|Tonights reason that the global flood isn't workable comes from a comparison of the fossils found in the rock and the physical properties of that rock. We all know about index fossils Trilobites are found in Cambrian through Permian rocks. Certain Conodonts are found only in particular periods of the Cambrian and Ordovician but never anywhere else. Index fossils will be listed below the picture.|
If all the rocks were deposited in a one year period, we should expect that the compaction (the amount of particle packing, should vary only by depth. It really shouldn't matter what fossils are in it. A Devonian (400 million year old) sandstone on the surface is as young as a Pleistocene (3 million year old). Thus we should expect that they should have similar physical properties, like porosity, speed of sound etc.
As a rock compacts, the rock grains are in greater contact and thus, the rock transmits sound waves faster as it compacts. Compaction occurs for two reasons. First is depth of burial in which the weight of the overlying sediments presses down on the rock making the grains be more in contact with each other. The second form of compaction comes with age. Normal processes cause the grains to become more in contact with each other over time. It is what causes settling in a new house build on land fill. Over time, the rock grains compact.
What we find is that regardless of the depth of the rock, rocks which are older (contain the oldest fossils, transmit sound faster than the younger rocks. This simply shouldn't be the case if the global flood were the cause of the sediments. Devonian sands on the surface are always faster than Pliocene sands on the surface. It is as if the Devonian rocks are older. Below is a chart of this phenomenon taken from A. R. Gregory "Rock
Physics in Seismic Interpretation," in Charles Payton Ed. Seismic Stratigraphy applications to hydrocarbon Exploration, AAPG Memoir 26, p. 19
Please explain why rocks which are older have a faster velocity, are more compacted, are more lithified and are harder?
