Abstract

Albitization proceeds by a dissolution-precipitation mechanism. At shallower depth, dissolution of the parent K-feldspar is more rapid than the precipitation of albite, and rates of albite precipitation increase with depth, favoring pseudomorphic replacement of K-feldspars, Other factors that influence albitization processes are aNa+/aK+, permeability reduction, and surface-dissolution kinetics of the parent grain. -from Authors
