摘　　要：从历史-因果论出发，运用陈国达教授提出的多因复成成矿理论，对广东云浮硫铁矿的成矿作用重新进行了研究和解剖。首次研究并论证了矿床形成的裂谷背景，提出了本矿床是一种经历了晚元古代裂谷期海底喷流初始沉积，加里东期裂谷回返动力变质过程中的矿体塑性流动和剪切固态迁移集中富集（有混染了的变质热液的叠加），印支或岩浆热液叠加富化的多因复成矿床的新观点。From the viewpoint of historistic-causationist geotectonlcs and the polygenetic compound metallogenic theory advanced by Chen Guoda, the mechanism for the Yunfu pyrite deposit, Guangdong province, is Investigated. The pyrite deposit occurs in a Proterozoic rift and is a polygenetic compound deposit. The deposit has experienced the following processes:(A) initial precipitation during the rift stage of the Upper Proterozoic era, (B) plastic flow,shearing solid phase migration and concentration of pyrite during the dynamometamorphism stage of the Caledonian epoch, and (C) late superlmpositlon and reworking of magmatic hydrothermalism during the Indosinian epoch.
