通过对长江中下游及邻区震旦系—早古生界内一些沉积叠加改造型锑-金矿床、银多金属矿床的物源及富集机制的地球化学研究认识到,在研究该类矿床的成矿作用时,不能仅仅局限在传统的认识和思维模式上,而是应该从更大的时、空域,用地球化学的思维去观察、去分析它们的“源、运、储”;该类矿床成矿的有利因素,除了矿源层的物源基础(成矿元素丰度,赋存形式)外,其决定因素还在于后期叠加改造作用对成矿元素浓集能力的高低和效率强弱的控制。
Through the study of the provenance and enrichment mechanisms of the Ag-Ag polymetallic deposits in the Sinian-Early Paleozoic in the middle and lower reaches of the Yangtze River and some adjacent sedimentary superimposed antimony-gold deposits, Should not be confined to traditional modes of understanding and thinking but should be observed and analyzed from a larger temporal and airspace perspectives using geochemical thinking to analyze their source, In addition to the provenance base of metallogenetic layer (ore-forming elemental abundance and occurrence pattern), the favorable factors of metallogenic ore-forming are the determining factors of the ore-forming element concentration ability and its efficiency control.
