Mineral geochemical prospecting includes three stages: regional exploration, reconnaissance and detailed geochemical survey, and every stage has its unique work features. However, geochemists in China are used to conducting reconnaissance and detailed survey according to the concept of regional chemical survey, which results in inadequate implementation of some work and insufficient obtaining of geochemical information. Based on organizing and analyzing different purposes and characteristics at each geochemical stage, field investigation, indoor information processing, anomaly classification and verification, and laboratory analysis, the authors have reached the conclusion that the progressive geochemical survey from regional exploration through reconnaissance to detailed geochemical survey is equivalent to the change of sampling media from stream sediments through soil to rocks, and during this process sampling density gradually increases and the connection of the work with the geological body becomes closer and closer. This is a systematical process approaching to the prospecting target.
