A Research Of Prospecting Hidden Deposit By Using Geological-geochemical-Geophsical Comprehensive Method In Gadaban Mining Zone, Tibet Province

Tibet area has always been a hot spot for geological workers and researchers in China to find a breakthrough.It is a major geochemical landscape in the plateau cold mountain area,which is undoubtedly a difficult challenge to the conventional exploration method under this special landscape condition.This paper has first applied geoelectro chemical integration technology of deep penetration ability of deep ore prospecting in Tibet mining area Bangzhuoma.This paper has carried out a comparative study of geo chemical integrated technology and soil geochemical survey method and the effectiveness test of geoelectric integration technology in the Tibet mining area,and discussed the rationality and regularity of the application of this technology in the high cold mountain area to find the deep gold polymetallic ore body.The integration technology reflects the abnormal area of deep ore body information,strengthens the extraction of abnormal information,and analyses the abnormal characteristics of soil thermoluminescence measuring method,soil ionic conductivity method and geoelectric extraction method,and determines the prospecting mark of the best geoelectric integration technology in Bozhuoma mining area.Based on the geochemistry integration technology,the geological and tectonic features of the mining area are integrated,and the ore prospecting model suitable for the geo electric integration technology in the bond area is set up,and the prospecting prediction of the deep edge of the geoelectric integration technology is carried out in the mining area and in the periphery.The following main studies have been made:1.in this paper,we choose the 0 exploration line of Bozhuoma mining area to carry out the GeoelectroChemical integration technology and deep mine effectiveness test.The results show that it is not only above the known ore body of buried depth of 200 meters,but also speculates below 400 meters of the known ore body extension.The geo chemical integration technology presents a clear relationship between the abnormity of soil thermoluminescence,the abnormal conductivity of soil and the abnormal nesting relation of the ore-forming elements extracted by electricity.It is said that the integrated technology of electrochemistry in the mine can be used in this mining area.The deep ore body is indicated effectively.At the same time,the comparative study of GeoelectroChemical integration technology and soil geochemical survey method was carried out.The experimental results show that the geoelectric integrated technology shows that the abnormality of deep ore body is better than that of soil geochemical survey.2.the extraction of anomalies of gold and polymetallic deposits in Tibet plateau cold mountain area is mainly Au,Ag,Cu,Zn and Pb.The coincidence between As element and Au is better.3.The optimum temperature range of thermoluminescent mercury in the cold mountain area of Tibet plateau is 280? ~ 330?,the valence state of mercury is dominated by vulcanization state,and the vulcanization state of mercury may be the companion of the formation of gold during the hydrothermal period.Soil heat release mercury,sulfide mercury and gold polymetallic are closely related.4.the application line metal quantity and standardized surface metal quantity are quantitatively prominent,and the geochemical prospecting technology reflects the deep prospecting area with good effect.5.Comprehensive geological and geoelectric integration technology research results,the establishment of ore prospecting model in the bang Ma mine area,for the future in the same similar geochemical landscape area for deep prospecting and prediction provides a feasible technical means.6.According to the geological characteristics and the abnormality of the soil thermoluminescence,the abnormal ionic conductivity of the soil,the abnormal contrast of the geoelectric extraction elements and the comprehensive anomaly superposition,three comprehensive abnormal target areas of ?,? and ? are divided in this area,which provides the basis for the deep prospecting in this area.
