LONG-LIVED STRUCTURAL ENSEMBLES OF THE EAST EUROPEAN PLATFORM. ARTICLE 1. THE BASEMENT TECTONICS

open access: yesИзвестия высших учебных заведений: Геология и разведка, 2018
General features of the basement tectonics of the East European platform (EEP) have been considered. The important role of the long-lived Paleoproterozoic tectonic zones has been noted.

A new look at old debates about the Corbières (NE-Pyrenees) geology: salt tectonics and gravity gliding

open access: yesBSGF - Earth Sciences Bulletin, 2023
In the Corbières area, a large-scale nappe has been identified at the beginning of the 20th century: the “Nappe des Corbières Orientales” (NCO) resting over a thick Triassic sole.

South Atlantic continental margins of Africa: a comparison of the tectonic vs climate interplay on the evolution of equatorial west Africa and SW Africa margins

open access: yes, 2005
The comparative review of 2 representative segments of Africa continental margin: the equatorial western Africa and the SW Africa margins, helps in analysing the main controlling factors on their development.

Detrital-zircon geochronology and provenance of the Ocloyic synorogenic clastic wedge, and Ordovician accretion of the Argentine Precordillera terrane [PDF]

open access: yes, 2015
The Precordillera terrane in northwestern Argentina is interpreted to be anexotic (Laurentian) continental fragment that was accreted to western Gondwanaduring the Ordovician. One prominent manifestation of the subductionand collision process is a Middle?

North America’s Midcontinent Rift: When rift met LIP [PDF]

open access: yesGeosphere, 2015
Rifts are segmented linear depressions that are filled with sedimentary and igneous rocks; they form by extension and often evolve into plate boundaries. Flood basalts, a class of large igneous provinces (LIPs), are broad regions of extensive volcanism formed by sublithospheric processes.

Rates of erosion and landscape change along the Blue Ridge escarpment, southern Appalachian Mountains, estimated from in situ cosmogenic 10Be [PDF]

open access: yes, 2016
The Blue Ridge escarpment, located within the southern Appalachian Mountains of Virginia and North Carolina, forms a distinct, steep boundary between the lower-elevation Piedmont and higher-elevation Blue Ridge physiographic provinces.

Local Strain Reorientation Explains Deformation of Rift-oblique Tectonic Lineaments Along the Main Ethiopian Rift

open access: yesTektonika
 The interaction between the NE-SW striking Main Ethiopian Rift (MER) and the E-W oriented Yerer-Tullu Wellel Volcano-tectonic lineament (YTVL) represents one of the least understood tectonic problems in the East African Rift System.

Evidence for Basement Reactivation during the Opening of the Labrador Sea from the Makkovik Province, Labrador, Canada: Insights from Field Data and Numerical Models

open access: yesGeosciences, 2018
The onshore exposures adjacent to modern, offshore passive continental margins may preserve evidence of deformation from the pre-, syn-, and post-rift phases of continental breakup that allow us to investigate the processes associated with and ...

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 ...
