Southern Alaska crustal exposures provide an excellent opportunity to study the growth of collisional continental margins through the processes of terrane accretion, magmatism, accretionary prism development, and subduction of oceanic...
The Great Smokey Group and the Mineral Bluff Group of the southern Appalachians Blue Ridge contain units of metaconglomerate that contain stretched quartz pebbles. Quartz pebbles have been widely used as strain markers in conglomerates....
Two major thrust systems are located along the eastern Blue Ridge â western Blue Ridge boundary in the Alabama and Georgia Appalachians. The pre-metamorphic Hillabee thrust is near the trailing edge of the Talladega belt thrust sheet...
Stable isotopes of oxygen, carbon and nitrogen were used to understand the ecological changes induced by human activities. The existing method developed by McLaughlin et al. (2004) for determination of the oxygen isotopic composition of...
This dissertation research has used stable and radioactive isotope techniques to address several important issues in paleoclimate and paleoecoloical research which includes the reliability of using stable carbon isotope composition of...
The Cartersville area in Georgia lies at the junction between the Alabama Recess and the Tennessee Salient. The rocks here are the easternmost exposures in the foreland fold and thrust belt of the southern Appalachians. It is bounded to...
Carbon isotopes were used as tracers in the Florida Everglades to investigate the sources and sinks of dissolved organic carbon in natural and constructed wetlands and provide a way to monitor ecosystem restoration efforts. Stable carbon...
Dissolved organic matter (DOM) is well known for its strong binding capacity for trace metals. In order to better predict the role of DOM in the speciation and transport of trace metals in the environment capillary electrophoresis (CE), ...
Altitude Effect on the Stable Isotope Chemistry of Tooth Enamel from Modern Herbivores in Tibet: Implications for Paleoclimate and Paleoelevation Reconstructions
A total of 123 bulk and serial enamel samples were obtained from modern goats, horses and yaks from southern Tibet for C and O isotope analysis. The δ13C and δ18O values of tooth enamel were compared with the δ13C values of local...
The Paleozoic growth of the eastern margin of the North American continent is exemplified by the amalgamation of a series of terranes due to the closure of intervening ocean(s) and the obduction of fragments of oceanic and continental...
Employing stable carbon and oxygen isotope analyses (including d13C and d18O of structural carbonate in mammalian tooth enamel and d18Op of fish bone samples) to reconstruct paleoecology and paleoenvironments, this dissertation strives...
