Geochemistry is the science that uses the tools and principles of chemistry to explain the mechanisms behind major geological systems such as the Earth's crust and its oceans.^[1]: 1 The realm of geochemistry extends beyond the Earth, encompassing the entire Solar System,^[2] and has made important contributions to the understanding of a number of processes including mantle convection, the formation of planets and the origins of granite and basalt.^[1]: 1 It is an integrated field of chemistry and geology.
