高喜马拉雅地区广泛分布着一套结晶岩系,它是由前寒武系铁铝榴石-闪岩相的巴罗型区域变质岩系、混合岩和第三纪花岗岩组成。在我国境内聂拉木一带出露宽度达50公里。应思淮(1973)把这套岩系命名为珠穆朗玛群,张旗(1979)把它叫做聂拉木群。对于其中区域变质岩的变质带划分,存在不同的看法。本文比较详尽的研究了喜马拉雅中段(包括聂拉木,吉隆区和珠峰地区)和雅鲁藏布江大拐弯地区变质岩系中的石榴子石
A series of crystalline rocks are widely distributed in the Greater Himalayas. They are composed of Barrow-type metamorphic rocks, mixed rocks and Tertiary granites of the Precambrian enalism-amphibolite facies. Nyalam area in our country exposed width of 50 km. Should think Huai (1973) to the rock series named Everest group, Zhang Qi (1979) called it Nyalam group. There are different opinions on the metamorphic belt division of the regional metamorphic rocks. In this paper, a detailed study of the mid-Himalayan (including Nyalam, Geelong and Everest region) and the Brahmaputra metamorphic rock metamorphic rock garnet
