Detailed mapping of the Greenville 1[degree] x 2[degree] quadrangle has outlined the Paris Mountain thrust sheet, dominated by sillimanite-mica schist, biotite gneiss, and amphibolite. It overlies footwall biotite gneiss and sillimanite-mica schist of the Six Mile thrust sheet. Structural analysis of regional foliation patterns (i.e., warpings of the dominant metamorphic schistosity) indicates pervasive, broad, upright-inclined macroscopic folding of the Inner Piedmont rocks with half wavelengths of 9--15 km. These folds plunge northeast and east at shallow-moderate angles (4[degree]--44[degree]), post-dating emplacement of the Paris Mountain allochthon. At exposures near Enoree Church, folds of this generation have developed after an episode of tight, overturned folding of schistosity. The age of the macroscopic folding episode (Taconic , Alleghanian ) is unknown.

New sensitive high-resolution ion microprobe (SHRIMP) titanite geochronology suggests that the contrasting shear systems developed synchronously. We argue that the macro scopic structural and metamorphic architecture satisfies the diagnostic criteria outlined by recently proposed channel flow models, and thus the remarkably well-preserved Petermann orogen is potentially an example of ancient intracontinental channel flow.
