A preliminary study on the evolutionary characteristics of rare earth elements (REE) in granitoid rocks and their formation mechanisms in Xianghualing region, Hunan Province, China

Abstract

Recognized in the Xianghualing region, South Hunan are three major types of granitoids. i.e., biotite granite, zinnwaldite-albite granite and xianghuagite, which evolved from the same granitic magma, but were formed at different stages. These granitoid rocks constitute a complete magmatic evolutionary series.
