Mesozoic rift to post-rift tectonostratigraphy of the Sverdrup Basin, Canadian Arctic

Marine and Petroleum Geology, 2016
Abstract Jurassic-Cretaceous rift successions and basin geometries of the Sverdrup Basin are reconstructed from a review and integration of stratigraphy, igneous records, outcrop maps, and subsurface data. The rift onset unconformity is in the Lower Jurassic portion of the Heiberg Group (approximately 200–190 Ma).

Dnieper Donets Rift Basin, Ukraine - Post-rift evolution

Proceedings, 1996
The investigations were grounded on complex interpretation of regional seismic profiles, well data and numeric modelling. The main stage of the rifting in the DD basin lasted 7-10 My during the Frasnian and Fanennian stages of the Late Devonian. Post-rift Carboniferous, Permian and Mesozoic sediments cover the rift flanks and increase in thickness ...

Dynamic processes controlling evolution of rifted basins

Earth-Science Reviews, 2004
The extension of the lithosphere, controlling the development of rifted basins, is driven by a combination of plate-boundary forces, frictional forces exerted on the base of the lithosphere by the convecting asthenosphere and deviatoric tensional stresses developing over upwelling branches of the asthenospheric convection system. Although mantle plumes

Submarine slope processes in rift-margin basins, Miocene Suez Rift, Egypt [PDF]

open access: possibleGeological Society of America Bulletin, 2012
New, high-resolution lithofacies data from hanging-wall Miocene synrift (Rudeis Formation) exposures of the eastern Suez Rift margin, Egypt, reveal a submarine slope depo si tional system dominated by coarsegrained (pebble), heterogeneous, lenticular beds, formed by coalescing turbidity currents, slumps, and debris fl ows deposited on deforming ...

Orthogonal to oblique rifting: effect of rift basin orientation in the evolution of the North basin, Malawi Rift, East Africa

Basin Research, 2007
ABSTRACTThe East African Rift system has long been considered the best modern example of the initial stages of continental rifting. The Malawi Rift is characteristic of the western branch of the East African Rift system, composed of half‐grabens of opposing asymmetry along its length.

Rift basins and supradetachment basins: intracontinental extensional end‐members

Basin Research, 1995
AbstractTwo end‐members characterize a continuum of continental extensional tectonism: rift settings and highly extended terrains. These different styles result in and are recorded by different extensional basins. Intracontinental rifts (e.g. East Africa, Lake Baikal) usually occur in thermally equilibrated crust of normal thickness.

The rifting of the Tyrrhenian Basin

Geo-Marine Letters, 1987
An evolved system of North-South trending rotational normal faults records the direction of a stretching event on the Tyrrhenian Sea continental margins. Evolutionary stages of a typical rifted basin are recognized in the Tyrrhenian Sea through the interpretative analysis of seismic data, A major unconformity marks the end of a quite short (Tortonian ...
