摘　　要：大柳行地区断裂构造多呈北东—北北东向展布,构造倾角SE40°-90°之间,局部有反倾现象,矿脉产状基本与成矿构造产状一致。脉岩多为闪长岩与煌斑岩,与矿脉呈共伴生及穿切关系,且脉岩的存在对构造成矿具有一定指示意义,脉岩蚀变与矿化强度一定程度上呈正比关系,矿脉在两者穿切位置及断层两侧常形成局部富集带。The fault structures in the area of the great willow area are mostly North East and north to North East,with the dip angle of SE40 degree-90 degrees,and the part has the reverse inclination,and the occurrence of the vein is basically the same as the formation of the metallogenic structure.The diorite and the porphyry are mostly diorite and porphyry,which are associated with the veins,and the existence of the veins is of certain indicating significance to the ore formation.The alteration of the vein rock is proportional to the mineralized strength,and the vein often forms the local rich zone on both sides of the cut and the two sides of the fault.
