Based on hundreds of thin sections from granite in China, this
book introduces metasomatic textures and their formation
mechanism in granite. It also proposes that metasomatic textures
can basically be classified into two patterns: hetero-oriented
replacement and co-oriented replacement, according to the
consistency of orientations of replacive and replaced minerals.
The hetero-oriented albitization of K-feldspar is quite distinct
from the co-oriented albitization of K-feldspar. They occur
separately without transition, although both are generally
referred to as albitization of K-feldspar.

This unique granite atlas uses a series of color microphotos
taken with a quartz plate under crossed polars to clearly
illustrate metasomatic mechanisms and superimposed metasomatic
processes. The origins of clear albite rim, intergranular swapped
albite, K-feldspathization, quartzification, muscovitization,
beryllization, myrmekite, small platy albite, perthitic albite,
K-feldspar megacryst etc. are comprehensively discussed and
explained. The book will appeal to teachers, researchers and
students involved in igneous and metamorphic petrology.
