Low temperature alteration of the ocean crust: a study of hydrothermal alteration of basalts from near the Australia Antarctic Discordance of the Southeast Indian Spreading Ridge
(Texas A&M University, 2002)
The nature of long term, low temperamre hydrothermal alteration of the ocean crust has remained elusive, due mainly to the limited scope of previous studies, which used single or a very few 011 holes and samples representing ...
Palynology and Paleoecology of the Lake Somerville spillway section, Late Eocene Manning Formation (Jackson Group), east-central Texas
(Texas A&M University, 2000)
Analysis of lignites, freshwater and marine siliciclastic sediments from the Lake Somerville spillway section (Late Eocene, Jackson Group, Manning Formation) yielded a diverse assemblage of terrestrial palynomorphs including ...
Syn-collisional delamination in convergent orogens: insights from lithospheric buoyancy and physical modeling
(Texas A&M University, 2002)
Delamination of the lower crust and lithospheric mantle has occurred in several orogens during convergence, most notably the Alps and Pyrenees. The factors responsible for initiating the delamination are not clear. Some ...
Internal structure of the Kern Canyon Fault, California: a deeply exhumed strike-slip fault
(Texas A&M University, 2002)
Deformation and mineral alteration adjacent to a 2 km long segment of the Kern Canyon fault near Lake Isabella, California are studied to characterize the internal structure of the fault zone and to understand the development ...
Effects of burial history, rock ductility and recovery magnitude on inversion of normal faulted strata
(Texas A&M University, 2001)
Inversion of normal faults at different burial depths is studied using physical models constructed with rock and deformed at confining pressure. Models consist of a 1 cm thick limestone layer above a fault dipping 70° in ...
Paleogene cooling (55-30 MA) as inferred from oxygen isotope variation within mollusc shells
(Texas A&M University, 2001)
Paleogene cooling (c. 50-30 Ma) started sometime in the early-middle Eocene. This was a time when high-latitude and deep-sea temperatures were significantly warmer than today. This cooling culminated during the earliest ...
The effects of lithology and initial fault angle in physical models of fault-propagation folds
(Texas A&M University, 2001)
Experimentally deformed physical rock models are used to examine the effects of changing mechanical stratigraphy and initial fault angle on the development of fault-propagation folds over a flat-ramp-flat thrust geometry. ...
An inverse scheme for sensitivity and uncertainty analysis in basin modeling: the resolution limits of Easy%Ro
(Texas A&M University, 2000)
One of the major contributors to uncertainties in basin modeling arises from the determination of the parameters necessary for reconstructing the thermal history due to the importance of the thermal maturity in evaluating ...
Petrological and petrophysical causes for porosity reduction by bitumen plugging, Uwainat limestone (Middle Jurassic), Dukhan field, Qatar
(Texas A&M University, 2002)
The Uwainat Member at Dukhan field was deposited on a ramp and it represents depositional environments ranging from subtidal, protected shallow-marine to outer ramp environments. The subtidal, protected shallow-marine ...
Using fluid buffering equilibria to determine values of H₂O activity: an example from the amphibole-bearing spinel lherzolites of Caussou, French Pyrenees
(Texas A&M University, 2001)
Samples were collected from the Caussou peridotite in the French Pyrenees. This peridotite represents a portion of the Earth's upper mantle. These samples contain the minerals olivine, clinopyroxene, orthopyroxene, and ...
