本文概要介绍我国第二次南极考虑队地质研究组,通过野外观察研究所取得的一些初步成果,其中包括将工作区火山地层细分为五个岩性地层组;对古火山喷发中心作了构造岩相学研究;地质图上圈定出广泛发育的次火山岩体,划分了由不同矿物组合所构成的蚀变类型;初步调查了地下水的含水层及其与淡水湖之间的补给关系。
This paper gives an overview of some preliminary achievements of the Second Antarctic Research Team of Geological Research Group in China through field observation and research, including the subdivision of the volcanic layer in the working area into five lithologic stratigraphic groups; the construction of the ancient volcanic eruption center The study of petrography shows that the widely developed subvolcanic rock bodies are delineated on the geological map and the types of alteration formed by different mineral assemblages are divided. The aquifer of groundwater and its supply relationship with freshwater lake are preliminarily investigated.
