Diachronous Variscan tectonothermal activity in the NW Iberian Massif: Evidence from 40Ar/39Ar dating of regional fabrics

TL;DR: In this article, multigrain concentrates of hornblende and muscovite together with whole-rock slate/phyllite samples have been dated using 40Ar/39Ar incremental-release methods along a systematic traverse across the various lithotectonic structural elements which comprise northwestern sectors of the Variscan Iberian Massif.
Journal ArticleDOI

Early Ordovician orogenic event in Galicia (NW Spain): evidence from U–Pb ages in the uppermost unit of the Ordenes Complex

TL;DR: In this article, the uppermost allochthon in the Variscan belt of NW Spain has been studied and it is shown that the hangingwall to the suture includes a pre-Variscan tectonothermal unit.
Journal ArticleDOI

High‐pressure micro‐inclusions and development of an inverted metamorphic gradient in the Santiago Schists (Ordenes Complex, NW Iberian Massif, Spain): evidence of subduction and syncollisional decompression

TL;DR: The Santiago Schists are located in the Basal Unit of the Ordenes Complex, one of the allochthonous complexes outcropping in the inner part of the Hercynian Belt in the north-west of the Iberian Peninsula.
Journal ArticleDOI

U-Pb zircon and monazite geochronology of Variscan magmatism related to syn-convergence extension in Central Northern Portugal

TL;DR: In this article, the authors reported high precision U-Pb zircon and monazite ages for four plutons of the Viseu area: the syn-kinematic granitoids of Maceira (314±5 Ma), Casal Vasco (311±1 Ma), Junqueira (307.8±0.7 Ma), and Cota (306±9 Ma).
Journal ArticleDOI

Role of the Ollo de Sapo massive felsic volcanism of NW Iberia in the Early Ordovician dynamics of northern Gondwana

TL;DR: The Ollo de Sapo Fm. as mentioned in this paper is made up of two large superposed volcanic domes separated by a thin screen of contemporaneous metapelites and sandstones.
