I’d like to hear from a geologist on this one, since I know very little about geology. I don’t remember who in this forum is a geologist, so feel free to tag one for me!
I was talking to a YEC friend about the folded rocks article on AiG, the one where they say there are no cracks, but then other (better) photographs show very clear cracks. My friend asked if anyone had contacted AiG about it. I’m sure many have, but I decided to ask them myself. The response they gave me from Dr. Snelling is this:
“The fractures referred to in that photograph are not due to the folding event itself. Closer inspection of the outcrop and those fractures, plus examination of the rock matrix itself under a geological microscope, reveals those fractures could not have occurred during the folding event when the rock was still moist and its cement not yet set. Instead they are fractures that were produced well after the rock layers were folded (while still soft), when months or a few years later- as the cement in the rock subsequently dried out and shrinkage occurred. Those are drying and shrinkage cracks, not folding cracks.”
To my layman eyes, this looks like he’s assuming the folding occurred while the rock was still soft? If folding occurs under intense pressure and heat deep in the earth, does it become soft during that? Was this formation deep enough for that kind of folding? Are there any peer reviewed papers that talk about this particular formation that explain how the folding occurred?
