摘要
厄立特里亚位于东非造山带的阿拉伯-努比亚地盾的中部,区内泛非期各类侵入岩、火山岩广泛发育,是重要的金铜找矿潜力区.Ewanet金铜矿位于Asmara北西向构造变形带南端,区内断裂构造发育,断裂构造是区内重要的导矿、控矿容矿因素,它不仅是矿液运移的通道,还为矿液储存提供了有利的空间.通过对矿床成矿地质背景、围岩蚀变及找矿标志研究,基本查明了该矿床成因,研究结果为东北非金铜矿找矿提供了较好借鉴.
Abstract
Eritrea is located in the central part of the Arabian Nubian Shield in the East African Orogenic Belt.Various intrusive and volcanic rocks of the Pan African period are widely developed in the area,making it an important potential area for gold and copper exploration.The Ewanet gold and copper deposit is located at the southern end of the Asmara northwest trending tectonic deformation zone,with well-developed fault structures in the area.Fault structures are important ore-forming and controlling factors in the area.They not only serve as channels for mineral fluid migration,but also provide favorable space for mineral fluid storage.By studying the geological background,rock alteration,and prospecting indicators of the ore deposit,the genesis of the deposit has been basically identified.The research results provide good reference for the exploration of gold and copper deposits in Northeast Africa.
