| 中文摘要: |
| 青海东昆仑地区近年来沟里金矿、五龙沟金矿等老矿区取得了新进展和新突破，到继续开发，黑海北等多个新矿区（点）取得新发现。本文分析了区域成矿条件和典型矿床，总结出东昆仑地区金矿床的主要控矿因素，认为该地区金矿床主要形成于海西期-印支期，其次为加里东期；岩浆活动为金矿床形成提供了成矿流体和成矿物质来源；北西西-北西向构造及次级构造控制了金矿体的展布。成矿分析表明，东昆仑地区具有良好的金矿床成矿潜力与找矿前景。 |
| 英文摘要: |
| Recent years have seen continued development of the old gold deposits, such as Gouli and Wulonggou, as well as discovery of many new gold deposits including Heihaibei in the East Kunlun region of Qinghai Province. This paper analyzes the metallogenic conditions and typical deposits and summarizes the key ore-controlling factors in this area. It is considered that the Late Variscan to Indosinian is the main mineralized period of gold deposits in East Kunlun, followed by Caledonian. The magmatism provides ore-forming fluids and material sources for the formation of gold deposits. NWW-NW structure and secondary structures control the distribution of gold orebodies. Metallogenetic analysis suggests that there exist good metallogenetic conditions and prospecting potential for gold deposits in the East Kunlun region. |
