Geochemical And Geophysical Characteristics Analysis And Prospecting Assessment Of Langliu Copper-Niekel Mining District In The Funing Yunnan

Yunnan Funing area contains abundant resources of copper and nickel,uplift is located in the southeastern Yunnan fold belt of the South China fold system.The study area is located in the south-west of Funing.Based on the previous research results,this study has carried out the work of geophysics and geochemistry chieved the following understanding:Cu?Ni?Co?V?A?Ag?Au As?Pb?Ti?Zn?Mn and so on.Based on the soil geochemical data,11 pedogeochemical anomalies were obtained.:u?Ni?Co?V?Ag?Au?As?Pb?Ti?Zn?Mn and so on.Cluster analysis was carried out on these elements and the results of R cluster analysis showed that in the case of r(correlation coefficient)greater than 0.4,it can be divided into 4 Correlation combinations:(1)Cu?Ni?Co(2)Pb?Mn?Ag(3)Au?As?Zn(4)V?Ti.There are remarkable correlation among Cu?Ni.The worst correlation is Pb.Based on the data of electrical exploration,9 IP anomalies are summed up.there is a strong correlation between high polarization and mineralization.Based on the data of high precision magnetic survey obtained 11 magnetic anomaly.The depth of the magnetic field is known by the difference field method.Based on the geological and previous research results the magnetic anomaly is explained.Interpretation and analysis of geophysical and geochemistry anomalies in combination with data.The relationship between ore body and anomaly is summarized.4 prospecting target areas were obtained in this study;respectively Y1,Y2,Y3and Y4.According to the principle of anomaly classification,the anomaly is divided into 3 levels,:Y3,?:Y2andY1,?:Y4.Metallogenic conditions of geology is very favorable in levels I or there are utcrop of ore body.There are an important area of looking for copper nickel mine area.
