枞阳县陶家巷工区找矿潜力分析

Analysis of ore-prospecting potential in the Taojiaxiang mining site, Zongyang County

本文对枞阳县陶家巷工区成矿地质特征,物化探特征,地球化学特征,矿化蚀变特征等进行分析,研究显示区内成矿元素Cu、Pb、Zn等含量高于地壳背景值,断裂构造发育,断裂带内铜矿化、硅化等明显。断层发育,NE向断层发育,多以硅化带形式出现。裂隙发育,具不同程度的硅化高岭土化,局部充填有褐铁矿化脉。陶家巷-高庙山低缓异常带、方家湾地存在重磁同高异常,与已知矿化含铜破碎带重合。结果表明,陶家巷大刨山铜矿深部及外围、城山岩体与围岩接触带、夏家井、方家湾、五印庵-团山小学和高庙山具有较好的找矿潜力。

In view of geological, geophysical, geochemical and mineralized alteration features of the Taojiaxiang mining site in Zongyang County, this paper found that Cu, Pb and Zn contents are remarkably higher than the background val- ues, fracturing structures are developed and host marked copper mineralization and silication. The NE faults are devel- oped, mostly in the form of silication zone. Rifts are developed with varying degrees of silication and kaolinization, lo- cally filled with ferritized veins. The Taojiaxiang-Gaomiaoshan low gentle anomalous belt and both high gravitational and magnetic anomalies in Fangjiawan overlap with the known mineralized copper-bearing fracture zone. The results in- dicate good potential for ore prospecting in depth of the Dabaoshan copper mine and the periphery in Taojiaxiang, the contact between the Chengshan intrusion and wall rock, Xiajiajing, Fangjiawan, Wuyinan-Tuanshan Primary School and Gaomiaoshan.
