Characterizing Petrophysical Properties of Carbonate Rocks Using Nuclear Magnetic Resonance and Complex Conductivity
(University of Kansas, 2019-12-31)Carbonate rocks are well known for their highly complex petrophysical behaviors due to their intrinsically heterogeneous pore geometry and wide range of pore sizes. As a result, both effective characterization of carbonate ... -
Stable Isotope Geochemistry and Paleohydrology of the Poison Strip Sandstone, Early Cretaceous, Eastern Utah
(University of Kansas, 2019-12-31)The Poison Strip Sandstone Member is a unique unit in the early Cretaceous Cedar Mountain Formation of eastern Utah. A previous chemostratigraphic study of the Poison Strip Sandstone at the Ruby Ranch Road (RRR) section ... -
Evaluation of Seismicity Trends in Kansas to Determine Possible Source Mechanisms Using Focal Mechanism Inversion and Spectral Analysis
(University of Kansas, 2019-12-31)High b-value, proper stress orientation and low stress drop are three factors that support the suggestion that a majority of events in central Kansas are induced as a result of changes in pore pressure. Furthermore, stress ... -
Geochemical Fingerprinting of Yellowstone Hotspot Track (YHT) Eruptions from Ash Beds in the Central United States
(University of Kansas, 2019-12-31)Volcanic ash beds have been shown to be reliable stratigraphic marker beds because they can be radiometrically dated using magmatic minerals: e.g. zircon, sanidine, etc. This can be utilized in any region containing ash ... -
Measuring actinide partitioning in zircon to improve the 230Th correction for 206Pb/238U dates
(University of Kansas, 2019-12-31)The element Th, and its isotope 230Th, an intermediate daughter isotope in the 238U decay series, is often excluded relative to U from the mineral zircon during crystallization. Zircon is geochronologically important because ... -
The codell sandstone (upper Cretaceous) of Kansas
(University of Kansas, 1962-05-31) -
Stratigraphy and paleontology of the Eagle Ford formation of north and central Texas
(University of Kansas, 1931-05-31) -
Physiography and geology of south-central Kansas
(University of Kansas, 1934-05-31) -
Exhumation and incision history of the Torngat Mountains, northern Labrador and Quebec, Canada, using apatite (U-Th)/He thermochronology
(University of Kansas, 2005-05-31)Apatite (U-Th)/He thermochronological data provide new insights into the exhumation history of the Torngat Mountains, which are located in Ungava Peninsula, northern Labrador and Quebec, Canada. Latest Jurassic to earliest ... -
The Cherokee of Southeastern Kansas
(University of Kansas, 1936-05-01)The object of this report is to record the results of a detailed survey of the Cherokee shale. The different members of the Cherokee are described so that they may be recognized and differentiated from each other. Some ... -
Timing and drivers of exhumation in the hinterland of the North American Cordillera from detrital zircon U-Pb and (U-Th)/He double-dating
(University of Kansas, 2019-12-31)The late Cretaceous to early Cenozoic hinterland of the North American Cordillera is widely recognized as an orogenic plateau. Although most studies suggest that this highland was in place by the Eocene, the timing and ... -
Advective Transport: Importance to Groundwater Remediation and Illustration of Basic Transport Concepts to Introductory Audiences
(University of Kansas, 2019-05-31)Developing effective transport models with meaningful results requires a solid understanding of transport concepts and the underlying mechanics the model, and how data can be best integrated into the model. This research ... -
Seismic attribute analysis and CO2 monitoring within the Mississippian reservoir, Wellington field, Sumner County, Kansas
(University of Kansas, 2019-05-31)The Mississippian reservoirs are prolific hydrocarbon producers in the mid-continent of the United States but are challenging to image seismically due to their high heterogeneity and thicknesses typically below seismic ... -
A Data-driven Approach for Mapping Grasslands at a Regional Scale
(University of Kansas, 2019-05-31)The goal of this research was to use a data-driven approach to develop a regional scale grassland mapping protocol with the following objectives. First, identify and characterize the spatial distribution of grassland types ... -
Carboxylated Organic Matter Influences Magnesium Uptake in Three Low-Temperature Dolomite Models
(University of Kansas, 2018-08-31)Numerous geochemical models explain the formation of dolomite at low temperature, a controversial mineral due to its abundance in geological deposits but paucity in modern environments. Several of these models are based ... -
The stratigraphy of the Quaternary alluvium in the Great Bend Prairie, Kansas
(University of Kansas, 1988-05-31)The Quaternary alluvial aquifer beneath the Great Bend Prairie in south-central Kansas serves as a major source of water for irrigation and domestic use. Low quality saline water, however, intrudes locally from Permian and ... -
Rock Fabric Controls on Pore Evolution and Porosity-Permeability Trends in Oolitic Grainstone Reservoirs and Reservoir Analogs
(University of Kansas, 2018-12-31)Although the general influence of rock fabric on porosity and permeability (Φ-k) within carbonates is well documented, if and how pore evolution and Φ-k scatter quantitatively relate to depositional fabric remains poorly ... -
Stratal and Petrophysical Complexity Expressed in Seismic Reflection Patterns within Isolated Carbonate Platforms
(University of Kansas, 2018-12-31)Seismic data are fundamental tools for evaluating and exploiting hydrocarbon resources, yet how the heterogeneous nature of carbonates complicates imaging, interpretation, and predictability of reservoir properties from ... -
Simulating complex conductivity in carbonate rocks: using digital carbonate rocks and comparison to laboratory measurements
(University of Kansas, 2018-12-18)Digital rock physics involves the modern microscopic imaging of geomaterials, digitalization of the microstructure, and numerical simulation of physical properties of rocks. This physics-based approach can give important ... -
Interoperability between the StraboSpot graph database and GIS software– A Malpais Mesa Use Case
(University of Kansas, 2018-12-31)Geographic Information Systems (GIS) have been used by field geoscientists for decades to digitally collect data with several benefits: observations can be made in the field at a map independent scale while using multiple ...
