Fault rock evolution and fluid flow in sedimentary basins
Structural studies have been undertaken in two extensional fault regimes associated with post-Caledonian basin-forming events in northern Scotland. A combination of detailed mapping and microstructural analysis has revealed the deformation processes and mechanisms involved in fault rock evolution …

Expressions of Mantle Dynamics in Landscapes and Sedimentary Basins
… be obtained from fluvial landscapes and from sedimentary basins. I first investigate the growth of the Anatolian Plateaux. Elevated Miocene marine sedimentary deposits distributed across Anatolia indicate that significant uplift has occurred during Neogene and Quaternary times. However, the …

Numerical evaluation and analysis of the occurrence of earth fissures in faulted sedimentary basins
This dissertation describes the occurrence of pumping-induced earth fissures associated with quaternary faulting using numerical simulations. The Eglington Fault located in Las Vegas valley has been selected as the prototype fault described herein. The finite-element software program ABAQUS is used …

Compaction-Driven Groundwater Flow and Heat Transfer in Intracratonic Sedimentary Basins and Genesis of the Upper Mississippi Valley Mineral District (Hydrology, Migration, Petroleum, Ore Deposits, Numerical Models)
… flow and associated heat transfer in evolving sedimentary basins. A calculation of compaction-driven flow during evolution of an idealized intracratonic sedimentary basin including a basal aquifer predicts slow groundwater movement over long time periods. Fluids in shallow sediments tend to …

An integrated approach to groundwater exploration using remotely sensed imagery and geophysical techniques: a case study in the Archean basement and Karoo sedimentary basins of Limpopo Province of South Africa
… basement rocks, Soutpansberg volcano-sedimentary succession and subsidiary basins of the main Karoo young sedimentary cover. In general, the groundwater potential of a region is a function of factors such as lithology, lineaments, slope, climate and land use/ land cover. Thus, the …

Quantitative Models of Fluid Flow, Chemical Reaction, and Stable Isotopic Fractionation and Their Application to Sediment Diagenesis and Hydrothermal Alteration
… through temperature and pressure gradients in sedimentary basins. I incorporate chemical reaction into a transient model of groundwater flow equations that describes heat transfer and solute transfer. The model is formulated and solved in geologic-time and basin distance scales, and can be …

Building Velocity Models for Steep-Dip Prestack Depth Migration through First Arrival Traveltime Tomography
… have not been imaged as reflectors outside of sedimentary basins; to do so requires appropriate data acquisition, prestack depth migration, and an excellent seismic velocity model. Poststack time migrated seismic images, normal moveout velocity analysis, well logs, and other geologic …

Compression behavior of smectitic vs. illitic mudrocks
… has been observed globally in many deep water sedimentary basins. One of the possible mechanisms for overpressure is the smectite-to-illite (S-I) transformation. During the transformation, the basal spacing of the smectite layer reduces. The interlayer water is released into pore space, causing …

Joint modeling receiver functions and autocorrelograms to estimate crustal structure in the presence of deep sediments.
… function methodologies for application to sedimentary basins, which is useful because basin structure introduces complexity to the receiver functions. First, we consider vertical autocorrelograms along with P receiver functions. The same interfaces that generate Ps conversions also reflect …

Controls on long-term drainage development of the Carboneras Basin, SE Spain
… Cordillera, was one of the last of a series of sedimentary basins which underwent transition from marine to continental conditions during the Plio/Pleistocene in this region. The basin is still tectonically active, controlled by surface uplift of the basin, differential uplift of the Sierra …

Empirical nonlinear site response applicable to Greater Vancouver, British Columbia
… located at the edges or deeper center of sedimentary basins in Mexico City, the Kanto basin and Anchorage with available weak-to-strong motion recordings that have similar linear site response to Greater Vancouver to constrain the expected nonlinear soil response for future large …

Igneous intrusions and thermal evolution in the Raton Basin, CO-NM: contact metamorphism and coal-bed methane generation
… may be very important for methane generation in sedimentary basins.

Slope and bifurcation on braided distributive fluvial systems
… distributive fluvial systems (DFS) in active sedimentary basins, which have the highest likelihood of being preserved. DFS are sediment deposits that occur when rivers exit the confinement of mountain valleys and become laterally mobile in broad sedimentary basins. They are characterized by a …

Assessing the mechanical microstructure of shale by nanoindentation : the link between mineral composition and mechanical properties
Shale is a multi-phase, multi-scale sedimentary rock that makes up 75% of the earth's sedimentary basins and is especially critical in petroleum engineering applications. At macroscopic scales, shales possess a diverse set of possible compositions, resulting in a diverse set of mechanical …

THE SEDIMENT AND CRUSTAL STRUCTURE OF THE SOUTHEASTERN UNITED STATES
… the ground shaking hazard posed by widespread sedimentary basins remains poorly quantified. P-to-S converted waves, analyzed through the receiver function technique, enable detailed imaging of lithospheric structure, but suffer from contamination in sedimented regions. Therefore, I implement a …
