Linnemann, Ulf ; Pieren Pidal, Agustín Pedro ; Hofmann, Mandy ; Drost, Kerstin ; Quesada, Cecilio ; Gerdes, Axel ; Marko, Linda ; Gärtner, Andreas ; Zieger, Johannes ; Ulrich, Jens | Springer | 2018-04In the Cadomian orogen of the NE Bohemian Massif and of SW Iberia, a post-Gaskiers glacial event dated at c. 565 Ma has been detected. Such Ediacaran-aged glaciomarine deposits occur in the Weesenstein and Clanzschwitz groups of the Saxo-Thuring[...]texto impreso

Arenas Martín, Ricardo ; Sánchez Martínez, Sonia ; Díez Fernández, Rubén ; Gerdes, Axel ; Abati, Jacobo ; Fernández Suárez, Javier ; Andonaegui Moreno, Pilar ; González Cuadra, Pablo ; López Carmona, Alicia ; Albert Roper, Richard ; Fuenlabrada Pérez, José Manuel ; Rubio Pascual, Francisco J. | Elsevier | 2016-10NW Iberia includes a rather complete section of a Variscan suture, where different terranes with continental or oceanic affinities appear with clear structural relationships. Three groups of terranes, namely Upper, Ophiolitic and Basal units and[...]texto impreso
Abati Gómez, Jacobo ; Arenas Martín, Ricardo ; Díez Fernández, Rubén ; Albert, Richard ; Gerdes, Axel | Elsevier | 2018-12-01UPb and LuHf isotope ratios measured in zircon crystals from magmatic and metamorphic rocks provide crucial information to understand the origin and tectonothermal evolution of allochthonous terranes, and can contribute to paleogeographic recons[...]texto impreso

Abati Gómez, Jacobo ; Aghzer, Abdel Mouhsine ; Gerdes, Axel ; Ennih, Nasser | Elsevier Science B.V., Amsterdam | 2012The Lu-Hf isotopic composition of detrital zircons has been used to investigate the crustal evolution of the northern part of the West African Craton (WAC). The zircons were separated from six samples of siliciclastic sedimentary rocks from the [...]texto impreso
Abati Gómez, Jacobo ; Gerdes, Axel ; Fernández Suárez, Javier ; Arenas Martín, Ricardo ; Whitehouse, Martín J. ; Díez Fernández, Rubén | Société géologique de France | 2010In situ uranium-lead dating (LA-SF-ICPMS and SIMS) and Lu-Hf isotope analyses (LA-MC-ICP-MS) of zircon from eclogite facies rocks from the basal units of the Variscan Belt in Galicia constrain their magmatic and metamorphic evolution and give so[...]texto impreso
Albert Roper, Richard ; Arenas Martín, Ricardo ; Gerdes, Axel ; Sánchez Martínez, Sonia ; Marko, Linda | Sociedad Geológica de España. | 2016The Variscan Upper Allochthon is a continental-affinity terrane that recorded a Cambrian–Ediacaran magmatic arc generation, a subsequent transition to a passive margin, and a collision-related high-P metamorphism during the Devonian–Carboniferou[...]texto impreso
Albert Roper, Richard ; Arenas Martín, Ricardo ; Gerdes, Axel ; Sánchez Martínez, S. ; Marko, Linda | Wiley | 2015-12The Variscan Upper Allochthon is a continental-affinity terrane that recorded a Cambrian–Ediacaran magmatic arc generation, a subsequent transition to a passive margin, and a collision-related high-P metamorphism during the Devonian–Carboniferou[...]texto impreso
Albert, R. ; Arenas Martín, Ricardo ; Gerdes, Axel ; Sánchez Martínez, Sonia ; Fernández-Suárez, J. ; Fuenlabrada Pérez, José Manuel | Elsevier | 2015-12his study focuses on the provenance of the uppermost unit of the Upper Allochthon of the Variscan belt with combined U–Pb and Lu–Hf zircon (LA-ICPMS) and Sm–Nd whole-rock analyses. This unit is represented in the Cabo Ortegal Complex (NW Iberia)[...]texto impreso
Albert Roper, Richard ; Arenas Martín, Ricardo ; Sánchez Martínez, Sonia ; Gerdes, Axel | Universidad Complutense de Madrid | 2012The tectonothermal evolution of the eclogite facies gneisses of the Cabo Ortegal Complex has been investigated using new field and petrologic studies. This gneissic unit is included in the high-pressure and high-temperature (HP-HT) upper units o[...]texto impreso
Andonaegui Moreno, Pilar ; Arenas Martín, Ricardo ; Albert Roper, Richard ; Sánchez Martínez, Sonia ; Díez Fernández, Rubén ; Gerdes, Axel | Elsevier | 2016-06The upper allochthonous units of NW Iberian Massif contain an extensive Cambrian magmatism (c. 500 Ma), covering felsic to mafic compositions. The magmatic activity generated large massifs of granitoids and gabbros, with calc-alkaline and tholei[...]texto impreso
Arenas Martín, Ricardo ; Díez Fernández, Rubén ; Sánchez Martínez, Sonia ; Gerdes, Axel ; Fernández Suárez, Javier ; Albert, R. ; Fuenlabrada Pérez, José Manuel | Sociedad Geológica de España. | 2016The Variscan suture exposed in NW Iberia contains two allochthonous terranes with Gondwanan provenance (upper and basal units), separated by ophiolites with protolith ages at c. 395 Ma. The tectonothermal evolution of the continental terranes re[...]texto impreso
Arenas Martín, Ricardo ; Díez Fernández, Rubén ; Sánchez Martínez, Sonia ; Gerdes, Axel ; Fernández Suárez, Javier ; Albert Roper, Richard | Elsevier Science B. V., Amsterdam | 2014The Variscan suture exposed in NW Iberia contains a stack of terranes including two allochthonous units with continental affinity and Gondwanan provenance (Upper and Basal Units), separated by an ophiolite belt where the most common units show p[...]
