【摘要】 青海省格尔木市五龙沟—金水口地区地层属秦祁昆地层大区——东昆仑—柴达木地层区。出露地层为古元古界金水口岩群、中元古界小庙岩组和奥陶系祁漫塔格群。其中金水口岩群为变质基底岩系,小庙岩组属似盖层沉积,祁漫塔格群为沉积盖层,新生代沉积了第四纪地层。文章对五龙沟—金水口地区地层分布特征进行了分析研究,为该区下一步的勘探工作提供必要的地质参考依据。更多还原

【Abstract】 The strata of Wulonggou-Jinshuikou area of Golmud City in Qinghai Province,belong to Qinqikun-East Kunlun-Qaidam strata area. The strata exposed are Paleoproterozoic Jinshuikou Group,Mesoproterozoic Xiaomiao Group and Ordovician Qimantag Group. The strata of Jinshuikou Group are metamorphic basement rocks,Xiaomiao Group are caprock-like deposits,Qimantage Group is sedimentary caprock,and Quaternary strata were deposited in Cenozoic. In this paper,the stratigraphic distribution characteristics of Wulonggou-Jinshuikou area are analyzed and studied. It provides the necessary geological reference for the next exploration work in this area.更多还原
