Application Of Geoelectric Extraction Method On Prospecting Research In Copper-nickel Mining Area Of Zhouan,Henan Province

There are important strategic resources in the basin and the surrounding areas in China,which is the most important area for the new round of mineral resources exploration.However,it is difficult to carry out mineral exploration in the basin and the surrounding area because of the problem of caprock.The deposit located in the margin of the basin,which is a completely hidden large copper nickel deposit discovered in the Qinling Mountains-Dabie orogenic belt.It is difficult to find concealed copper and nickel deposits in this area,because the ore bodies are covered by the Archean metamorphic rocks and Cenozoic alluvial deposits.The method of Geoelectric extraction is based on the dynamic equilibrium state of ions in underground minerals,We can get the change rule of the content through the analysis of the samples,so as to achieve the purpose of detecting concealed deposits.By previous collected the research data of others and field measurements.The author detailed analysis and summary of the regional metallogenic background,geological characteristics and geological characteristics of the deposit,the application and effect of the geoelectric extraction method of the studying area.And got the following Seven conclusions and understanding:1.The geological characteristics of the rock body and ore body of the studying area show that the rock body has the characteristics of deep melting,and the copper nickel deposit is formed by the late deep liquation,the re enrichment of the self metamorphism,and the late stage hydrothermal superimposition.2.The electrochemical dissolution experiments show that under the applied electric field,the copper nickel ore samples in the electrolytic cell produced a strong electrochemical dissolution.It is further clarified that the action of the applied electric field can dissolve the mineral part.3.The feasibility study of the section shows that it is feasible and effective to find concealed copper nickel ore in study area.4.In accordance with the anomalies associated elements in the symbiotic and combination Combined with the abnormal size,strength,and the surface geological environment of Cu,Ni,Co,Cr,to comprehensive explanation and evaluation of these anomalies and sorted.And got the metallogenic prospect of Cu anomalies: Cu-4,Cu-3,Cu-5,Cu-1,Cu-2;the metallogenic prospect of Ni anomalies:Ni-4,Ni-3,Ni-5,Ni-1,Ni-2;the metallogenic prospect of Co anomalies: Co-4,Co-5,Co-6,Co-1,Co-2,Co-3;the metallogenic prospect of Cr anomalies: Cr-4,Cr-6,Cr-1,Cr-7,Cr-3,Cr-2,Cr-5.5.It is the first time to fuse the elements data of geoelectric extraction.According to the fusion model to deal with the elements data of geoelectric extraction.Through the comprehensive comparison of Cu,Ni,Co,Cr elements before and after the fusion of abnormal information and geological information,we can see that the anomaly intensity and continuity of each anomaly zone after fusion are enhanced,and the reproducibility is good.6.Comprehensive geological spatial distribution characteristic,geoelectric extraction of single element anomalies,superposition of multiple element data fusion results and information,in the region is divided into ?,?,?,? abnormal area,provide the basis for depth prospecting of the studying area.7.Through the analysis of week um copper nickel deposit metallogenic geological conditions,summed up the metallogenic model,comprehensive research results geoelectro extraction test and experiment section area,summarizes the geological prospecting signs,geoelectro extraction for prospecting and exploration,the establishment of regular partial extraction of copper and nickel to find concealed ideal mode.
