中文摘要: |
含金硫化物矿床在表生作用下,由于各种金属矿物的物理化学性质不同而形成了明显的分带特征.矿体中的物质成分发生分解构成了铁帽型金(银)矿床,其中金、银自上而下形成了次生富集矿体.本次工作采用了矿相鉴定、化学物相分析、原子吸收光谱、电子显微镜及电子探针等测试手段,在前人工作基础上进一步查明了安徽铜陵地区含金硫化物矿床的表生分带及金(银)的赋存状态. |
英文摘要: |
This paper presents the results of ore phase, chemical phase, atomic absorption, electronic microscope and probe. Based on this and the preceeding works supergene zonation of the Au-bearing sulfide deposits and Au-Ag mineralization are furtherly determinedUnder supergene processes of sulfide deposits, Tongling, Anhui Province metal minerals are disolved in different degree due to their different physiochemical properties. As a result, a zoned gossans are formed with gold ore bodies in the upper level and silver ore bodies in the lower level. |
