| Ore Deposit Characteristics and Metallogenic Model of the Maoping Pb-Zn Deposit in Wumengshan Mountainous Area, Yunnan Province |
| 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. |
