摘要
研究了云浮硫铁矿床的成矿特征及大地构造演化史,认为赋存于变质岩学中的该矿床,其特征非单一成因所能解释,与火山喷发有关的沉积成矿,井受到后期变质和热液的叠加、富化、改造,成矿物质的多来源、多成矿方式和多大地构造阶段成矿是其多因复成成矿的主要成矿模式.
In this paper,the metallogenic characteristics and geotectonic evolution history of Yunfu pyrite deposit have been discussed.It is concluded that the deposit is char- acteristic of polygenetic and compound ore deposit and its origin can not satisractorily be explained by the mono-factor metallogenic model.So the author suggest a new metallogenic model:multi-source of ore-forming elements+multi-ore-forming processes+tectonic multi-stage mineralizations.At first,sedimentary mineralization,caused by the volcanic activities,occured.Then the deposit underwent later metamorphism and hydrothermal metasomatism and was enriched.
