| 中文摘要: |
| 沟里地区金矿床主体位于昆中Au成矿带之东段,也处于东昆仑南坡构造带之东段,经历了多期次的扩张-收缩及俯冲造山作用,形成了以Au、Ag、Pb、Zn、Cu、Co、Ni、Fe等为主金属矿产富集区。文章在沟里地区金矿成矿规律研究的基础上,通过成矿时代,金成矿与构造、岩浆岩、变质岩及围岩蚀变的关系分析,总结了青海省沟里地区金矿床成矿地质背景,对沟里地区金矿床的成矿地质背景有了较深入的认识,为后续找矿勘查工作提供指导意见。 |
| 英文摘要: |
| The main gold deposit in Gouli area is located in the eastern part of Kunzhong Au metallogenic belt, it is also located in the eastern part of the structural belt on south slope of the East Kunlun, where has undergone many periods of expansion-contraction and subduction orogeny before the formation of the enrichment zone for metals majored as Au, Ag, Pb, Zn, Cu, Co, Ni and Fe. Based on the study of gold mineralization regularity in Gouli area and analysisi on the relationship between metallogenic epoch and gold mineralization with the tectonics, magmatic rocks, metamorphic rocks and surrounding rock alteration, this paper is to sum up the metallogenic geological background of the gold deposits and make a deeper understanding on the metallogenic geological background of the gold deposits in the Gouli area of Qinghai, in order to provide guidance for the follow-up prospecting work. |
