geochemii
Geochemii, or geochemistry, is the study of the chemical composition of the Earth and the processes that shape it. It examines how elements are distributed among rocks, minerals, waters, soils, and the atmosphere, and how these distributions change through time and space. The field seeks to explain rock formation, weathering, element transport, and the origin of natural waters and minerals, using chemical and isotopic evidence to trace processes from microenvironments to planetary scales. The modern discipline owes much to Victor Goldschmidt, whose classification of elements into lithophile, siderophile, chalcophile, and atmophile groups helped organize geochemical thinking, and to the isotope work of scientists such as Clair Patterson, which advanced dating and source-tracing methods.
Geochemical methods combine field sampling with laboratory analyses. Techniques such as ICP-MS and TIMS measure trace

Geochemii is a dynamic, interdisciplinary field that integrates chemistry, geology, physics, and biology to interpret Earth
