| 摘 要： | 对研究区变质岩的岩石学、地球化学研究表明,金水口群中-深变质岩原岩的为一套以火山岩为主的火山-沉积组合。火山岩主要为晶屑凝灰岩、岩屑凝灰岩、角砾凝灰岩、凝灰质砂岩等,属钙碱性岩系。沉积岩为泥灰岩。火山岩构造环境应属活动大陆边缘。

| Abstract: | The examination of petrology and geochemistry of the metamorphic rocks from the Sansegou Pb-Zn mining district in Dulan,Qinghai has mirrored that the protolith of the Jinshuikou Group mesometamorphic to hypometamorphic rock series are assembled by a succession of volcanic-dominated volcanic-sedimentary associations containing volcanic rocks,volcanic rocks intercalated with sedimentary rocks,and sedimentary rocks.The volcanic rocks consist of crystal tuff,lithic tuff,breccia tuff and tuffaceous sandstone,ind... |
