Description: Prerequi- site(s): both CHEM 001C and CHEM 01LC or both CHEM 01HC and CHEM 1HLC or equivalents; a grade of “C-” or better in one of the following courses: GEO 001, GEO 002, GEO 009 or GEO 011. Examines the chemical principles of geologic processes at and near Earth’s surface. Topics include biogeochemical cycles of elements during chemical interactions of the Earth’s crust, hydrosphere, and atmosphere; applications of thermodynamics and kinetics to the study of low-tem- perature geologic systems; and the use of isotopic techniques in tracing geologic processes.
