Depositional History, Sequence Stratigraphy And Diagenesis Of The Maryville Limestone (Middle Cambrian) Southern Appalachians, Krishnan Srinivasan

Doctoral Dissertations

The Conasauga Group constitutes part of a thick pericratonic Cambro-Ordovician passive-margin sequence along the eastern North American continent. The Cambrian carbonate platform was flanked by a high-relief shelf margin towards the east, facing the open ocean, while to the west the carbonate platform sloped into an intrashelf basin. It is this western shelf margin that is the topic of the present study. Detailed lithofacies analysis of the Middle Cambrian Maryville Limestone along a shelf-to-basin depositional transect reveals that the shelf evolved from a gently basinward sloping ramp to a rimmed platform fringed with steeper slopes. Cyanobacterial buildups (Renalcis-Girvanella) …

Carbonate Platform Response To Tectonism And Eustasy: The Middle Cambrian Carbonates Of The Lower And Middle Conasauga Group, East Tennessee, Eugene Carlton Rankey

Masters Theses

The Middle Cambrian Craig Limestone Member (Rogersville Shale) and Maryville Limestone are part of the thick Cambro-Ordovician pericratonic sedimentary package exposed in the Valley and Ridge province in East Tennessee. Exposures in the Dumplin Valley fault zone provide further details concerning the origin and development of these limestone formations.

Description of five sections, analysis of 125 thin sections and 98 slabs, and regional reconnaisance in the Dumplin Valley area reveal that the Craig Limestone Member represents "premature" demise of a carbonate shelf in that it did not develop as fully as the Maryville shelf and had no rimmed edge or …

Lithostratigraphy, Structure, And Metamorphism Of A Crystalline Thrust Terrane, Western Inner Piedmont, North Carolina, Timothy L. Davis

Doctoral Dissertations

The geology of the western Inner Piedmont of North Carolina, from knowledge gained in an area called the Columbus Promontory, is characterized by a stack of crystalline thrust sheets. In this study the stratigraphic, structural, and metamorphic development of this crystalline thrust terrane was examined.

The lithostratigraphic framework of the Columbus Promontory is divisible into four distinct and mappable rock units that include the Henderson Gneiss, Sugarloaf gneiss, Poor Mountain Formation, and the Mill Spring Complex. This lithostratigraphic framework helps define three crystalline thrust sheets within the Columbus Promontory herein, called the Tumblebug Creek, Sugarloaf Mountain, and Mill Spring thrust …

Structural Development, Strain History, And Timing Of Deformation In The Eastern Great Smoky Mountains, Jeffrey B. Connelly

Doctoral Dissertations

The present investigation reveals that the Greenbrier and Dunn Creek thrust sheets preserve well-formed ramp-related folds within the Great Smoky Mountains area. The Greenbrier thrust sheet preserves a ramp anticline at klippes of the Greenbrier thrust sheet in the eastern Great Smoky Mountains that can be traced discontinuously to the western Great Smoky Mountains where this anticline has been modified by later displacement along the Rabbit Creek fault. A ramp-related fold is also preserved in the main Greenbrier thrust sheet. The main Greenbrier fault was subsequently folded by an underlying ramp anticline within the Dunn Creek thrust sheet. These earliest …
