These books contain an exhaustive study of radiometric dates that do not fit the results evolutionists expect. Anyway, to me it seems unlikely that this chain of events would occur. I would have been perfectly happy to have an assumption of my final time deduced from the time for that first metres.

Mechanism of uranium crystallization and falling through the magma We now consider in more detail the process of fractionation that can cause dating profile good examples to be depleted at the top of magma chambers. I have no doubt that those who want to believe in an old earth will be able figure out a way to keep the overall story of problem with radiometric dating of rocks the same, regardless of how important this effect turns out to be, if that can even be determined to any reasonable precision.

Another problem with isochrons is that they can occur by mixing and other processes that result in isochrons yielding meaningless ages. Since fractionation and mixing are so common, we should expect to find isochrons often. Radioactive decay would generate a concentration of D proportional to P.
