摘　　要：通过对青海省格尔木市郭勒木德镇晶质石墨矿含矿特征、岩石地球化学特征以及成矿环境的分析,查明晶质石墨矿赋存于早元古代金水口岩群白沙河岩组的大理岩段与加里东期岩浆接触部位;大理岩具有构造多期叠加、变形强烈的特征。晶质石墨矿具有层控后期热液变质的特征,具有很好的成矿环境和找矿前景。Based on the analysis of characteristics of ore bearing rocks, geochemical characteristics and metallogenic environment of crystalline graphite mine at Guolimude, Golmud, Qinghai, we found that the crystalline graphite deposit occurred contact site in marble and Caledonian magmatic Paleo- proterozoic Jinshui port group Baishahe rock group. Marble has a character of superimposed and de- formation. Crystalline graphite deposit has characteristics of stratabound late hydrothermal metamor- phism, mineralization environment and ~ood nre nraanort~
