Cretaceous—Quaternary tectonic evolution of the Tatra Mts (Western Carpathians): constraints from structural, sedimentary, geomorphological, and fission track data

open access: yesGeologica Carpathica, 2014
The Tatra Mts area, located in the northernmost part of Central Western Carpathians on the border between Slovakia and Poland, underwent a complex Alpine tectonic evolution.

Variscan and Alpine structure of the hills of Barcelona: geology in an urban area [PDF]

open access: yes, 2017
Line 9 of the underground railway is currently being constructed in Barcelona. This undertaking necessitates tunnelling through a number of hills that are mainly made up of Paleozoic rocks, which exhibit a complex structure due to the superposition of ...

Three-Dimensional Architecture of Foreland Basins from Seismic Noise Recording: Tectonic Implications for the Western End of the Guadalquivir Basin

open access: yesGeosciences
The Variscan and Mesozoic basement are covered by Neogene and Quaternary sediments belonging to the Guadalquivir foreland Basin (southern Spain). This study explores the subsurface of the northern margin of its westernmost sector using the HVSR method ...

Precambrian protoliths and Early Paleozoic magmatism in the French Massif Central: U–Pb data and the North Gondwana connection in the west European Variscan belt [PDF]

open access: yes, 2010
International audienceU–Pb geochronological data were collected on zircon by LA-MC-ICP-MS on orthogneiss and paragneiss from the Limousin area in the French Massif Central (FMC), in order to investigate the connection between the west European Variscan ...

Reconstructing a Super-Eruption From the Upper Ordovician Period in the Eastern Pyrenees, Spain [PDF]

open access: yesLithosphere
The Pyrenean basement rocks, NE of the Iberian Peninsula, southwestern Europe, include evidence of several pre-Variscan magmatic episodes which indicate the complex geodynamic history of this segment of the northern Gondwana margin from late ...

The role of the Kupferschiefer in the formation of hydrothermal base metal mineralization in the Spessart ore district, Germany: insight from detailed sulfur isotope studies [PDF]

open access: yes, 2018
The Spessart district (SW Germany), located at the southwestern margin of the Permian Kupferschiefer basin in Central Europe, hosts abundant stratabound and structurally controlled base metal mineralization.

Origin and emplacement of syn-orogenic Variscan granitoids in Iberia the Beiras massif [PDF]

open access: yes, 2005
The Beiras batholith consists of four main Variscan granitoid suites intruded into metasediments of Proterozoic-Cambrian and Palaeozoic age in Central Northern Portugal: a) the early, syn-D3 granodiorite-monzogranite suite (314-311 Ma); b) the highly ...

Structure and petrography of the Valle Mosso pluton, Sesia Magmatic System, Southern Alps

open access: yesJournal of Maps, 2017
The Valle Mosso pluton (VMP) is a Permian granitic body intruded at intermediate to upper crustal levels in the rocks of the pre-Alpine basement of the Ivrea-Verbano Zone and Serie dei Laghi shortly after the end of Variscan orogeny.

Tectonic evolution of the Plymouth Bay Basin [PDF]

open access: yes, 2013
A synthesis of offshore seismic data in the Plymouth Bay and Western Approaches, and onshore basement structures and mineralisation history has allowed new constraints to be placed on the structural evolution of the late Carboniferous- Triassic Plymouth ...

U‒Pb ages and Hf isotopic composition of zircons in Austrian last glacial loess: constraints on heavy mineral sources and sediment transport pathways [PDF]

open access: yes, 2015
Loess sediments in Austria deposited ca. 30‒20 ka ago yield different zircon age signatures for samples collected around Krems (SE Bohemian Massif; samples K23 and S1) and Wels (half-way between the Bohemian Massif and the Eastern Alps; sample A16 ...
