Members of the Geochemistry research group at the University of Georgia share an interest in using the distinctive crystallochemical and geochemical behaviors of major and trace elements, and their stable and radiogenic isotopes, as probes into a wide variety of terrestrial and extraterrestrial processes. Active research programs include biogeochemistry, economic geology, high-temperature geochemistry, isotope geochemistry, and planetary geochemistry. Research work in this area is also carried out at UGA’s Savannah River Ecology Laboratory, which houses additional analytical capabilities, including a high throughput stable isotope mass spectrometer and a laser ablation ICP-MS. Faculty and students in geochemistry have been funded by federal agencies and private organizations, including the National Science Foundation (Geosciences, Biosciences and International programs), NASA, the Department of Energy, the National Oceanic and Atmospheric Administration, exploration and mining companies and the clay industry (J.M. Huber, Corp. and IMERYS). Students have received support from the Geological Society of America, Sigma Xi, the Clay Minerals Society, the Society of Professional Well-log Analysts, the Howard Hughes Program, and the Department of Geology through the Miriam Watts-Wheeler and Allard funds.

Main Areas of Interest

The application of conventional and laser microprobe stable isotope techniques for economic geology studies is my main area of research interest. I have also recently become involved in some very interesting geobiological and paloeclimatic studies in the past several years thanks to a number of collaborative studies…

Current Research Interests

In the past, my research focused on the petrology of the continental crust. Work by my research group showed that few granitoid rocks in nature are pure anatectic melts - peraluminous leucogranites are the only ones that fit this description. Most other granitoid rocks represent hybrid magmas, that contain variable…

Petrography and Geochemistry of Stalagmites as a source of information about past climate change has been the main area of my recent research.  My work has combined the petrography of stalagmites (the distribution of spelean carbonate minerals, non-carbonate detrital minerals, crystal fabrics, layering, and critical surfaces) with geochemistry…

Clays and clay minerals are nature's most common nano-material. The study of both natural and synthetic nano-composites made up of clays and organics offers great promise for the discovery of new materials for use in medical, pharmaceutical, and material industries. Knowledge of clays is essential for the exploration and exploitation of…

Radiocarbon dating; isotope and trace-element geochemistry; archaeological science; environmental studies (heavy metals/industrial pollution and global and prehistoric climate change); terminal Pleistocene archaeology; prehistory of the Northern Plains, American Southwest, Alaska, and Northeast Asia; contact and acculturation, scientific method…
