Abstract
Miaoshang gold deposit exists in the granite zone of the middle part of west Qinling.It is a middle-low hydro-thermal type gold deposit controlled by the fracture zone of Gaoqiao-Taoping Fault.The paper analyzed geological features of ore bodies and metallogenetic zone,and summarized the ore control factors.The study show that the ore body has the trend of richer and thicker towards deeper.
