Statistical Studies of Zircon as a Criterion in Granitization


THE opposing views of magmatists and transformists have resulted in a heated controversy on the origin of granite, and a recent conference on this question held by the Geological Society of America1 has stressed the importance of criteria for distinguishing between granite formed in situ and granite formed elsewhere and intruded in new surroundings. It has been demonstrated repeatedly that criteria, formerly regarded as incontrovertible, are open to debate. Indeed, there do not appear to be any established criteria which both magmatists and transformists will accept as decisive.
