Seismic stratigraphy and burial history for source and reservour prediction in the Luderitz basin, license blocks 2412B and 2413B, offshore Namibia
… African passive margin that evolved during continental break-up and subsequent opening of the South Atlantic during the late Jurassic and Cretaceous. It is considered as a hydrocarbon frontier that is largely under-explored with only one well (2513/8-1) drilled since the wake of hydrocarbon …

Formation and evolution of the eastern Black Sea basin: constraints from wide-angle seismic data
Rifted continental margins and extensional basins, provide lasting records of the processes that occur during continental break-up and initial spreading. The eastern Black Sea (EBS) basin provides a good setting to study the development of continental margins, because of ongoing sedimentation …

U-Pb geochronology and structural geology across major shear zones of the Southern granulite terrain of India and organic carbon isotope stratigraphy of the Gondwana coal basins of India : their implications for Gondwana studies
… U-Pb geochronology. Because Peninsular India occupied a central position in Gondwana, this work bears on reconstruction models of central Gondwana between circa 600 Ma and 200 :f1,a. The second part of the thesis (Chapter 6) tests the use of organic carbon isotopes as a chemostratigraphic tool to …

Supercontinental Inheritance and its Influence on Supercontinental Breakup: The Central Atlantic Magmatic Province and the Breakup of Pangea
… igneous province (LIP) that coincides with the breakup of the supercontinent Pangea. Major and trace element data, Sr-Nd-Pb radiogenic isotopes, and high-precision olivine chemistry were collected on primitive CAMP dikes from Virginia (VA). These new samples were used in conjunction with a …

Tectonic and magmatic processes during extension in planetary lithospheres : rifting, spreading, delamination, and recycling on Earth and Venus
… responds to driving forces such as the upwelling or downwelling of material in the mantle, especially for extensional systems. On Earth, the processes underpinning continental break-up are poorly understood despite decades of study. In this dissertation, I present a synthesis of …

Thermo-tectonic record of hyperextension, structural inversion, and foreland basin evolution of the eastern and central Pyrenees
… the thermal and structural evolution of continental rift systems, and the role of pre-existing crustal architecture on orogenesis and foreland basin development. This work constrains the Early Cretaceous hyperextension history along the Iberia-European margin and how rift inheritance …

A Geodynamic Investigation of Continental Rifting and Mantle Rheology: Madagascar and East African Rift case studies
Continental rifting is an important geodynamic process during which the Earth's outer-most rigid shell undergoes continuous stretching resulting in continental break-up and theformation of new oceanic basins. The East African Rift System, which has two continentalsegments comprising largely of the …

Surface heat flow and lithospheric thermal structure of the northwestern Arabian Plate

The Structural Evolution of the Faroe Islands, NE Atlantic Margin
… through to the Cenozoic, which record the build up to plate separation and formation of the North Atlantic Ocean. Existing models for this invoke broadly NW-SE extension within the basins, which are segmented by regional-scale NW-SE trending strike-slip lineaments, which are commonly termed …
