Research in sedimentary geology at the University of Georgia emphasizes the sedimentology, diagenesis, and stratigraphy of modern and ancient carbonate systems. Bruce Railsback’s research seeks to recover records of paleoenvironmental change from carbonate materials ranging from Paleozoic limestones in the mid-continent U.S. to Holocene stalagmites from the U.S., Belize, Botswana, and China. Steven Holland’s research in sedimentary geology centers on the sequence architecture of shallow marine deposits, primarily carbonate strata of the lower Paleozoic. Recent field areas of faculty and students have included the southern Appalachians, the mid-continent, and the Cordillera.
