Geochemical analysis is a field of study that focuses on the chemical composition and distribution of elements and compounds in rocks, minerals, soil, water, and other geological materials. This type of analysis is used to study the processes that form and alter Earth's crust, as well as to understand the history and evolution of geological materials and environments. Geochemical analysis involves a range of techniques, including spectroscopic analysis, mass spectrometry, chromatography, and X-ray diffraction, among others. These techniques can provide valuable information about the composition, structure, and physical properties of geological materials, and are used in a variety of research areas, including mineral exploration, environmental monitoring, and natural resource management. Geochemical analysis is also used to study the effects of human activities on the environment, such as pollution and climate change.
