The oxidation of sulfides as it relates to acid mine drainage or the contaminated leachate from hydraulic fracturing or “fracking”; the role of the atomic and electronic structure of sulfide and oxide surfaces in redox reactions that immobilize aqueous species such as arsenic, chromium, and uranium (and other actinides); the incorporation of noble metals into sulfides and implications for the formation of some types of ore deposits; photochemical reactions on mineral surfaces and their role in regulating the concentration of redox-sensitive elements in the photic zones of surface waters or the atmosphere; microbe-mineral interactions
