Analysis of Geochemical Anomalies of the Xidi Copper Deposit, Xinjiang

The Xidi Copper deposit is located in the sub-geochemical area of the eastern zone of Bogeda orogenic belt.Controlled by the secondary branched fault,this area is has a complicated geological structure and a well developed magmatic rock.The strata that lie in the area are mainly composed of bimodal volcanic rocks of the Liushugou Formation with the strike of strata being controlled by regional structure,mainly in the NEE direction.In addition,we can see a large amount of dolerite intrusion and an intensive hydrothermal activity of the late magmatic stage.The mainly geochemical anomalies are the combination of Cu,Pb,Zn,Au,Sb,As,Hg,Ti,of which the Cu,Pb,Zn,Ni,Cd,and As are obviously enriched.So they are the main ore-forming elements and indicator elements.The aeromagnetic anomaly is generally flat and slightly negative anomalies(△T=-120 to+120nT),and the gravity anomaly(amplitude-140 to-170×10^-5m/s²) extrudes southward from the central bulge,which corresponds to the northward narrowing of the.corresponds aeromagnetic anomaly.Diabase is closely related the formation of copper deposit in Xidi.The IP profile shows that there are two high-profile polarization anomaly areas,showing a very prominent high polarization and a low electrical resistivity,indicating that the lower part is quite possible to have a concealed copper ore body.
