摘　　要：对云南白牛厂超大型银多金属矿床的地质、地球化学特征及矿床形成的长期性及多阶段性的研究认为:白牛厂银多金属矿床是热水沉积—叠生成因矿床,早期呈现寒武纪的热水同生沉积成矿作用,晚期为燕山期花岗岩浆热液成矿作用。该矿床是热水沉积成矿作用与岩浆热液成矿作用叠加成矿的产物。On the basis of the geological and geochemical characteristics of the metallic deposit and its longterm multi-staged mineralization, the authors consider that the Bainiuchang silver-polymetallic deposit is a hotwater in deposit - diplogenetic deposit. The Cambrian hot-water syngenetic sedimentary ore-forming process occurred in the early stage, while the Yanshanian granitic magma hydatogenesis in the later stage. The deposit was produced by superimposition of the hot-water sedimentary mineralization and magmatic hydatogenesis.
