摘　　要：从成矿物质来源、矿床定位场所、矿物包裹体、有机岩石学、生物标志化合物等几方面论述了兰坪金满铜矿床的改造成因证据，得到矿床产出于花开左组地层、富有机质暗色板岩与层间破碎带叠加处，改造有机质来源于深部、热演化程度较高等认识。Some evidnces for transformed genesis of Jinman copper deposit in Lanping, Yunnan were collected based on studies of origin of ore-forming material,located position of ore deposit, mineral inclusion, organic petrology, and biomarkers. The results showed that the copper deposit occurs at the superimposed part of organic matter-rich melasateand interlayer fracture zone in Huakaizuo Formation; transformed organic matter is from deep stratum and its maturatiom level is higher etc.
