All showed evidence of mantle tissue nucleation only; the presence of a bead, whether shell or a tissue-nucleated FWCP, would be identifiable by distinctive features seen in the X-radiograph."
About two years ago, this same subject was debated on this forum. I'm not sure where it is but if you do a search, you'll probably find it. In my opinion, it was one of the best discussions held on P-G. |
Thank you for the citation of the GIA study, Gail! I tried to find P-G posts which specifically addressed Ward's remarks, but failed to find what had I hoped for.
I wanted to find a post saying, "Ward was wrong.", and information about definitive studies disproving his statements. You and Jeremy provided those today, and I'm relieved.
Thanks!
