ESCI 33500. GEOCHEMISTRY Geochemistry explores the chemical interactions between and among Earths spheres, including the chemistry of the physical environment and anthropogenic impacts. Topics include crystal chemistry, magmatic evolution, isotope systems and their applications, and chemistry of the hydrosphere. Geochemical methods include x-rays, electron beam, and mass spectroscopy. Global geochemical data management is also considered. Three hours of lecture and three hours of lab weekly. [MNS]
