Re: turns out there is no correction to age measurements

When rocks form and when mountains form are two distinctly different things.
When mountains form, they can change one kind of a rock into another. They can take flat layered rocks and turn them into folded layers or they can fault them. The rocks that are in mountains are generally not in the same condition that they were before the mountain building event.

Re: turns out there is no correction to age measurements
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.

Re: Folding soft sediments

Well, he was talking folding lime mud, sand, and silt, not clay. That material may indeed just get all mixed up together . He was SORT OF on the right track, but didn't get it totally correct. Or something like that.
But Pressie's point is that there can be soft sediment folding. FEY, see the Wiki article on soft-sediment deformation structures. Especially see the convolute bedding section. This deformation is probably usually (yes, weasel words) pretty small scale. You are not going to find large scale soft sediment folding (other geologists welcome to tell me I'm wrong).
FEY, see what happens when you adopt the mainstream geology orthodoxy? Someone's going to hit you with the exception to the rule.
Well, the stiffness of modeling clay isn't what I had in mind when I made my claim. I was imagining something very wet still. Even with modeling clay, you get a mixing of the layers if you continue to squeeze it and roll it around in your hands. I remember getting gray colored balls as a result when I was a kid.
