Research on the Structural Superimposed Halo and Blind Ore Forecast of Kuangou Gold Deposit in Tianshui County,Gansu Province

Kuangou gold deposit located in the southwestern margin of the North Qinling fold belt,the deposit is strictly controlled by the structural,Yuzigou secondary fault is the main ore-controlling structure of this area.The intrusive rocks are well developed in the region,quartz syenite veins are closely related to gold mineralization.Based on the metallogenic theory of the epithermal gold deposit,we use new technology of structural superimposed halos to carry out deep blind ore prospecting work in this area,and establish the model of structure superimposed halo.Through analysis of the structure superimposed halo of the mine,we find that the mineralization have the characteristics of multi-stages superimposed.
