Cessation Of Grand Cycle Deposition In The Framework Of Passive Margin Evolution: Controlling Mechanisms And Effects On Carbonate Deposition And Diagenesis, Cambrian Maynardville Formation, Southern Appalachians, Bosiljka Glumac
Doctoral Dissertations
The Middle and Upper Cambrian deposits of the southern Appalachians reveal the existence of a broad carbonate platform that was facing the Iapetus Ocean to the east and was separated from the exposed craton to the west by the Conasauga intrashelf basin. This study focuses on the Maynardville Formation, which was deposited during the early Late Cambrian along the western carbonate platform margin. As the uppermost carbonate unit of the alternating shale and carbonate units or Grand Cycles of the Conasauga Group (Middle to Upper Cambrian), the Maynardville marks a change in style of passive-margin deposition reflected in the cessation …
Stratigraphy And Structure Of Part Of The Western Blue Ridge Foothills Near Tellico Plains, Southeastern Tennessee, Steven L. Martin
Stratigraphy And Structure Of Part Of The Western Blue Ridge Foothills Near Tellico Plains, Southeastern Tennessee, Steven L. Martin
Masters Theses
The Upper Proterozoic Walden Creek and Great Smoky Groups (Ocoee Supergroup) are a thick sequence of metasedimentary rocks that underlies the western Blue Ridge Foothills in southeastern Tennessee. These rocks represent synrift sedimentation along the Late Proterozoic to Early Cambrian Laurentian margin. They were subsequently deformed and metamorphosed during the Taconic orogeny (Ordovician), then brittlely deformed by northwestward thrusting during the Alleghanian orogeny (Permian). Rejected alternative interpretations suggest that the Walden Creek Group may be Middle Ordovician to Mississippian in age, and deposited in a post-Taconic successor basin, possibly during the Acadian orogeny. Those interpretations require that these rocks were …
The Greenbrier And Hayesville Faults In Central-Western North Carolina, Camilo Montes
The Greenbrier And Hayesville Faults In Central-Western North Carolina, Camilo Montes
Masters Theses
Detailed mapping in the easternmost western Blue Ridge of central-western North Carolina revealed that the premetamorphic Greenbrier fault separates the Snowbird Group from Great Smoky Group, and the Haysville fault separates eastern Blue Ridge assemblages from the Ocoee Supergroup units and western Blue Ridge basement. The faulted nature of the Snowbird-Great Smoky Groups contact suggests that the Great Smoky Group may have been transported northwestward farther than previously thought along the Greenbrier fault, and permitted the reinterpretation of changes in Snowbird Group stratigraphy within the footwall of Greenbrier fault previously associated with lateral facies changes later telescoped by Paleozoic thrusts. …
