The Application Of Integrated Geophysical And Geochemical Methods In Mineral Prospecting In Jirigen Forest Area

With the rapid and stable development of our country's economy,our country's economic strength has jumped to a new level.Technological innovation and technology diffusion have also entered an active period.The development of the economy and society has gradually increased the demand for mineral resources,which has led to the improvement of the comprehensive ability of mineral exploration in China.The development of the economy and society has gradually increased the demand for mineral resources.which has led to the improvement of the comprehensive ability of mineral exploration in China.At the same time,it also puts forward higher requirements for mineral exploration technology.Therefore,the comprehensive method of geophysical and geochemical exploration is becoming more and more widely used at the present stage.Gravity and magnetic exploration in geophysical prospecting methods are directly or indirectly looking for all kinds of mineral resources by means of physical difference and abnormal characteristics of target geological body and surrounding rock.The method is mature and widely applied.Geochemical exploration is based on geochemical principles to study the distribution of elements in the surface and underground parts of a region,and find out the geochemical rules,and further guide the prospecting methods.Geochemical exploration can narrow the target area for prospecting and accurately delineate the range of mineralization.The application of synthetic geophysical and geochemical exploration method can reduce the loss of manpower,material and financial resources,realize the geological target more effectively,and realize the precision prospecting.The geophysical and geochemical exploration comprehensive processing method is applied to Xingan Meng Jirigen forest area of actual data processing research,the main contents are as follows.1.Analysis the analytical continuation,interpolation and cutting method,nonlinear filtering and equipotential field separation method,derivative method,Euler deconvolution and other boundary recognition methods.Research the principle and applicability of the method.Processing and interpretation of magnetic data of the measured weight,The late Paleozoic sedimentary structure is identified,and the burial depth of sedimentary basins is understood,and the buried structural fracture zones and fault zones are delineated.According to the physical characteristics of the fault zones,the kinematic properties of the structural belts are analyzed,providing the basis for the establishment of the tectonic framework.2.The physical properties measurement of rock samples in the study area,and then summarizes the statistical analysis of petrophysical characteristics,combined with the region the focus of geochemical anomaly areas of mineral exploration,by detecting the magnetic density,geological prospecting,reach the purpose,mainly used in the search for iron and copper,lead and zinc deposit.Speculate on the deep ductile form of the mass and structure in the comprehensive section,provide basis for basic geological survey and mineral investigation.3.Based on the above analysis process,the structural zoning and fracture location of the study area are determined,and the prospecting target area is delineated.Meanwhile,the advantages and disadvantages of the geophysical and geochemical exploration method are summarized,and suggestions and prospects are given.It provides reference for the follow-up of this area and related geophysical and geophysical work.
