| 摘 要： | 长期以来，有关会泽铅锌矿床的Pb、Zn成矿物质来源问题存在较大的争论。作者从成矿金属元素地球化学特征、Sr和Pb同位素组成特征出发，全面阐述了会泽铅锌矿床的Pb、Zn成矿物质来源。指出：成矿金属则是来自多方面的，它不仅来源于从震旦系到二叠系碳酸盐岩地层，而且来源于基底岩石（如昆阳群）和峨眉山玄武岩。因此，成矿物质具有多源性。

| Abstract: | Chinese geologic technicians always haven＇t reached an agreement on the sources of ore-forming materials in Huize lead-zinc ore deposits for a long time. After systematically studying the geochemistry characters of ore-forming elements, Pb isotopic composition and Sr isotopic composition, this paper gives out the sources of ore-forming materials in these ore deposits. It suggests that the ore-forming metal elements such as Pb and Zn, don＇t only origin from the carbonate strata of all the epochs from Sinian to Permian period, but also from Emeishan basalt and the basement rocks such as KunYang Group. So, they are multi-sources. |
