Biography
Dr. Steve Dworkin is currently working as a professor in the Department of Geology at Baylor University, USA. He has completed his Ph.D. from University of Texas - Austin, 1991 & M. S., from Michigan State University, 1983 & B. A., Albion College, 1981. He study the low temperature aqueous and isotope geochemistry of sedimentary rocks and waters. My main focus is on paleoclimate reconstructions of terrestrial environments using the chemistry of paleosol calcite and organic matter. Our research group is currently studying environmental conditions during the Triassic using paleosols preserved in the Chinle Formation at the Petrified Forest National Park, Arizona. We also are continuing our work on paleosols that span the K/T boundary from west Texas. By measuring the isotopic composition of dispersed organic matter in bulk paleosols, it is possible to reconstruct the carbon isotopic composition of the late Cretaceous and early Tertiary atmosphere. This is being carried out using paleosols from Big Bend National Park in west Texas. He had so many publications.
