The role of long-term tectonic deformation on present day seismicity in the Caribbean and Central America
… spectrum of earthquake types due to its complex tectonic setting comprised of transform zones, young oceanic spreading ridges, and subduction along its eastern and western boundaries. CCAR is, therefore, an ideal setting in which to study the impacts of long-term tectonic deformation on the …

Nature and origin of minerals in anthracite from eastern Pennsylvania
… among mineral authigenesis, coalification, and tectonic deformation. Minerals in anthracite occur as distinct assemblages associated with the following microenvironments: coal matrix, two orthogonal joint sets restricted to coal beds (termed systematic and non-systematic cleat), a third joint …

Mass-transport deposits on Mediterranean continental margins
… on the role of fluid flow, currents activity and tectonic deformation determine a wider view on the construction of the studied continental margins.

Ridge segmentation, tectonic evolution and rheology of slow-spreading oceanic crust
… surface is oceanic crust formed by magmatic and tectonic processes along mid-ocean ridges. Slow-spreading ridges, such as the Mid-Atlantic Ridge, are discontinuous and composed of ridge segments. Segments are thus fundamental units of magmatic accretion and tectonic deformation that control the …

Geomechanical and tectonic investigations into the geologic history of Mars at local, regional, and global scales
… use of geomechanical techniques to investigate tectonic deformation of the lithosphere at local, regional, and global scales. Techniques that have their origins in terrestrial geology are applied to Mars to analyze tectonic deformation of the lithosphere at these scales. At the local, or outcrop …

New structural interpretation, microstructural analyses, and preliminary monazite geochronology of Proterozoic rocks in the central Manzano Mountains, New Mexico
… were multiply deformed during at least three deformation events. D1, D2, D3 of rocks in the Manzano Mountains have all produced movement along the NE striking Monte Largo shear zone (MLSZ). The movement sense within this shear zone is consistently top-to-the-northwest. Analysis of …

Fracture-enhanced porosity and permeability trends in the Bakken Formation, Williston Basin, western North Dakota
… basement-block boundaries in response to varying tectonic stresses and crustal flexure throughout the Phanerozoic. Landsat-derived lineament maps were examined for the area between 47° and 48° north latitude and 103° and 104° west longitude (northern Billings and Golden Valley Counties, and …

Crustal Structure in a Mesozoic Extensional Terrane: The South Georgia Rift and the Epicentral Area of the 1886 Charleston, South Carolina, Earthquake
… reflection profiles have shed light on the tectonic environment of the area. The epicentral area of the 1886 event lies within the South Georgia Rift, a Mesozoic rift terrane. Previous studies have revealed clues to the geologic structure and evolution of this feature. SEISDATA4 is the …

Glacial isostatic adjustment and relative sea level change over the last earthquake cycle in upper Cook Inlet, Alaska, USA
Using observations of land surface deformation, sea level change and geophysical modelling, this thesis considers the interactions of ice mass fluctuations and tectonic deformation over the last great earthquake cycle in south central Alaska. Reconstructions of relative sea level change over the …

Neotectonics Study Along The Frontal Thrust System Of The Fold-Thrust Belt Of Northwest Himalayas, Pakistan
… geometry, geomorphic evolution, and active tectonic deformation of the Himalayan Frontal Thrust System. The first study focuses on the westernmost segment of the Himalayan frontal thrust in the Manzai Ranges. The geologic landscape shows active tectonic features, i.e., stream deflection, …

The kinematics and dynamics of active mountain ranges
This thesis explores the controls on tectonic deformation in and around active continental mountain belts, and comprises three interconnected studies. The first chapter investigates lateral variations in the foreland of the New Guinea Highlands, a young mountain range which sits on the northern …

QUASI STATIC GRAVITY SIGNATURES IN SLOW TECTONIC ZONES: ASSIMILATION OF NOVEL AEROSPACE DATA AND GEOPHYSICAL MODELING
… of the mechanisms that regulate slow rate tectonic deformation in areas where the earthquakes enucleate. 2D thermo-mechanical numerical models are used to simulate the crust-mantle dynamics; in particular, complexities such as compositional stratification of crust-lithosphere system, mantle …

InSAR time series analysis and machine learning for ground subsidence monitoring and susceptibility mapping in Midvaal, South Africa
… MintPy. ISCE PS-InSAR was the most accurate for tectonic deformation monitoring, with minimal errors and stable velocity estimates. In contrast, HyP3 SBAS-InSAR performed well in detecting localised deformations but had higher error margins. Additionally, A semi-automated preprocessing tool, …

The tectonic evolution of the western Tien Shan
Intracontinental deformation usually is a result of tectonic forces associated with distant plate collisions. In general, the evolution of mountain ranges and basins in this environment is strongly controlled by the distribution and geometries of preexisting structures. Thus, predictive models …

The architecture, growth and tectono-stratigraphic significance of rift-oblique lineaments on the NE Atlantic Margin
… basin-wide strike-slip faults and other, non-tectonic origins. Using well-calibrated 2D and 3D seismic data, this study critically assesses the structural, stratigraphic and magmatic evidence for the rift-oblique lineaments in the Faroe-Shetland Basin and Vøring Basin, both located upon the NE …
