Ductile Shearing and Focussed Rejuvenation: Records of High-P (eo-)Alpine Metamorphism in the Variscan Lower Crust (Serre Massif, Calabria—Southern Italy)

Geosciences, 2022
In the present study, we unveil the real significance of mylonitic reworking of the polymetamorphic crystalline basement in the Serre Massif of Calabria (Southern Italy).

The Variscan Belt of Western Europe 1

, 2023
International audienceThis chapter deals with the metamorphic and structural aspects of the principal events responsible for the early architecture of the French Variscan belt, before the tectono-metamorphic events coeval with its late- and post-orogenic

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

Geologia 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 ...

Cambrian magmatism, Variscan high-grade metamorphism and imposed greenschist facies shearing in the Central Sredna Gora basement units (Bulgaria)

Geologica Carpathica, 2015
Gneisses from the deep structural levels of the European Variscan Belt are well exposed in the Central Sredna Gora in Bulgaria. In general, migmatites predominate, but unmigmatized domains (or domains with incipient migmatization) are also documented in ...

Sulphur isotope geochemistry of black shale-hosted antimony mineralization, Arnsberg, northern Rhenish Massif, Germany [PDF]

, 2003
Vein-type and bedding-concordant mesothermal (180–410 °C) stibnite–sulphosalt mineralization at Arnsberg, NE Rhenish Massif, Germany, is hosted by Carboniferous pyrite-rich black shales and siliceous limestones.

⁴⁰Ar ∕ ³⁹Ar age constraints on the formation of fluid-rich quartz veins from the NW Rhenohercynian zone (Rursee area, Germany) [PDF]

Geochronology
A substantial part of the subsurface geology in northwestern and central Europe is defined by the late Palaeozoic Variscan Orogeny (∼ 350 Ma). Our focus is mainly on veining in anchimetamorphic sedimentary rocks affected by this orogeny.

Magnetic mineralogy of Variscan granites from northern Portugal: an approach to their petrogenesis and metallogenic potential

Geologica Acta, 2020
Northern Portugal is characterized by the occurrence of numerous W hydrothermal deposits spatially associated with granites. The primary goal of this work is to establish a relationship between the magnetic behavior of the granites and the redox ...

Deglaciation of the Burren glacio‐karst, western Ireland, during Termination 1: Implications for North Atlantic climate and karstification

Journal of Quaternary Science, EarlyView.
Abstract The Burren uplands in western Ireland form one of the most extensive and best‐preserved examples of glacio‐karst in Europe. Subsumed by the Irish ice sheet during the Late Pleistocene, granite erratic boulders and in situ silica veins in the limestone bedrock provide a rare opportunity to reconstruct the timing and rate of deglaciation ...

From Inventories to Insights: Environmental Gradients Structuring Macro‐Moths Assemblages Recorded in Nature Reserves [PDF]

Ecol Evol
The article analyses macro‐moth (Lepidoptera) inventory data from 292 nature reserves across the Czech Republic, comprising 941 species. It examines how reserve characteristics, geographic position and altitude influence species richness, community composition and their associations with species traits.
