Late extension of a passive margin coeval with subduction of the adjacent slab: The Western Alps and Maghrebides files

open access: yesBSGF - Earth Sciences Bulletin, 2023
The evolution of the Alpine Tethys margins during the beginning of the African-Eurasian convergence was little studied compared to their evolution during the post-Pangea rifting and oceanic expansion, i.e., from the Early Jurassic to the early Late ...

Oblique rifting: the rule, not the exception [PDF]

open access: yes, 2018
Movements of tectonic plates often induce oblique deformation at divergent plate boundaries. This is in striking contrast with traditional conceptual models of rifting and rifted margin formation, which often assume 2-D deformation where the rift ...

Is There a Speed Limit for the Thermal Steady‐State Assumption in Continental Rifts?

open access: yesGeochemistry, Geophysics, Geosystems, 2021
The lithosphere is often assumed to reside in a thermal steady‐state when quantitatively describing the temperature distribution in continental interiors and sedimentary basins, but also at active plate boundaries.

Distribution of Cambrian Source Rock Controlled by the Inherited Paleotopography on the Precambrian Basement in the Tarim Basin, NW China

open access: yesFrontiers in Earth Science, 2022
The Cambrian source rock is a key indicator that will guide future hydrocarbon explorations in ultra-deep strata. Despite its importance, the characteristics of paleotopography on the Precambrian basement and the distribution of source rocks above it ...

Why is Africa rifting? [PDF]

open access: yes, 2016
Continental rifting has a fundamental role in the tectonic behaviour of the Earth, shaping the surface we live on. Although there is not yet a consensus about the dominant mechanism for rifting, there is a general agreement that the stresses required to ...

LONG-LIVED STRUCTURAL ENSEMBLES OF THE EAST EUROPEAN PLATFORM. Article 2. THE STRUCTURE OF THE TOP OF THE BASEMENT

open access: yesИзвестия высших учебных заведений: Геология и разведка, 2018
The basement’s top tectonics of the East European platform (EEP) has been considered on the basis of the modern mapping data. The importance of the long-lived tectonic zones that form the vortex megastructure has been justified.Their Riphean — early ...

The break-up of continents and the formation of new ocean basins

open access: yes, 2002
Rifted continental margins are the product of stretching, thinning and ultimate break-up of a continental plate into smaller fragments, and the rocks lying beneath them store a record of this rifting process.
