You have never explained the idea of erosion as a unit. Explained it many times. See Message 419 The Grand Canyon itself. Various layered formations. The Monument Valley buttes, the hoodoos, the Grand Staircase etc etc etc. Edited by Faith, : No reason given.

So erosion as a unit just means exposed cross-sections getting eroded? That’s really not evidence for anything significant.

Yes
And your blocks are unchanging as far as size and composition?

Oops, depends on what you mean by "unchanging." They are what they are, they don't change. So if that's what you mean the answser is yes they are unchanging. Realized I don't know what you mean by "unchanging." I'm sure they will go on eroding but that's the only change I can think of. Edited by Faith, : No reason given.

Fine. All I mean is that they change in time. In size or composition, etc. Just trying to figure out how someone could be so confused. So when the GC Supergroup was deformed (faulted and tilted), they were still part of the block that contained the Paleozoic rocks above, right?

minnemooseus writes: Remember out favorite "Walther's Law" diagram:
The bottom left of this diagram illustrates the difference between lithostratigraphy and chronostratigraphy. As you go right to left, the lithostratigraphy (say, the sand unit) becomes progressively younger. And the top surface of the various sediments are the "landscape" of the time. It would probably also be useful to explicitly point out to Faith that by "landscape" you mean seascapes being created according to the principles of Walther's Law. These seascapes that become preserved in the stratigraphic record are not the landscapes that the sea transgressed across. Those landscapes are gone, ground away by active coastal waters into sand, silt, mud and clay. The constituent elements of the landscape are preserved as particles of sediment. For example, if the landscape was rich in some element like iron, then the marine sedimentary layers will include that element. I interpret "landscape" to be the sums of all the "solid surfaces" of a given time. By "solid surfaces", I mean the top of geologic materials, below the atmosphere or whatever body of water. Topography and Bathymetry. Topography - Wikipedia
quote: Bathymetry - Wikipedia
quote: Now, per your "created according to the principles of Walther's Law". I still resist invoking Walther's Law as being a process. Recently I discovered a better terminology:
https://en.wikipedia.org/wiki/Deposition_(geology)#Null-point_hypothesis quote: quote: Now, Faith's muddled scenario apparently involves sediment being eroded off the continents and being deposited at ocean shorelines. While I envision that the results of the Faith variation of the mainstream concept would look substantially different from the above graphic, I think that Walther's Law would still be valid. It's still a migrating environment. Faith also invokes large sediment amounts being stirred up in the ocean basins and somehow being washed up into the near shore environment. While there are all sorts of problems with this scenario, I visualize that such might result in a sediment size distribution that goes from coarse to fine from seaward to landward (the opposite order of the "Walther's Law" model). I see this because of the sediment deposition fining as you get further from the ocean basin sediment source. So, the final stratigraphy might be some sort of hybrid of the land sourced sediment model and the ocean basin sourced sediment model. I would expect that even such hybrid would still result in a Walther's Law relationship. Now about a bit of Percy statement from message 556:
Percy, message 556, writes: The ocean floor has not dropped. Surveys of the ocean floor after WWII in order to aid submarine navigation revealed a great deal of information about mid-oceanic ridges and sea floor striping and so on, but not an ounce of evidence for dropping sea floors. As I understand it, the great sea transgressions and regressions in geologic history were indeed largely caused by ocean floor rises and falls. This is the reality that ties into the "catastrophic plate tectonics" fantasy. Over the years I've tried and failed to find good (or even mediocre) internet literature on this process. Perhaps to be discussed further in later messages. Moose Edited by Minnemooseus, : Failure of proofreading.

So when the GC Supergroup was deformed (faulted and tilted), they were still part of the block that contained the Paleozoic rocks above, right? Yes that is my theory/hypothesis of how angular unconformities are formed: that tectonic pressure buckles or tilts a lower section of strata beneath the strata above which remain horizontal, which in the case of the GC remained intact up to the Permian/Kaibab level, while strata above that level broke up and washed away; though in other cases they got broken up at a much lower level, such as at Siccar Point. I think this was a worldwide event, this tectonic pressure and it caused all the angular unconformities everywhere and most of the deformation of strata everywhere and even the major erosion events that left isolated buttes standing. Because it occurred at the same time as the receding of the Flood water. It's a nice theory really. Edited by Faith, : No reason given. Edited by Faith, : No reason given.

However, I think that we need not worry. Such distortions of reality are self-defeating. No one is going to be convinced by such anti-science denial that we see here, and if Faith wishes to cling to a distorted reality, we have the satisfaction of knowing that she represents but one person. An oddity, not a great hindrance to knowledge. My concerns are based upon the effect of such thinking on science education. I agree that Faith's impact on science education is minimal to non-existent - even creationists can detect those parts of her ideas that are wildly impossible. The benefit of discussion with Faith is the honing of ones skills at countering fantasy-based thinking with reality-based evidence and reasoning, and the recognition that even that has only mild chances of success.

The fallacy there is that if the upper and lower parts of the block are deformed separately, are they still a block? I thought that you said they deformed and eroded as a unit, but your narrative here rejects that.

Perhaps you can describe this 'tectonic pressure'. What mechanism would cause a 'global scale' deformation?

A cute theory, perhaps. Something fit for a 'nice' science fantasy novel, but not a theory grounded in reality.

This is true and demonstrably so. We know that the oceanic crust slowly subsides away from the mid-ocean ridges based on depth of the abyssal plains and the subsidence of the Hawaii-Emperor seamount chain. So the principle of isostatic adjustments due to cooling and thickening of the oceanic crust is established. It isn't hard to imagine that increasing the temperatures of the upper mantle over time will cause a rise in the elevation of the oceanic crust thereby displacing seawater across the continents (or cooling for the reverse effect). This is probably the cause of the stratigraphic mega-sequences recognized in the geological record. These are global events even though the may not show up on all continents (as per Pressie). I think what Percy was envisioning was a catastrophic collapse of the sea floor after flood waters were supposedly vented violently to the surface. Of course, this doesn't work. You can't just leave a vacuum where the water had resided ... the seafloor must collapse. But this is an interesting topic even outside of the biblical flood debate. So many things come together with with grand theories such as mega-sequences.

I understand the basics of meander formation, RAZD. ... Obviously you don't. They don't suddenly pop into existence.
... I just went looking at You Tube films of meanders, both actual and animations, and still have the same impression: they make smooth loops, they don't look to me anything like the course of the Colorado over the Kaibab plateau. That is the end of the formation process. They start as a little wiggle, one of many. Rivers are wiggly. Dunning-Kruger. You haven't any knowledge of hydrodynamics, just enough of a cursory knowledge to think you are an expert. Which is a BIG surprise seeing as this is your modus operandi in all sciences.

I thought that you said they deformed and eroded as a unit, but your narrative here rejects that. No, I've specifically said that angular unconformities are NOT a block, specifically said that more than once. Angular unconformities are the ONLY exception to the rule I keep talking about, that LLhe strata were laid down before being eroded or deformed as a whole block or unit; said that many times, I guess you missed it. Angular unconformities are an exception. NOT a block/unit. ONLY exception.
Perhaps you can describe this 'tectonic pressure'. What mechanism would cause a 'global scale' deformation? The splitting of the ocntinents was a worldwide event, that's what I'm talking about. A lot of tectonic bashing and crashing going on. The breaking up must have been fairly jolting, but then there was the subduction on the west side of the Americas that pushed up mountains etc. I happen to think it occurred in conjunction with the beginning of the receding of the Flood, because of the effects like the cutting of the Grand Canyon and Grand Staircase and the other massive erosion events in that area; and the dramatically deformed rocks in other places would be a natural result of such a tectonic bashing. Yes a very nice theory. Puts together a lot of phenomena in one nice neat elegant package. Yes, cute. Edited by Faith, : No reason given. Edited by Faith, : No reason given.

Why on earth would I think I'm an expert, I merely know the basics of how meanders form from reading descriptions and watching videos and animations. It's not rocket science. I certainly said nothing about them "popping into existence" for pete's sake.
