Brevard Fault

The Brevard Fault Zone is a 700-km long and several km-wide thrust fault that extends from the North Carolina-Virginia border, runs through the north metro Atlanta area, and ends near Montgomery, Alabama. It is an important Paleozoic era feature in the uplift of the Appalachian Mountains.

Discovery
Arthur Keith from the United States Geological Survey first identified an exposed segment of the Brevard Fault in 1905, believing it to be a syncline. In 1932, Anna Jonas Stose used local petrology to identify the site as a thrust fault. Stose, the first to trace the fault, is also credited with identifying that the rocks in the area must have been formed through deformation, placing the Brevard Fault in a regional perspective. ==Geology==
Geology
The Brevard Fault Zone is a part of a much larger system of faults at the base of the Appalachian thrust sheet Many studies of the fault come from Grandfather Mountain in the Linville Fall Quadrangle, which contains the exposed region that was first discovered by Arthur Keith. This region is only 1–3 km of its 700 km length. that underwent metamorphism 350–360 million years ago. The Fault Zone is characterized by ductile behavior as indicated by the widespread presence of mylonitic and phyllonitic rocks. ==See also==
