Sedimentary Petrology & Geochemistry

Current Research Interests

Paleoclimatological and paleoenvironmental records contained in carbonate materials, and especially in stalagmites.  This research uses the petrography, mineralogy, carbon isotope geochemistry, oxygen isotope geochemistry, U-Th isotope ratios, and minor element chemistry of stalagmites, other speleothems, and other carbonate materials as proxy records of climate change, and other environmental change, in the past.

Research Interests:

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 (C and O stable isotope analysis and trace-element geochemistry) to understand stalagmites as records of past climate.

Much of this work has been done in collaboration with Dr. George A. Brook of the UGA Geography Department, and it has focused on stalagmites from southern Africa, the southwestern United States, China, India, and Belize.  This work has been supported by NOAA and NSF and was the subject of M.S. thesis work by Margaret Rafter and Hillary Sletten.  Ph.D. student Ny Riavo Gilbertinie Voarintsoa has now joined this effort too.

More recent collaboration has been with Juan Ramon Vidal-Romani and his colleagues at the University of La Coruna in northwestern Spain and with Fuyuan Liang of Western Illinois University.  That work has focused on stalagmites from northwestern Spain, and it has been funded by the Spanish Ministry of Science and Technology.  UGA undergraduate Rachel Sellers has completed a senior thesis on one of the Spanish stalagmites.

In addition to those ongoing efforts. M.S. student James Baldini's thesis focused on relationships between drip rates and speleothem morphologies, and Joe Elkins's Ph.D. work investigated ways to extract more meaningful carbon isotopic compositions from speleothems. Italian doctoral student Gulglielmo Angelo Caddeo's visit in 2009-2010 also continues to bear fruit in terms of process-oriented, rather than paleoclimatological, research on the geochemistry of speleothems.


Railsback has been supported as a PI and Co-PI by the National Oceanographic and Atmospheric Administration (NOAA) and National Science Foundation (NSF), and indirectly by the Spanish Ministry of Science and Technology.
