福建安村矿区寻找隐爆角砾岩矿床的探讨

Discussion on Searching for the Latent Explosion of Breccia Mineral Deposit in Fujian Ancun Mining

安村金矿区处于华南褶皱系闽东断拗带的周宁-华安断隆带中段。矿体成矿作用与断裂构造密切相关,矿体受北东、北西断裂带控制;围岩蚀变以硅化、绢英岩化、黄铁矿化最为重要。文章阐述了区域成矿地质背景、西乾金铜矿矿床地质及构造特征和成矿规律,分析了在安村金矿区寻找隐爆角砾岩矿床的可能性,对进一步寻找隐爆角砾岩型矿床方向进行探讨。

The Ancun gold mining areas is in the South China fold system Fujian fault-depression zone Zhouning- Hua-off middle lung zone. Ore mineralization is closely related with the faults, and the ore bodies in the control of the North East, North-West fault zone. The wall-rock alteration taket the silicifieation,sericite rock-oriented and pyrite as the most important. This paper has introduced the regional metallogenic geological setting,the West dry gold and copper deposits in the geological and structural features and mineralization law, analyzed the possibility of hidden breccia deposits in Aneun gold mining for further search for hidden breccia deposit.
