Geokemiaa

Geokemiaa is the scientific study of the chemical composition of the Earth and other planets, as well as the chemical processes that control the distribution of elements and their isotopes. It seeks to understand the origin, evolution, and distribution of chemical elements throughout the Earth's systems, including the atmosphere, hydrosphere, lithosphere, and biosphere. Geochemists use a variety of analytical techniques to determine the elemental and isotopic composition of rocks, minerals, water, and gases. These data are then used to reconstruct past geological conditions, understand present-day processes, and predict future changes. Key areas of research within geokemiaa include the study of element cycles, the formation and evolution of the Earth's crust and mantle, the chemistry of ore deposits, and the biogeochemical cycles of elements essential for life. The principles of geokemiaa are also applied to environmental science, resource exploration, and planetary science.
