摘要
The Wuziqilong intrusion-related hypothermal Cu deposit locates in the northeast of the Zijinshan ore field. It is hosted by Zijinshan complex consisting of mainly Yanshanian biotite monzogranites. Disseminations,veinlets and stockworks are the main ore structures. Four stage veins can be distinguished from their mineralogical paragenesis and crosscutting relationships. It can be drawn out that the fluids forming the Wuziqilong deposit evolved from initially-magmatic hypothermal NaCl-CO2-H2O system to finally-meteoric epithermal NaCl-H2O system, and that during the evolution fluid boiling occurred, volatiles such as CO2 escaped and metallic sulfides precipitated, followed by input of circulating meteoric water.
