摘　　要：利用1∶20万区域化探中具有强相关性的几组元素的背景值,对测区的岩性地质单元进行尝试性的划分,将划分结果与已有的地质图对比,二者扣合较好,该方法对地质填图有很好的辅助作用;另外对局部地区不能很好扣合的原因进行了分析,探讨了解决的方法。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.
