The Jurassic Norphlet Formation of the deep-water Eastern Gulf of Mexico : a sedimentologic investigation of aeolian facies, their reservoir characteristics, and their depositional history.
(2011-01-05)This study defined the sedimentary facies, reservoir architecture, and depositional history of the Jurassic aeolian Norphlet Formation in the deep-water Eastern Gulf of Mexico. Seven depositional facies were identified ... -
Linking onshore and offshore data to find seismogenic faults along the Eastern Malibu coastline.
(2007-12-04)The Santa Monica Mountains form part of the structurally active southern edge of the Transverse Ranges Province. The purpose of this research is to identify and characterize potentially seismogenic faults in onshore and ... -
Lithofacies heterogeneity, fluvial style variations, and floodplain vegetation distributions : deposition and diagenesis of the Chinle Formation at Petrified Forest National Park, Arizona.
(, 2013-05-15)The Upper Triassic Chinle Formation in the Petrified Forest National Park (PFNP) was evaluated using sedimentologic, stratigraphic, paleopedologic and petrographic criteria. The study interval, which includes the Blue Mesa ... -
Magnetic investigation of the continental-oceanic crustal boundary ; northern Gulf of Mexico.
(, 2012-11-29)Current mapping of magnetic intensity data shows that the Gulf Coast magnetic anomaly is not one anomaly but two distinct anomalies, with one portion trending parallel to the margin before curving northward through central ... -
Mapping the distribution of methane hydrate beneath Woolsy Mound, Mississippi Canyon Block 118, Gulf of Mexico.
(, 2014-01-28)An active methane vent (Woolsey Mound) in Mississippi Canyon Block 118 (MC118), Gulf of Mexico, has been a focus of persistent research. This vent area contains both active and dormant vents and blocks of methane hydrate ... -
Methods of determining stream setback corridors in urban watersheds from remotely sensed data in the Dallas metropolitan area, Texas.
(2010-02-02)Bank stability in urbanized streams is worsening in response to increased runoff, causing unprecedented stream erosion. Eroding banks pose a serious threat to existing structures prompting cities to create buffer zone ... -
Modeling channel erosion in cohesive streams of the Blackland Prairie, Texas at the watershed scale.
(2008-10-02)Stream bank erosion is a product of submerged and subaerial processes. The goal of this research was to assess the application of the submerged jet test to predict erosion of cohesive stream banks in the Blackland Prairie ... -
Multi Objective Optimization for Seismology (MOOS), with application to the Middle East, the Texas Gulf Coast, and the Rio Grande Rift.
(2016-03-24)We develop and apply new modeling methods that make use of disparate but complementary seismic “functionals,” such as receiver functions and dispersion curves, and model them using a global optimization method called “Very ... -
Paleosols as an indicator of ancient landscapes, climates and stratal response during the Triassic: the Salt Anticline Region of Utah.
(2006-05-29)Modern soils are excellent indicators of environmental conditions, and paleosols can be used as proxy for past conditions. This dissertation documents the response of Triassic paleosols and fluvial sediment accumulation ... -
Petrophysical facies mapping of the Pennsylvanian Cline Shale, Midland Basin, West Texas.
(2015-07-31)The Cline Shale is a Pennsylvanian unconventional shale resource play located in the Midland Basin, west Texas. This study evaluates the depositional, stratigraphic and petrologic controls on Cline Shale reservoir quality ... -
Quantifying the structural relationship of leaf mass and petiole width of extant ferns : developing a proxy for fossil applications.
(, 2012-08-08)This study developed a biomechanical model of leaf trait relationships in fern leaves. A common plant relationship is positive covariance between petiole width (PW) and leaf mass (LM). When LM and PW are area-normalized, ... -
Regional reservoir characterization and sequence stratigraphy of the Jean Marie Member of the Redknife Formation, northern British Columbia.
(, 2012-11-29)The Upper Devonian Jean Marie Member of the Redknife Formation in northern British Columbia is an extensive carbonate shelf complex. Porous stromatoporoid boundstones are the primary gas reservoirs, and are stratigraphically ... -
Reservoir assessment of late Devonian Kakisa Formation, northeastern British Columbia, Canada.
(, 2013-05-15)The Late Devonian Kakisa Formation of northeastern British Columbia, Canada is a high energy, aggradational, discontinuous carbonate bank complex that is composed of three distinct allocycles designated the “Upper”, “Middle”, ... -
Rise of the Givetian (385 Ma) Forests, Northern Appalachian Basin, Catskill State Park, New York, U.S.A.
(Society for Sedimentary Geology (SEPM), 2010)Forestation on Earth may have profoundly changed fluvial sedimentary patterns, increased the release of bio-limiting nutrients to marine systems and increased the consumption of atmospheric CO₂ through biologic productivity ... -
Seismic analysis of a slab tear in the Northeast Caribbean.
(, 2013-09-24)Active tectonic regions where plate boundaries transition from subduction to strike-slip can take several forms, such as triple junctions, acute and obtuse corners. The Caribbean-North American plate boundary is one such ... -
Seismic anisotropy in Texas and Oklahoma and its relationship to tectonic events that shaped southern Laurentia.
(, 2013-09-24)We present new shear wave splitting measurements of approximately 1500 SKS phases recorded at 176 broadband seismic stations deployed in Texas and Oklahoma. SKS splitting on the North American (NA) craton show NE-SW fast ... -
Seismic tomographic imaging reveals possible lithospheric erosion beneath Trans-Pecos Texas and Southeastern New Mexico.
(, 2011-12-19)Results from the 1999-2001 La Ristra array revealed a fast seismic velocity anomaly beneath the Rio Grande rift, attributed to a lithospheric “drip” into the mantle, perhaps due to edge-driven convection. To investigate ... -
Seismic Vp & Vs tomography of Texas and Oklahoma with a focus on the Gulf Coast margin.
(, 2013-09-24)We present new 3D seismic tomography velocity models with data from 326 stations, located in Texas, Oklahoma and New Mexico, which utilized 537 seismic events. Tomography results on the North American (NA) craton show a ... -
