Studies Of The Law About Vertical Migration Of Geochemistry Elements In Sandy Grass Landscape Region Of Inner Mongolia

Regional geochemical exploration in our country adopt sampling media stream sediment survey as the main,supplemented by measuring soil investigation method,the traditional geochemical survey work less consider the effect of element distribution regularity of the elevation difference,the uniform particle size range samples,a single exception for delineating anomaly threshold,leads to some high background values of marking out the false anomaly,and even some small and medium-sized to mineralization anomalies of metallogenic information is hidden,the particularity of the regional geochemical landscape conditions,increased the difficulty of geochemical interpretation evaluation.For example: in some known abnormal effect is not obvious in mining area,a small scale,single element combination,even abnormal deposits of main ore-forming elements effect is not obvious or without exception shows;Some abnormal elements,however,large scale and good combination,but no deposit was found in the field.Resulting in huge waste of manpower,material and financial resources.Based on Inner Mongolia chifeng city ZhaGanMuLun 1:50000 picture of geology and mineral resources survey project as the backing,in view of the east Mongolia under the arid and semi-arid sand grassland landscape in northern area of the occurrence form of geochemical elements in vertical and the migration enrichment regularity is studied."Elevation correction coefficient method proposed in this paper through the control function of average elevation segmentation of elements content summary elements supergene vertical migration rule,to solve the problem of different media content level and eliminate interference factors,such as aeolian sand blocking high background is unusual,highlight the weak anomalies and has played a very good effect."Elevation correction coefficient method is used to" deal with geochemical exploration data,delineating the anomaly prospecting target areas is more obvious,strong mental focus more in line with the mineralized points are located,is beneficial to saving the cost of exploration,improve the prospecting precision.
