| 説明 | Structurally folded & faulted sedimentary rocks in the Cambrian of Tennessee, USA.The deformed rocks shown here are part of the Rome Formation (Middle Cambrian). Folds and faults are common in mountain belts formed by tectonic collision - this outcrop is in the Appalachian Mountains, which formed by collision between Africa and North America during the Pennsylvanian. This ancient mountain-building event is called the Allegheny Orogeny. The supercontinent Pangaea formed at this time.The prominent curvilinear feature from lower right to upper left is a minor thrust fault - note the truncation of beds. A major thrust fault (= Copper Creek Thrust Fault) occurs to the left of this spot.Locality: roadcut along the eastern side of Rt. 25E, immediately south of the Copper Creek Thrust Fault (= same outcrop), just south of the Clinch River, north of Clinch Mountain, far-northern Grainger County, northeastern Tennessee, USA (36° 22' 54.64" North latitude, 83° 26' 48.86" West longitude) |
