Structural And Stratigraphic Relationships Of Ortho- And Paragneisses Southwest Of Marion, North Carolina, Brendan Richardson Bream
Structural And Stratigraphic Relationships Of Ortho- And Paragneisses Southwest Of Marion, North Carolina, Brendan Richardson Bream
Masters Theses
This thesis examines the stratigraphic and structural relationships in the western Inner Piedmont of several orthogneisses and a paragneiss sequence. Detailed mapping was completed for an area slightly larger than one 7.5-minute quadrangle and is located southwest of Marion, North Carolina, at the northeast outcrop termination of the main Henderson Gneiss unit. From bottom to top, the stratigraphy of the study area consists of the Tallulah Falls Formation, Poor Mountain Amphibolite, and Poor Mountain Quartzite. Amphibolites and amphibole gneisses of the Tallulah Falls Formation, Poor Mountain Formation, and Dysartsville gneiss are interpreted as tholeiitic basalts related to rifting along the …

Depositional And Diagenetic Relationships Of The Honaker-Nolichucky Formational Boundary (Middle Cambrian, Conasauga Group), Southern Appalachians, Gary Alan Ottinger
Masters Theses
The upper Honaker and lower Nolichucky Formations (Middle Cambrian, Conasauga Group) in northeastern Tennessee comprise part of a thick pericratonic Cambro-Ordovician passive margin sequence along the eastern edge of North America. Throughout the Cambrian, the interplay of autocyclic controls, including sediment supply, tectonism and accompanying subsidence, and eustasy, resulted in various sedimentary architectures, including the Conasauga platform and intrashelf basin adjacent to the craton. To date, the Middle Cambrian westerly carbonate sections adjacent to and within the intrashelf basin (near Knoxville) have been studied in considerable detail. Particularly, these studies have proposed a third-order sequence boundary near Knoxville as well …
