Summary:
Macon Complex, the Macon melange of earlier usage (Higgins and others, 1988), is tectonic, sedimentary, and metamorphic chaos, properly referred to as melange. Rocks have previously been assigned to the Charlotte, Kiokee, Kings Mountain, and Lowndesville belts and to parts of the Uchee, Raleigh, Pine Mountain, and Inner Piedmont belts. Is divided into 3 melanges that reflect different structural regimes in the accretionary wedge: Juliette melange, containing the Potato Creek and Gladesville tectonostratigraphic lithofacies; Po Biddy melange; and Falls Lake melange. Overlies the Georgiabama thrust stack; structurally underlies the Little River Complex (new name) of the Little River thrust stack, of which it forms the lower unit. Intruded by Devonian plutons. Age is Late Proterozoic (author's late Precambrian) to Middle Cambrian.
