The Genesis Flood Boundary Discussions

When reading creation science publications, you are likely to see the expression "Flood model" in geology. (Regular readers have seen it here.) The way I figure it, this is a sort of general expression because there are actually several models of the Genesis Flood processes, but most are in agreement over the main points.

Genesis Flood geology has models, hypotheses, disagreements and discussion

Geologists of the biblical creation persuasion agree that the Genesis Flood actually happened, and it happened a few thousand years ago. Their models are far more effective at describing what is observed in geomorphology and other areas than secular uniformitarian dogma. Flood geologists have their hypotheses and models. However, when scientists do science stuff, they disagree on details. Was there a post-Flood boundary? If so, where? How does it compare to other boundaries? Why do secular scientists shy away from the unique continental shelf and slope?

Models are run up the flag pole to see if anyone salutes them. There is disagreement, and serious dialog is requested from several geological disciplines. Some hope to reach a consensus so they don't have all those models floating around.
An integral part of any comprehensive Flood model is discerning the distinction between Flood processes and post-Flood catastrophism in the rock record. The characteristics of the continental shelf, slope, and rise suggest that the location of the boundary was reasonably synchronous on a global scale. However, there is no consensus among Flood geologists on where the post-Flood boundary should be placed. The geological column concept provides a useful framework of discourse for examining different approaches to the post-Flood boundary among creationists. There are three main schools of thought: (1) the Precambrian/Paleozoic Boundary Model, (2) the K/T Boundary Model, and (3) the Late Cenozoic Boundary Model. Each one makes different assumptions and has specific issues that need addressing. Multiple criteria spanning several fields of study need to be used to examine this issue since just one can be equivocal.
