The strata ON THE ISLAND PROPER, meaning resting on the straight horizontal sea level line, are all side by side from left to right, and the scale will make no difference to that fact.
Yes, it would, as I've demonstrated. But it appears the concept of different scales in the same drawing is too much for you. The island proper consists of the part above and the part below current sea level. Edited by JonF, : No reason given.

Vertical is vertical, horizontal is horizontal, scale makes no difference to these orientations.

So you don't think this particular geological column was ever stacked vertically? Wouldn't that be unusual? Like, impossible? Like never happened before ever? No, each major package was stacked vertically but there were intervening orogenies that disrupted older rocks. For instance, the pre-Devonian rocks are folded and eroded before the Old Red Sand was deposited. In fact the older rocks were the source of sediment for the Old Red. So the Grand Canyon strata were deposited continuously with no intervening disruptions like those you say interrupted the UK strata, even though it's all the same "time periods" -- with some omissions here and there. Does the time factor work out? That is, is there time for those orogenies to have grown up and been eroded down between the strata as found in the Grand Canyon just for a comparison? This is what I meant by the "contortions" the standard interpretations have to go through, but oh well. At least I see better why we can't communicate about this stuff. Even without bothering about the Flood it seems clear to me that the short pieces of strata that are tilted upward toward the mountain on the west that we see on the island proper, that were all that Smith illustrated -- that those pieces were broken off at their tops from longer lengths of strata and collapsed into their current side-by-side positions when originally they were stacked vertically, with the Cambrian on the bottom instead of to the west, and the Holocene on the top instead of to the eastern end, and that the rest of their lengths which are seen beneath the island would have been ON the island spread horizontally from left to right. That just seems apparent from the illustration itself. When all the gravels and other evidence of disturbances occurred would then be the next topic, but I think I just found out in depressing detail why we can't communicate about any of this.
The Smith diagram is a simplified stratigraphic column with little information on erosion, deformation and intrusion, other than the concession that some granites are found on the west. In other words, the E-W cross section gives you a lot more geology than the Smith modified stratigraphic column. Yes, and I would expect to think about it after I get across that the original geo column was not in the positions we see illustrated on the diagram. Edited by Faith, : No reason given.

I knew it was too much for you.
Making up some numbers, the horizontal scale is 40 miles per inch. The vertical scale is 1/2 miles per inch. The angles of the contacts between layers are not correct. They are way, way wrong. This is almost unilaterally true in geologic cross sections of broad extent. It's true in your beloved Grand Staircase cross section. People have told you this many times, including this thread. They do that to make the relationships clear.

I must have misunderstood what you said originally, but I'm still not sure. When you said "grading of sedimentary grains with coarser conglomerates at the base" I thought you meant a stratum that graded gradually from fine-grained at the top to coarse sediments at the bottom, which sounds like what would happen if very active water with a heavy sediment load suddenly became still.
This is a semantic problem due to the difference between 'graded bedding' and the engineering use of the term "graded." What we generally refer to around here is graded bedding where the grains settle according to settling velocities. In the engineering sense, it's more like sorting the grains into different groups. I think if I used the phrase 'sorted according to stream velocity' that might have made more sense to most people. But now I think you might have meant something different, but I'm not sure what. What does "grading of sedimentary grains" mean if not grading from fine to coarse with increasing depth? Grain size is not just a factor of settling velocity, but a major factor is distance from the source of sediment.
This is getting complicated, at least for me.
It is for most people. I've mentioned this to Faith a few times.
If you look on the left side of the diagram and count the boundary lines between stratum up from the bottom, then I'm looking at the stratum between the 2nd and 3rd line up. That stratum runs right into the basement rock, not pinching out or anything like that. The whole thickness of that stratum just dead ends at the basement rock. So do others. How does that happen?
This is partly an artifact due to scale. In fact, you have hit upon a shortcoming to the diagram that I mentioned a day or so ago. I explained it as not being able to show an effect that occurs over a short distance, especially where there is vertical exaggeration. It could also be a problem with the way the diagram was drawn by hand, making it hard to change. The problem is that it makes the contact look intrusive (i.e., the contact cuts across bedding planes and is therefor younger than the bedding). However, the depiction of cobbles tracing along parallel and above the contact assures the interpretation of an erosional surface.
I see the circles representing the conglomerate at the base. It is continuously there across the top of the boundary to the basement rock. Here's the full diagram:
Yes, in this case the cobbles could not be moved very far from their source.
I think you're saying that the conglomerate got there by erosion from the basement rock, and that much of it might be there by lag erosion (is that a term), water or wind flow strong enough to carry away smaller grains away but not larger/heavier conglomerate. Do we know the story in any more detail? What caused the basement rock to break up into so much conglomerate?
They would be termed lag deposits. And sure, just look at any weathering granite mass and you can often see everything from house-sized boulders that have barely moved to fine 'grus' (decomposed granite, sometimes called "DG") and soil that can be carried away by currents.
The stratum at the base of the left side of the diagram all end at that basement rock. Could they all be marine deposits of a rising sea?
That is exactly the interpretation. Notice that the layers follow Walther's Law.
Wouldn't that mean that the deposits should show evidence of Walther's Law, perhaps with the rising water going into or out of the diagram?
Well, in transgression, the shoreline should be rising up against the land mass. While Walther's Law would be shown in the horizontal layering, each layer would have a boundary against the granite containing fragments of the granite (assuming it is actually granite).
Here's a closeup of the layer with multiple lines of circles:
Possibly. Oftentimes, bedding isn't really clear in conglomerates, and remember this was a hand-drawn diagram that has to be schematic in a lot of respects.
In that layer that has one, two or three rows of circles in a line (the number depends on thickness), does that mean there are "gravels or cobbles or boulder deposits" arranged in sublayers of the stratum? Are the "gravels or cobbles or boulder deposits" also conglomerates?
Yes and in this case a layer composed mostly of gravel means that there is very active erosion somewhere in the region.
And finer sediments are mixed in, called the matrix, I guess? Are the dashes between circles meaningful, maybe referring to the matrix?
Yes, that would be the symbology.
Is the composition of the stratum uniform, because if the "gravels or cobbles or boulder deposits" are what you mean by conglomerates then the conglomerates in this layer do not reside at the base of the stratum.
Correct. When the gravels are detached from their source, they are transported. This required higher energy streams and/or steeper gradients.
Are the large number of fine diagonal lines throughout the diagram meaningful?
Ah, someone noticed ... Without a legend, I am not certain. But if you notice, the diagonal lines that cut across the bedding and are confined to the pre-Devonian. Those would be the rocks affected by the Caledonian Orogeny. I think they represent fractures related to folding of the rocks. While it would be hard to show innumerable folds in such a diagram, the fracturing would be relatively easy to schematically portray.
Since there's a layer with little dots labeled Lower Greensand, I assume that little dots mean sandstone.
Yes, this is standard symbology.
So looking this up I see that cobbles are a type of conglomerate.
I'm using the terms for larger grain sizes interchangeably here. But yes, each term has certain connotations.
I feel more knowledgeable in the sense of learning something by rote rather than through understanding, that I need to get a better feel for this.
It is a different way of looking at the earth. It takes time, despite what Faith seems to think.

Yes, there have been many orogenies across the world occurring at different places and different times. In the GC region there were no major orogenies for most of the Phanerozoic.
Does the time factor work out?
Not for you.
That is, is there time for those orogenies to have grown up and been eroded down between the strata as found in the Grand Canyon just for a comparison?
Sure.
This is what I meant by the "contortions" the standard interpretations have to go through, but oh well. At least I see better why we can't communicate about this stuff.
I see no contortions. Please elaborate.

That just seems apparent from the illustration itself.
Some punctuation would make your posts easier to read. Everything you see would be attributable to erosion imposed on a tilted package of strata.

No magic at all, just a volume of water millions of times greater than any of you seem willing or able even to TRY to imagine. Which you imagine without any basis in reality did impossible things contrary to the laws of physics and without leaving any evidence. In doing so, you are invoking magic. Your next magic trick is to imagine without any basis in reality that the laws of physics were completely different than they are now. No evidence of that, no explanation for it, no nothing except your magical wishing. So yet again, MAGIC! Magic is as magic does. You keep invoking magic, so that means that you are indeed using magic. Just admit the truth, that you are using magic, and stop pretending that you are doing anything like science. BTW, all along you have been playing your games in accordance with the fundamental deception of "creation science": that their position and claims are not based on religion, but rather are based entirely on scientific evidence. That fundamental deception was designed to circumvent court decisions in the wake of Epperson v. Arkansas (1968) which invalidated the use of religious reasons to bar the teaching of evolution in the public schools. So the anti-evolution movement created "creation science" as its game of "Hide the Bible" (literally!). And to make matters worse, there is no scientific evidence to support their claims, but rather they have to misunderstand and misrepresent the actual evidence when they are not outright fabricating it. Every time a creationist tries to appeal solely to scientific evidence, she is playing the game of that fundamental deception. Why must your god be served solely through deception?

Faith writes: By river I assume you mean one where the water is flowing. Sediments do not fall out of active water, such as that in a flowing river. These things have been illustrated here before, flume experiments... I addressed the Bertault flume experiments in the very message you're replying to. I said that they deposited sediments at a steep angle, not horizontally. This is queued up at the exact right spot in case you don't remember:
...and even the incident where a whole stack of sediment layers was laid down all at once by a flooding river. What flooding river? If you have evidence that multiple distinct sedimentary layers can be laid down simultaneously, something you've never before claimed about the flood, then please present it.
And river deltas do layer sediments, and I assume the water is flowing at that point. The energy level of the water from the river drops when it reaches the sea and with increasing distance from shore. This has been known like forever. How is this evidence for your flood?
There is also, again, the fact that a flow from Mt. St. Helens laid down a whole stack of strata simultaneously. Mount St. Helens did not lay down a whole stack of distinct strata simultaneously, but how is a volcano evidence for your flood?
I know you want evidence and it is out there and really should be found and produced here but I'm a bad person, as you know, and not up to it. You're here to make the case for your views, which requires evidence and rationale, not just taking up space with empty claims. --Percy

quote: But it makes a big difference to the angles. The differing scales will make the angles seem closer to vertical. This is High School mathematics. Try drawing two right angled triangles, one twice as tall as the other. Take a look at what that does to the angles.

Faith writes: The flume experiments simply demonstrate that water DOES deposit sedimentary layers. See previous message about the flume experiments, which deposited diagonal layers, not horizontal.
There are many ways water layers sediments. Precipitation is one. Is precipitation out of solution something you're proposing for your Flood? What is the evidence that any significant portion of the Earth's sedimentary layers were due to precipitation out of solution?
The point is that it's WATER WATER WATER that accomplishes this feat, and the Flood provided a LOT OF WATER. "Water did it" explains nothing. You're supposedly here to show that the Flood really happened. Show us the evidence so we can see for ourselves. --Percy

Faith writes: edge writes:
The point I was making was that according to the fossil record we got mammals in a lot less time than we got an enormous variety of trilobites that didn't evolve into anything other than trilobites over hundreds of millions of years. I find this to be an interesting evidence for simple mechanical deposition of the creatures and a strong suggestion that the evolutionary interpretation is wrong. Again, this is just your assertion. If you can have rapid microevolution a hundred years, why not macroevolution in millions of years. Mammals are a class. Trilobites are a class. The spans of time are not that different. Trilobites became extinct after a run of about 275 million years. Mammals originated about 300 million years ago. There is no indication of either the Trilobite or Mammal class evolving into anything else. But you're drifting off-topic, which was the fossil record of increasing difference from modern forms with increasing depth in the geological record. How is this evidence for the Flood?
You have not established that the fossil record is only a couple thousand years at most. I believe i established that with the GC/GS cross section years ago, and repeated many times since. The evidence is there that the whole area shown on that cross section had to have occurred in a very short period. And I believe the cross section of the UK which has been under discussion here is support for that conclusion. You are again claiming to have presented evidence that you did not. Just as you're doing here, you said some words that made no sense and withstood not the slightest scrutiny. This is a new thread. If you have a case to make supporting your premise that the Flood really happened, then you should make it now. --Percy Edited by Percy, : "300 years" => "300 million years"

quote: This is where you are using very confusing terminology. Many strata are in part above sea level, but those portions are not separate strata, nor do they rest on the line - which corresponds to nothing physical that they could rest on. Further, Not only are they are not vertical, they are much closer to horizontal than they appear in the diagram because of the differing horizontal and vertical scales.
quote: They have been tilted, obviously. Their extent has likely been reduced by erosion. But it is not at all clear that they all covered the entire island. In fact that seems quite unlikely.
quote: I’m not at all sure of that. The sea level has nothing to do with their original position, and I am sure that there is more folding than collapsing here. (So the presumed Cambrian layer at the bottom of Snowdon - which is not bounded by sea level - has likely been raised from it’s original position).
quote: It’s more complicated than that because there are multiple tectonic events going on. A single pivot at Snowdon will not undo the bending of the strata, so it will not make all the strata parallel. And what do you make of the Silurian deposits directly underlying early Cretaceous - or perhaps late Jurassic - strata at the Eastern end (beneath the Cretaceous label, and identified as Silurian)?

Faith writes: SO what it was pyroclasitic, it was a liquid flow. Water is a liquid you know, would behave similarly as a flow. A pyroclastic flow doesn't deposit multiple distinct layers simultaneously as you claimed. It also isn't clear why you're claiming thiss since you've never said the Flood did that. Please explain why you think a pyroclastic flow is evidence for your Flood. Here's a pyroclastic flow from Mount St. Helens. Please point out the multiple distinct layers that were deposited simultaneously:
