Shimiaozi Gold deposit in Xiuyuan county,Liaoning Province occurs in porphyric biotite monzonitic granite body and is controlled by a traceable “S”fracture.It is characteristic of magmatic hydrothermal gold deposit.The “S”fracture is in NE direction consisting of several fractures.Overprinting localities of the fractures are the conductive fracture of ore fluid and bends of the “S”fracture favorable for the ore fluid accumulation where higher grade ore generally occur.%岫岩石庙子金矿床产于似斑状黑云二长花岗岩体中,受“S”形展布的追踪断裂构造带控制；具有典型岩浆热液金矿床成因特点.在NE向“S”形展布的断裂构造中,构造复合部位对成矿有利；构造的转弯处储矿条件较好,金的品位相对较高.
