摘要
根据对与贵州碳酸盐建造中的汞锑砷金矿床成矿机制有关的地质信息的辩证分析和这四种成矿元素地球化学性质的相似性及其在成矿作用中的紧密联系,通过运矿流体组成性质的推断,本文把汞锑砷金纳入统一的成矿地热系统来考虑,讨论了它们在运矿流体中的存在形式和成矿作用的一般地球化学机理。
According to dialectical analysis of geological information concerned about mineralization mechanism of Hg,Sb,As and Au ore deposits in carbonate formation in Guizhou,the author considers that this type of ore deposits possesses basically similar and general geochemical mineralization mechanism and that the ore - transporting fluids are hydrothermal solution which richly contain not only chloride ions Cl-,but also bisulfide irons HS' and other reducing sulfide species according to inferences from compositions and properties of ore - transporting fluids . On the basis of similarities of geochemical properties of the four elements and close relationships between them in the ore -forming processes,this Paper regards the four elements as a unitary ore -forming system and deals with the geochemical mechanism of the existing form and mineralization of Hg,sb,as and Au inthe ore -transporting fluids.
