Gravitational orogenic collapse vs plate-boundary stresses: a numerical modelling approach to the Permo-Carboniferous evolution of Central Europe
TL;DR: In this paper, a two-dimensional thermo-mechanical finite element model is used to study the Permo-Carboniferous evolution of Central Europe along a lithosphere-scale transect from the Variscan Internides to the undeformed foreland.

Abstract: A two-dimensional thermo-mechanical finite element model is used to study the Permo-Carboniferous evolution of Central Europe along a lithosphere-scale transect from the Variscan Internides to the undeformed foreland The study concentrates on a quantitative evaluation of the processes controlling late-orogenic extension and destruction of the Variscides, particularly the gravitational instability of thickened crust Modelling results suggest that gravitational forces along cannot reproduce the observed timing and amount of Permo-Carboniferous crustal thinning Tensile plate-boundary forces are required in addition to gravitation to restore a crustal thickness of approximately 30 km in the Variscan Internides Stresses as little as 10 MPa result in up to 28% extension and a good fit between observed data and model predictions It is concluded that the Stephanian to Rotliegend evolution in the vicinity of the modelled traverse resulted not from gravitational forces inherited from Variscan crustal thickening, but was related to a change in orientation of the plate-boundary stresses at the end of the Westphalian

Phases of Enhanced Exhumation During the Cretaceous and Cenozoic Orogenies in the Eastern European Alps: New Insights From Thermochronological Data and Thermokinematic Modeling
A. Wölfler,Reinhard Wolff,Andrea Hampel,Ralf Hetzel,István Dunkl +4 more
TL;DR: Thermochronological data and thermokinematic modeling reveal distinct exhumation phases in the Eastern European Alps during Cretaceous and Cenozoic orogenies, driven by extension, collision, and escape tectonics, with varying exhumation rates and timing across different structural levels and units.
Evolution and structure of the Upper Rhine Graben: insights from three-dimensional thermomechanical modelling
Michael Schwarz,Andreas Henk +1 more
TL;DR: In this paper, the authors used 3D finite element techniques to simulate extension and lateral translation on a lithospheric scale in the Tertiary Upper Rhine Graben and found that the shape of the border faults, their frictional coefficients, and sedimentary loads have profound effects on the rate of ductile flow across the graben.
Zircon age of vaugnerite intrusives from the Central and Southern Vosges crystalline massif (E France): contribution to the geodynamics of the European Variscan belt
TL;DR: In this article, the authors focused on vaugnerites, which consist of mafic ultra-potassic magmatic rocks, intrusive into the granite-gneiss sequences of the Variscan Vosges crystalline massif.
The tectonosedimentary evolution of the northern margin of the Carboniferous foreland basin of NE Germany
TL;DR: In this article, the geology and evolution of the northern margin of the Carboniferous foreland basin in NE Germany was examined in terms of depositional environments, petrographic and geochemical data.
Origin and significance of the Permian high-K calc-alkaline magmatism in the central-eastern Southern Alps, Italy
A. Rottura,Giuseppe Maria Bargossi,Alfredo Caggianelli,A. Del Moro,Dario Visonà,Claudio Antonio Tranne +5 more
TL;DR: The Atesina Volcanic District, the Monte Luco volcanics, and the Cima d'Asta, Bressanone-Chiusa, Ivigna, Monte Croce and Monte Sabion intrusions, in the central-eastern Southern Alps, form a wide calc-alkaline association of Permian age (ca. 280-260 Ma).

Friction of Rocks
TL;DR: This paper showed that at low normal stress the shear stress required to slide one rock over another varies widely between experiments and at high normal stress that effect is diminished and the friction is nearly independent of rock type.

Fault rocks and fault mechanisms
TL;DR: In this paper, physical factors likely to affect the genesis of the various fault rocks are examined in relation to the energy budget of fault zones, the main velocity modes of faulting and the type of fault, whether thrust, wrench, or normal.

Strength of the lithosphere: Constraints imposed by laboratory experiments
TL;DR: The concept of strength envelopes, developed in the 1970s, allowed quantitative predictions of the strength of the lithosphere based on experimentally determined constitutive equations as mentioned in this paper, which can be applied to understand a broad range of topical problems in regional and global tectonics both on the Earth and on other planetary bodies.

Extensional collapse of orogens
TL;DR: The extensional collapse of orogens offers a partial explanation for why oceans cyclically close and reopen in roughly the same places, preservation of very high pressure metamorphic rocks, for the return of orogenic large crustal thicknesses to normal without very much erosional denudation.
