Coragyps has addressed the chemical reactions that you have to explain, TC... I will chime in to clarify this question you raised:
quote:
--What data have you considered in deducing that I have to have enough organisms grow during their deposition?
This follows from simple logic. Consider your model, TC, either:
(1). the creatures in the geologic record were deposited by normal non-Flood sedimentation before the Flood, or
(2). were all killed at the same time (and thus were all alive at the same time) and deposited DURING the Flood, or
(3). grew very rapidly in the midst of the raging Flood, or
(4). lived and died AFTER the Flood in normal non-Flood sedimentation.
If you really want to cram all the Paleozoic and Mesozoic into the Flood, that means (1) and (4) are fairly small contributors to the fossil record. Limestone and dolomite are, in fact, quite rare in preCambrian sediments.
You are left with having almost all limestone suspended in the pre-Flood water column, either as (2) living creatures, or else (3) as dissolved ions followed by some really incredible growth DURING the Flood.
Option (2) fails for opacity, lack of surface area for bottom dwellers, lack of oxygen, food, and CO2 poisoning from the respiration of all those animals.
Option (3) fails for the obvious reason of insufficient light to support the required amount of growth in only one year, as well as insufficient solubility for Ca and Mg (cold water can't hold much dissolved ions), insufficient solubility for carbonate (hot water can't hold much dissolved CO2), the heat and CO2 generated by the reaction, etc.
It's time to open your eyes, TC. The only options left that can explain the gelogic record are options (1) and (4) - normal sedimentary processes operating over very long time scales. The Flood must shrink into it's proper place with all the other myths - rising sea-levels from melting Ice Age glaciation left a profound impact on prehistoric cultures, which were undoudtedly mostly coastal and forced out of their prime ocean front real estate. Think about how tough it will be on your kids and grand-kids when most of Florida is under water. The survivors will not be all that welcome, I suspect, here in the hills of Virginia (no offense intended, just the harsh realities of global warming).
Consider the real world and how poorly your myth explains its features. This paradigm shift must be even harder than replacing Santa Claus as the gift-giving mechanism is for little kids, but easier than the Tooth Fairy (that one always seemed a little strange... to me, anyway).
I think you can do it, you're still young, still able to learn and expand your world-view.
