| 摘 要： | 西藏甲马铜多金属矿床的成因前人已提出了很多种观点。根据野外地质特征的观察 ,并结合矿区和区域岩矿石的微量元素、常量元素和稀土元素的分析与对比 ,作者认为该矿床的成因属于岩浆热液交代矽卡岩型矿床 ,推测其成矿时代为喜山早期。 |

| Abstract: | The Jiama copper-polymetallic deposit in Tibet is situated in the Gangdise structure-magmatite belt. It is a sole great style deposit in this region. Many scholars proposed several hypotheses for its genesis. Du Guangshu et al. thought the deposit is of sedimentation-exhalation genesis in 1998. This paper analysed geological characteristics, trace elements, major elements, mineral assemblage and rare earth elements of rocks and skarns in the Jiama ore district, indicating that as for the genesis the Jiama copper-polymetallic deposit belongs to magma hydrothermal metasomatic skarn deposits, and is Himalayan in age. |
| Keywords: | ore genesis skarns Jiama copper-polymetallic deposit Tibet |
