Daniel, >> Where does this claim of fractional-distillation in magmas come from? << Mea culpa. I went back and checked, and the fella who made this claim did indeed use the term "fractional crystallization." Sorry for the goof. So far, the tide seems to be flowing strongly against this claim that fractional-crystallization could mess up the isotope ratios, and thus mess up radiometric dating techniques. Jon W.
