tends to get ignored by the "mainstream" scientific community because of the implications

What implications? Are careers on the line?

I do not know of a specific refutation of Collins' claims by Gentry, but I can tell you that the vast majority of granitic rocks do not form by repeated cataclasis and recrystallization. Where you do see that happen, it is pretty evident and any first year (OK, second year) geology student should be able to recognize a migmatite, cataclastite or myrmekite in the field.

Gentry discusses that if there are fractures and permeabilities involved, then yes, you can move Uranium-bearing solutions or radon gas along the fractures and simulate the Polonium halo effect. Gentry's point all along, which Collins has obviously ignored, is that the Polonium halos form in the biotite crystals where there is no evidence of secondary fluid movement and indeed, no discernable fractures. Once again, where these do occur, they are pretty obvious. Even microfractures in something like biotite show up pretty well in thin-section under polarized light.

I'm not saying Collins' arguments are out to lunch, but, like so many evo arguments, he is building a strawman to poke holes in.
