So, why were the Supergroup rocks not affected by the 'pressure and heat'?Edited by edge, : No reason given.

Well, the upper part of the Supergroup was. The lower part was probably just not subjected to the pressure as the upper part was. The movement stopped short of affecting it. Something like that.

Prove it. But you believe that those sediments were laid down by water, don't you? Why? Have you never heard of tectonic uplift?

Yeah, just like there is way more pressure when you are 1 foot under water and way less pressure when you are 5 miles under water. Yeah, that makes sense.

Where do you think the GC strata were deposited?We have shown you plenty of cases where strata contacts are not 'straight and flat'. Why is that? I'm sorry, but as the column you have been shown shows, there are plenty of irregular contacts. Or it could be that there are pelagic sediments and terrigenous sediments. But why couldn't you have seas on the continents?Here are some definitions from MWonline and Dictionary.com. Please explain why they do not specify 'straight and flat' formations and that they are only found 'on the continents'.

Strata: a layer or a series of layers of rock in the ground.

Geological Column: 1 : a columnar diagram that shows the rock formations of a locality or region and that is arranged to indicate their relations to the subdivisions of geologic time. 2 : the sequence of rock formations in a geologic column.

Please present some evidence to that effect. I have never heard of anything like that.

Or it could have been eroded away.That's far less complex than moving parts of the Supergroup downward into the Vishnu and converting it to a metavolcanic rock. Well, one of the advantageous of religion over science is that you have certainty. But you always fail to mention how this penetration occurred without any evidence of shearing.

That's one of the funny things about ad hoc explanations.

Well it pretty much was eroded away only "away" into the basement area as rubble that became schist. Something like that. But it's just all that stuff everybody's been complaining I didn't take into account so what's the problem? I'm now taking it into account by hypothesizing that it became the Vishnu schist, rubbed to rubble by the contact with the Tapeats and scattered hither and thither beneath the Tapeats. Lots and lots of rubble. Lots and lots of Vishnu schist that's sort of a hardened rubble. Works for me. The only certainty I have is about God, certainly not science. But I did become convinced because it fits so well with the whole scenario. The quartzite wouldn't have sheared the Tapeats because it went THROUGH it, so maybe it would have dug a trough in it as the Supergroup moved along under it. A trough I figure would have closed up when the movement stopped because it's still all soaking wet. (After considering various possibilities on the timing I've pretty much decided the whole upheaval starting with the splitting of the continents was the point at which the Flood began receding. Volcanism certainly got started then, and the sea floor must have been affected in some way that made room for the Flood waters.

Please show us a picture of how this happened. How do you get SuperGroup rubble from above the SG into the schist below the SG?And no, your process should not be confused with the erosion of rocks by weathering and breakdown and transport of minerals. But your explanation does not make sense.And it is not just under the Tapeats. It is under the supergroup.And the rock fabric in the Vishnu has no releationship to the Great Unconformity.And there is no cataclasis of due to faulting along the Great Unconformity.But then, that would work ... for you. So, as I said, you have certainty. This is a characteristic of religion. That would include shearing. In that case there should be no primary textural elements in the Tapeats. And yet we see bedding.Why is that?You said that the entire section to the Fort Union was deposited prior to deformation. Do you really think that the Tapeats was still waterlogged at that point? Why do we see evidence of brittle deformation in some of the GC rocks? Well, if you've decided all of this, that settle it for me ...

The pressure would have come from the weight of the strata above as the Supergroup pushed up into the Tapeats and the heat was caused by that action, so when the movement stopped that also stopped. That's my guess.

Your record at guessing is not very convincing.Could you tell us why the foliation of the Vishnu schist does not bear any geometric relationship to the Great Unconformity?If either the weight of rock or movement along a fault were responsible for the pressure and temperature, then there should be some kind of evidence that they are related.

I'm convinced but that doesn't mean I couldn't become unconvinced if I had really good reason too, and that's not the kind of certainty I have about God.The schist also occurs directly under the Tapeats so it could have been moved horizontally from the Supergroup.Depends on where you see the bedding.Wouldn't brittle deformation be a later event?

For some reason I doubt this. That's what I said. Anywhere. Just give us an example. Okay, describe the later event.You have never mentioned this before, AFAIK.And remember, your tectonism that occurred while the whole stack of sediments was water soaked had to be strong enough to show no deformation due to all of the commotion of the Supergroup being forced upward into the Paleozoic section. How doe that work?

Most strata elsewhere didn't survive the tectonic forces but for some reason the canyon area did to a great extent, at least up to the Permian: the Mesozoic and Cenozoic rocks of the Grand Staircase were tilted in such a way that the receding water removed a lot of it and left cliffs; and it broke up miles of strata above the canyon before actually cutting the canyon itself from the Kaibab down while leaving most ol the walls intact. Even wet it would have been highly compacted. However, the canyon was certainly affected as you can see all the exposed remains of the walls everywhere, and the odd bits of intrusion between lower strata in the Tonto group I recently commented on I figure were also caused by that upheaval so it isn't as if NOTHING happened.
