摘要
澜沧老厂银铅铜矿床成矿受裂谷扩张、火山－沉积－后期热液等成矿作用控制。火山机构、地层岩性、有利构造、燕山期花岗岩侵入与成矿有密切关系，并控制矿床、矿体的产出。多期同位岩浆活动带来的多期同位成矿作用是本区形成大富矿的特点。提出了矿区找矿新地段。
The Laochang AgPbCu deposit is controlled by rift spreading and volcanicsedimentaryhydrothermal activities. The Metallogenesis shows close relation to apparatus, lithology of strata, structure and granite which control the occurrence of the deposit and ore bodies. It is characterized by the form of bonanza under isospatial mineralization at multistage in response to multistage isospatial magmatism. Finally, the prospecting location for undiscovered ores was selected.
