摘要
安徽宁国石口金矿位于钦杭成矿带北东段,是最近新发现的金矿床。在野外地质调查和室内综合研究的基础上,对石口金矿的地质特征及控矿因素进行研究。结果表明:石口金矿矿体主要产于断裂破碎带中,呈透镜状、似层状,矿石以断裂角砾岩型为主。晚寒武世—早奥陶世西阳山组泥质灰岩、早奥陶世印渚埠组泥岩是控矿地层,NW向张性断裂是最主要的容矿构造。石口金矿NW向断裂具有较好的找矿潜力,该金矿的发现为钦杭成矿带金矿找矿勘查提供了新思路,可进一步扩大该区找矿空间。
The Shikou gold deposit in Ningguo City,Anhui Province,a newly discovered gold deposit is tectonically located in the northeastern section of the Qinzhou-Hangzhou metallogenic belt.On the basis of field geological investigation and indoor research,this study analyzed geological characteristics and ore-controlling factors of the Shikou gold deposit.The study shows that ore bodies occur mainly in faulting zones as len and stratoid forms and ore type is dominantly faulting breccias.The argillaceous limestone of the Xiyangshan Formation and the mudstone of the Yinzhubu Formation are the main Au-bearing ore sequences and NW-trending tensional fault is the major ore-hosting structure.And the NW-trending tensional fault in the Shikou gold deposit is of better potential for gold deposits.Therefore,discovery of the Shikou gold deposits provides a new direction for gold exploration and target area for gold exploration can be further expanded.
