Abstract
Structural Interpretations of the Norton quadrangle, located in SW Virginia includes fold analyses of the E trending (090) Powell Valley Anticline and E trending (090) Middlesboro syncline. The two structures were described to have been formed during movement on the sub-horizonal Pine Mountain thrust fault (Harris and Milici, 1977) and developed during the Alleghenian Orogeny. Analyses are to decipher the region’s structures on the map and inner geology. The most important and abundant mineral resource in the area is high volatile C to high volatile A bituminous coal. Rock types also include carbonaceous shales, fossiliferous shales, quartzose sandstones, siltstones, limestones, chert, siderite, mica and feldspar rock fragments, iron and manganese oxides, goethite, dolomite, and presence of small fossils. Sedimentary structures include trough, planar, and tabular bedding, cone-in-cone structures, cross-stratified sandstones, ripple marks. The Powell Valley Anticline has an axial plane 055.9, 80.9 S, and a hinge line of 056.5, 04.2 making it horizontally upright and gentle fold (interlimb angle). The fold was likely formed during the Alleghenian Orogeny which was active between 325 and 260 million years ago.
