Complex examination of the Upper Paleozoic siliciclastic rocks from southern Transdanubia, SW Hungary—Mineralogical, petrographic, and geochemical study [PDF]

open access: yes, 2007
A vertical section of Upper Paleozoic sandstones from southern Transdanubia (Mecsek-Villány area, Tisza mega-unit, Hungary) has been analyzed for major and trace elements, including rare earth elements (REEs).

Radial anisotropy and S-wave velocity depict the internal to external zone transition within the Variscan orogen (NW Iberia) [PDF]

open access: yesSolid Earth, 2022
The cross-correlation of ambient noise records registered by seismic networks has proven to be a valuable tool to obtain new insights into the crustal structure at different scales.

Tertiary-Quaternary intra-plate magmatism in Europe and its relationship to mantle dynamics [PDF]

open access: yes, 2006
Anorogenic intra-plate magmatism was widespread in Europe from early Tertiary to Recent times, extending west to east from Spain to Bulgaria, and south to north from Sicily to northern Germany. Magmatism is spatially and temporally associated with Alpine-

A Clockwise P-T Path from the Variscan Basement of the Tisza Unit, Pannonian Basin, Hungary

open access: yesGeologia Croatica, 2010
The polymetamorphic basement of the Tisza Unit forms a detachedfragment of the Variscan European foreland of the Neotethyanrealm. A clockwise evolution path of a gneiss-amphibolite complexof the Tisza Unit was reconstructed, investigating the ...

Thermal evolution of a Variscan syn-orogenic intracontinental basin (Servoz basin, Western Alps): RSCM geothermometry and geochronology

open access: yesSwiss Journal of Geosciences, 2022
The Variscan basement of the Aiguilles-Rouges massif (Western Alps) exposes the Servoz syncline which consists of a metavolcano-sedimentary sequence composed of (i) a volcanic unit of unknown age and origin, (ii) Early Carboniferous sedimentary series ...

Constraining the Timing of Evolution of Shear Zones in Two Collisional Orogens: Fusing Structural Geology and Geochronology

open access: yesGeosciences, 2022
In recent decades, constraining the timing of shear activity has been one of the main topics of research about the tectono-metamorphic evolution of orogenic belts.

The concealed Caledonide basement of eastern England and the southern North Sea : a review [PDF]

open access: yes, 1995
Field mapping, analysis of borehole core and studies of geophysical potential field and seismic data can be used to demonstrate the existence of a number of distinct crustal blocks within Eastern Avalonia beneath eastern England and the southern North ...

The Schwarzhorn Amphibolite (Eastern Rätikon, Austria): an Early Cambrian intrusion in the Lower Austroalpine basement

open access: yesGeologica Carpathica, 2016
The Alpine nappe stack in the Penninic-Austroalpine boundary zone in the Rätikon (Austria) contains a 4×1 km tectonic sliver of meta-diorite, known as the Schwarzhorn Amphibolite.

Evidence for surface uplift of the Atlas Mountains and the surrounding peripheral plateaux: Combining apatite fission-track results and geomorphic indicators in the Western Moroccan Meseta (coastal Variscan Paleozoic basement) [PDF]

open access: yes, 2010
This work represents an initial attempt to link the evolution of the topography in relation to the general tectonic framework of western Morocco. For this purpose, in a section of the Western Moroccan Meseta different tools are combined in order to ...

Geochemistry of the Görcsöny Ridge amphibolites (Tisza Unit, SW Hungary) and its geodynamic consequences

open access: yesGeologia Croatica, 2014
The Görcsöny Ridge is part of the complicated Variscan metamorphic basement of the SW Tisza plate. It was penetrated by several wells, one of which (Baksa-2) explored 1200 m borecore available for petrological examination.
