Geol 610 Environmental Geosciences Winter Current Research Projects
Isotope Hydrology of the San Bernardino Region, California
The use of oxygen and hydrogen isotopes as conservative tracers to estimate basic hydrologic parameters and zones of recharge. Includes precipitation, snow pack, river, well, and spring sampling. This project is partially funded by the Environmental Protection Agency.Isotope Hydrology of Abandoned Coal Mine Lands, Indiana
Using stable isotopes as conservative tracers, we are determining sources and routing of acid mine drainage at the Green Valley and Friar Tuck abandoned coal mine sites. We have also identified and confirmed the World's second occurrence of the mineral Xeiteshanite at the Green Valley site. This project is funded by a grant from the Indiana Department of Natural Resources, and is preformed in conjunction with Deborah Dale of the Indiana DNR, and Dr. Jim Mills of DePauw University.Oxidation and Mobilization of Copper and Lead, Arizona and Australia
An examination of the conditions, products, and geochemistry of fluids produced by the weathering of natural deposits of copper and lead. We are presently studying the role of nitrogen fixation by termite mounds in producing the rare copper nitrate minerals of the Great Australia deposit at Cloncurry, QLD, Australia. We are also examining the paleotemperatures of supergene enrichment at the Morenci Mine, Arizona, and the role of extremophiles in the fixation of carbon at lead deposits in western Tasmania. This project is funded by the Petroleum Research Fund of the American Chemical Society, and is performed in collaboration with Dr. Peter Williams at the University of Western Sydney, and Dr. Timothy Rose at Lawrence Livermore National Laboratory.Geochemistry of Placer Gold Deposits, Arizona and Australia
Examination of trace element geochemistry of placer gold nuggets may be used to "fingerprint" gold from distinct source lode deposits. We are examining the placer gold from the Meekathara area of Western Australia, and the Rich Hill-Vulture District of Arizona. This work is performed in collaboration with Dr. Dante Lauretta of the Lunar and Planetary Laboratory at University of Arizona. Educational Background
