摘 要: 论述了老厂矿床的大地构造环境、 矿床地质地球化学特征、喷流岩特征和成矿温度，划分了矿化期和矿化阶段，认为老厂矿床应属澜沧裂谷(断拉谷)中海底火山喷流沉积型并迭加隐伏岩浆热液改造型矿床，建立了“三层楼” 成矿模式。对今后找矿勘探工作具重要的理论指导意义。

Abstract:The geotectonic setting, the geology of ore deposits, geochemical and sedex rock characters and metallogenetic temperature were studied, as well as metallization phase and stages of mineralization of Laochang ore deposits. It was considered that the Laochang ore deposits should be contained in the submarine volcanic sedex-reformed deposits in Lancang rift. The "three-storey building pattern" metallogenetic model was established, which has important theoretical and guiding significances for the prospecting in future.
Key words: massive sulfide deposits genesis of deposit metallogenetic model
