| Jidongwan mining area in Luocheng County,Guangxi Province is located 1?4km north of Shebao Village,Naweng Township,Luocheng County,Guangxi Province.It is located at the junction of Huanjiang River and Luocheng,and at the intersection of the outer contact zone of the western margin of Pingying granite body and the eastern margin of Tianpeng granite body.It is located in the southeast edge of Guizhou Plateau,Yunnan Province,with an altitude of100?1200 meters.The region has a typical subtropical monsoon climate.In order to solve the problem of deep prospecting in Jiedongwan ore area,Luocheng county,Guangxi,the geoelectrochemical integrated technology was used to search for hidden tin copper polymetallic deposits in the ore area.The main results obtained through this series of research work are as follows:1.In order to study the application effect of geoelectrochemical exploration techniques and methods,including the characteristic content of each element.In this paper,the 0-line section of Jidong Bay tin copper polymetallic mining area controlled by engineering is selected to carry out the feasibility study of the method.The geoelectrochemical integrated technology was used to test the feasibility of searching for ore bodies.The experimental results show that obvious anomalies can be detected in known ore bodies.The corresponding degree with ore body is high,which can better reflect the buried position of tin-copper body.It shows that the geoelectric integration technology is feasible and has good effectiveness and adaptability in searching for tin-copper polymetallic deposits in this area.2.Multi-element statistical analysis and plane feature analysis of combined element anomalies are carried out on the geoelectric data extracted in the study area.The results show that the elements extracted from Jidongwan mining area can be divided into four combinations.F1: Cu-Ni-Co-Pb-Zn;F2: Ag-Bi;F3: W-Sn;F4: B.By using the geoelectric extraction method to extract elements,we can see the situation of the abnormal plane of element combination: each element anomaly is simple and clear,with large abnormal intensity and good continuity;The anomaly had good encapsulation and obvious zoning.The geoelectrochemical assemblage anomaly is mainly distributed in the vicinity of the contact zone between the Wentong Formation of Sibao Formation and the early intermediate and acidic rock mass of Sibao Group,which is obviously controlled by the NNE-SN trending fault zone,and is misplaced by the influence of the late NW trending fault.The geoelectrochemical anomalies in the study area are large in scale and relatively concentrated,with high definition and obvious zoning of abnormal concentrations,which has great prospecting potential.3.Based on the comprehensive analysis of geo-electrochemical integration technology and element anomaly characteristics in Jidong Bay mining area,according to the strength,size,matching degree and morphological characteristics of anomaly scale,combined with geological location and geological characteristics,two A-class target areas are obtained in the study area,namely A-1 and A-2;Class B has two target regions,B-1 and B-2,respectively.The study area is considered to have favorable geological conditions for mineralization,which provides an important basis for the optimization of deep Sn-Cu polymetallic ore prospecting target area. |
