Detailed explanation-1: -Geochemistry is the discipline of the earth sciences that studies the processes that control the abundance, composition, and distribution of chemical elements, compounds and isotopes in natural environments.
Detailed explanation-2: -Geochemistry is the branch of Earth Science that applies chemical principles to deepen an understanding of the Earth system and systems of other planets. Geochemists consider Earth composed of discrete spheres-rocks, fluids, gases and biology-that exchange matter and energy over a range of time scales.
Detailed explanation-3: -Geochemistry plays an essential role in our understanding of processes that produce economic concentrations of minerals whether by hydrothermal, magmatic, metamorphic, hydraulic (both surficial and subterranean) or weathering agents, or a combination of these. Geochemistry also contributes importantly to exploration.
