That is basically what I would expect. My question boils down to this: if these deposits were formed during the flood, then how did the sea level drop close to the current level and rise back up to 10s-100s of meters above current sea level multiple times; or, if the deposits are post-flood, then why are there no records of repeated changes in sea level of 50 meters or more? Correlation with other formations dates those that I am most familiar with as Plio-Pleistocene, though the issue comes up from the Upper Cretaceous onwards.
