Geochemical modeling
Geochemical modeling is the practice of using chemical thermodynamics, chemical kinetics, or both, to analyze the chemical reactions that affect geologic systems, commonly with the aid of a computer. It is used in high-temperature geochemistry to simulate reactions occurring deep in the Earth's interior, in magma, for instance, or to model low-temperature reactions in aqueous solutions near the Earth's surface, the subject of this article.
== Applications to aqueous systems ==
Geochemical modeling is used in a variety of fields, including environmental protection and remediation,〔Zhu, C. and G. Anderson, 2002, ''Environmental Applications of Geochemical Modeling''. Cambridge University Press, 300 pp.〕 the petroleum industry, and economic geology.〔Bethke, C.M., 2008, ''Geochemical and Biogeochemical Reaction Modeling''. Cambridge University Press, 547 pp.〕 Models can be constructed, for example, to understand the composition of natural waters; the mobility and breakdown of contaminants in flowing groundwater or surface water; the formation and dissolution of rocks and minerals in geologic formations in response to injection of industrial wastes, steam, or carbon dioxide; and the generation of acidic waters and leaching of metals from mine wastes.
