Abstract
Analytical electron microscopy of phyllosilicates in a slate reveals marked differences in the composition of grains in different microstructural sites. These chemical variations illustrate that realignment of phyllosilicates during cleavage development is accompanied by the growth of new grains with compositions stable at higher metamorphic grades. The growth of new grains can be related to both recrystallization and crystallization processes which are controlled by the deformation mechanisms involved in slate development.This publication has 0 references indexed in Scilit:
