Sedimentology and Surface Processes

The sedimentology program is strongly rock oriented with current research focusing on the Eocene Green River Formation of Colorado and Wyoming and carbonate rocks in the northeastern states. We study modern sedimentary systems to better understand physical, chemical and biological processes at the Earth's surface. Current research focuses on the chemistry of ancient seawater; long-term survival of extreme microorganisms in fluid inclusions; and brine evolution, evaporate deposition and microbial ecosystems in high-salinity closed basin sedimentary systems and other "extreme" environments. Research on surficial processes include computer modeling studies of ocean-atmosphere interactions and computer models of earthquake wave – unconsolidated sediment interactions, and factors affecting preservation of organic matter in sedimentary basins.
