湖北省大冶市美人尖矿区金矿成矿条件分析及找矿规律浅析

Analysis of gold mineralization conditions and prospecting rules in Widow's peak mining area,Daye City,Hubei Province

美人尖矿区位于长江中下游成矿带中段,属于鄂东南矿集区腹地,该地区内共发现和圈定金矿体14个,低品位金矿体5个。根据其矿化类型、空间展布方向及分布位置,划分为美人尖金矿床和徐家山金矿点。矿化类型为微细粒浸染型和构造蚀变岩型,该区金矿成矿因素主要受地层、构造、侵入岩三重因素控矿,具有较好的找矿潜力。

The Meirenjian mining area is located in the middle section of the metallogenic belt in the middle and lower reaches of the Yangtze River,belonging to the hinterland of the ore concentration area in southeastern Hubei.There are 14 gold ore bodies and 5 low-grade gold ore bodies in the area.According to its mineralization type,spatial distribution direction and distribution position,it can be divided into Meirenjian gold deposit and Xujiashan gold deposit.The mineralization types are fine-grained disseminated type and structural altered rock type.The gold mineralization factors in this area are mainly controlled by strata,structure and intrusive rock,which have good prospecting potential.
