Geochemistry Exploration Technology Based On The Ore In LiuLin District, GuangXi Province

Solid mineral exploration geochemistry is based on the geochemistry indicators generated in or after the process of mineralization because of the migration and dispersal of metallic and nonmetal elements, Then measuring the surface metal and nonmetal element anomalies for looking for hidden or blind metal deposits. In addition, because the field equipment is simple and the sampling speed is fast, with the improving of methods of analyzing and testing samples and the using of computer data processing, geochemical exploration of solid mineral exploration has become an essential method of exploration techniques. In the paper, it takes geochemical exploration as the search method for concealed deposits in LiuLin in the preparatory work.LiuLin is a new mining area, located in the large faults in Southeast CenXi ~ BoBai metallogenic belt in GuangXi province with folds and faults develops, and magmatic activities is frequent, in addition, it’s between the PuBei and LuChuan granite rock base, which helps the migration and accumulation of mineral components, so it has good geological conditions and mineralization prospecting. The mineral resources are rich there especially gold, silver, tungsten, molybdenum, lead, zinc. Therefore, it’s very meaningful to study the geochemical exploration methods of looking for deep concealed ore in this area.The geochemical work distributed by soil geochemical exploration and geochemical stream sediment survey.The first method is to arrange six test lines in the direction of vertical to the fault zone. With 183 samples of 12 indicators, access to the 2160 data, it’s drawn that the anomalies of test line 16 is resulted by mineralization according to the anomalies of the main mineralization elements Au, W and other elements.Based on the results of the test lines, in order to verify the geochemical distribution of Au, W and other major metals in this area, and in order to discover useful anomalies, then delineating the prospecting targets and providing a reliable geochemical basis for carrying out mining exploration work in the next step. According to the topography and geography of this area, geochemical stream sediment survey with the scale of 1:50000 is adopted, With 197 samples of 12 indicators, access to the 2364 data, it’s derived from the geochemical analysis of the data from the results of the study area that unit 13 is the concentration of metallic mineralization zone, but unit 28 is the concentration of tungsten and molybdenum. By calculating the areal productivity, I know that it’s mainly Pb, Zn polymetallic, followed by Au mineralization near unit 13 and tungsten and molybdenum mineralization near unit 28, therefore, these two modules can be as the prospecting targets.
