Why should the percentage of lead to uranium in zircon crystals (the key to ordinary uranium-lead, radiometric dating) depend on which geologic period they are found in?If most of the geologic column were created during Noah's flood, would it really matter whether a zircon crystal was found in Cambrian strata or Cretaceous strata, in Jurassic strata or Tertiary strata?One can hardly accuse these pioneers of evolutionary prejudice.Nearly a half-century would pass before Darwin's book, The Origin of Species, was published! With a half-life of only 5730 years, carbon-14 dating has nothing to do with dating the geological ages! Hovind is confusing the carbon-14 "clock" with other radiometric "clocks." The only thing in the geologic record which has anything to do with calibrating carbon-14 dating is the coal from the Carboniferous Period.Being ancient, the C-14 content has long since decayed away and that makes it useful in "zeroing" laboratory instruments. Hovind would take the trouble to do a little reading from something other than creationist publications he would not make such an outrageous statement.Evolution, working in tandem with geologic ages, can explain why we have index fossils, but evolution is needed to make the index fossils useful for dating strata.While we're on this subject, you might wish to know the odds of arranging the Precambrian era, the seven geologic periods of the Paleozoic (Cambrian, Ordovician, Silurian, Devonian, Mississippian, Pennsylvanian, Permian), the three periods of the Mesozoic (Triassic, Jurassic, Cretaceous), and the two periods of the Cenozoic (Paleogene, Neogene or Tertiary, Quaternary) in their proper order by pure chance.
The principle of faunal succession in the geologic record was established by direct observation as early as 1799 by William Smith.
Any kind of object clearly restricted to a specific point in the geologic column would do just fine.
If green dice were found only in the middle Ordovician strata, they would make excellent "index fossils." Evolution should be seen as an explanation of the faunal succession, a succession which was worked out long before evolution dominated the scene.
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.
