The biometallogenesis system of Jinya gold deposits consists of the following procedure: pre-concentration of gold and metallogenic matter in living organisms in Luodian-Danchi rift depositional basin; solution, absorption and concentration of metallogenic matter in organic matter and organic thermal fluid generated from organisms during lithogenesis; migration of gold and metallogenic matter in organic fluid from basin to Lingyun underwater carbonate platform and concentration at its boundary convex (palaeo-blind-mountain) during basin compaction ; metallization due to depth thermal fluid making organic fluid thermal degradation and forming new fluid which riches in gold and sulfur, and the fluid migrating upward and depositing in upside ore-controlling structures because of absorptions by organic carbon and atc.
通过研究金牙金矿作用的生物成矿系统内容为:在早、中三叠世罗甸—丹池裂谷盆地接受沉积时,生物对金等成矿物质就存在预富集作用;在成岩过程中,生物转化为有机质及有机热流体,对生物及沉积物中的金等成矿物质存在溶解、萃取、富集作用;在盆地压实成岩作用中,盆地中有机热流体向凌云水下碳酸盐台地运移,并在台地边缘外凸部位集中,此过程流体携带大量成矿物质,对金等成矿物质存在迁移集中作用;深部热流上侵使有机流体发生降解和释放金的热作用、形成高含金的有机热液,含金热液上移在构造通道中沉积并被有机碳再次吸附,最终形成金矿床,对金存在成矿作用。
