| 摘 要： | 汞丹山凸起的麻粒岩类岩石可分为二辉麻粒岩、角闪二辉麻粒岩和紫苏混合花岗岩等。其主要矿物有斜长石(Anzb-34)、紫苏辉石、单斜辉石、普通角闪石、黑云母、条纹微斜长石、石英等。副矿物有磁铁矿、磷灰石、锆石、石榴石、金红石等。借助于多勃列佐夫(1971)的判别式,判别本区二辉麻粒岩类岩石属较低温的角闪麻粒岩亚相。按不同计算公式估算: 麻粒岩相形成温度为898.8℃、828.2℃、957.7℃;形成时的压力低于0.5GPa。

| Abstract: | The granulite facies rocks distributed on the Gongdan-shan uplift can be divided into twopyroxene granulite, hornblende two-pyroxene granulite, hypersthene migmatitic granite, etc.,with its essential minerals including plagioclasel (An26-34),hypersthene, clinopyroxene, hornbende, biotite, perthite-microcline, quartz, etc; whereas accessory minerals including magnetite, apatite, zircon, garnet, rutile, etc.By aid of Doblezov s discriminant(1971), the two-pyroxene granite in this area can be recognized as low... |
