TL;DR: Based on the magmatic activity, filling sequence of basins, tectonic framework and subsidence analysis, the evolution of this area can be divided into three main developmental phases as mentioned in this paper.

TL;DR: In this paper, a revised kinematic model for the motions of Africa and Iberia relative to Europe since the Middle Jurassic is presented in order to provide boundary conditions for Alpine-Mediterranean reconstructions.

TL;DR: In this paper, a reconstruction of the tectonic evolution of the northern African margin in Tunisia since the Late Permian combining paleostress, stratigraphic and sedimentary approaches allows the characterization of several major periods corresponding to consistent stress patterns.

TL;DR: In this article, a revised tectonic model for SE Asia is proposed, which is based on the assumption that the main strike-slip faults (Mae Ping, Three Pagodas, Ranong and Klong Marui) cross Sundaland to the NW Borneo margin to facilitate continental extrusion.

TL;DR: In this article, the authors measured He diffusion characteristics in zircons from a range of quickly and slowly cooled samples, and the age-paleodepth relationships for samples from 15 to 18 km thick crustal section of the Gold Butte block, Nevada.

TL;DR: In this paper, the North American Cordillera provides a modern analogue for the evolution of Avalonia and other peri-Gondwanan terranes during the late Precambrian.

TL;DR: In this article, a 10m-thick lower-middle Miocene marine sedimentary sequence from southwestern Sardinia has been used to estimate the age of the Liguro-Provencal Basin.

TL;DR: In this paper, a numerical thermochemical convection model was used to simulate the subduction of an oceanic lithosphere that contains an 18 km-thick oceanic crustal plateau of 18-km thickness.

TL;DR: In this paper, a general model for true polar wander (TPW) in the context of supercontinents and simple modes of mantle convection is presented, in which an axis of mantle upwelling is established that is complementary to the downwelling girdle of subduction zones encircling the old supercontinent.

TL;DR: In this article, a 3D reassessment of the relationship between the principal crustal blocks abutting Baltica along the Trans-European Suture Zone (TESZ) is presented.

TL;DR: In this article, a seismic refraction/wide-angle reflection experiment was undertaken in the Levant Basin, eastern Mediterranean, using 16 ocean bottom seismometers deployed along the profiles with an air-gun array and explosive charges as energy sources.

TL;DR: In this article, integrated studies and revisions of sedimentary basins and associated magmatism in Peru and Bolivia (8-22°S) show that this part of western Gondwana underwent rifting during the Late Permian-Middle Jurassic interval.

TL;DR: In this paper, the authors determined magnetic lineation patterns as well as spreading rates deduced from the identification of magnetic lineations in the Huatung basin and the Taiwan Sea.

TL;DR: In this paper, the authors proposed that the Merida Andes structuration is related to a NW-directed, gently dipping, incipient type-A subduction, where chain growth and evolution are similar to those of a sedimentary accretionary wedge (i.e., Barbados), but at crustal scale and with ongoing strain partitioning.

TL;DR: This paper showed that magnetic lineation in deformed rocks is not the result of either bedding and cleavage intersection or they parallel the tectonic extension direction in high strain zones.

TL;DR: The project ISSA 2000 (Integrated Seismological experiment in the Southern Andes) consists of a temporary seismological network and a seismic refraction profile as mentioned in this paper, which consists of 62 seismological stations deployed at ∼38°S. Three hundred thirty-three local seismic events were observed in a 3-month period.

TL;DR: The origin of the deformation in the western and central Saharan Atlas (Algeria) is investigated in this article, where the authors show that the two periods of strong coupling between Europe and Africa (late Lutetian and Pleistocene) correspond to rapid uplifts of the Atlas system and important deformations, are not collision-related.

TL;DR: In this paper, the authors examined the quality of the National Research Institute for Earth Science and Disaster Prevention (NIED) seismic moment tensor (MT) catalogue obtained using a regional broadband seismic network (FREESIA).

TL;DR: In this article, the authors identify short-lived and long-lived plumes with a duration of magmatic activity of some 10-20 million years and 100-150 million years, respectively.

TL;DR: In this article, the geometry of the Altotiberina Fault (ATF) was reconstructed matching surface geology with seismic reflection profiles and borehole data, and the fault can be reactivated for low values of differential stress ( σ 1 − σ 3 T ∼10 MPa).

TL;DR: In this paper, a numerical modeling approach that simulates cracking and failure in rock and the associated seismicity is presented and a technique is described for quantifying the seismic source mechanisms of the modelled events.

TL;DR: In this article, the Cadomian tectonic elements were accreted to Gondwana during early Cadomians events (ca. 600 and 650 Ma), followed by further I-and S-type plutonism in an Andean-type continental margin setting between 570 and 520 Ma.

TL;DR: Apatite fission track and structural data outline the Late CretaceousCenozoic history of the southern Tan-Lu fault zone (TLFZ), one of Asia's major faults, the Triassic-Jurassic Dabie orogen, Earth's largest track of ultrahigh-pressure rock exposure, and its foreland, the Yangtze foreland fold-thrust belt as discussed by the authors.

TL;DR: The Cadomian basement and the Cambro-Ordovician overstep sequence in Saxo-Thuringia are characterized by clastic sedimentation from the Late Neoproterozoic to the Ordovician.

TL;DR: In this article, a semiquantitative reconstruction of the upper plate of the Eastern Alps is presented, based on displacement data of major faults that dissect the Austroalpine wedges.

TL;DR: In this paper, two east-west structural transects were mapped at Puyuhuapi and Aysen, immediately north of the Nazca-South America-Antarctica triple junction.

TL;DR: In this paper, a transient thermal and isostatic response to these changes is modelled, with the subsiding depocentre and eroding sediment source coupled by flow in the lower continental crust, and a value of ∼6×1019 Pa s is indicated, suggesting a viscosity at the Moho no greater than ∼1018 Pa s.

TL;DR: The most cited arguments for this Laurentia/Precordillera relationship are discussed, emphasising paleontological considerations in this paper, and it is shown that these arguments do not exclude a close original vicinity of the Precordilleras terrane to Gondwana.

TL;DR: The Tepla-Barrandian unit (TBU) of the Bohemian Massif shared a common geological history throughout the Neoproterozoic and Cambrian with the Avalonian-Cadomian terranes as mentioned in this paper.

TL;DR: The Elbe Fault System (EFS) is a WNWstriking zone extending from the southeastern North Sea to southwestern Poland along the present southern margin of the North German Basin and the northern margin of Sudetes Mountains.
