Most scenarios imagine the flood to be extremely violent and chaotic; how
could such a catastrophe produce an "orderly progression of layers"? Modern
local floods, even large scale events, lay down a single thick layer
consisting of a jumbled mixture of silts, sand, gravel, rock, debris, etc.,
and not an "orderly progression of layers"; how could a global flood do what
modern local floods could not? Why is it that the geological record often
shows layers of gravel-based sediments overlaying sand-based sediments which
in turn overlay silt-based sediments, when everything we know about
hydrologic sorting tells us to expect exactly the opposit arrangement?
>...briefly the lower (Paleozoic) being mostly marine....
What about the layers that were clearly formed from dry land sediments? I
don't mean sediments eroded from land that were deposited in water, but
literally a petrified desert layer between two marine layers? Did the flood
dry up long enough for the surface of the earth to dry out and desertify
before being reflooded again?
>(Mesozoic) including much land-derived material eroded by rising waters....
Again, how do you explain layers that were clearly dry land sediments, such
as deserts or forests, being found between marine layers? Remember, the dry
land sediments were not eroded into water for deposition, but were exposed
to air (I don't know what the proper geological term is that distinguishes
non-water-borne sediments from water-borne sediments).
>...and the upper (Cenozoic) mostly resulting from decreasing sea levels and
>subsequent tectonic adjustments.
This time, how do you explain marine deposits being found between dry-land
layers above your flood horizon? Did the flood return for short periods
despite God's promise?
The identification of layers as water-borne or dry-land sediments is
independent of your artificial dichotomy between flood/short-age and
evolution/long-age models. In other words, a petrified desert would be
identified as a petrified desert (and not a mass of petrified sand bars)
regardless of whether geological history was considered to be long or short.
Can your flood model explain alternating layers of water-borne and dry-land
