摘　　要：塘坝金矿赋存于泥盆系下统桥头组的地层中,含矿层为石英绢云母千枚岩、砂质板岩等多种岩性层。成矿受背斜轴向断裂构造和复式背斜鞍部裂隙构造控。金矿化受背斜轴向断裂构造和鞍部层间剥离裂隙构造控制的中低温热液交代型金矿床。Tangba gold deposit occurs in the strata of the lower devonian qiaotou formation,and the ore-bearing strata are quartz sericite qianmian and sandy SLATE.Mineralization is controlled by the axial fault structure of anticline and the saddle fracture structure of composite anticline.Gold mineralization is a middle and low temperature hydrothermal metasomatic type gold deposit controlled structure.
