| 摘 要： | 云南马厂箐（铜、钼）金矿床是滇西北地区与喜马拉雅期富碱侵入岩类有关矿床的典型代表之一。矿体（脉）的产出与区内富碱岩体（脉）具有空间上形影相随、时间上相近或稍晚、成因上密切相关的联系，蚀变分带明显，对矿床和相关的富碱岩体（脉）开展的金丰度值、同位素和稀土元素研究表明，富碱岩体本身并不是矿质的源地。成矿流体和主要矿质均源于地球深部，以上地慢或壳慢混合带为主。章进一步讨论了岩浆成岩与流体成矿之间的关系，反映了与富碱岩浆活动有关金矿床在成因上具有复杂性。

| Abstract: | The Machangqin Cu-Mo-Au deposit is a type deposit related to the Himalayan epoch rich-alkali intrusive rock. There are several obviously alteration zones in the ore district. The occurrence of orebodies or ore veins had intimate relationships with the rich-alkali rock-body (vein) in space-time and genesis. Based on the gold content in different type rocks, isotope and REE, it is concluded that the origin of the gold and fluid was not from the rich-alkali rocks, but mainly from the depth of the Earth or may be from mantle or the mixing zone of mantle and lower crust. The relationship between magmatic evolution and gold mineralization was discussed. |
