The creationist position on flood geology is often hazy about when (geologically) the flood occurred and which rocks we can ascribe to the flood. I've had it pointed out to me more than once that I shouldn't forget that rock was probably laid down both before the flood and after, but no one has ever specified which rocks are pre-flood and which are post-flood. I remember the ICR's boundaries for the flood being the beginning of the Cambrian and the beginning of the Tertiary, but I've never seen the reasoning for this explained.
My question to creationists is- when (into which geological periods) do you place:
-Creation week rocks? -Post-creation but pre-flood rocks? -Flood rocks? -Post flood rocks? -Initiation of plate tectonics?
Please justify your position: Why do you place the boundaries where you do?
