Chemical geodynamics, developed as an integrated study of the chemical and physical structure and evolution of the solid Earth, is a field of inquiry that originally evolved from a marriage of mantle geochemistry and geophysics. Conceptually it treats the different spheres and parts of the Earth as a whole system rather than isolated ones. Advance in the theory of plate tectonics has made it the forefront of modern geochemistry. It deals with the chemical composition of different spheres within the Earth and interactions between them, so that various geological processes within the Earth can be recognized substantially. This paper briefly introduces the importance of chemical geodynamics in solid Earth sciences, generalizes the features and outstanding achievements of chemical geodynamics since its birth, and highlights the scientific significance of chemical geodynamics studies. It is proposed that China has its own advantage to conduct high-level research in the chemical geodynamics of crust-mantle interaction and the Qinling-Dabie-Sulu or ogenic belt is a very important target for this purpose.
