the strata were laid across the whole continent one on top of another most likely by a rising tide, then much of it was eroded away when the tide went out.
Sure over millions of years there were many transgressions. Some major and some minor.
The water was rising all the time in the Flood.
That makes it kind of hard to explain evaporites and trace fossils, doesn't it?
The next tide/ transgression was higher and deposited another deep thickness of strata on top of the first, then regressed, eroding away much of what it had just deposited, and so on up through the six sequences. The water had to keep rising to deposit at the higher and higher levels laid down by the previous tide. (Neither craton nor basins, had they existed, would have affected this basic pattern).
So in between these 'tides', you had time for dinosaurs to populate the planet and build nests and raise young, all the while changing the community of species.
After it was all laid down the basins formed, in the case of the Michigan because of the salt layer at the bottom of it. The eroded areas called unconformities remain visible in the basin.
The problem being that the sediments are significantly thicker in the centers of the basin.
What the craton has to do with any of this completely escapes me.
I would imagine so. I mean the fact that they are called 'cratonic sequences' doesn't mean the the craton has anything to do with them, yes? (Balance of text snipped for brevity) Your little story is nice, but it is contrafactual. There is nothing to support it. I'm not going to sit here and take it apart point by point as I/we have in the past. You can believe what you want, but it makes no sense with respect to the data in the field. You are alone on this.

Edge hasn't responded yet and will have to confirm, but when you say this:
How this could have happened after deposition of strata across a continent is not clear. I would ask Faith how that might have happened.quote: As I said, Edge will have to confirm, but I believe he's agreeing that miles-thick sedimentary deposits are possible from a shallow sea. That's how the Michigan Basin formed. Here's that image again. Note that the depth of sediments grows to over a couple miles, and the water depth was never near that great. It was a shallow sea, the lowest point in the region, and it accumulated sediments over time that with the weight of increasing thickness gradually subsided into the continent In answer to your suggestion, yes, I believe it can and does happen. When you look at the depth of sediments in the Mississippi Delta, you have to ask how 15km of Tertiary sediment can fit into a body of water only 4km deep, at the most. This stuff has to be sinking into the asthenosphere. Right now.

I believe I already explained what would have to happen for the water not to have to rise miles to cover miles of sediment in Message 514. Each deposit sinks so that the next can be deposited in shallow water. That explanation seems to cover it.
And that explanation has been refuted. But basically yes a portion of the cration subsides under the weight of new sediment. You know, it wonders me that YECs can easily accept that water will displace the asthenosphere to form the ocean basins, but cannot accept that sediments are actually shown to do so.
Since there are extremely deep areas of the Geological Column, flat across the country, and some of it DOES extend into the UK and Europe, as Morris says, those parts had to all sink together.
Very possible. At the particular time of the Saint Peter sandstone both the North American continent and Eurasia were not undergoing mountain building, so the were at a relatively low elevation, so yeah, they had a similar history. That changed in the late Ordovician.
A basin explains absolutely nothing about that. And as evidence it's useless. You need evidence for the large flat areas and so far I haven't seen any. But hey maybe I missed it. If so I'll come back to it eventually. Yes, I don't get what the cratons have to do with any of it since presumably the sequences covered the entire continent.
No. That has never been stated. I went out of may way to explain this part of the story.
I've had enough. Communication with you is impossible. I'm not interested in your little snarky remarks or any of the rest of it. Far as I can see the Flood explains it all just fine.
And I'm not thrilled with you calling my arguments fraudulent. So we are even.
And Pressie's volcanoes won't fit in the Jurassic strata. You might tell him that.
As I have said repeatedly, the craton does not necessarily include the continental margins where volcanoes and mountain occur. The cratonic sequences only explain the inter-regional transgressions across certain northern continents. And I'm sorry, but if there are volcanic rocks in the Jurassic, they HAVE to fit in somehow.

Volcanic rocks in Jurassic strata is qujite possible. Volcanoes are not.
I thought this thread was done, but this statement is puzzling. How do you get volcanic rocks without volcanoes of some sort?

The same way you get dead dinosaurs or dead trilobites in various strata. They were carried in the Flood and deposited in that particular layer.
Perhaps then you have evidence that intact lava flows were transported over long distances to their present locations in the strata. Perhaps you have some idea how certain volcanic structures such as calderas and volcanic vents were preserved during transport to the Jurassic System.
It's not a time period.
Whatever you say, Faith.
The fact that it's a flat slab of rock found among other flat slabs of rock all over the world is the proof that it's not a time period, it's a slab of rock that was originally a layer of wet sediment laid down in the Flood. A volcano won't fit there.
Except where they do fit in. And, perhaps to you, it's just a 'flat slab of rocks', but the observations say differently. There are processes, compositions and textures that have meaning.
Yeah this thread is done, I just had some mopping-up thoughts.
Yeah, there could be a lot to mop up if one is interested. And just to amplify on an idea that came up earlier about compaction, here is an image of a section through the Hermit/Coconino contact showing mudcracks in the red Hermit Shale filled by sand from the overlying Coconino Sandstone. I've been looking for this image for days now.
Notice the 'lightning bolt' shape of the cracks as they were compressed by the weight of overlying sediments. Notice also the wavy nature of the contact as there were slight variations in pressure exerted on the underlying shale. And here is another item that I thought might be of interest to some before the thread dies. This is a schematic of how many lithological contacts occur. While the differing compositions are clear, it is not clear where to draw the contact as it would appear on a map. Would it be at the first shale or at the last sandstone layer?
The reason I bring this up is because of all the talk about knife sharp contacts that we have seen. The reality is that contacts are not always clear cut.

Isn't it dike, not dyke?
Spelling in the English language is not uniform over the world.
Anyway so you have a dike called Jurassic that penetrated into a bunch of rocks called Triassic. So? Come to think of it how is that possible since the Jurassic followed the Triassic?
I guess you are not familiar with the concept of cross-cutting structures... The point is that if a dike cuts across a rock (Triassic in this case), it is younger than that rock. If it does not cross-cut another rock (Jurassic in this example) then it is older than that rock. So, the dike had to form sometime between the older and younger rock. Okay, so if you can find a place where the dike cuts across all sedimentary rocks to the most recent 'flood' rocks, then you could say that it is younger than all of them.

Now, of course, you aren't just talking about some volcanic rocks, you are talking about lava flows which is something else. My guess would be that they are sills that pushed into the Jurassic strata at the end of the Flood, but just a guess of course.
An uninformed guess, of course. Do you really think that we cannot tell sills from flows?
There's evidence of post-Flood volcanoes, in the Grand Canyon, Grand Staircase area in particular, which was part of earlier arguments on this subject.
Of course there are volcanic flows and volcanoes of different ages.
And I'm sure you will agree that whether or not I can offer the evidence you want proves nothing about the Flood.
Yes, I would say that your arguments are irrelevant. Primarily because you have no knowledge or experience.
Which is nowhere in a flat slab of rock.
Considering that it is not a slab, nor a flat slap of 'rock', your post is meaningless.
With about the same degree of objective value as reading tea leaves. The human mind is marvelous when it comes to putting together disparate objects to create meaning.
In your case a wrong meaning.
A fossilized bone buried in a slab of rock among fossilized plants becomes evidence of a creature that roamed around in a world that contained those plants instead of evidence of a dead animal and dead plants buried in mud. Ripples caused by wind on a still-wet deposit of the Flood become a beach. Marvelous imagination.
Sure. We should just ignore the evidence left behind in the rock record. What a dreary, intellectually vacuous life you must lead.
My attention span isn't too good at the moment.
At the moment?

As I recall, a British team of creationists were studying just this phenomenon a few years ago. I forget their purpose, something to do with earthquakes as I vaguely recall, ...
Well, as I recall, they had to reach pretty far up into dark places to come to that conclusion. Anything to maintain that tiny little doubt in your mind, eh?
... but all such communications between "time periods" are much better evidence for the Flood.
Just another baseless assertion ...
But in any case if you are implying that I say that the contacts between layers are ALWAYS tight, you're wrong. Just that their existence at all is evidence against time periods and for the Flood.
So, how many 'non-tight' contacts do you need to contradict your preconceived notion?
The very existence of such a contact that intersperses the sediments of different "time periods' is evidence against them. Tight contacts, muddy eroded contacts, interspersed sedimentary layered contacts -- none of it is evidence for time periods, but good for the Flood.
Another baseless assertion. I am not talking about time periods, I'm talking about transitional contacts between lithologies. It appears that tight contacts or transitional contacts, or any contact at all is 'evidence for the flood'.

It's a little ambiguous which parts of the explanation have been refuted. If it includes the "Each deposit sinks so that the next can be deposited in shallow water" portion then I think some additional explanation could be helpful.
Frankly, I'm not sure what Faith was trying to say here. It sounds like Faith was agreeing, but that couldn't be the case.

Yes but the Jurassic comes after the Triassic, and this appears to penetrate from the bottom up through the Triassic; isn't that the wrong order? How did the Jurassic get beneath the Triassic?
Pressie's first image is of Jurassic aged basalt flows, while the second one is a basaltic dike thought to be the intrusive source of those flows. The dike cuts through the older rocks to reach the surface and form the lava flows.
This ought to be fairly simple so I don't know what I'm missing. The GC examples I mentioned penetrate from beneath the canyon area all the way up through the uppermost level of the Grand Staircase on the north and the canyon on the south, so the volcanoes were clearly younger than all of it.
Some volcanoes, sure. Others are clearly older and do not penetrate the entire section.
That's clear, but the current example is hard to interpret for some reason since the Jurassic should be above the Triassic yet pushes up through the Triassic from below.
That is because the volcanic rock is partly intrusive and partly extrusive. While it was still magma, the basalt flowed upward through cracks in the Triassic rocks and then erupted onto the surface.
How does a volcano originate in a layer of sediment?
It doesn't. It originates in the lower crust and then migrates upward. Sometimes it reaches the surface and sometimes it doesn't.

You know we all think that's wrong, yes?
Except for the fact that it shows no flood.

Faith will have to confirm, but I think her scenario was that each tide left behind sedimentary deposits that due to weight subsided downward, then the next tide would come in and the process would repeat.
It's a strange tide the brings in coarse sediments from the sea. It's also a strange tide that happens only six times in a year. It's a very strange tide that deposits limestone.
I think there is agreement about sedimentary layers subsiding.
Only that it happens. There is complete disagreement how it happens and how much land is covered and how sediment is transported. And that's just a start.
What needs to be understood is why Faith doesn't accept subsidence in the context of the Michigan basin that formed through subsidence of accumulating sedimentary layers beneath a shallow sea:
Or the fact that there are edges to the basin and sediments eroding into the basin. Or the fact that this surge seems only to apply to certain continents and that there were other land masses with mountains and erosion at the time. Basically, Faith requires (and so does faith, by the way) a bunch of ad hoc explanations that get in the way of other facts.

Waves would erase tracks on a beach soon after they were created, ,,,
You do realize that this would describe erosion which, IIRC, you reject as occurring in places like the Grand Canyon Paleozoic sequence, right?
... but there wouldn't have been waves if the Flood built up tide by tide.
Why not? Please explain. You seem to be describing a pond.
The tide would come far up on to the land, and withdraw just as far back to the current level of the sea, eroding away a lot of what it just deposited, leaving the land damp with twelve hours to sit and dry some.
And during those 12 hours, dinosaur would rush out into the flats and make nests, lay eggs, raise their young and eat exactly what? You realize that your tide is moving hundreds of kilometers, if not thousands, with each cycle.
This would be the case during the rising phase of the Flood. Once it covered all the land of course this wouldn't be happening any more.
Problem being that there is no evidence this ever happened. The presence of a beach sand imply that there was land. The presence of fossil trees implies forests. The presence of dinosaur nests, raindrop impressions and myriad other trace fossils implies land. The kind of deposition you talk about would reasonably cause mixing of fossils. How does this explain the fossil record?
(Something similar possibly occurred during the receding phase but I'm not completely sure about that -- it seems more like a gigantic rapid draining of the water taking tons and tons of deposited sediments with it).
Then, essentially, you moved the sediments out one last time. I imagine they would be quite worn out by then. Sorry but each cycle should have similar erosional effects. IIRC, you deny that there are old canyons buried in the Paleozoic rocks. This isn't holding together.

During the Flood animals would be dying but not all dead until the full height of the Flood had been reached. If it rose tide by tide, which is my main hypothesis now, there would have been time between tides for animals to try to run away from it.
But why would they run back out on the mudflats in between floodings? Death wish?

Someone mentioned that the Grand Canyon is in a basin, or subsided or something? But the entire canyon is above sea level so if it subsided it didn't go very deep, and it's also obviously not shaped like a basin, the strata are flat, horizontal and straight - relatively so anyway for those of a perfectionistic pedantic turn of mind.
Remember the to-scale diagram that Moose presented in post 613?
{Adminnemooseus note added by edit - On May 8, 2017 I added the link to the "post 613" above. On May 6, 2017 I had redone the graphics to be sourced from the Google cached versions, as the original source was no longer functional.} The GC sedimentary rocks were deposited on the western edge of the North American continent. As such, the craton there was thinner and probably younger than more interior craton such as in Wyoming. And, due to the tectonics that we discussed before, we do not have a problem with the current elevation of the Colorado Plateau.
Basins obviously can't explain the Flood scenario I have in mind, being confined to limited local areas.
It is not the data that explains the model. The model should explain the data.
I don't have any reason to object to the interpretation of subsidence in the basins otherwise -- except that I had understood at one time that it was the salt layer that was the cause, so that gives me pause.
You can pause no more. Salt tectonics is a very unique and recognizable geological process.
The main thing is that basins don't speak to the Flood scenario, and that's why I got so angry when he first brought them up, it seemed like an intentional evasion of the scenario I was pursuing.
If it were standard process to become angry at evasions, every scientifically inclined person in the forum would be subject to cardiac arrest. The problem here is that the Michigan Basin shows some of the same transgressions as the rest of the continent. It also demonstrates subsidence to which you strenuously objected and now accept. IIRC, you even asked for examples of subsidence and I provided you with three examples. Edited by Adminnemooseus, : Added link for message 613, and also comments in red.
