| 摘 要： | 云南姚安金矿床是滇西北地区与喜马拉雅期富碱侵入岩类有关的典型矿床之一.矿床成矿具有多期多阶段性，蚀变分带明显.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、成因上密切相关的关系.对矿床和相关富碱岩体（脉）金丰度值、同位素和稀土元素的研究表明，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，以上地幔或壳幔混合带为主.通过深入讨论岩体成岩与流体成矿之间的关系，反映了与富碱岩浆活动有关的金矿床在成因上具有复杂性.

| Abstract: | Yao'an gold deposit,located in Northwest Yunnan Province,is a typical deposit related to the Himalayan epoch alkali-rich intrusive rocks.The ore-forming process could be div ided into three epoches and five stages.There are several obvious alteration zones in the ore district.The occurrence of o re-bodies or ore-veins are closely r elated to the alkali-rich rock bodies /veins spatially,temporally and genetically.By researches on the gold content,is otopes and REE in different types of rocks,it is con cluded that the origin of the gold and fluid was not from the alkali-rich ro cks,but mainly from the depth of the earth(mantle or the mixing zone of mantle an d lower crust)The relationship between magmatic evolution and gold mineralization is further discussed. |
