摘　　要：黄狮涝山金矿床为一铁帽型金矿床，其形成具复杂演变史。笔者通过野外观察和室内综合研究，认为矿床形成经历了三期成矿作用，其中第一期喷气沉积成矿作用和第三期风化淋滤成矿作用最为重要，是矿床两个主要成矿期，第二期热液叠加成矿作用对矿床形成有一定贡献，但不具主导地位。最后，笔者讨论了风化淋滤过程中金的富集规律并指出了形成此类矿床的地质－地理条件。The Huangshilaoshan deposit is a gossan type gold deposit that has experienced a complex history of evolution,Field observation and laboratory work reveal that the formation of the ore deposit underwent three phases of mineralization,namely exhalative sedimentation,hydrothermal superimposition and weathering-leaching,of which the first and the third phases were two major ore-forming periods and the second phase made less important contri-bution,Finally,the authors discuss the enrichment regularity of gold in theweathering-leaching process and the geological-geographical conditions for theformation of this kind of gold deposits.
