摘要: 在西藏１∶２０万松冷幅、竹瓦根幅区域地质调查中，对左贡县桂亚拉地区发现的岫玉矿的地质特征、矿床特征、岩石、矿物和地球化学特征研究表明，雄恩错组的白云岩受岩浆热液作用形成的岫玉，为研究西藏非金属矿床成矿规律和构造演化及寻找玉石提供了新的基础资料。对岫玉与致密块状质纯的白云岩资源提出了综合开发利用的建议。
Abstract: During the 1∶200 000 regional geological survey of the Songleng and Zhuwagen Sheets, Tibet, the author studied the geological mineral deposit, petrological, mineralogical, geochemical characteristics of serpentinic jade in the Guiyala area, Zogang county, which indicates that serpentinic jade was formed by the action of magmatic hydrothermal solutions on the Xiongen Co Formation dolomite. This study has provided basic data for the research on the tectonic evolution and metallogeny of nonmetallic mineral deposits as well as search for gemstone jade in Tibet.
