Basic characteristics and genetic analysis of glaucophane schist in Subugeta, Inner Mongolia
摘要
Abstract
The studied glaucophane schist is in the Ordovician Halahahe Formation of Subugeta, Inner Mongolia, and there are a variety of rock assemblage types. According to the optical characteristics and EMP analysis, the authors have come to the conclusion that the glaucophane schist is a kind of ferriglaucophane in the study area. The topomineral assemblage of glaucophane schist is characterized by glaucophane + epidote + actinolite + phengite + sphene. The schist was cemented and recrystallized by shaly clasolite, and the formation environment of native rock was the marginal-sea basin of the continent. The metamorphic origin belonged to the regional low-temperature/middle-high pressure dynamic metamorphism related to plate movement.关键词
