摘要: 满总金铅银多金属矿床产于三缅村岩浆弧内，与满总单元中细粒角闪黑云二长花岗岩、谢巴组火山岩关系密切，围岩岩石化学、地球化学特征对成矿较为有利。据围岩特征及矿体中黄铁矿的热声测试和硫、铅稳定同位素测试成果分析，该矿床为花岗岩浆中温热液成因类型。Abstract: The Manzong gold lead silver polymetallic deposit occurs in the Sanmiancun magma arc in Tibet and is closely related to medium and fine grained hornblende biotite monzogranite of the Manzong unit and volcanic rocks of the Xieba Formation.The chemical and geochemical characteristics of the host rocks are favorable to mineralization.According to the characteristics of host rocks and thermosonimetric analysis of pyrite from orebodies with the BRC 1 type thermosonimeter,coupled with sulfur lead stable isotopic study,it is considered that this deposit is a mesothermal deposit associated with granitic magma.
