由于多期地质地球化学作用的相互叠加，地球化学场通常表现为复杂的叠加场。在叠加场内，元素组合的成因特征、变差函数的多级套合结构和多标度分形谱能有效地反映地质地球化学的多期性。相应地，用Ｒ型因子分析法、单变量因子克立格法和多标度分形谱便能有效地实现地球化学场的分解。
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.
