摘    要:安徽省大别山区含柯石英榴辉岩主要分布在太湖县、潜山县及霍山县一带。根据其地质特征、物质成分和矿物组合等可分分为三种类型:赋存在蛇纹岩、滑石片岩中,具斜方辉石岩外壳的榴辉岩;赋存在黑云斜长片麻岩中的榴辉岩;赋存在造辉透门大理岩中的榴辉岩。主要矿物组合为石榴石、绿辉石、柯石英及副矿物金红石和榍石。它属于华中高压变质带的一部分。

关 键 词:榴辉岩  柯石英  安徽省

Abstract:The coesite-bearing eclogites in Dabie district mainly occured in Taihu county, Qianshan county and Hueshan county. According to the geological characteristics, composition and mineral associations of coesite-bearing eclogites, we can divide them into three types, i.e., 1 )eclogites occured in serpentines and talc-schists as lenticle or bed-likes 2 ) eclogites occured in Bi-Pl-gneiss as bed; 3) eclogite occured in Di-Tr-marbles as mass or lenticle. The main mineral associations in eclogites are garnet, omphacite, coesite and accessory minerals (rutile and sphene).The eclogites are a part of high-pressure metamorphic belt in central China.
Keywords:eclogite   coesite   Anhui Province
