One would predict no order if all organisms died in a violent world-wide flood. The Green River formation in Wyoming contains some 20,000,000 annual layers, or varves, identical to those being laid down today in certain lakes. The sediments are so fine that each layer would have required over a month to settle. We have ice cores from Antarctica and Greenland with annual layers dating back some 40,000 years. A world-wide flood would be expected to leave layers of sediments and result in alterations of salinity and oxygen isotope ratios.
Some limestones are thousands of meters thick.
Chalk is mostly made up of the bodies of planktonic animals approximately 700 to 1000 angstroms in diameter. This list does not even take into account all of the biological and physical impossibilities of a worldwide flood. Recommended Readings Monroe, James S. 1987.
