福建省德化县安村雷潭金矿床地质特征和找矿方向

Geological Characteristics and Prospecting Direction of the Fujian Dehua Ancun Leitan Gold Deposi

福建省德化县安村金矿位于闽中戴云山带中段的安村村,直距德化县北东18°约40km。矿区出露地层以上侏罗统南园组火山岩为主,侵入岩主要为燕山早期石英闪长岩和小脉岩,金矿床主要受北西向构造断裂带控制,矿体定位于其主构造与次一级构造,主断裂既为导矿构造,也是容矿构造。区内辉绿岩和闪长(玢)岩与成矿关系密切。本文基于前人工作的基础上,结合近几年矿山与地质队的勘查工作,对地质资料进行系统整理与综合分析,在此基础上指出下一步的找矿方向。

The Ancun gold deposit in Dehua County,Fujian Province,is located in the Middle Section of the Daiyun mountain belt in central Fujian Province,which is about 40 km away from the north east of Dehua County at 18°.The exposed strata in the mining area are mainly volcanic rocks of the Nanyuan formation of the Upper Jurassic,and the intrusive rocks are mainly quartz diorites and small dikes from the early stage of Yan Mountains.The gold deposits are mainly controlled by the NW trending structural fault zone,and the ore bodies are located in the main structures and secondary structures,the main fault is not only the ore-bearing structure,but also the ore-hosting structure.Diabase and Diorite(porphyrite)are closely related to mineralization.On the basis of previous work and combined with the exploration work of mines and geological teams in recent years,this paper makes a systematic arrangement and comprehensive analysis of geological data,and points out the direction of ore prospecting in the future.
