Fault analyses in petroleum traps have grown along two distinct and successive lines of thought: (1) fault closures and (2) fault-rock seals. Through most of the last century, geometric closure of fault traps and reservoir seal juxtaposition by faults were the focus of research and industrial application. These research and applications were made as structural geology developed quantitative methods for geometric and kine- matic analyses of sedimentary basins, and plate tectonics offered a unified tool to correlate faults and basins on the basis of the nature of plate boundaries to produce stress.

Journal of Coastal Research, 00(0), 000–000. Coconut Creek (Florida), ISSN 0749-0208. This study investigates the relationship between faulting, subsidence, and land loss in coastal Louisiana. A methodology that integrates three-dimensional (3D) seismic data, well logs, high-resolution topographic mapping (LIDAR), and historical aerial photography is successfully developed to identify fault-related geomorphic changes in southwestern Louisiana’s Chenier Plain. Analysis of a 3D seismic survey and well logs reveals the presence of 10 normal faults that form an east-west graben in the middle of the study area.

This thesis was written with the intent of first classifying the types of extensional basins and then describing their evolution. The understanding of the basin dynamics throughout their history will help in interpreta- tions of past and present day tectonic regimes. Final chapters discuss characteristics and dynamics of foreland basins including potential inversion of pre-existing extensional basins. ii Chapter 1 Classification of rift systems: Basics 1.1 Continental Rifts Continental rifts are areas where extension of the continental lithosphere leads to a subsid- ing basin.It is broken by several normal faults or several sets of normal faults, which can lead to either passive or active upwelling of the hot asthenospheric material underneath the area of the rift (Allen & Allen, 1990, 2005; Brun, 1999).

The study was conducted taking measure- ments of deformation features such as fractures and deformation bands on multiple 1D scanlines along fault walls. The resulting datasets are used to plot the frequency distribution of deformation features and to constrain the geometrical width of the damage zone for the studied faults. The damage-zone width of a single fault is con- strained by identifying the changes in the slope of cumulative plots made on the frequency data. The cumulative plot further shows high deformation frequency by a steep slope (inner damage zone) and less deformation as a gentle slope (outer damage zone). Statistical distributions of displacement and damage-zone width and their relationship are improved, and show two-slope power-law distributions with a break point at c. 100 m displace- ment. Bleached sandstones in the studied siliciclastic rocks of Utah are associated with a higher frequency of deformation bands and a wider damage zone compared to the unbleached zone of similar lithology.

The deformation mechanism of fault in brittle and ductile mudstone caprock is different, which leads to the formation of different types of fault zone structure. Different methods are required to evaluate the sealing mechanism of those fault zones. Based on the caprock deformation mech- anism, fault sealing mechanism, quantitative evaluation method of vertical fault sealing capacity is put forward in this study. Clay smear is formed in the process of plastic deformation and its continuity con- trols the sealing capacity of fault.

  • Fault Geometry and Kinematics Within the Terror Rift, Antarctica THESIS
    Fault Geometry and Kinematics within the Terror Rift, Antarctica THESIS Presented in Partial Fulfillment of the Requirements for the Degree Master of Science in the Graduate School of The Ohio State University By William B. Blocher Graduate Program in Earth Sciences The Ohio State University 2017 Master's Examination Committee: Dr. Terry Wilson, Advisor Dr. Thomas Darrah Dr. Derek Sawyer Copyrighted by William B. Blocher 2017 Abstract The Terror Rift is the youngest expression of the intraplate West Antarctic Rift System that divides the Antarctic continent. Previous studies of the Terror Rift have ascribed a variety of interpretations to its structure, and especially to the regional anticline known as the Lee Arch, which has been explained as a transtensional flower structure, a rollover anticline, and as the result of magmatic inflation. Fault mapping and the documentation of stratal dips in this study have revealed a Terror Rift structure characterized by north-south folds and a complex distribution of faults. Nearly all faults have normal sense dip separation. A continuous zone of west-dipping faults with relatively high-magnitude normal separation are interpreted to be the border fault system defining the eastern margin of Terror Rift. Reconstruction of listric ramp-flat geometry of this border fault system explains intrarift fold and fault patterns well. Zonation of structures indicates that the listric rift detachment faults are segmented along the rift axis. This new model for rift structure indicates orthogonal rift extension in the ENE- WSW direction, with low strains of <10% calculated from bed-length balancing. i Acknowledgments To my advisor, Dr.

  • Controls on Structural Styles and Decoupling in Stratigraphic Sequences
    Manuscript submitted to Journal of Structural Geoloy 1 Controls on structural styles and decoupling in stratigraphic sequences 2 with double décollements during thin-skinned contractional tectonics: 3 insights from numerical modelling 4 Qingfeng Meng*1, David Hodgetts 5 School of Earth and Environmental Sciences, University of Manchester, M13 9PL, UK 6 Abstract 7 Six series of particle-based numerical experiments were performed to simulate thin-skinned 8 contractional tectonics in stratigraphic sequences with double décollements during horizontal 9 shortening. The models were assigned with varying rock competence, depth and thickness of the 10 upper décollement, which resulted in significantly different styles of deformation and decoupling 11 characteristics above and below the upper décollement. The models composed of the least 12 competent material produced distributed sinusoidal detachment folds, with many shallow 13 structures profoundly decoupled from the deep-seated folds. The models composed of a more 14 competent material are dominated by faulted, diapir-cored box folds, with minor disharmonic folds 15 developed in their limbs. Differently, the results of models composed of the most competent 16 material are characterised by localised piggyback thrusts, fault-bend folds and pop-up structures 17 with tensile fractures developed in fold hinges. Depth of the upper décollements also plays an 18 important role in controlling structural decoupling, i.e. the shallower the upper décollements, the 19 higher the degree of decoupling becomes. Thicker upper décollements can provide sufficient 20 mobile materials to fill fold cores, and contribute to the formation of secondary disharmonic folds, 21 helping enhance structural decoupling. Our modelling results are comparable to the structural 1 *Corresponding author.
