~Appalachian geology research~
Dr. Chuck Bailey
The focus of Dr. Bailey’s research is on the
geometry and tectonic history of deformed rocks as well as the physical and
chemical processes that control rock deformation. He studies ductile fault
zones (high-strain zones) and works to understand both the deformation path
experienced by mylonitic rocks as well as elucidate the tectonic history
recorded by these important crustal structures. Although the Appalachians
Mountains have been studied for over two centuries, many key aspects of their
history remain unanswered. Our studies in the Blue Ridge and Piedmont provinces
are wide-ranging and integrate structural analysis with petrology,
sedimentology, geochronology, and geologic mapping.

Dr. Clinton Barineau
Dr. Barineau’s research focuses primarily on
the geologic history of the Appalachian Mountains, especially the southern
Appalachians of Alabama, Georgia and North Carolina. Research includes: 1) understanding the role
of accretionary orogenesis during the Taconic orogeny, southern Appalachians;
2) Refining the age, geochemical character and tectonic settings of
metasedimentary and metaigneous rocks in the western Blue Ridge, eastern Blue
Ridge and Piedmont terranes of Alabama and Georgia; 3) Strain analysis on
metamorphic rocks of the Eastern and Western Blue Ridge, Alabama; 4) Analysis
of paleorelief on the Gulf-coastal plain unconformity in the vicinity of
Columbus, GA; 5) Geology of the Uchee belt, Alabama-Georgia.

Dr. Kevin Stewart
Dr. Stewarts’ research is focused on the
structure, tectonics, and geologic history of mountain belts. Most of his work
is field based, supplemented by geochronology, thermobarometry, and sedimentology/stratigraphy.
His work in the southern Appalachians is split between the metamorphic rocks of
the Blue Ridge Province and the sedimentary rocks of the Valley and Ridge and
Plateau. Research in the Blue Ridge includes structure and tectonics of the
crystalline thrust sheets as well as work on eclogite and other high-pressure
metamorphic rocks. A new project will address the problem of the anomalously
high topographic relief in the southern Appalachian highlands and the possible
linkage with linear, post-orogenic fracture zones. His work in the sedimentary
rocks is focused on Mississippian-aged liquefaction features from earthquakes
caused by the collision of Africa with North America about 330 million years
ago. A work in progress is the construction of a model for the Paleozoic
tectonic evolution of the southern Appalachians.

Dr. Merschat’s research is focused on (1) the
structure and tectonics of the Appalachian orogen; (2) the provenance of the
different crystalline terranes of the Blue Ridge and Piedmont; and (3) the
thermochronologic evolution of the orogen. He integrates geologic mapping,
structural analysis, SHRIMP U-Pb geochronology, petrology, and geochemistry
into his research and is currently involved with bedrock geologic mapping
projects in the Blue Ridge of Virginia, North Carolina and Tennessee.
