The Characteristics Of Soil Geochemistry And Prospecting Potentiality Of Wusuogou Area In Inner Mongolia

The research area is located in the western area of Inner Mongolia autonomous region, isalso located in the north side of North China Platform, Non-ferrous metals such as copper andsilver minerals have favorable conditions for enriching minerals.Compared with the north China continental crust clark value (YanMingCai etc.,1997),eight elements such as silver, arsenic, antimony, gold, tungsten, lead, molybdenum andbismuth in the research area have taken place in the enrichment of mineralization, the zincloss slightly, copper loss more.This paper takes three methods such as strip method, iterative method and EDA methodto determine the background value and the anomaly lower limit value in the study area, afternormal distribution test and combining with the actual geological conditions, finallydetermine the background value and the anomaly lower limit value in the study area, useMapgis software to map ten kinds of element geochemical anomalies.After analysis anomalycharacteristics of the single element statistically:Au, Ag, Sb, As, Pb, Mo, W, Zinc, Cu and Bihave three concentration zonations, among them, Au, Ag, Sb, W and Pb anomaly concentratedin the K1bn-λ、K1bn-λπ、K1bn-vb, have large scale, high strength and a number of strongmental focus.The mathematical statistical analysis of soil geochemical data in the study area showsthat: W, Sb and As have good correlation and the correlation coefficient between W and Sb is0.84. After R cluster analysis and principal component analysis,10kinds of elements can bedivided into four types of element combination, F1for Sb-W-As combination,F2forPb-Cu-Zinc-Mo combination,F3for Au-Ag combination, F4for Bi. Among them, the Au-Agcombination is the main elements mineralization combination in the study area. Itconcentrated in the K1bn,Sb-W-As combination is a combination of elements associated withthe mineralization.Through the analysis of regional geological conditions and combination of elementsanomalies, this paper delineates eight combination anomalies, and analyzes the characteristics of each composition anomalies. It finally delineates four key prospecting potential blocks.
