Geokemia
Geokemia is the scientific study of the chemical properties, composition, and processes that govern the Earth and its environments. It focuses on how elements are distributed among rocks, minerals, soils, waters, and the atmosphere, and how geological processes such as weathering, magmatic differentiation, metamorphism, and sedimentation alter chemical inventories over time. The field integrates principles of chemistry with geological context to explain the evolution of the planet’s chemical system.
Geokemia employs a range of methods to analyze materials and environments. Analytical techniques include mass spectrometry,
Subfields within geokemia include hydrogeochemistry, which studies chemical interactions between water and rocks; petrogeochemistry and mineral
Geokemia has historical roots in the broader development of geochemistry and modern analytical chemistry. It informs
