安徽巢湖马家凹铁金矿化特征与找矿前景
|
摘要
马家凹矿区区域上位于郯庐断裂带内,矿区出露地层为浮槎山岩组、大横山岩组、双山岩组、西冷岩组以及第四系,岩浆岩发育,构造变形强烈,主要构造变形为韧性剪切带,呈北东向展布。文章通过分析区域地质背景和矿区地质特征,结合钻探和槽探采集样品并分析结果,研究发现马家凹矿区铁矿化带3条,金银矿化带3条,因此该区具有良好的铁金找矿前景。
Regionally,the Majiawa ore district lies in the Tan-Lu Fault zone and is outcropped with the Fuchashan formation complex,Dahengshan formation complex,Shuangshan formation complex,Xileng formation complex and Quaternary system,where magmatic rocks are developed,and structures are highly deformed substantially as ductile shear zone trending NE.By analyzing regional geological setting and ore district geological features,combined with drilling and trenching samples and their analytical results,this paper found 3 iron mineralization belts and 3 Au-Ag mineralization belts showing good prospect for exploration of iron and gold in the ore district.
