The Chunky Gal Mountain complex is a mélange consisting of largely metasedimentary matrix and abundant fragments and blocks of different rock types, including metasandstones, plagiogranites, amphibolites, and ultramafites. The mélange, as described here, is situated in the Blue Ridge geologic province of North Carolina. It may be part of a much larger mélange terrane, here called the Eastern Blue Ridge mélange, which extends southwestward into Georgia and Alabama, and northeastward to Virginia. The mélange at Chunky Gal Mountain has been generated during successive episodes of thrusting and shearing. It is probably of Acadian and/or Taconian age and represents the effect of either island arc-continent or continent-continent collision.
