The January 15 deadline is only a few days away for "The Ouachita Orogenic Belt: Structure, Foreland Basins, Tectonics, and Geophysics," a session at the Geological Society of America South-Central Meeting in Austin, Texas, on 4-5 April 2013. Information and instructions for abstract submission may be found at the following link: http://www.geosociety.org/sections/sc/2013mtg/techprog.htm DESCRIPTION: The Ouachita and Marathon orogens appear to be one continuous fold-thrust belt. Synorogenic sediments derived from the evolving fold-thrust belt were deposited in associated foreland basins and, in some cases, incorporated into the thrust belt as the orogen evolved. The hinterland was strongly deformed and metamorphosed while rocks in the frontal belt were less metamorphosed and undeformed in the foreland basins. The foreland basins and associated stratigraphy in the fold-thrust belt contain a large amount of unconventional gas-shale and oil shale reservoirs. Therefore, a better understanding of the structural/tectonic evolution is very important to determine their economic significance. This session will explore the geometry and kinematics of these transitions, including the stratigraphy, provenance, characteristics, and the economic potential of rocks within the foreland basins and the fold-thrust belt. This session will be a showcase for researchers who study fold-thrust belts and associated foreland basins of the Ouachita-Marathon Orogeny and provide a formal discussion for understanding many important questions related to the sedimentology, stratigraphy, structural geology, and tectonics of the orogen. CONVENERS: Ibrahim Cemen (University of Alabama, Dept. Geological Sciences); Gregory Dumond (University of Arkansas, Dept. of Geosciences); Randy Keller, University of Oklahoma, ConocoPhillips School of Geology and Geophysics). We hope to see you in Austin!
