Stratigraphy, Petrology, Diagenesis, Paleontology, And Depositional Environments Of The Harrisburg Member Of The Kaibab Formation In Northern Arizona And Southern Utah, Zachery T. Case

Electronic Theses and Dissertations

The Kaibab Formation has two members, the Fossil Mountain Member below and the Harrisburg Member above. They were deposited in shallow-marine shelf to restricted coastal settings. Stratigraphically above are the Rock Canyon Conglomerate and the Moenkopi Formation; consisting of the Timpoweap and Lower Red members; which are the only members present in the study area. The Rock Canyon Conglomerate was deposited in depressions and as a regolith. The Timpoweap and Lower Red members were deposited in shallow marine to tidal environments.

Nine stratigraphic units were identified in the Harrisburg Member. Units one, two, three, five, six, seven, and nine are …

Petrology, Provenance, And Depositional Setting Of The Lower Tallahatta Formation (Meridian Sand) In Grenada County, Mississippi, Husamaldeen Zubi

Electronic Theses and Dissertations

The Meridian Sand represents the lowermost member of the Middle Eocene Tallahatta Formation, which is found in the Gulf Coast region of the United States. Five stratigraphic sections in Grenada County were measured and described. Twenty-one sand and sandstone samples, and 2 mud samples were collected from all sections. Textural analyses were performed on all 23 samples to determine their lithologic properties. Petrographic descriptions and modal analyses were performed on thin sections made from the 21 sand and sandstone samples, and 400 grains were point counted in each sample. Geochemical analyses were carried out on all sand, sandstone, and mud …

In Situ Dating Of Multiple Events In Granulite-Facies Rocks Of The Larsemann Hills, Prydz Bay, East Antarctica Using Electron Microprobe Analysis Of Monazite, Steven K. Spreitzer

Electronic Theses and Dissertations

The metamorphic rocks exposed along the southeast coast of Prydz Bay were affected by several metamorphic and plutonic events associated with collision in the Neoproterozoic and Cambrian. Critical units exposed in the Larsemann Hills and nearby ice-free areas include (1) basement Søstrene Orthogneiss, (2) cover sequence Brattstrand Paragneiss and (3) anatectic pegmatites intrusive into the Brattstrand Paragneiss. Zircon U-Pb data from previous studies yielded a maximum depositional age of 1023 ± 19 Ma for the Brattstrand Paragneiss, but only approximate ca. 900 Ma to ca. 1000 Ma and ca. 530 Ma ages for two metamorphic events. In order to constrain …

Re-Evaluating The Tectonic Model For The Arbuckle Mountains, Oklahoma By Spatial And Geometric Analysis Of Stratigraphic And Structural Trends, Dakota James Kolb

Electronic Theses and Dissertations

Understanding the spatial distribution and geometric relations between stratigraphy and structural features can allow for a more accurate tectonic timeline to be considered for not only the Arbuckle Mountains but for the assembly of modern North America. The Arbuckle Mountains in south central Oklahoma exhibit structurally complex stratigraphy associated with regional features like the Southern Oklahoma Aulacogen, the Arbuckle Anticline and the Washita Valley fault. Camp Classen YMCA and Turner Falls city park in Davis, OK, hosts observed, but largely unmapped, small scale structural features that best represent the magnitude of deformation. The goal of this study was to determine …
