Timing, Kinematics, and Spatial Distribution of Miocene Extension in the Central Arabian Margin of the Red Sea Rift System
(University of Kansas, 2013-05-31)The Arabian-Nubian Shield (ANS) existed as relatively stable craton on the southern Neo- Tethyan passive margin until rifting of the continental lithosphere borne the Arabian Plate with the advent of the Red Sea-Gulf of ... -
Diagenetic controls on porosity and permeability in Miocene carbonates, La Molata, Spain
(University of Kansas, 2012-05-31)This diagenetic study of Miocene strata from La Molata, southeastern Spain, evaluates controls on meteoric diagenesis and low-temperature dolomitization. There is a well-constrained sequence-stratigraphic framework and ... -
3-D Seismic Methods for Shallow Imaging Beneath Pavement
(University of Kansas, 2013-05-31)The research presented in this dissertation focuses on survey design and acquisition of near-surface 3D seismic reflection and surface wave data on pavement. Increased efficiency for mapping simple subsurface interfaces ... -
Paleobiogeography of the North American Late Cretaceous Western Interior Seaway: the impact of abiotic vs. biotic factors on macroevolutionary patterns of marine vertebrates and invertebrates
(University of Kansas, 2013-05-31)My research investigates the relationship between ecology, evolution, and the environment in the fossil record. I hypothesize that abiotic environmental factors (e.g., climate, sea-level, ocean chemistry, and paleogeography) ... -
Constrained Parameterization of the Multichannel Analysis of Surface Waves Approach with Application at Yuma Proving Ground, Arizona
(University of Kansas, 2013-08-31)Field data from Yuma Proving Ground, Arizona was used to test the feasibility of merging common multichannel analysis of surface waves (MASW) processing routines with mode- consistent shear-wave refraction traveltime ... -
Heterogeneity and Depositional Variability of Reef Sand Aprons: Integrated Field and Modeling of the Dynamics of Holocene Aranuka Atoll, Republic of Kiribati, Equatorial Pacific
(University of Kansas, 2013-08-31)Depositional facies represent the net product of a complex set of processes that impact sediment supply and transport through geomorphic systems. Although the general facies motifs of many isolated platforms throughout the ... -
Paleotopography and Sea-level Controls on Facies Distribution and Stratal Architecture in the Westerville Limestone Member (Upper Pennsylvanian) NE Kansas and NW Missouri
(University of Kansas, 2012-05-31)Oolitic grainstone facies form important reservoirs in the subsurface around the world. The Westerville Limestone Member (Pennsylvanian) is an oolitic grainstone-rich reservoir analog deposited during high-amplitude ... -
Sedimentology and stratigraphy of the Miocene to Pliocene Mona Reef Complex and its relation with relative sea-level fluctuations
(University of Kansas, 2012-05-31)The Miocene to Pliocene Mona Reef complex was investigated to define facies distribution, identify corals, describe strata geometries, and provide insights on porosity distribution. Two units were identified on the platform ... -
Iron Covering as a Protection Against Magnetization

Geology of the central Little Burro Mountains Grant County, New Mexico
(The University of Kansas, 1961)The Little Burro Mountains are a small fault-block mountain range in central Grant County, New Mexico. Rocks of the Precambrian Burro Mountains batholith are exposed along the southwest scarp of the mountains, and are ... -
STRATAL PATTERNS OF THE WILLIAMS FORK (HUNTER CANYON) FORMATION, PICEANCE BASIN, COLORADO
(University of Kansas, 2010-12-31)The Cretaceous Williams Fork Formation contains stratal packages that represent the final stage of deposition within the Cretaceous Western Interior foreland basin (Colorado). These stratal packages record changes in ... -
Development of a Seismic Snow Streamer and Use of Multi-Offset Reflection for Determining Glacier Ice Properties
(University of Kansas, 2012-12-31)Glaciers and ice sheets are important to climate research due to their role in controlling worldwide weather and temperature patterns as well as their potential impact in sea level rise. Because of this, scientists are ... -
ACTIVE FAULTING AND QUATERNARY SLIP RATES OF THE COLOMBIAN SUB-ANDES
(University of Kansas, 2012-12-31)Active deformation of northwestern South America is the result of the complex interaction between the Caribbean and Nazca plates subducting beneath South America, in sharp contrast to the classic Andean-type margin, south ... -
STRATIGRAPHIC DISTRIBUTION AND PALEOENVIRONMENTAL IMPLICATIONS OF PEDOGENIC FEATURES AND TRACE FOSSILS FROM THE LOWER PERMIAN OF KANSAS
(University of Kansas, 2012-12-31)ABSTRACT Paleosols in the Lower Permian (Asselian-Sakmarian) Council Grove Group from western Kansas, USA, contain numerous pedogenic features, including carbonate nodules (caliche), redoximorphic coloration, rhizoliths, ... -
SEQUENCE STRATIGRAPHY AND CHEMOSTRATIGRAPHY OF AN INCISED VALLEY FILL WITHIN THE CRETACEOUS BLACKHAWK FORMATION, BOOK CLIFFS, UTAH
(University of Kansas, 2012-12-31)A better constraint on the timing and depositional development of the incised valley fill (IVF) of the Desert Member of the upper Cretaceous Blackhawk Formation was needed to help understand the development of incised ... -
Detrital thermochronology of the Alpine foreland basin in Central Switzerland: Insights into tectonic and erosion history of the North Central Alps
(University of Kansas, 2012-12-31)This study systematically integrates zircon U-Pb geochronology and (U-Th)/He low-temperature thermochronology to correlate the Northern Alpine Foreland Basin (NAFB) sediment provenance and the tectonic and thermal evolution ... -
Seismic Attribute Analysis of the Mississippian Chert at the Wellington Field, south-central Kansas
(University of Kansas, 2012-12-31)Mississippian chert reservoirs, important hydrocarbon resources in North America, are highly heterogeneous, typically below seismic resolution and, therefore, present a challenging task for predicting reservoir properties ... -
