火山岩型银多金属矿床是滇东南地区的重要矿床类型，矿床中疏的δ34S值分布于-6．9‰～+7．3％之间，并且呈波浪式分布；铅同位素组成以正常铅为主，并受异常铅的混染。硫、铅同位素具有相似的变化趋势。这些硫、铅同位素特征表明，该矿床成矿物质可能具有多种来源，除了直接来自玄武岩外，还有来自古海水硫酸盐和地层的贡献；该矿床的成因与玄武岩海底中心式喷发有密切的关系。
The volcanic-type silver polymetallic deposit is an important deposit type in southeastern Yunnan. The δ34S value of the deposit ranges from -6.9 ‰ to + 7.3%, and shows a wavy distribution. The lead isotope composition is composed of normal lead Lord, mixed by abnormal lead contamination. Sulfur and lead isotopes have similar trends. These sulfur and lead isotopic characteristics suggest that the ore-forming material of this deposit may have multiple sources, in addition to being derived directly from basalts, as well as from sulfate and formations in pale-seawater; the genesis of this deposit is closely related to basal eruptions of basalts relationship.
