摘　　要：以勘查区找矿预测理论方法为指导,对铜绿山铜铁矿开展深入研究,确定湖北大冶铜绿山铜铁矿的成矿地质体为铜绿山石英二长闪长玢岩,成矿构造为北北东向马叫—铜绿山背斜、同向断裂及岩体与大理岩捕虏体的接触带,成矿结构面为岩体与大理岩接触面、褶皱轴向和层间滑脱面及岩体内裂隙面,并确定了成矿作用标志。基于此构建了铜绿山“三位一体”找矿预测模型并开展找矿预测,认为ⅩⅣ号矿体沿走倾向延伸以及铜绿山矿体沿走向向南延伸部位均具有较大找矿潜力,开展精准的矿体定位预测依赖于大测深地球物理探测方法和三维地质建模等技术手段。Take the theory of prospecting and prediction in exploration area as the guidance,this paper develops deeply study on Tonglvshan Cu-Fe deposit.The metallogenic geologic body of Tonglvshan Cu-Fe deposit is identified as Tonglvshan quartz monzonite-diorite porphyrite,the metallogenic structure is the NNE Majiao-Tonglvshan anticline,the synthetic fault and the contact zone between the rock mass and marble xenolith.The metallogenic structure surface is the contact surface between the rock mass and marble,the fold axial and interlaminar detachment surface and the inner fissure surface of the rock mass,and also confirmed the ore-forming sign.Based on the above research,the Trinity prospecting prediction model of Tonglvshan Cu-Fe deposit is constructed and the prospecting prediction is carried out.Both of the strike and tendency extension of ⅩⅣ orebody and the north of the deposit have great prospecting potential,and accurate orebody location prediction depends on large sounding geophysical exploration methods and 3D geological modeling techniques.
