Abstract Using background values of several groups of strongly correlated elements obtained in 1:200000 regional geochemical survey, the authors made a tentative division of geological lithologic units in the survey area. A comparison between the division result and the geological maps available shows quite good consistency. This method can play a fairly good auxiliary role in geological mapping.This paper also analyzes the cause for inconsistency in local areas and probes into the method for solving this problem.
