Stratigraphy, Diagenesis, And Petroleum Geology Of The Smackover Formation, Southwest Alabama., William James Wade
Stratigraphy, Diagenesis, And Petroleum Geology Of The Smackover Formation, Southwest Alabama., William James Wade
LSU Historical Dissertations and Theses
The sequence stratigraphic framework of the Smackover Formation and other Jurassic strata in southwest Alabama is delineated, with the objective of eventual correlation of equivalent sequences across the northern Gulf. Additionally, geologic controls on the diagenesis of organic matter in the Smackover Formation are examined, in order to better understand organic-inorganic interaction and hydrocarbon evolution during burial. Jurassic systems tracts of southwest Alabama differ significantly from those of the north central Gulf in that they show profound influence of antecedent topography, consequent large continental clastic influx, and a subsidence history less influenced by thermal cooling. Norphlet siliciclastics constitute a continental …
Tectonic Implications Of Fission-Track Thermochronology And Amphibole Thermobarometry Studies Of The Northern Peninsular Ranges Batholith, Southern California., Peter Gillham George
Tectonic Implications Of Fission-Track Thermochronology And Amphibole Thermobarometry Studies Of The Northern Peninsular Ranges Batholith, Southern California., Peter Gillham George
LSU Historical Dissertations and Theses
Fission-track data from the San Jacinto Mountains and the Palomar Mountain-Escondido study area indicate that the Late Cretaceous history of the Peninsular Ranges batholith is marked by a series of major cooling events. Coupled with geobarometry measurements and field observations, these data allow for a greater understanding of the nature and timing of both local and regional tectonic events. In the eastern Peninsular Ranges, west-vergent thrusting along the Santa Rosa mylonite belt at $\sim$99-94 Ma was followed by major extensional faulting between $\sim$94 and 92 Ma. Amphibole geobarometry of mylonites indicate that $\sim$10-18 km of crustal thickening occurred as a …
Geologic And Physical Processes At A Gulf Of Mexico Tidal Inlet, East Pass, Florida., Andrew Morang
Geologic And Physical Processes At A Gulf Of Mexico Tidal Inlet, East Pass, Florida., Andrew Morang
LSU Historical Dissertations and Theses
East Pass, a tidal inlet located in the Florida Panhandle between Pensacola and Panama City, connects Choctawhatchee Bay to the Gulf of Mexico. A three-phase model has been developed which describes the behavior of East Pass inlet during the last 120 years, based on wave, current, tide, bathymetric and shoreline data, and on historical records. The first phase (pre-1928) is of spit development and breaching. This phase covers the period when the pass was oriented in a northwest-southeast direction between Choctawhatchee Bay and the Gulf. From 1928 to 1968, the second phase was characterized by a stable throat position but …
Origin Of A Coarse-Grained Shallow Marine Sandstone Complex: The Coniacian Tocito Sandstone, Northwestern New Mexico. (Volumes 1 And 2)., Gregory Wayne Riley
Origin Of A Coarse-Grained Shallow Marine Sandstone Complex: The Coniacian Tocito Sandstone, Northwestern New Mexico. (Volumes 1 And 2)., Gregory Wayne Riley
LSU Historical Dissertations and Theses
Study of the Coniacian Tocito Sandstone, one of the shale-encased, shallow marine sandstone complexes in the Cretaceous Western Interior Basin, indicates that transport of coarse sediment to distal marine locations was accomplished by an increase in the efficiency of the marine dispersal system (tidal currents). Enhanced tidal currents were a consequence of bathymetric variations formed by uplifts along the pre-existing Four Corners Lineament system. The Tocito Sandstone forms an entirely marine, progradational-transgressive sequence and overlies an unconformity localized along uplifted submarine highs. The lower progradational strata represent the marine portion of a tide-dominated delta that prograded into a tectonically-created "embayment", …
