Distribution of post-Last Glacial Maximum Sedimentary Deposits in the Amundsen Sea, Antarctica, from Subbottom Seismic Profiles
… as processes that are occurring today. Subbottom profiles collected across the Amundsen Sea Embayment during the austral summers of 2019 and 2020 reveal sediment that has been delivered from two major glaciers: Thwaites and Pine Island. Sediments transported by Thwaites and Pine Island Glaciers …

The geology of the diamondiferous inner shelf off Namaqualand between Stompneus Bay and White Point just north of the Buffels River
… morphology, compiled from high-resolution seismic profiles, shows erosional features in the bedrock surface which indicate potentially diamondiferous areas. Gently sloping (1°) wave-abraded terraces occur at -14m to -lam, -22m to -28m, -33m to' -40m and -44m to -53m. Palaeo-channels of the …

Geohistory of the Central Anatolian Plateau southern margin (southern Turkey)
… easternmost Mediterranean realm. Using industry seismic reflection data we correlate 34 seismic profiles with corresponding exposed units in the Adana Basin. The time-depth conversion of the interpreted seismic profiles allows us to reconstruct the subsidence curve of the Adana Basin and to …

Colapso gravitacional e estruturação da seção marinha da bacia da Foz do Amazonas no contexto de múltiplos níveis de destacamento
… Thrust structures, imaged by 2D multichannel seismic profiles, were driven by gravity in a linked extensional-contractional system gliding on weak levels, and driven by sedimentary loading and by the bathymetric slope. Extension is characterized by both basinward- and landward-dipping normal …

Siesmic Stratigraphy of Upper Pleistocene gravel and holocene mudbelt deposits between wreck point and the kamma river on the western shelf of South Africa
… at approximately 29º20.00′S, based primarily on seismic stratigraphy. The high resolution airgun seismic survey performed by De Beers Marine during 1998 was interpreted based on seismic stratigraphic principles and the chronology of the seismic profiles was based on correlation to …

Processing of DAS and geophone VSP data from the CaMI Field Research Station
… The acquisition and processing of Vertical Seismic Profiles (VSP) were undertaken for this thesis. More specifically, the analysis of three different surveys: a walk around VSP for azimuthal anisotropy analysis, zero offset VSPs to test the emerging DAS technology and walk-away VSP to obtain …

The marine geology of Walker Bay, off Hermanus, SW Cape, South Africa
… 1990. The data include side-scan sonar images, seismic profiles, seabed samples and observations by a Remotely Operated underwater Vehicle (ROV). Four sonograph facies were identified, based on their distinctly different reflectivity patterns. Using the seabed samples and R.O.V. observations, …

Crustal accretion and evolution at slow and ultra-slow spreading mid-ocean ridges
… Indian Ridge (SWIR) (full rate, 14 km/Myr). Seismic refraction data collected along the rift valley and flanking rift mountains of the OH-1 segment (35ʻN) at the MAR show that the entire crustal section is constructed within a zone that is less than 5 km wide. Shallow-level hydrothermal …

Nonlocalized faulting in a thick lithosphere : application to lunar contraction
… We use elastic constants inferred from lunar seismic profiles, and use a finite element code to model the response of this lithosphere to contraction. We find that fault localization and propagation are strongly affected by the thickness of the lithosphere. A thin lithosphere promotes fault …

Structural geometry of the frontal Ouachitas-Arkoma basin transition zone in Western Arkansas
… in Arkansas. This study uses depth-converted 2-D seismic reflection profiles and well log data to clarify the subsurface structure and establish the presence or lack of triangle zone elements within the accommodation zone between the Choctaw Fault and Ross Creek Fault in north-central Scott …

Fractal analysis of topography and structure across the Appalachian foreland of West Virginia
… analysis was conducted on topographic relief and seismic reflection travel time data in the state of West Virginia to determine the potential influence of subsurface structure on surface topography. Seismic travel-times digitized from two east-west seismic profiles and topographic relief extracted …

Subsurface structural geology of the eastern part of the Büyük Menderes Graben, western Turkey: implications for structural evolution of the Büyük Menderes and Alasehir Grabens
… bordered by two major approximately E-W trending seismically active grabens: the Alasehir and Büyük Menderes Grabens (BMG). Seven depth-converted 2-D seismic reflection profiles and well log data from one well are used to delineate the geometry of the subsurface structural features and the …

Neogene seismotectonics of the south-central Chile margin : subduction-related processes over various temporal and spatial scales
… and their possible feedbacks. Most of the seismic energy on Earth is released by earthquakes in subduction zones, like the giant 1960, Mw 9.5 event in south-central Chile. However, the segmentation mechanisms of surface deformation during and between these giant events have remained poorly …
