| 摘 要： | 通过对呼鲁斯太幅和古拉本幅的１／５万区域地质调查工作，对该地区太古代贺兰山群中－高级变质岩中早元古代花岗岩进行了岩石谱系单位的划分和填图。在此基础上，从花岗岩的地质学、岩石学、岩石化学和地球化学等方面进行了较系统的详细研究，把早元古代花岗岩划分出７个单元，并将其中的５个单元归并为两个超单元。

| Abstract: | Through the 1:50000 regional peological surveying in Hulusitai and Gulaben,granite in middle-highmetamorphic rocks of the Helanshan Group is mapped and Classified using the granitoid lithodimic.In this paper,the author systematically studied the geology,Petrology,Petrochemistry and geochemistry of early Proterozoic granides,and divided them into 7 units.5 units are grouped into two superunits. |
