Study On The Extraction Method Of Ranzheyong Regional Stream Sediment Geochemical Characteristics And Mineralization Information

calculator technical development aroused the development that geochemistrycharacteristic and information abstract, many method and technique emerge with the tide ofthe times, in order to turn two processings of exploring the achievement data to provide agood technique to prop up, therefore with the mineral reconnoitre for the purposegeochemistry information withdraw and unusually analyze, to how keep and outstanding thepart having something to do with mineral is unusually the key to data processing and analysissuccess or failure.Accompany with ushering in of mathematics theory and method andcalculator technique, adopt diverse Mathematical Statistics to carry on turning to explore thedata processing and various methods to carry on an auto to become diagram, raised excrescentexplanation and evaluation level.This paper is based on the original material of Qinghai province xining area1:50000stream sediment survey，Introduced method from outdoor to indoor:geochemical information-filter–extraction. Combined with geological, mathematical statistics method to the analysisof geochemical characteristics, Do11element geochemical map：Au、As、Ag、Cu、Mo、Pb、Sb、Sn、W、Zn、Bi.Then, Combined with geological characteristics and metallogenicconditions in mining area to carry on the comparative study. Using cluster analysis, factoranalysis, discriminant affinity-disaffinity relationship of them, Element combinationinformation extraction, and reveals some geological and mineralization information.The determination of threshold: Use the traditional way and new method to the11element, Realized under different abnormal limit determination method of research. Theresults showed：Eliminate different logarithmic normal distribution method and fractalmethod can effectively identify areas abnormalities, reflect mineralization.The mineralization information extraction: use Geological, geochemical and geophysicalexploration, remote sensing, and minerals…. Compound professional Building informationmodel. Using the superposition of metallogenic geological unit necessary condition ofcomprehensive information delineated five prediction areas.The region has great potential for prospecting TongQianXin silverineralization in thisregion and there are great potential for prospecting Cu、Pb、Zn、Ag in this region.
