Basal thermal state of the Greenland Ice Sheet
(University of Kansas, 2018-12-31)Understanding the basal thermal state of the Greenland Ice Sheet (GrIS) has important implications for modeling its ongoing contribution to global sea level. Apart from removing paleoclimate information from basal layers, ... -
Construction and Exhumation of the Sierra Nevada Range: an investigation of geochronology, thermochronology and trace element mineral chemistry
(University of Kansas, 2018-12-31)This dissertation describes the development of the Sierra Nevada range from its construction as a magmatic arc to its current configuration as a significant tectonic block or microplate in the western North American ... -
CHARACTERIZING GROUNDWATER FLOW THROUGH MEROKARST, NORTHEAST KANSAS, USA
(University of Kansas, 2018-08-31)Karst aquifers are a significant source of groundwater supply worldwide, yet are known for unpredictable flow paths and rapid groundwater velocity. Characterizing the complex nature of karst aquifers though dye tracing is ... -
TWO NOVEL ICHNOSPECIES: LARGE-DIAMETER VERTEBRATE BURROWS IN THE UPPER JURASSIC MORRISON FORMATION, SOUTHEASTERN UTAH
(University of Kansas, 2018-08-31)Large-diameter structures in the Salt Wash Member, Upper Jurassic Morrison Formation in southeastern Utah, are interpreted as mammal burrows. All burrow types are found in pedogenically modified clayey mudstone overlain ... -
Landslide Hazard Assessment for Fayzabad District, Badakhshan Province, Afghanistan
(University of Kansas, 2018-08-31)Fayzabad District is one of those most impacted by landslide hazards in Afghanistan, accounting for 71% of all national landslide fatalities reported between 2012 and 2017. Necessary elevation data did not cover the very ... -
Hydrology, Fluid Flux, and Chemical Travel Times through the Vadose Zone at Ehmke Playa in the Central High Plains of Kansas
(University of Kansas, 2018-05-31)Groundwater levels of the High Plains aquifer (HPA) are declining in western Kansas, due mainly to large-scale irrigation pumping since the 1950s. Previous recharge rate estimates in the Central High Plains vary between 5 ... -
Preservation Potential of Permian Gypsum Beds, Nippewalla Group, USA
(University of Kansas, 2018-05-31)ABSTRACT During the Permian, what is now southern Kansas and northern Oklahoma was a drying inhospitable environment, as evidenced by the extensive red-beds and evaporites of the Nippewalla Group. Due to the fact that ... -
Ichnotaxonomy of the Eocene Green River Formation, Soldier Summit and Spanish Fork Canyon, Uinta Basin, Utah: Interpreting behaviors, lifestyles, and erecting the Cochlichnus Ichnofacies
(University of Kansas, 2018-05-31)The Eocene Green River Formation in the Uinta Basin, Utah, has a diverse ichnofauna. Nineteen ichnogenera and 26 ichnospecies were identified: Acanthichnus cursorius, Alaripeda lofgreni, c.f. Aquatilavipes isp., Aulichnites ... -
Diagenetic controls on porosity, thermal history, and hydrocarbons in the Wolfcamp A, eastern Midland Basin, Texas
(University of Kansas, 2018-05-31)A detailed study of a Wolfcamp A core from the eastern Midland Basin, west Texas, is used to understand the diagenetic history of the region and the controls on carbonate macroporosity. Transmitted-light microscopy, ... -
Biodiversity and Evolutionary Relationships of Early Mesozoic Ray-Finned Fishes (Actinopterygii)
(University of Kansas, 2017-12-31)Fishes have evolved to exploit multiple ecological niches. Extant fishes in both marine (e.g., rabbitfishes, surgeonfishes) and freshwater systems (e.g., haplochromine cichlids, characiforms) have evolved specialized, ... -
Late Triassic North American Paleodrainage Networks and Sediment Dispersal of the Chinle Formation: A Quantitative Approach Utilizing Detrital Zircons
(University of Kansas, 2018-12-31)The Upper Triassic Chinle Formation is a succession of fluvial strata deposited in a backarc setting across the present-day Colorado Plateau of the southwestern United States. This study uses detrital-zircon (DZ) U-Pb data ... -
Implications for large-scale sea level change in the Turonian Western Interior Seaway: Evidence from the Codell Sandstone, Colorado
(University of Kansas, 2014-08-31)Middle to Upper Turonian strata of the Cretaceous Western Interior Seaway record evidence of a large-scale sea level change. The Codell Sandstone Member of the Carlile Shale, exposed in the Pueblo, Colorado area, consists ... -
Development of Tools and Methods for the Characterization of the Groundwater-Surface Water Interface
(University of Kansas, 2018-05-31)This study focuses on water exchange, and associated processes, at the groundwater-surface water interface (GWSWI). The contributions of the study, as a whole, can be divided into two groups: scientific contributions and ... -
Tectonic Evolution of the Izmir-Ankara Suture Zone in Northwest Turkey using Zircon U-Pb Geochronology and Zircon Lu-Hf Isotopic Tracers
(University of Kansas, 2017-12-31)Detrital zircons from the Late Cretaceous Murdunu-Göynük forearc basin and the Paleogene Saricakaya foreland basin; part of the greater Central Sakarya Basin located along the Sakarya Zone of the Western Pontides were ... -
High-Frequency Shallow Seismic Reflection Characterization of Overburden at an Abandon Pb-Zn Mine Beneath U.S. Highway 69 in Treece, Kansas Using Seismic Imaging and Vp/Vs Ratio
(University of Kansas, 2017-12-31)Overburden at an abandoned Pb-Zn mine beneath U.S. Highway 69 in Kansas was evaluated using P- and S-wave seismic reflection methods to estimate Vp/Vs ratio. Drilling reports indicate the mine works have lateral spans of ... -
Effects of Sedimentologic and Stratigraphic Heterogeneity on Production in Carbonate Reservoirs: An Integrated Outcrop, Synthetic Geologic Modeling, and Flow Simulation Study
(University of Kansas, 2017-05-31)Most geoscientists recognize, characterize, and understand the many scales and types of heterogeneity in carbonate reservoirs; however, systematic quantitative assessment of the impact of this range of geological variations ... -
