Abstract:

在东喜马拉雅构造结南迦巴瓦岩群中,石榴辉石岩呈透镜状产于麻粒岩相变质的长英质片麻岩和泥质片岩之中。石榴辉石岩主要由富铁铝榴石的石榴子石和透辉石组成,含少量的金红石、榍石和石英,不舍斜长石和角闪石,是榴辉岩相高压变质作用的产物,其原岩相当于基性-超基性层状侵入体中的辉长岩。在高压岩石快速抬升的过程中叠加了麻粒岩相和角闪岩相退变质作用。石榴辉石岩峰期变质作用的温度和压力条件是800-900℃和2.6-2.8GPa,变质时代可能为50Ma。本研究成果,以及超高压变质岩在西喜马拉雅构造结和榴辉岩在珠穆朗玛峰地区的存在,表明整个喜马拉雅造山带,从西构造结到东构造结,都经历了古近纪的高压、超高压变质作用,证明印度板块向欧亚板块之下的俯冲深度至少达到了80-100km。
