gequímica

Geoquímica is a scientific discipline that studies the chemical composition of the Earth and other celestial bodies, as well as the processes that control the distribution and abundance of chemical elements. It combines principles from geology and chemistry to understand how elements move and interact within the Earth's systems.

The field investigates the origin and evolution of the Earth's crust, mantle, and core, as well as the processes involved in rock formation, weathering, and the cycling of elements through the atmosphere, hydrosphere, and biosphere. Geochemists use a variety of analytical techniques to determine the elemental and isotopic composition of rocks, minerals, water, and gases.

Key areas of study within geochemistry include the distribution of elements in the Earth's crust, the formation of ore deposits, the chemistry of hydrothermal systems, and the isotopic analysis of geological materials to date rocks and trace the history of geological processes. It also plays a crucial role in understanding environmental issues, such as pollution, acid rain, and the fate of radioactive waste. Furthermore, cosmochemistry, a sub-discipline, applies geochemical principles to study the composition and origin of meteorites, planets, and other extraterrestrial materials, providing insights into the formation of the solar system.
