| 中文摘要: |
| 铜陵新桥铁帽型金矿床赋存在硫化物矿床氧化带中。本文在论述该矿床氧化带形成条件基础上,根据地球化学资料统计结果,对矿床氧化带进行了剖面分带,并简述了各带地质、地球化学特征。研究表明:新桥铁帽型金矿床在氧化带中成矿,是由于地面抬升,地下水位下降,氧化带物化环境发生变化,金(银)等成矿物质不断氧化、分解、迁移、富集的结果。 |
| 英文摘要: |
| Xinqiao Gossan gold deposit is located in oxidized zone of a sulfide ore drposit. On the basis of formation analysis of the oxidized zone sub-zones are recognized by statistical resullts of the geochemital data about the zone and the geology and geochemistry for sub-zones are described. Xinqiao gold deposit is formed in the oxidized zone by rise of the surface and the fall of the water table, change of physio-chemical condition within the oxidized zone, continuous ore material(including Au, Ag)dissolution, migration and concentration. |
