In the exploring geochemical region of the large scale, the geochemical varieties are regionalized, and geochemical field is showed as compounded.Avariety of geochemical functions may be reflected by different elemental associations, multiplicate variograms and multifractals. And so, the methods of R-mode factor analysis, single-variate factor Kriging and multifractals are used in the present paper, to disperse the compounding geochemical field.
