| 摘 要： | INTRODUCTIONGeochemists need to study the spatial distribution of theassociations of the geochemical elements(AGE) to delineatethe geochemical blocks or recognize geochemical anomalies inregional geochemical exploration.Regional geochemical divi-sion (RGD) is a mapping technique for the division of thestudy area into slices where the natural AGEs are relativelysimple and uniform.A practical approach to RGD is to digital-ly devide the collected geochemical samples into groups bymeans o…
