Alcock, James E ; Martínez Catalán, José R. ; Rubio Pascual, Francisco J. ; Díez Montes, Alejandro ; Díez Fernández, Rubén ; Gómez Barreiro, Juan ; Arenas Martín, Ricardo ; Dias da Silva, Ícaro ; González Clavijo, Emilio | Elsevier | 2015-08-30A model for the P–T–t evolution of NW and Central Iberia is presented to better understand its metamorphic evolution from initial Barrovian stage through HT–LP conditions. The model is constrained by the well-known succession of structural event[...]texto impreso
Gómez Barreiro, Juan ; Wijbrans, Jan R. ; Castiñeiras García, Pedro ; Martínez Catalán, José R. ; Arenas Martín, Ricardo ; Díaz García, Florentino ; Abati Gómez, Jacobo | Geological Society of London. | 2006The tectonothermal evolution of a polyorogenic terrane in the Variscan belt of NW Spain has been constrained by 40Ar/39Ar laserprobe incremental heating experiments on mylonitic fabrics developed in major structures. Transitional levels between [...]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
Las anfibolitas granatíferas que afloran dentro de la formación de Micaesquistos de La Albariza - Bembezar (Sierra Albarrana), en condiciones propias de la zona de la estaurolita (+ distena), contienen una paragénesis principal (pico térmico) co[...]texto impreso
Abati Gómez, Jacobo ; Arenas Martín, Ricardo ; Martínez Catalán, José Ramón ; Díaz García, Florentino | Oxford University Press | 2003The study of mafic and aluminous granulites from the Monte Castelo Gabbro (Órdenes Complex, NW Spain) reveals an anticlockwise P–T path that we interpret as related to the tectonothermal activity in a magmatic arc, probably an island arc. The P–[...]texto impreso
Aportación geoquímica al conocimiento de los materiales volcánicos del Cámbrico medio de Zafra-Feria
Sagredo Ruiz, Juana ; Peinado Moreno, Mercedes ; Brändle, J.L. ; Arenas Martín, Ricardo ; Ancochea Soto, Eumenio | Universidade de Aveiro, Departamento de Geociências | 1988Los materiales volcánicos intercalados en el Cámbrico medio de Ossa Morena, bien expuestos en la alineación Zafra-Feria constituyen una serie moderadamente alcalina formada por basaltos plagioclásicos de ambiente submarino somero, traquitas y ri[...]texto impreso
Sánchez Martínez, Sonia ; Arenas Martín, Ricardo ; Díaz García, Florentino ; Martínez Catalán, José Ramón ; Gómez Barreiro, Juan ; Pearce, Julian A. | Geological Society of America | 2007The Careón ophiolite (Galicia, NW Iberian Massif) shows lithological and geochemical features suggestive of an origin in a suprasubduction zone setting. As with other Devonian ophiolites in the European Variscan belt, it was generated within a c[...]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

Fernández Suárez, Javier ; Díaz García, Florentino ; Jeffries, Teresa E. ; Arenas Martín, Ricardo ; Abati Gómez, Jacobo | Blackwell Publishing Ltd | 2003Insight into the origin and pre-orogenic palaeogeographical links of terranes involved in the assembly of collisional mountain belts is fundamental to the understanding of orogenic processes. Here we address the provenance and possible tectonic [...]texto impreso
Rojo-Pérez, Esther ; Arenas Martín, Ricardo ; Fuenlabrada Pérez, José Manuel ; Sánchez Martínez, Sonia ; Martín Parra, Luis Miguel ; Matas, Jerónimo ; Pieren Pidal, Agustín Pedro ; Díez Fernández, Rubén | Elsevier | 2019-05In the Iberian Massif, westernmost sector of the Variscan Orogen, the nature of the boundary between the Central Iberian Zone and the Ossa Morena Complex has been largely discussed. Peri-Gondwanan Ediacaran series similar in age (c. 565?Ma) but [...]texto impreso
La correlación de tres cinturones de alta-P y baja a media-T del NO y SO de Iberia basada en la edad de dicho metamorfismo, su litostratigrafía y tectonostratigrafía regional, y apoyada por la geometría de estructuras regionales mayores, permite[...]texto impreso
A la suite de sa deformation en regime compressif sous des conditions métamorphiques barroviennes culminant dans le facies amphibolite superieur, le massif des Rehamna est affecté par une tectonique extensive. Celle-ci s’est manifestee dans troi[...]texto impreso
Dallmeyer, R. David ; Martínez Catalán, José Ramón ; Arenas Martín, Ricardo ; Gil Ibarguchi, José Ignacio ; Gutiérrez Alonso, Gabriel ; Farias Arquer, Pedro ; Bastida Ibáñez, Fernando ; Aller, Jesús(1956-) | Elsevier, B.V. | 1997Multigrain concentrates of hornblende and muscovite together with whole-rock slate/phyllite samples have been dated (27 analyses) using 40Ar/39Ar incremental-release methods along a systematic traverse across the various lithotectonic structural[...]texto impreso
Abati Gómez, Jacobo ; Dunning, Gregory R. ; Arenas Martín, Ricardo ; Díaz García, Florentino ; González Cuadra, Pablo ; Martínez Catalán, José Ramón ; Andonaegui Moreno, Pilar | Elsevier Science B.V., Amsterdam | 1999New U–Pb data (zircon, monazite and rutile) obtained from rocks of the uppermost allochthon in the Variscan belt of NW Spain indicate that the hangingwall to the suture includes an allochthonous unit with a pre-Variscan tectonothermal evolution.[...]
