Author | Topic: Evidence that the Great Unconformity did not Form Before the Strata above it | |||||||||||||||||||||||||||||||

Okay, let's put it this way... Why do you care that the unconformity surface is so smooth? THAT IS A TOTALLY IRRELEVANT QUESTION. I NOTICED HOW AMAZINGLY STRAIGHT AND LEVEL THEY ARE AND THAT RAISED THE QUESTION HOW A MILLION PLUS YEARS OF EROSION COULD HAVE DONE THAT.
NATURALLY FLAT AND LEVEL. UNLIKE SCHIST AND TILTED STRATA. SHEESH. YOU NEVER READ ANYTHING I WROTE DID YOU?

THE FRUSTRATION COMES FROM PEOPLE NOT READING WHAT I WRITE AND NOT THINKING AND IMPUTING RIDICULOUS NOTIONS TO ME.

edge writes: Faith, how about you check out my post Message 286 and tell me if it satisfies your demands. Please tell us what formed that surface as shown if not erosion? -- That's the sort of formation that is often part of an angular unconformity, and if it was then the upper part washed away and the lower part was then exposed to erosion. Otherwise it was formed by erosion, which IS WHY IT IS NOT STRAIGHT AND LEVEL LIKE MY EXAMPLES IN [MSG=213] ---
Then check out me post Message 281 and tell me that the rocks under the modern erosional surface are not tilted. ---I can't even see that formation in the distance. --- Edited by Admin, : Add missing quotes. The original style left it very unclear which words were Faith's and which were Edge's. For some reason Faith has put her own words (at least I think they're her words" between dashes.

You aren't understanding the simplest most obvious things and I can't stand it any more.

I cannot make out the formation in the background.
There is nothing in the foreground but some battered boards of what was probably once a wharf. No, have it YOUR way about the other picture. Sure, just as straight and level over as long a distance as the contact in the G.U. Edited by Faith, : No reason given.

So. Here's a picture of the V. schist with the Tapeats sitting on it. And there's a narrow ledge in front of the Tapeats, which shows how flat the top of the Vishnu is. Of course to me that flatness couldn't be the result of erosion over some long period of time.
You think that little Colorado river managed to cut the entire canyon through every kind of rock and yet you think erosion would have left a flat surface on top of the Vishnu and even a flat surface that cuts horizontally across the uptilted strata of the Supergroup. Oh well. The geologists must be right. Now is what I have written here simply incomprehensible? Will it be argued that it isn't REALLY flat, flatness is a relative term, and there's eroded material piled up on it too so we can't really tell a thing about it? Or will I just be asked, Why do you think that?

Googled "erosion" to get some images to explain why I think years of erosion would never produce a flat surface. None of these address the situation at the contact of the Great Unconformity with its lumpy schist or tilted strata base, but it clearly has severe enough effects on flatter surfaces. And if you did get a flattish surface from the erosion of those very bumpy surfaces, the sort of thing shown in the pictures should be expected to happen at that point to that flatter surface.
However, the Great Unconformity contact is amazingly straight and level, flat and horizontal, much more so than the surfaces in any of the pictures put up by HBD and edge recently. Go to my Message 213 and Message 313 to see what I mean. {Also note that in 213 that I did say which kind of surfaces are already flat or "depositional" surfaces as edge prefers I call them: I mentioned the Kaibab plateau and the tops of buttes, mesas, tepui. To make it clear the problem is not with those but with the very irregular kind of rock that is clearly very flat at the G.U. in the pictures I posted. }

The processes that cut into the land aren't going to stop when a given trench has been filled with sediment.

"Flatter" is not as remarkably flat as the GU in the images I posted in 213 and 313. And again, get your surface as flat as you can, does the rain stop? Does the wind stop? If not they are going to continue to cut into the surface and unsettle its flatness.
ABE: And didn't any tectonic events occur to raise the land either? Edited by Faith, : No reason given.

irrelevant, Dr. A because I drew those blocks to show what I thought they were like originally, but they have supposedly been "eroded" to their current horizontal flatness, which can be seen on the standard cross sections and in the messages I keep referencing: 213 and 313,

Far as I know images of how rock erodes aren't available.

You are never going to get such perfect flatness that there won't be some differences in elevation to get erosion started, even if only inches.

Don't see any cracks in those G.U. contacts.

So you think the basement rocks of the G.U. were once like the Great Salt Lake? And all that schist and/or tilted strata was buried beneath the surface?

more pictures of rock eroding
Let me know when it's eroded down to a surface as level and straight as those I've illustrated of the G.U.
