Geochemical exploration is dominated by regional geochemical exploration and multi-objective regional geochemical survey, carried out integrated operation of high-density large data, large information, and obtained remarkable achievements in the aspects of resources and environment during '12^th Five-Year Plan'(2011-2015).These achievements have produced extensive influence and important economic and social benefit, and hence exploration geochemistry has become the most active field in geological work. The general framework and scientific system of modern exploration geochemistry have been gradually established with the investigation as the basis, the theory as the guidance and the integration of resources and environment into one body. In the ecological field, the investigation system, theoretical system, evaluation system, pre-warning system, restoration system and method system have been established with the nationwide multi-purpose regional geochemical survey as the basis and the ecological geochemical theory as the guidance. All these achievements mark the maturity of the discipline. This paper describes in brief the composition, connotation and interconnection of the exploration geochemistry framework and system. In addition, some new thinking and new concepts related to this field are put forward for discussion.
