mindspawn, this is not what is found in my country.
You forgot to mention Gondwana coal. Wasn't the global flood supposed to cover the whole earth?
quote:
Percy, its the coal deposits that make the difference for me. Carboniferous coal deposits speak to me of the pre-flood swampy regions of earth.
  —mindspawn
The Carboniferous coal seams in my country are very thin and very intermittent. They are found in glacial deposits of the Dwyka Group. Deposited around the Carboniferous/Permian boundary.
quote:
Permian deposits are more mixed, the fossils less intact.
  —mindspawn
In my country we do have lots of coal seams in Permian deposits. In the Main Karoo basin they are normally found as 8 seams; with different strata seperating those seams vertically. The two seams with the best quality coal which are normally mined, are the number 2 and number 4 seams, seperated, in places, by hundreds of meters of sandstones, shales and mudstones. Normally they are abot 60 metres apart, vertically.
quote:
A flood would by necessity cause both types of coal deposits because it would cover over swampy regions of thousands of years of accumulated deposits (peat),
  —mindspawn
Well, it seems like this didn't happen in my country. The flood must have missed it.
quote:
...and also create new deposits of vegetable matter that would form into coal over time after flood deposits and subsequent deposits compress it.
  —mindspawn
Please explain how one flood would deposit a coal seam, then deposit hundreds of meters of sandstone, shale and mudstones, then deposit another coal seam on top of all that. Then deposit sandstone, shale and mudstone strata, then another coal seam on top of that. And then does it again.
quote:
Looking at the geologic layers, what is known as "Carboniferous" coal and "Permian" coal best conform to these two expected layers of coal.
  —mindspawn
Well, it seems as if we have more than 2 "layers" of coal in my country. We even have Triassic coal seams, too!
The "global flood" must have missed it. It wasn't global, I guess.

Yeah, try folding unlithified sediment. All you get is a mixing of layers. If you had lime mud in one layer followed by a silt layer followed by a sand layer, any attempted folding of those layers would result in a mixing of those layers which if lithified at a later time, would turn into a dirty limestone or a sandstone with a calcite matrix or a silty limestone.

Really?
Take one yellow layer of play clay. Put a red layer of play clay on top of that. Put a green layer of play clay on top of that. Put this sequence on a table. Compress gently from the sides. You get beautiful folds and those layers of play clay certainly don't mix.
So, unlithified layers don't necessarily mix when they get folded.....

Re: turns out there is no correction to age measurements
Dr Adequate, it certainly does illustrate that unlithified sediments can be folded without mixing of the layers. So foreveryoung can't make a blanket statement about everything.
He should have a look at rheology before making blanket statements. It explains how "unlithified sediments" can and do get folded without mixing. In real life, for geology, heat and pressure are some of the most important ingredients.

Yeah, the Plasticine Epoch really, really was funny. I actually spilled my coffee on my keyboard!

Re: Folding soft sediments
Yip, you're right. I don't know of any large scale soft sedimentary folding (as in deposited now, folded a day or two or a few years later all in one go) in any sedimentary sequence. However, it certainly is possible.
My idea was to indicate to creationists that real scientists have investigated those possibilities and can recognise them in the geological record if they are found.
Those creationists always think that "evolutionists" ignore everything, because it could indicate "The Fluddy" and of all of science is just done to deny their versions of their beliefs..
