Evidence that the Great Unconformity did not Form Before the Strata above it

How is that different from depositional processes going on today?In other words, why must it be a biblical flood?

OKay, good. Perhaps you'd entertain some suggestions as to why that cannot be so.For instance...If we trace Pennsylvanian aged rocks from the Grand Canyon to the east, we find that they become more and more coarsely clastic, meaning that more and larger rock fragments make up the units. Then suddenly, they disappear against a major fault with crystalline intrusive rocks on the other side which look very much like the material being eroded to form the sediments.Most of us would interpret that as a tectonic event occurring during that time period, with deeper basement rocks being uplifted and exposed to erosion whereby sediments are shed from the higher lands above sea level.In other words, this depicts a tectonic event on the edge of the Colorado Plateau rocks in the middle of your global flood. That would negate your proposal that there was only one tectonic event, only occurring after deposition of the entire section of sedimentary rocks.What say you?

Actually, for once, I understand what you are saying AND what Faith is saying (though the latter still takes some interpretation). I am sorry that my jargon is kind of difficult to understand, but I must add that I have had some pain lately and kind of rush things once in a while.But yes, your understanding is correct. Using fossils and mapping techniques, we can trace a specific age and 'tectonostratigraphic unit' virtually across continents. In this case the Pennsylvanian aged rocks can be traced to the Ancestral Rockies from which they were eroded. This can be done from surface exposure and from subsurface data (drilling).What Faith is saying is essentially, that this cannot be done.I, obviously disagree. Here is an outline of the Paradox Basin in between the Grand Canyon on the lower left and the Uncompahgre Uplift in the upper right. Here is a cross section of the Pennsylvanian rocks, although in reversed direction. In other words the NE end of the section is to the left side. It shows a changing depositional envvironment from the Supai Formation on the right in the GC area to the Cutler Formation alluvial fans and the uplifted granite in the east (left side). I think one can see the source of the alluvial fans (conglomerates) being shed from the uplifting granite highlands.The point is that this all makes sense from the fossil data to the reconstruction of the Pardox evaporitic basin. Notice how thick the rocks are on the left side of the diagram showing the amount of sediments being deposited in that area due to its proximity to the source. I trust that the fault which uplifts the granite is easily seen and understood.Feel free to ask questions.Edited by edge, : No reason given.

Frankly, I would be happy if Faith just agreed to disagree and say simply that, "I don't think you can trace the Supai Formation into the conglomerate fans of the Cutler."However, the problem is not just weird explanations of faults that have no evidence and cannot mechanically exist, but then there's the odd arguments that are totally unnecessary, brought up (apparently) simply to be disagreeable.In her defense, it appears that she is trending in the direction of admitting that she has no evidence and simply disagrees based on a biblical interpretation (and not science).I think this way it is possible to have a discussion. The previous mode prevented discussion.But then, I could be wrong...

Yes, and that is exactly why I mentioned that I can accept the argument that someone believes this can't be done.I disagree with it of course.There are a few misconceptions along the way, though. First of all, they are not 'the same kind of rock in different forms', they are different rock types demonstrating different depositional environments in existence at a same time. Remember Walther's Law...Now, if we just propagate the environments upward, we get the same picture as the cross-section shows.(This may be hard to visualize, but, by 'propagating upward', what I'm really saying is that the basin is subsiding rather than having the sea transgress across the continent ... does this make sense?)So, as the mountains on the left rise, they shed alluvial fans into the basin. If the basin keeps subsiding the fans keep forming through time (upward).As a point of clarification, note that the wavy horizontal lines represent specific points in time.So, the point of the argument is, can we trace from one contemporaneous rock-type to another? I think with transitional contacts and interlayering units, it is easily done by simple geological mapping; and with fossil evidence, we can confirm the conclusion that one formation is the time-equivalent of another. I do not intend to 'prove' this for the Pennsylvanian formations of the Colorado Plateau, but I will accept previous work of others because of the predictive pattern it creates. As further confirmation, these basin models are used extensively in the successful exploration for oil and gas resources along with certain types of copper and uranium deposits.Feel free to ask questions if I'm not being clear.

More to the point, how do you get these deposits, which signify rapid erosion (conglomerate fans) during a time when Faith says that there was no tectonism, or erosion?And clearly, something was going on to create lateral changes in rock type and thickness right there in the middle of a single, global flood.Even if you don't accept the equivalence of the Cutler rocks to the Supai rocks, you need to wonder just why these deposits formed long before the end of the flood. After the Cutler. there is still a long geological history recorded in the rocks as the continent shows a change from marine deposition to more terrestrial rocks of Mesozoic time. How does that fit into the 'one-flood, one-volcano, one mountain-building event such as Faith proposes?ETA: This is exactly the point.In the past, Faith has demanded that we restrict the discussion to the Grand Canyon area, but if she is saying that there was no tectonism or erosion on a global scale that makes her argument specious. Edited by edge, : No reason given.

Wow...Intrusive conglomerates.I wonder why no one ever thought of that before. You're right, it's not easy.I'm just trying to imagine how these conglomerates were deposited after the flood and then, somehow, forced themselves down the fault zone and then out into sediments that were deposited midway through the flood.A difficult thing to visualize. So, all of these things happened after the flood.That's kind of odd since these processes are happening to old layers within the rock record. So, the record of eroding mountains in the record was injected or produced by some kind of alteration of the original rocks?Please proceed with explaining your idea that conglomerates are intrusive. And remember to explain why they are found close to older rocks that are the source of the rock fragments.

Here is what one source says: Check it out sometime during your vacation. Despite what you think, tectonic breccias are readily discernible from conglomerates.

I'm sure it's possible, though I'm not sure how. Possibly related to caliche deposits or the presence of certain plant fossils.

Well, I wouldn't say that not seeing things in 3D the only fault. For instance, there's the lack of evidence for intrusion of the conglomeratic fan deposits, along with no mechanism for intruding them into the sediments which happen to be what we'd expect for adjacent depositional environments.Just another one of those weird coincidences, I guess. I'm not. I'm pretty sure that a grade school child could come up with something similar. Well, usually we don't pat people on the back for coming up with outlandish interpretations that have no evidential support.I suppose we could start. Anyone in favor?
