| 摘 要： | 青海南部三江北段构造成矿带经历了复杂而完整的多期次复合造山及叠加改造地质构造过程,导致复杂丰富的成矿演化,发育一系列大型、超大型的铜、金、铅锌等金属矿床。研究认为,目前青海三江北段主要的成矿系统为:与三叠纪火山喷发作用有关的铁、铜、铅、锌、银等成矿系列,与新生代浅成侵入岩有关的钼、铜、铅、锌多金属成矿系列,与新生代有关的热液叠加改造型铅、锌多金属成矿系列。这些成矿系统代表了区域矿矿产资源进一步勘查的方向。

| Abstract: | Northern Sanjiang metallogenic tectonic metallogenic belt in sourth part of Qinghai Provience had experienced multi-stage complex and complete composite orogenic and transformation geoglgical processes, which have cause rich and complex metallogenic evolution and grow a series of copper, gold, lead, zinc and other metal deposits. In this paper, research suggests that the main ore-forming system of Sanjiang metallogenic ore belt inclued Fe, Cu, Pb, Zn, Ag metallogenic series are related with Triassic volcanic and Mo, Cu, Pb, Zn mineralization series are related with Cenozoic hypabyssal intrusive rocks. Pb, Zn polymetallic metallogenic Hydrothermal transformation series are related with Cenozoic magmatic rocks. These ore-forming systems represent the mineral resources exploration direction. |
