This text puts forward the duplex construct- the duplex syncline controls the mineral principle, analyzing the main mechanism of the structure to control the mineral, building up Jiguanzui copper-gold mine bed Ⅰ mineral bodies controls and permits the motive of the mineralizing mode and new principle of ore prospecting.

Magma rock are closely related with mineralization rule, Magma rock category in jiguanzui copper-gold deposit is numerous and have a characteristics of many periods and times,the deposit which mineralized is very complicated.

Geological features of Nanshan rich-gold ore pillar in Xiaoxinancha copper-gold deposit;

The analysis results of the hydrogen and oxygen isotopic elements from the Zijinshan copper-gold deposit show that the infiltration of precipitate water increased in the oreforming process from early to late, and presents the characteristics of the stage's evolution of fluid-rock interaction (Stage Ⅰ and Ⅱ ).
