摘要
鹅公山火山盆地受郯庐断裂系影响，ＮＷ断裂构造尤为特色：张扭性，倾向ＮＥ，右行下滑，对盆地中３个铀矿床及绝大多数铀矿（化）点具明显控制作用，是铀矿成矿的关键要素。研究ＮＷ断裂对在鹅公山火山盆地及其它地区找矿都具有实际意义。
Influenced by the Tancheng-Lujiang fault system,the NW-trending fault structures in Egongshan basin are characterized by tensile-shearing, NE-dipping and dextrorotaty downslipping,having an obvious control over three uranium deposits and the overwhelming majority of uranium occurrencs,and are the key factors to uranium mineralization. The study on the NW-trending fault structures is of practical significance in ore prospecting in Egongshan basin and other areas.
