Sedimentary organic matter diagenesis : oxidative transformations and dynamics upon pyrolysis.
(2017-07-07)The organic matter fraction preserved in ancient sediments is the largest carbon pool on earth, and holds immense importance in the context of global biogeochemical cycling and as petroleum source rock. This dissertation ... -
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 ... -
Seismo-lineament analysis of selected earthquakes in the Tahoe-Truckee area, California and Nevada.
(, 2012-08-08)Focal mechanism solutions from 29 M≥3 earthquakes recorded between 1966 and late 2009 in the Tahoe-Truckee area, California and Nevada, were used to establish a preliminary spatial correlation between these earthquakes and ... -
Seismo-lineament analysis of the Malibu Beach quadrangle, Southern California.
(2007-12-04)The Santa Monica Mountains are a young, structurally active mountain range within southern California. The purpose of this study was to map seismogenic faults within the Malibu Beach quadrangle. Using available earthquake ... -
The sequence stratigraphic evolution of the Sturgeon Lake bank, central Alberta, Canada and its regional implications.
(2006-05-29)Sturgeon Lake South (SLS) is an isolated Devonian (Late Frasnian) platform located within the Western Canada Sedimentary Basin (WCSB). Stratigraphic correlation of the Leduc Formation across the WCSB reveals a dominantly ... -
Sp receiver function imaging of a passive margin : transect across Texas’s Gulf Coastal Plain.
(, 2013-09-24)A Sp receiver function common conversion point (CCP) stacked image beneath Texas Gulf Coast Plain (GCP) reveals anomalies that may be detached lower crust sinking into the mantle. The detached crust may have resulted from ... -
Spatial correlation of selected earthquakes with the Dog Valley Fault in northern California using LiDAR and GPS data.
(2017-07-28)The 1966 M6.0 Truckee earthquake has a reported location of 39.438°N 120.160°W at ~10 km depth (Ryall et al., 1968), ~5 km southwest of the Stampede Dam, an earth-fill structure built in 1970 to impound 226,500 acre-feet ... -
Structural analysis of the Criner Hills, South-Central Oklahoma.
(2006-07-31)It has been suggested that there may have been Quaternary displacement along the Criner Hills Fault in South-Central Oklahoma. The Criner Hills Fault is generally on-trend with the active Meers Fault, which has led some ... -
The stratigraphic controls on development potential within the Lower Cretaceous glauconitic member sandstone, Jenner Field area, Southern Alberta, Canada.
(2017-08-02)The Glauconitic Member of the Lower Cretaceous Upper Mannville Group consists of incised valley filling multi-story fluvial quartzose sandstone deposits that accumulated during a marine transgression. This study delineates ...
