对云南大平掌铜多金属火山岩型块状硫化物矿床的矿石矿物和火山岩围岩的Ｓ、Ｐｂ同位素及脉石矿物、硅 化岩、硅质岩等的Ｈ、Ｏ同位素地球化学特征进行了研究，认为矿床中大多数硫来源于热液对火山岩的淋滤，或直接 来源于火山喷气作用；矿石铅与火山岩铅属同一来源，且以富放射性成因铅为特征；成矿流体可能主要来源于深循环的海水与岩浆水的混合流体，而大气降水参与的可能性很小。
The H, O isotope geochemical characteristics of S, Pb isotopes, gangue minerals, silicified rocks and chert of ore minerals and volcanic rocks in the Dapingzhang Cu polymetallic volcanic massive sulphide deposit in Yunnan Province were studied. It is believed that most of the sulfur in the ore deposit comes from the leaching of volcanic rocks by hydrothermal fluids or directly from volcanic eruptions. Lead from lead ore belongs to the same source as lead from volcanic rocks and is characterized by rich radiogenic lead; the ore-forming fluids may come mainly from deep Circulating seawater and magma water mixed fluid, and the possibility of participation in atmospheric precipitation is very small.
