Magnetization related to late-Variscan extensional collapse in the Lugo Dome (NW Iberian Massif): a metamorphic petrology approach

open access: yes
The Eastern Galicia Magnetic Anomaly (EGMA) is one of the most distinctive and best studied magnetic anomalies in Iberia. It is located in NW Spain and overlaps the Variscan gneissic domes of Lugo and Sanabria.

Thermal studies on the lower Carboniferous basins of Khenifra and Qasbat-Tadla, Morocco: What do they teach us about the pre-Variscan stages in NW Africa?

open access: yes
Within the Variscan Belt of Morocco, the Central Massif preserves Early Carboniferous rift basins. The Lower Carboniferous Khenifra and Qasbat-Tadla basins are aborted rifts, developed just before the Variscan orogenesis in Morocco that occurred during ...

About a peri-Gondwanan-North African enlarged acceptance of the Caledonian Orogeny

open access: yes, 2011
The notion of “Caledonian Orogeny” is restricted by most authors to the Ordovician-Devonian thermotectonic events associated with the Laurentia-Baltica- Avalonia suturing.

Paleozoic evolution of pre-Variscan terranes: From Gondwana to the Variscan collision

open access: yes, 2005
The well-known Variscan basement areas of Europe contain relic terranes with a pre- Variscan evolution testifying to their peri-Gondwanan origin (e.g., relics of Neoproterozoic volcanic arcs, and subsequent stages of accretionary wedges, backarc ...

Outline of the Variscan basement of Sardinia [PDF]

open access: yes, 2009
In Sardinia a quasi-complete section of the southern branch of the Variscan orogenic belt crops out, characterized by non-metamorphosed to high-grade rocks, whose age ranges from Early Cambrian to Early Carboniferous, and that are involved in a complex ...

Cenozoic Reactivation of the Penacova-Régua-Verin and Manteigas-Vilariça-Bragança Fault Systems (Iberian Peninsula): Implication in Their Seismogenic Potential

open access: yesGeosciences
The Penacova-Régua-Verin (PRV) and the Manteigas-Vilariça-Bragança (MVB) are two of the longest faults of the Iberian Peninsula. These faults striking NNE–SSW, over lengths of >200 km, were developed during late-Variscan Orogeny and reactivated in ...

Geochronology and petrogenesis of late-Variscan plutonism (NW Portugal) : synthesis and inferences on crustal recycling and growth [PDF]

open access: yes, 2009
In NW Portugal large volumes of granitoids were emplaced during the post-collisional stage of the Variscan orogeny. This was the main period of successive granite generation, which exhibit different chemical and isotopic signatures.

The Ordovician Sardic and Sarrabese phases in the South European Variscan Belt: correlation between Sardinia, Eastern Pyrenees and Occitan Domain

open access: yes, 2022
Evidence of Ordovician tectonics is well preserved in the Variscan terrains now scattered in the circum-Mediterranean areas. It was in SW Sardinia (the External Zone of the Variscan basement) that was firstly detected the so-called Sardic Phase, a ...
