Research Interests
Currently my research efforts are focused upon
unraveling the polyphase mid-Paleozoic
deformational pulses that assembled the crystalline metamorphic terranes exposed in the southernmost Appalachians
of Alabama and Georgia. In addition to detailed mapping and structural
analysis, I am conducting a regional geothermometry and geobarometry study
from samples collected in amphibolite facies metamorphic rocks, primarily Neoproterozoic garnet-bearing schist, gneisses, and quartzites units mapped in the eastern Blue Ridge belt. Several transverse megascopic fold
structures within the research area expose significant structural relief,
and are the subject of current structural and geothermobarometric
analysis. These studies will attempt to correlate isothermal and isobaric
surfaces with deformation produced from Alleghenian
structures- indicating that the present geometry is not solely inherited
from the original Acadian dynamothermal event. Microprobe analyses are
ongoing at the microprobe facility at the SOMED facility, University of Alabama,
Tuscaloosa.
Additional ongoing research includes the application of GIS and CAD to the
solution of geoscience problems, and the application of high resolution GPS
technology to the earth sciences.
