摘要
Cokriging is characteristiced by both multeity and kriging’s advantages of representing the spatial attributes, which regionalizes two or more spatial attributions, and can improve the estimation accuracy in the geochemical data processing. Taking Linwang area as an example, the cokriging method is used to predict the reserve of gold element in the mineral area. The basal element combination of gold, silver, arsenic and mercury is showed by correlation analysis, which Au as the main variable element while Ag, As, Hg are the second elements. Compared with the traditional multivariate statistical methods of kriging, cokriging gets less estimated errors and high estimated accuracy. It is more superior than other methods in the predication of the mineral prospecting.
