摘要
以鄂东南铜铁金矿床为例,通过矿田、矿床构造地球化学研究,构造应力变形和岩石物理性质的讨论,阐述热液矿床成矿作用中物理条件变化对成矿热液迁移扩散和沉淀富集的影响,利用沉淀地球化学障的观点,尝试解决一个地区金属矿床产出,各种成因类型均受同一沉积建造控制,矿床规模与地球化学异常发育程度不对应等问题。
Through studies of tectonic geochemistry,tectonic stress deformation and physical properties of rocks of ore fields and mineraldeposits,the effect of variation of physical conditions in the metallogenic process of hydrothermal deposits on the migration-diffu-sion and precipitation-enrichment of metallizing hydrothermal solution are expounded in this paper by taking the Cu-Fe-Au de-posits in south-eastern Hubei as examples.From the point of view of geochemical precipitation barrier,an attemp has been madeto give explanation for problems on how an ore depodit is formed in a district,whether deposits of different genetic types are allcontrolled by a same sedimentary formation and why the extension of an ore deopsit and the degree of development of ageochemical anomaly are not in correspondance with each other.
