中文摘要：

木吉村铜钼多金属矿田位于太行山成矿带北段、阜平幔枝与上黄旗—乌龙沟断裂的叠合处,成矿潜力较大,但构造复杂,研究程度低。通过构造特征和钻孔岩相分析,对木吉村铜钼矿田进行了系统研究,综合分析认为：（1）区域上同期闪长玢岩体分布受NE向褶皱和NNE向断裂的控制,均发育于2处断裂的交会处;（2）木吉村矿田中F4断层为铲式正断层,其错断区域拆离断层并沟通深部岩浆,形成了区内的木吉村岩体,是矿田内主要的控岩、控矿构造;（3）岩浆及岩体与围岩接触带是矿液的主要运移通道,形成了木吉村、浮图峪等铜矿,F4断层是另一个运移通道,小立沟、铁岭矿区成矿主要受其控制;（4）岩体蚀变由内向外依次分为强硅化带、钾化带、石英绢云母化带、强绢云母化带和青磐岩化带,岩体外围是矽卡岩化带,受断层控制整体向NNW倾斜,反映成矿热液沿断层由深向浅,由SE向NW方向运移矿化。

英文摘要：

Mujicun Cu-Mo polymetallic ore field is located in the north Taihang Mountains metallogenic belt,Fuping mantle branch structure and Shanghuangqi-Wulonggou fracture of the composite.Metallogenic potential is tremendous,but the structure is complex,low degree of research.In this study,structure analysis and petrographic analysis of drilling in Mujicun ore field was conducted.Comprehensive analysis and conclude：（1）The same period of porphyry diorite distribution in the region is controlled by NE folds and NNE faults,which developed on its join;（2）In Mujicun ore field,F4 fault is a shovel-type normal fault,which dislocated the regional detachment faults,and communicate deep magma,formed the Mujicun rock mass,which is the main structure of rock-ore controlling;（3）The contact between rock mass and surounding rock is the main migration pathway of ore-bearing fluid,and F4 fault that controlled Xiaoligou,Tieling ore deposite is another migration way;（4）Alteration from inside to outside is divided into strong silicified zone,potassic alteration zone,quartz-sericite alteration zone,strong sericitization and propylitization zone,peripheral is skarn zone,tending to NNW which controlled by faults.
