| 摘 要： | 巴勉金矿床位于老挝乌多姆赛省西北部,该地区地质环境复杂,成矿条件优越。通过开展1∶5万地质测量及槽探工作,在巴勉金矿区发现了6条含金石英脉。根据本次调查和研究认为,巴勉金矿床是受叠加在韧性剪切带之上的脆性剪切带控制,矿床和韧性剪切带没有成因和时间关系,而只有间接空间关系,巴勉金矿床为"剪切后期"的热液矿床。

| Abstract: | Laos is located in the central north part of the Central South Peninsula,Southeast Asia.Bamian Gold Deposit is located in northwest of Oudomxay Province,Laos,and has complex geological environment and favorable metallogenic conditions.6 gold ore veins are found in Bamian gold district by carrying out 1 ∶ 50 000 survey and trenching.According to the investigation and study,the Bamian Gold Deposit is controlled by the brittle shear zone superimposed on the ductile shear zone.The deposit has no causation and time relationship with the ductile shear zone other than an indirect spatial relationship.Bamian Gold Deposit is a post-shearing hydrothermal deposit. |
