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.
