Research

Our research group is studying the geochemical behavior of sulfur and metals in two settings: sediment-hosted ore deposits and soils and waters contaminated with heavy metals. (Please click on the highlighted links for more information on some of our past and current work.) For sedimentary ores, we have worked on deposits of iron, manganese, gold, uranium, and copper. Current projects include S and Sr isotopic chemistry of the Red Dog deposit in Alaska and similar deposits in Cuba, C-S geochemistry of black shales hosting Cu mineralization in Zambia, and diagenetic evolution of Au-bearing Witwatersrand quartzites in South Africa.

We also have an extensive program of research on soils and paleosols. Current projects are an investigation of S isotope chemistry of constructed wetlands receiving acid mine drainage and a study of the distribution of heavy metals in urban roadway soils.

Finally, our groundwater research group is pursuing problems of groundwater/surface water interactions and methodologies for developing well-head protection plans.
