Metallogenic Geological Characteristics and Prospecting Criterias for Gerizhuotuo Gold-copper Deposit in Southern Margin of East Kunlunu Orogen

Gerizhuotuo gold-copper deposit is located at Variscan cobalt (gold、Antimony) metalogenic belt of Buka Daba Mountain-Anyemaqen Mountains and has superior ore-forming geological conditions. But restricted by the natural condition, the Gerizhuotuo gold deposit has been found very late, its geological work degree is low and the prospecting direction is not clear. Based on the comprehensive analysis of the metallogenic geological background and the geological characteristics of this deposit, it's considered that skarn type copper deposit and alterd rock type gold deposit were mainly developed in this mining area, the former is closely related to the variscan diorite while the later has close relationship with EW-trending tectonic process. Relying on the data obtained from the deposit exploration work in recent years, the metallogenic geological characteristics and mineralization have been sunnarized, the prospecting direction and potential have been discussed in this paper for benefiting the exploring work in this deposit.
