Abstract:

Geochemical exploration data is an important basis when carried on regional geological survey and prospecting.During process the regional geochemical exploration data，a series of problems occurred：how to splice the multi-sheet geochemical data in different landscape area，background value and geological unit；how to screening abnormality in different contexts；how to select area by general characteristics of the ore-forming elements；and so on.Based on partition standardization，the study uses geochemical exploration composite anomaly method and consider main related characteristic of ore-forming elements.Then，using post-standardized comprehensive abnormal to screen abnormal and to select regional constituencies，it is significant for regional prospecting.

Key words: Geochemical exploration data processing, Partition standardization, Comprehensive abnormal
