Kekexili In Qinghai Regional Geochemical Characteristics And Mineralization Is Analysed

Through the development in western qinghai kekexili1∶200000regionalgeochemical exploration and qinghai1∶200000tahetuobanri map sheet area、buluntaimap sheet area、kekxili lake map sheet area and kusai lake map sheet area of regionalgeochemical exploration, find out the area of40element geochemical characteristics ofdistribution and concentration, to provide basic geological study of resources,environmental assessment and the geochemical basis.Kekexili region of southwest surveyed area is located in qinghai province is known as the"third pole of the world","alpine no man’s land" and " the mysterious death zone "mysterious, alpine hypoxia, bad weather, traffic is extremely difficult.By2008-2010, threeyears of field work, the work area of40307square kilometers, the field in accordance with1.56points/4square kilometers of stream sediment sampling, sample point setting withrationality both uniformity,15543stream sediment samples, according to the kilometergrid4square kilometers portfolio analysis.This article take the following results:1.In this paper, the involved in kekexili6732stream sediment combination sampledata from the processing.2.The system studied the kekexili area of40kinds of elements in stream sediments(oxide) content enrichment characteristics and distribution, to draw the As、B、Hg、Cu、Li、Mn、Mo、Ni、Sb、Zn、Al2O3、CaO、K2O and Na2O element is definitely too high,especially pointed out that the area element abundance of B、Cu、Hg、Li、Mn、Ni、Zn、Al2O3、K2O、Na2O was obviously higher than that of the province, tuotuo river on theregion. Element abundance reflected the broad area of high calcium carbonate sedimentaryenvironment and certain area distribution of magmatic rocks, also reflects the mainore-forming elements in the region.3.1∶200000stream sediment in the studied area of40kinds of discrete element dataanalysis, strong color, and image points, based on metallogenic existing facts, analysis themain ore-forming elements for Sb, Au, Cu, W, Sn, Ba, Sr, etc.4.1∶200000stream sediment in the studied area40kinds of element data clusteringanalysis and factor analysis, to obtain12representative geological elements combinationof quantitative factors, the paper analyzes the relationship between the geological unitcombination factor and.5. Qinghai kekexili region for the first time sheet, between regions, between40kinds ofelements in regional geochemical map seamless splicing, reflect the regional geologicalbackground change ups and downs of the element geochemistry and metallogenicgeochemical environment;Geological and geochemical information can be extractedclearly.
