      Fault, in geology, a planar or gently curved fracture in the rocks of Earth’s crust, where compressional or tensional forces cause relative displacement of the rocks on the opposite sides of the fracture. Faults range in length from a few centimetres to many hundreds of kilometres, and displacement likewise may range from less than a centimetre to several hundred kilometres along the. Anastasia Formation (Pleistocene) at surface, covers 24 % of this area. The Atlantic Coastal Ridge is underlain by the Anastasia Formation from St. Johns County southward to Palm Beach County. Excellent exposures occur in Flagler County in Washington Oaks State Park, in Martin County at the House of Refuge on Hutchinson Island and at Blowing Rocks in Palm Beach County.

      East of the mountains, the Brevard fault zone (Fig. ) defines the southeastern edge of the Blue Ridge and northwestern margin of the Inner Piedmont. This remarkably straight fault has moved several times, each episode characterized by a different sense of displacement. Earlier episodes were right-lateral strike slip, resulting from the. and compare the geology of the Brevard fault zone, non-migmatitic Chauga belt, and migmatitic western Inner Pied-mont.

      The geologic map of Georgia (a state within the United States) is a special-purpose map made to show geological features. Rock units or geologic strata are shown by colors or symbols to indicate where they are exposed at the surface. Structural features such as faults and shear zones are also shown. Since the first national geological map, in , there have been numerous maps which included. This task within the USGS NCGMP Piedmont-Blue Ridge Project aims to fill the void in geologic map coverage along the Fall Zone in southeastern Virginia and northeastern North Carolina, and forge strong cooperative ties within the NCGMP by combining resources across all three Program components by supporting DMME and NCGS STATEMAP and UNC–W EDMAP components with targeted geologic .

Running southwest-northeast across Alabama, Georgia, and North Carolina, the Brevard Fault Zone (or the Brevard Zone of Cataclasis) is a prominent geologic feature of the Southeast United States.

Geologists continue to debate the Brevard's structure and significance, and the nature and direction of ancient movement on the fault. The Brevard fault zone was first described and named by Keith () for exposures near Brevard, North interpreted the fault zone as a syncline of younger deformed rocks resting on ancient basement.

Jonas () recognized it as a fault zone, and concluded it is a thrust. Since then, the geologic study and interpretation of the Brevard fault zone has been controversial. difficult to separate from the later wrench/strike-slip related thrust/high-angle reverse faults.

Every fault contact on the map has some kind of mylonite or cataclastic rock along it. Mylonitic rocks are, for the most part, continuous along most faults in and northwest of the Brevard fault zone.

Google ScholarAuthor: Robert J. Hooper, Robert D. Hatcher. In geology, a fault is a planar fracture or discontinuity in a volume of rock across which there has been significant displacement as a result of rock-mass movement.

Large faults within the Earth's crust result from the action of plate tectonic forces, with the largest forming the boundaries between the plates, such as subduction zones or transform faults.

Eastern Piedmont Fault Zone. The Piedmont province of Southern Appalachians is comprised of exotic and North American terranes.

Many of the bounding faults between these terranes are wide, and well developed ductile shear zones that exhibit clear evidence of Alleghanian dextral motion. Together they define the Eastern Piedmont Fault Zone (EPFZ).
