According to data available,the present Paper dealt prelimboily with the problemof concentration clarke values used traditionally by some regions geochemists for estimatingenrichment and impoverishment of different elements in different geological units.On such a basis,a new method for calculating regions concentration coefficients has been advanced in whichaverage regional background values of elements are used instead of their clarke values in thecrust,and the regional spatial distribution patterns of trace elements have been Studied,with fairly good results obtained.
