Geochemistry is the scientific study of the Earth’s chemical composition and processes, integrating principles from chemistry, geology, and physics to understand the mechanisms behind the distribution and interaction of chemical elements within the Earth’s crust, mantle, atmosphere, and oceans. This field explores topics ranging from the formation of minerals and rocks to the behavior of elements at high pressures and temperatures within the Earth. Geochemistry also plays a crucial role in studying the cycling of elements and their isotopes through Earth’s systems, which helps in understanding past climates, biogeochemical cycles, and the formation of natural resources. Moreover, it provides insights into environmental issues such as pollution and resource management. Applied geochemistry is used in the exploration of mineral and hydrocarbon resources, and in assessing environmental contamination and remediation strategies. The field has expanded to include the study of other planets, contributing to planetary science and the search for life beyond Earth.
