| The Ergun area in Inner Mongolia is located on the western slope of the northern section of the Da Xing'an Mountains.It is also part of the Ergun metallogenic belt.At present,many ore such as the Laogou gold deposit,the Dongjun and the Villa Valley Pb-Zn(Ag)deposit are found in the area.A deposit with good selectivity and high economic value.In order to implement the national sustainable development strategy and expand its prospecting achievements,the work that the previous people have completed is important information.The experimental research and application of conducting geo-electrochemistry integration technology in this area to find concealed ore.The integration technology is subdivided into three methods: 1.Geoelectric extraction measurement method,2.Soil mercury release measurement method,3.Soil ion conductivity measurement method.Based on the results of the experimental research and analysis of the data of the former people in the mine area and the geo-electrochemical integration technology of the ground,after careful study and summary of the abnormal distribution characteristics of the geo-electrochemical indicators of the study area and the geological background,the following understandings and achievements were obtained:(1)The Geluqiduanshan mining area is located in the northeastern part of the Ergun precious metal and non-ferrous metal metallogenic belt.The geological data of this area are summarized: the ore-bearing stratum is mainly in the lower part of the Ergun River Formation,and the lithic gray block Metamorphic sandstones of the marble and dolomite marbles.The wall rock alteration is dominated by medium-low temperature erosion such as silicification,carbonation,and sericitization.The ore body trend is65°,tending to the southeast,the dip angle is about 78-85°,and the local is nearly erect,subject to the northeast.The control to the fracture is more obvious.(2)The feasibility test for finding concealed ore is carried out on the known section of the No.15 exploration line in the Geluqiduishan mining area.The test results show that the Au?Ag?Cu?Pb?Zn?As?Bi measured by the technical method The nine elements such as Mo and Li and the elements such as RHg and Con have a high degree of coincidence with the ore body(mineralization zone),and the Cu?Pb and Zn anomalies are synchronous,which proves that the technology is feasible and effective.(3)The elemental variation coefficient and discrete characteristics indicate that theelements of Cu?Zn?Bi?Li?Pb and other elements in this area have many high-strength data,large variation range,certain enrichment trend,and great mineralization potential.(4)Convert the original data of the element into the lining value,and then use the statistical analysis methods such as R-type cluster analysis and R-factor analysis to summarize the best combination of ore-seeking elements in the mining area,so the 9elements are divided into F1: Ag-Pb-As-Li-Mo-Cu,F2: Au-Bi,F3: Zn-As three groups,and the inner and outer bands of the elements were divided by histogram method,and the abnormal plan was drawn using software such as Mapgis and CorelDRAW.(5)Under the premise of combining geological and geo-electrochemistry prospecting indicators,three prospecting targets are designated for the Distinguishable Mountain Geoelectric Research Area,one for each of the I,II and III target areas.The comprehensive geological and geoelectric indicators suggest that the Class I target has the most potential for prospecting. |
