With the development of modern experimental techniques，experimental geochemistry has introduced itself into other subjects besides geochemistry，and has been one of important means to study them. In this paper，a systematic discussion on research achievement and prospect of experimental geochemistry has been made on partition coefficients of elements between mineral (liquid)and liquid (gas)，formation of mineral phase in the high temperature and pressure，genesis and evolution of the rock in the depth，reaction between rock and liquid in supercritical fluids，dynamics of geochemistry in the open system etc.
