摘    要:大水沟独立碲矿床的直接赋矿围岩为低绿片岩相变质岩。前人认为其原岩为陆源碎屑岩。通过对该赋矿岩系的地质特征(包括岩相学特征与副矿物组合标型特征)、岩石化学特征、硅同位素地球化学特征和稀土元素地球化学特征(包括元素钪的地球化学特征)的研究,证明其原岩为分异程度较低的幔源拉斑玄武岩,并具有典型岩浆玄武岩的演化趋势。

关 键 词:地质  地球化学  赋矿围岩  独立碲矿床

Abstract:The host rocks of Dashuigou independent tellurium ore deposit are mainly green schist facies metamorphic rocks. The protogenic rocks of these metamorphic rocks were thought by the previous researchers to be terrigenous clastic sediments. The authors of this paper researched on the geological characteristics including the occurrence, the petrography and the accessory minerals of the host rocks, chemical composition, silicon isotopes and REE of the host rocks of Dashuigou independent tellurium ore deposit. On the basis of the study on the geological and geochemical characteristics of the host rocks, the authors of this paper concluded that the protogenic rocks are not terrigenous clastic sedimentary rocks, but tholeiite from the mantle.
Keywords:geological and geochemical characteristics  host rocks  independent tellurium ore deposit
