Allogenic and Autogenic Signals in the Stratigraphic Record of the Deep-Sea Bengal Fan
(Nature Publishing Group, 2018-05-22)The Himalayan-sourced Ganges-Brahmaputra river system and the deep-sea Bengal Fan represent Earth’s largest sediment-dispersal system. Here we present detrital zircon U-Pb provenance data from Miocene to middle Pleistocene ... -
Influence of Organic Matter Source, Abundance, and Growth Habit on Depositional Textures and Associated Pore Attributes of Hypersaline Lacustrine Microbial Deposits (Holocene, Bahamas)
(University of Kansas, 2017-08-31)Discovery of lacustrine microbialite reservoirs in South Atlantic pre-salt has motivated the search for analogs for perspectives on their deposition and initial porosity. Although previous efforts mapped spatial patterns ... -
Detrital Zircon U-Pb Geochronology and Paleodrainage Reconstruction of the Blackhawk-Castlegate Succession, Wasatch Plateau and Book Cliffs, Utah
(University of Kansas, 2017-08-31)The Blackhawk Formation and Castlegate Sandstone are Campanian fluvial-deltaic and shoreline deposits within the Sevier foreland-basin fill along the Wasatch Plateau and Book Cliffs in Utah. Long-standing age constraints ... -
Multivariate spatio-temporal visualization of over-pumping the High Plains aquifer and impacts on the Arkansas River in western Kansas
(University of Kansas, 2017-08-31)Environmental assets like arable land and water have been developed extensively with consequences such as large-scale groundwater depletion caused by agricultural irrigation. Yet even in such a dramatically affected area, ... -
Investigating the response of Greenland and Antarctic glaciers to atmospheric and oceanic forcings using a 1D flowline model
(University of Kansas, 2017-08-31)Over the past two decades, the mass loss from the Antarctic and Greenland ice sheets has contributed approximately 11.2 ~3.8 mm to global mean sea level, one third of the total sea level rise since the 1990s. The majority ... -
The Jacksonian stage in southeastern Arkansas

Late Mississippian bryozoa from Missouri
(University of Kansas, 1951) -
Integrating in situ Geochronology and Metamorphic Petrology: An Example from the Gruf Complex, European Central Alps
(University of Kansas, 2017-05-31)Understanding the thermal evolution (i.e. the timing, rate, duration, and magnitude of thermal events) within mountain belts has important implications for the geodynamic evolution of both ancient and modern orogenies. ... -
The pegmatite dikes of the Bridger Mountains, Wyoming

GPR Imaging of Prehistoric Animal Bone-beds
(University of Kansas, 2017-08-31)This research investigates the detection capabilities of Ground-penetrating radar for imaging prehistoric animal bone-beds. The first step of this investigation was to determine the dielectric properties of modern animal ... -
Analyzing the Cenozoic Depositional History of Western Kansas: A New Approach Using Paleosol Zircon Geochronology
(University of Kansas, 2017-08-31)Correlation of terrestrial strata is challenging due to the lack of continuous outcrops, limited biostratigraphy, and poor preservation of useful marker beds such as tephra layers. This improved understanding of its internal ... -
HYDRODYNAMICS OF FLUVIAL STRATA WITHIN THE WILLIAMS FORK FORMATION
(University of Kansas, 2017-08-31)Fluvial sandstones within the middle part of the Late Cretaceous Williams Fork Formation were interpreted to gain insights to hydrodynamics of the ancient fluvial system. Emphasis is placed on a thick (~75 m), laterally ... -
Joint Analysis of Refractions and Reflections (JARR) Method for Quantitatively Deriving Velocity Models
(University of Kansas, 2017-08-31)Joint analysis of refractions and reflections (JARR) is introduced and is developed as a quantitative method for improving the accuracy of near-surface velocity model functions. These accurate near-surface velocity functions ... -

Monitoring induced seismicity near the Wellington oil field, South-Central Kansas
(University of Kansas, 2017-05-31)Seismicity in the United States midcontinent has increased by orders of magnitude over the past decade. Spatiotemporal correlations of seismicity to wastewater injection operations have suggested that injection-related ... -
ASSESSING THE UTILITY OF BAROMETRIC RESPONSE FUNCTIONS IN ESTIMATING HYDROGEOLOGICAL PARAMETERS OF THE HIGH PLAINS AQUIFER
(University of Kansas, 2017-05-31)Accurate estimates of hydrogeological parameters, such as hydraulic conductivity, are important for effective groundwater management strategies and contaminant transport studies in aquifers worldwide, including the High ... -
The use of ichnofossils in geological and petrophysical characterizations of aquifers and reservoirs: Examples from south-central Texas and southeast Utah
(University of Kansas, 2016-12-31)This dissertation presents three studies that show ichnological assessment is a vital part of both hydrogeology and petroleum geology. Ichnological assessments lead to a better understanding of the effects of bioturbation ... -
Ichnotaxonomy of the Cambrian Spence Shale Member of the Langston Formation, Wellsville Mountains, northern Utah, U.S.A.
(University of Kansas, 2016-12-31)The Spence Shale of northern Utah is the oldest North American middle Cambrian (~506–505 Ma) Burgess Shale-type (BST) deposit and, unlike previously thought for BST deposits, has a very diverse ichnofauna. Twenty-four ... -
Stratigraphic Changes in Ichnopedofacies of the Upper Triassic Chinle Formation, Northeast Chinle Basin, Southeastern Utah: Implications for Depositional Controls and Paleoclimate
(University of Kansas, 2016-12-31)The Upper Triassic Chinle Formation in the Stevens Canyon area, southeastern Utah, represents fluvial, palustrine, and lacustrine strata deposited in a continental back-arc basin on the western edge of Pangea. Previous ...
