Geochemistry is the study of the source and fate of chemical species in natural environments, using chemical analysis of minerals, rocks, soils and waters. One of the aims is to describe and quantify the processes that control the recycling of elements and isotopes in nature. The main applications are geochemical exploration, environmental issues, and determining the age and genesis of different rock types. There are several subfields in Geochemistry. In Isotope Geochemistry, radiogenic and stable isotopes are analysed in order to perform age determinations and make inferences on the mechanisms and conditions of rock formations or other research targets. In Environmental Geochemistry, geochemists try to identify natural and anthropological chemical changes in the environment. Geochemical Exploration utilises geochemical properties of the bedrock and its Quaternary cover for discovering new ore deposits. A huge number of geochemical analyses are performed annually in mineral exploration, resource evaluation and mining and mineral processing operations.
