INTRODUCTION AND HISTORY: THE FORMATION OF THE APPALACHIAN MOUNTAINS
The Appalachians are a chain of mountains that run from eastern Newfoundland, Canada to Alabama, US. They are the result of three major orogenic events that divide, by means of major thrust faults, into separate provenances: the Valley and Ridge province, the Blue Ridge province, and the Piedmont, from West to East respectively. Each provenance formed at a different time and is comprised of regionally distinct lithologies (Chernicoff, 1995).
The Valley and Ridge province consist of Paleozoic marine sediments that were folded and thrust to the northwest by compressional forces …show more content…
Doom: N 41.032100°; W 77.448117°
Strike and Dip Measurement: 064; 019° SSE
This site is located approximately 5 km SE from the axis of the Nittany Valley Anticline, and 9 km SW of Site 5. This site is an outcrop of a greyish-red, fine-grained, heavily crossbedded sandstone from the Juniata Formation. The formation outcrops along the northwest facing flank of an incised valley along a dirt access road. Measurable units are not readily available at ground level. Measurements were taken along a 45 m accent. On the ascent a visual observation of the bedding planes revealed that at higher elevation the dip began to trend in a more shallow direction.
Figure 6. Rose diagram of clean data; Mt. Doom site. Dip azimuth was constrained, using the preliminary rose diagram, to a range of 139-172° to eliminate erroneous data points.
Site 7-Doc’s Stop: N 41.093533°; W 77.480233°
Strike and Dip Measurement: 240; 082° N
This site is located approximately 6 km N from the axis of the Nittany Valley Anticline, and 7 km NW of Site 6. The formation is a heavily jointed and steeply tilted sandstone from the Juniata Formation. Close up observations and measurements were not able to be taken due to the road-cut being in a precarious location. Measurements were taken on a preliminary trip to the location and were used for
