The Stratigraphy, Petrology, And Depositional Environments Of The Maryville Limestone (Middle Cambrian) In The Vicinity Of Powell And Oak Ridge, Tennessee, Michael Glenn Kozar

Masters Theses

The Maryville Limestone (Middle Cambrian) is part of the nearly 600 meter thick Conasauga Group, which crops out along a series of northeasterly trending strike belts in the Valley and Ridge Province of the southern Appalachians. The interlayered limestone, shale, and dolostone comprising the Conasauga result from the interfingering of the Conasauga Shale to the west and northwest and the Honaker Dolomite to the east and southeast. Apart from detailed lithologic and paleoenvironmental work concerning Conasauga strata in southwestern Virginia and northeasternmost Tennessee, few studies have examined the Maryville in detail in east Tennessee.

In the study area, a total …

Late-Quaternary Vegetational And Geomorphic History Of The Allegheny Plateau At Big Run Bog, Tucker County, West Virginia, Peter A. Larabee

Masters Theses

Paleoecological analysis of a 2.3 m sediment core from Big Run Bog, Tucker County, West Virginia (39° 07'N, 79° 35'W), provides an integrated and continuous record of vegetation change for the Allegheny Plateau of the central Appalachians for the past 17,000 yr from the full-glacial conditions of the Wisconsin through Holocene. Big Run Bog (980 m elevation) is high-elevation wetland within the Allegheny Mountain section of the Appalachian Plateaus physiographic province.

From 17,040 yr B.P. to 13,860 yr B.P. the plant communities surrounding the site were a mosaic of alpine tundra dominated by sedges (Cyperaceae) and grasses (Gramineae) with total …

Characteristics Of Thrust Fault Imbrication Along The Western Margin Of The Blue Ridge Structural Province Buffalo Mountain, Tennessee, Mark Morgan Duddy

Masters Theses

The Buffalo Mountain thrust sheet, located along the western margin of the Blue Ridge structural province in northeastern Tennessee, provides an excellent opportunity to examine transitional structural styles and deformational mechanisms between the Valley and Ridge and Blue Ridge.

The Buffalo Mountain sheet is composed of a sequence of Lower Cambrian Chilhowee Group elastics that have been thrust over Upper Cambrian Conasauga Group shales and Cambre- Ordovician Knox Group carbonates. The entire stack has been imbricated into four interleaved thrust slices and is folded into a northeast trending doubly plunging syncline.

Field mapping and indirect examination of thrust plane orientations …
