| 中文摘要:云南乌蒙山区毛坪铅锌矿床是滇东北铅锌成矿带中重要的矿床之一。2010年以来, 中国地质调查局响应国家“十二五”和“十三五”脱贫规划, 开设了“乌蒙山区地质矿产综合调查”二级项目, 由成都地质调查中心负责实施。大调查的全面实施, 国家公益性基础研究的不断深入和商业性勘查的及时跟进, 使得云南乌蒙山区内实现了真正意义上的找矿突破, 从而助益于地方经济发展和国家脱贫战略目标。论文在前人资料和研究成果综述的基础上, 结合研究团队近年来的研究进展, 以毛坪铅锌矿最新发现的高温热液改造痕迹为契机, 在详细的野外地质工作基础之上, 重新系统总结了毛坪铅锌矿的矿床地质特征, 并借助于年代学、岩石地球化学和同位素地球化学, 从微量元素、H-O同位素、S同位素和铅同位素等方面提出成矿物质来源的新证据, 认为其至少存在2期成矿期次, 与其中一期成矿时代相近的黄龙组(C2h)地层为成矿提供了部分物质来源, 在此基础之上总结提出了毛坪铅锌矿的成矿模式。 |

| Abstract:The Maoping Pb Zn deposit in the Yunnan mountain area is one of the most important deposits in the northeastern Yunnan Pb Zn metallogenic belt. Since 2010, in response to the national “12th Five-Year” and “13th Five-Year” poverty alleviation plan, China Geological Survey has implemented the project of “comprehensive survey of geology and mineral resources in the Wumengshan mountainous area”, which was carried out by the Chengdu Geological Survey Center. The comprehensive implementation of large-scale investigation, the continuous deepening of the basic research on national public welfare and the timely follow-up of commercial exploration led to the real prospecting breakthrough in the Wumengshan mountainous area, thus helping the development of local economy and the strategic goal of national poverty reduction. On the basis of the summarization of the previous data and research results, and in combination with the research progress of the geological party in recent years, the geological features of the Maoping lead zinc deposit were systematically summarized based on the detailed field geological work, and the geological characteristics of the Maoping lead zinc deposit were systematically summarized with the aid of rock and isotopic geochemistry. The new evidence of metallogenic material sources was put forward from trace elements, H-O isotopes, S isotopes and lead isotopes. It is believed that the Huanglong Formation (C2h), whose formation age is similar to the metallogenic epoch, provided some material sources for mineralization. |
