摘要

Determination of lower limits of the element anomalies are the key problem in geochemical exploration. Because distribution patterns and background values of elements in different geological bodies are quite different, it is not proper to adopt an identical value in an area with complex geology. As an example of the river sediment geochemical data at scale 1∶200 000 for an area in Zhangkou of Hebei Province, the authors lineated elements anomalies for different geological bodies on basis of analyzing the element distribution law. The result is better than that of adopting an identical value.oft-com:office:office" />
