Ratio used in carbon 14 dating
One would think that the flood sediments (gathered from the four corners of the old antediluvian world) and their associated igneous rock (formed during the flood) would all register very little radiometric age.At the very least we would expect random fluctuations if the radiometric methods were totally at sea.
(The principle of superposition was recognized as early as 1669 by Steno.) Reverend Benjamin Richardson and Reverend Joseph Townsend were a couple of early geologists involved in this work. Obviously, even Lyell was not pushing evolution at the time.(See Topic A1 for claims of bad dates.) Creationists, on the other hand, must explain to us how sediment and rock laid down in a mere year can yield such fantastic, orderly differences in radiometric ages.This poses a fatal problem whether one believes in the accuracy of radiometric dating or not!What does the Jurassic strata have that the Tertiary strata do not? Neutrinos penetrate the earth so easily that they would affect all strata more or less equally, to the extent that they affect anything at all.If rock type mattered then we would expect a zircon crystal's lead content to vary dramatically within the Cambrian or Cretaceous strata according to their local rock types. Cosmic rays, on the other hand, don't penetrate that far into the earth to begin with, so we can rule them out.
