摘　　要：桃山地区燕山期花岗岩为铀成矿有利岩体,断裂控矿作用明显,NE向桃山断裂、罗坑断裂的次级裂隙和破碎岩带为主要的含矿构造。燕山晚期的中酸性脉岩与铀成矿关系密切。本文在含矿构造、航空放射性异常、地面伽玛异常、航磁异常等预测要素分析的基础上,圈定了铀成矿靶区,指出桃山地区铀资源量扩大的前景及方向。笔者认为,桃山铀矿田部分地段的矿化深度具有沿控矿断裂自南西向北东方向逐渐变大的趋势。In Taoshan orefield, the uranium-rich granite was Yanshanian pluton and uranium deposits were controlled by the sub-fracture and cataclastic rocks produced by NE trending Taoshan and Luokeng fracture belt. Late Yanshanian acid dykes were closely related to uranium mineralization. Analysis on the superposition of key ore-forming factors, including ore-controlling structure, airborne and ground radio- active anomaly and aeromagnetic anomaly etc, indicated the regional exploring orientation and 9 prospecting areas. It was believed that the buried depth of some uranium mineralization increases gradually from SW to NE along the controlling faults in Taoshan orefield.
