Location: Room 322 Geology Geography Building, 210 Field Street, Athens, GA 30602 The X-ray powder diffraction (XRD) lab primarily supports geological, archeological, and geomicrobiological research and is for student training at the University of Georgia (UGA). The current XRD system is a Bruker D8-Advance. Research programs serviced by the XRD facility include: 1) Studies on the geologic record of climate change, 2) economic geology, 3) archeology, 4) geomicrobiology, 5) paleo- and modern ecology, and 6) continental dynamics. The facility also provides ancillary service to UGA researchers in chemistry, physics, food science, and pharmacy, as well as service to smaller regional geosciences departments with limited analytical resources. The system resides in a 37 m2 (400 ft2) room that also houses computers to support data analysis. Computers in the lab are equipped with a wide range of crystallographic software for pattern simulations (NEWMOD, CrystalDiffract, and Wildfire), cell refinements (Rietveld refinement), crystal structure presentation (CrystalMaker), and the ICDD PDF-2 data base.
