摘要
本文利用电子探针分析了南极中山站和企鹅岛变质岩类岩石中主要造岩矿物(石榴石、斜长石、黑云母和角闪石)的化学组成,利用矿物地质温度计和各种成因判别图解,确定中山站变质岩类岩石的变质程度为高角闪岩相;企鹅岛变质岩类岩石的变质程度为低角闪岩相。
The chemical components of minerals(garnet, plagioclase, biotite and amphibole) from metamorphic rocks at the Zhongshan station and Penguin Island, Antarctic have been analyzed by electronprobe. With mineral geothermometer and different genesis distinguish diagrams, it was determined that the metamorphim degree of metamorphic rocks at the Zhongshan station was of high-amphibole face, and that at Penguin Island was of low-amphibole face.
