The Granitization Problem

Abstract

The invaluable Presidential Addresses by Professor H. H. Read, entitled “Meditations on Granite”, Parts I and II, read to the Geologists’ Association in 1943 and 1944, seem to have aroused a great deal of interest in petrological quarters, more especially as these “meditations” are painted against the lively background of the historical development of ideas embracing a whole century and a half. Professor Read’s “meditations” are the more remarkable since they lead him to conclusions almost diametrically opposed to those propounded by Professor P. Niggli in an address delivered to the Zürich Geological Society at the February meeting of 1942, although both reviewers rely on about the same scope of historical “evidence”.
