Would you please explain primordial polonium in granite. If the rock formed by slowly cooling, then there should be older halos in the rocks to, but then it would just be polonium, not primordial polonium. The fact the primordial polonium is there proves that the granite formed solid in less the 5 minutes.
primordial polonium can only exist for a few minutes, before it decays.

"Primordial polonium" in granite is a fiction created entirely by Young Earth Creationists, namely Robert Gentry, who is not a geologist. The only way it can be considered primordial is if you believe in a a young earth, otherwise as you say, it is just polonium. I am afraid this argument is entirely with the Creationists, as they are the only one who believe in this idea. Geologists don't use polonium as proof of the age of granites. I doubt that it is used by biologists to prove evolution either, as granite, polonium, and evolution are completely unrelated.

As for the older pleochroic haloes: they do exist. Any alpha emission from a radionuclide can form a pleochroic halo. Since polonium 212 is a daughter product of thorium, and thus results from the decay of uranium it can come along at any time.

I think you are confusing a debate entirely among Creationists for a scientific debate between scientists and Creationists. Gentry's argument is that the halos are evidence of primordial plutonium and therefor prove Young Earth existed. For Gentry to be correct he would have to prove first that the halos were only created by polonium (which he can't prove) and second that it was there when the granite formed (which he also cannot do). The simple answer is that since polonium can be found today, and it does have a short half-life in all of its nuclides, his argument is meaningless in proving a Young Earth.

The cooling of igneous plutons has nothing to do with evolution or evolutionists. You want to ask an igneous petrologist.

But I doubt that would help an ignorant, closed-mined, hate-filled person such as yourself. I hope you don't call yourself a Christian. Your profile is extremely un-Christian.
