摘　　要：坝头矿区位于南岭成矿带内,地处郴州—怀集断裂带和英德弧形断褶带交接部位、连阳岩体北东侧边缘地段,矿区内构造活动强烈,成矿地质条件良好,为大坪—根竹园铜铅锌铁多金属找矿远景区,区域上铁、钨、锡、铜、铅和锌等多金属矿床(点)分布广泛。为了分析该矿区成矿规律和资源潜力,探究下一步找矿方向,在分析总结前人工作成果基础上,根据矿区所处区域地质背景、矿区地层、构造、围岩蚀变和矿体等地质特征,结合野外地质调查成果,探究矿床地质成因,并与周边相同成因类型矿床进行横向对比,认为坝头矿区的矿床类型属于以中高温接触带矽卡岩型矿床为主、层控矽卡岩型矿床为辅的钨-钼-铅-锌多金属矿床。矿区现阶段总体勘查工作程度仍然较低,矿区进一步找矿空间较大,具有寻找中型以上钨矿床并兼顾铅、锌和钼多金属矿的找矿前景。Batou mining area is located at the junction of Chenzhou-Huaiji fault zone and Yingde arc fault fold zone in the Nanling metallogenic belt.The area is in the northeast edge of Lianyang pluton with strong tectonic activity and good metallogenic geology condition.Daping-Genzhuyuan is the prospecting prospect for copper,lead,zinc and iron polymetallic deposits.And iron,tungsten,tin,copper,lead,zinc and other polymetallic deposits(ore occurrences)are widely distributed regionally.Based on the analysis and summary of previous exploration result,regional strata,structure,wall rock alteration,ore body and other geological characteristics of the mining area,the geological geneses of the deposit,the metallogenic pattern and resource potential were analyzed by combining with the field geological survey results and horizontal comparison with the surrounding deposits.It was considered that the deposits of Batou mining area belongs to the tungsten-molybdenum-lead-zinc polymetallic skarn deposits formed in the middle high temperature contact zone and supplemented by stratabound skarn deposits.Due to the overall low level of exploration in the mining area,there is a large space for further prospecting in finding medium tungsten deposits,and consideration should be paid to lead,zinc and molybdenum polymetallic deposits.
