Qingchengzi ore field is located at middle of Liaoning-Jilin rift,northern of China-Korean platform Yingkou-Kuandian uplift,experienced multiphase tectonic movement.Since the 20 century,Qingchengzi ore field have been found more than ten gold deposits,such as Baiyun,Gaojiabaozi,it is one of the most well-known domestic gold field.But the genesis of Qingchengzi gold deposit is also the focus of many scholars’debate.In order to define the relation between the nappe structure and the ore-controlling,the genesis of gold deposit was duscussed with the angle of nappe structure deformation.According to the occurrence of gold deposit and the relationship with nappe structure deformation and with magmatic hydrothermal alteration,the ductile shearing deformation-hydrothermal reformation metallogenic model was build,and the gold deposit mineralization types are divided into two categories:(1)developed in the shear zone,controlled by shear deformation and hydrothermal alteration superimposed combination types of deposits;(2)developed in the secondary faults interchange or formation contact zone,controlled by faults and hydrothermal deposit.
