北衙金多金属矿床地处西南三江特提斯造山带与扬子地台西缘的结合部位,区内资源丰富,成矿条件极其复杂。在北衙东部笔架山、桅杆坡以及北部芹河等矿段勘探发现大量似层状铅锌银多金属矿床。前人对新发现的似层状铅锌银多金属矿床缺乏系统研究和认识,矿床成因存在争议,邓军等人认为似层状铅锌银多金属矿床是斑岩热液成矿系统外带的产物(邓军,2012),本文通过野外地质观察,综合前人研究资料及硫化物矿石S、Pb同位素特征,探讨似层状铅锌银矿床的成矿物质来源及形成机
The Beiya Gold Polymetallic Deposit is located in the junction of the Three Tethyan Tethyan orogenic belt and the western margin of the Yangtze Platform in the southwest. The resources in the area are abundant and the metallogenic conditions are extremely complicated. A large number of stratiform Pb-Zn-Ag polymetallic deposits were found in the beacon sections of Beijia Mountain, Mast Slope, and Qinhe Area in the north of Beijiang. The predecessors lack of systematical research and understanding of the newly discovered stratiform Pb-Zn-Ag polymetallic deposit, and the genesis of the deposit is controversial. Deng et al. Think that the stratiform Pb-Zn-Ag polymetallic deposit is the outer belt of the porphyry hydrothermal mineralization system (Deng Jun, 2012). Based on the field geological observation and the previous research data and the S and Pb isotopic characteristics of sulphide ores, this paper explores the origin and formation of metallogenic materials in the quasi-bedded Pb-Zn-
