520 3 a| The Proterozoic rocks of the Blue Ridge Province consist of gneisses, metasedimentary, metaplutonic, and metavolcanic rocks. The Late Proterozoic Ocoee Supergroup is a metamorphosed (greenschist facies), poorly sorted, clastic unit that overlies the crystalline-rock basement complex. The Wading Branch Formation and Longarm Quartzite are two formations of the Ocoee that outcrop along a five mile roadcut on Interstate 40 in Pisgah National Forest, Haywood County, North Carolina. Three west-verging, overturned, southwest-plunging folds with nearly planar limbs, and several faults, including the Greenbrier Thrust and Cold Springs Fault, are exposed along the roadcut. Most of the folding is Taconic age, and most of the thrust movement is Alleghanian age. Forty-five oriented samples were thin-sectioned to determine percentages of matrix, quartz, and feldspars, and the lengths of the long, intermediate, and short axes of the pebbles. Near the thrust, chlorite and white mica phyllites and mylonites are present. Although the sandstones show sedimentological textural variation, most have in common plastically deformed quartz pebbles and matrix with elongated brittlely fractured feldspars. The length ratios Rf] (long to short axes) and Rf2 (intermediate to short axes) steadily increase toward the Greenbrier Thrust. "In a fold hinge, Rf range from 1.2- 2.6, 1.2 km from the thrust "In the upright limb, Rf range from 1.8- 2.9, 0.9 km from the thrust "In the overturned limb, Rf range from 2.3 - 3.4, 0.6 km from the thrust;

520 3 a| Pebble elongation is generally parallel to the fold axes, while the flattening plane is generally parallel to the fold axial plane. The deformation mechanics consisted of simple shear due to ductility contrast or flexural flow. The clockwise rotational component is due to flexural flow. Pure shear during ductile flattening, as well as simple shear roughly along the fold axes were caused by thrust fault movement. Pebble elongation parallel to the fold axes is due to rotation toward the shear plane. Shear sense on the two faults is right lateral and shear deformation extends through the footwall rocks for several kilometers away from the fault zone.;

The Late Proterozoic Ocoee Supergroup is a metamorphosed (greenschist facies), poorly sorted, clastic unit that overlies the crystalline-rock basement complex. The Wading Branch Formation and Longarm Quartzite are two formations of the Ocoee that outcrop along a five mile roadcut on Interstate 40 in Pisgah National Forest, Haywood County, North Carolina. Three west-verging, overturned, southwest-plunging folds with nearly planar limbs, and several faults, including the Greenbrier Thrust and Cold Springs Fault, are exposed along the roadcut. Most of the folding is Taconic age, and most of the thrust movement is Alleghanian age.
