Late Paleocene-Eocene Syn-Orogenic Fluvial Sedimentation and Detrital Fission Track Thermochronology of Laramide Syn-Orogenic Sediments, Denver Basin, CO (thesis)
This study investigates the Laramide foreland syn-orogenic sediments preserved in the Denver Basin, CO and interprets the Late Cretaceous-Eocene tectonic and climate history of Central Colorado. This thesis is divided into ... -
Late Wisconsin Glacier Surface Elevations and Flow Directions from the Beartooth Plateau to the Clarks Fork Valley, Wyoming
During the Pinedale glaciation of the Late Wisconsin, an ice cap covered most of the land comprising the Beartooth Plateau and the highlands to the south, stretching to the Clarks Fork Valley in northwestern Wyoming. The ... -
Martian North Polar Crater Morphology: Implications for an Aquifer
Recent studies of martian north polar craters have suggested that they have more cavity fill than the global crater population, and that the morphology of the crater fill is in some cases-similar to pingo structures on ... -
Microfacies of the Middle Ordovician New Market limestone in Rockbridge County, Virginia
Two� sections were measured and their microfacies defined macroscopically at two locations in Rockbridge County, Virginia. Nineteen microfacies are defined on the basis of detailed petrographic study of one section. Most ... -
Microstructural and Lattice-Preferred Orientation Analyses of Ductile Shear Zones: Maggia Nappe, Switzerland
Microstructures of 24 samples and quartz lattice-preferred orientations (LPO) of 13 samples from the crystalline Maggia Nappe, Switzerland were measured in order to assess the deformation history, mechanisms, and conditions ... -
New Constraints on the Timing, Rate, and Style of Exhumation of the Wood Hills and Pequop Mountains, Elko County, Nevada (thesis)
In this study, zircon (U-Th)/He analysis is used to documents the timing, rate, and style of exhumation of the Wood Hills and Pequop Mountains, which are part of the Ruby Mountains-East Humboldt Range metamorphic core ... -
The Removal of the Jordan's Point Dam: Examining Channel Restructure and Sediment Mobilization (thesis)
The 2019 removal of the Jordan's Point Dam, a low-head concrete structure built in 1911 but predated by several older crib dams, is understood to have served as a significant geomorphological event in the Maury River. ... -
Sensing Fluid Pressure During Plucking Events in a Natural Bedrock Channel: Cowpasture River, VA (thesis)
Bedrock river erosion by plucking -- the wholesale removal of bedrock blocks -- is likely the dominant non-glacial driver of incision into topography over both short- and long-term timescales. Engineering and physical/numerical ... -
Sequence Stratigraphic and Structural Interpretation, Modeling and Restoration in the National Petroleum Reserve in Alaska (NPRA) (thesis)
This thesis examines Mesozoic progradational clinoform sequences, as well as deformation associated with the Brooks Range orogeny in the National Petroleum Reserve in Alaska (NPRA). Brookian, Beaufortian and upper Ellesmerian ... -
Serpulids as Indicators of Mid-late Holocene Climate: Timing and Paleoclimate Significance of Large Worm Tube Aggregates, Lago Enriquillo, Dominican Republic
Large aggregates of calcareous serpulid worm tubes recorded paleoclimate conditions as they colonized the mid to late Holocene Enriquillo embayment, Dominican Republic. Serpulid worms flourished in the embayment following ... -
Tectonic Evolution of the Chugach-Prince William Terrane: U/Pb Detrital Zircon Age and Provenance of Cover Strata to the Paleocene Resurrection Peninsula Ophiolite in Seward, Alaska (thesis)
The southern margin of Alaska is defined by a late Mesozoic to Cenozoic accretionary complex that comprises the Upper Cretaceous to Eocene Chugach-Prince William (CPW) terrane. The Contact Fault serves as the current ... -
Terrestrial Mercury Cycling in Northern Michigan: Honeysuckle Creek Watershed and Burt Lake (thesis)
Mercury (Hg), a potent environmental toxicant, affects the cognition and health of both human and aquatic ecosystem populations. Despite regulation-driven decreases in atmospheric mercury levels, Burt Lake is among the ... -
The Sedimentology of the Snowden Member of the Late Precambrian-Early Cambrian (?) Harper's Formation in Central Virginia
The Snowden Member is the thickest and most mappable of the quartzose sandstone units of the heterogeneous Harpers Formation, the middle unit of the late Precambrian-early Cambrian(?) Chilhowee Group in central Virginia. ... -
The Stratigraphic Relationship of the Catoctin, Unicoi and Harpers Formations Within a Fault-bounded Rift Basin in Central Virginia
Sediments deposited within a rift basin that is now situated in the Blue Ridge region of central Virginia include spilitic metabasalt, which exhibit pillow structures, alluvial slump deposits, fluvial channel sands, deltaic ... -
δ13C and δ18O Analyses of Carbonate Concretions and Nodules and the Evidence for a Cretaceous Greenhouse (thesis)
The Aptian-Albian Torok Formation and Nanushuk Formation rocks of Slope Mountain, also known as the Marmot Syncline, have been interpreted to represent shallow marine, deltaic, and fluvial depositional environments. ...
