In recent years, geochemical survey has seen a high-speed development not only at the technical level but also at the ideological level. The disturbances of organic material and eolian sands on anomalies over some special landscape areas have been solved. Deep-penetrating geochemical survey techniques such as electrogeochemical survey techniques, aerosol geochemical survey techniques, active metallic element geochemical survey techniques in search for concealed ore deposits have gradually matured in theory and application. Exploration technique of tectono-geochemistry has been one of key technology in the locating, predicting and evaluating of buried ore deposits, and has formed a complete technical process. Artificial neural network and other new methods for analysis of geochemical data have been steadily improved. The system of muti-purpose regional geochemical survey has been established, which helps concurrent development of resource survey and environmental survey. In the future, geochemical survey will get more and more applications in such fields as agriculture, land use and plan, environmental early warning and protection.
