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
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
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.[...]texto impreso
Díez Fernández, Rubén ; Martínez Catalán, José Ramón ; Gómez Barreiro, Juan ; Arenas Martín, Ricardo | Chicago, University of Chicago Press. | 2012Plate convergence analysis in collisional orogens is usually based on the study of major contractional structures and strike-slip shear zones. Here we show how the structural analysis of extensional structures may report the regional or far stre[...]texto impreso
Gómez Barreiro, Juan ; Martínez Catalán, José Ramón ; Prior, D. ; Wenk, H.-R. ; Vogel, S. ; Díaz García, Florentino ; Arenas Martín, Ricardo ; Sánchez Martínez, Sonia ; Lonardelli, I. | University of Chigaco Press | 2010A Middle Devonian suprasubduction zone ophiolite, the Careo´n Unit (northwest Spain), displays amphibolite-facies ductile deformation fabrics related to the onset of the Rheic Ocean closure. Two different fabrics, an early high-T foliation and a[...]texto impreso
The Mondoñedo nappe is a crystalline thrust sheet characterized by large recumbent folds, regional intermediate-pressure metamorphism, synkinematic intrusion of granitoids during nappe emplacement, and an extensional ductile shear zone developed[...]texto impreso
The Mondoñedo thrust sheet has been studied to investigate the complex dynamic relationships that may be involved in the development of low- and medium-P metamorphic domains. This unit underwent an initial medium-P event during the initial stage[...]texto impreso

Arenas Martín, Ricardo ; Abati Gómez, Jacobo ; Martínez Catalán, José Ramón ; Díaz García, Florentino ; Rubio Pascual, Francisco J. | Elsevier Science B.V., Amsterdam | 1997Eklogite lenses in the Agualada Unit (western Ordenes Complex, Spain) contain the peak mineral assemblage garnet (prograde rim: Alm = 48 mol%, Ptp = 30 mol%), omphacite (Jd max = 36 mol%), quartz, rutile and rare zoisite, which equilibrated at T[...]texto impreso
The Ordenes Complex, Galicia, NW Spain, preserves high-pressure, moderate-temperature metamorphism in continental margin rocks subducted during closure of the Rheic Ocean in the Variscan orogeny. The exposures extend across c90 km perpendicular [...]texto impreso
Díaz García, Florentino ; Martínez Catalán, José Ramón ; Arenas Martín, Ricardo ; González Cuadra, Pablo | Springer Science Business Media | 1999An important detachment is described in the allochthonous Ordenes Complex, in the NW Iberian Massif, and its meaning is related to the kinematics of contemporaneous convergent structures. The Corredoiras Detachment (CD) separates a hangingwall u[...]texto impreso
Díez Fernández, Rubén ; Martínez Catalán, José Ramón ; Arenas Martín, Ricardo ; Abati Gómez, Jacobo | European Geoscience Union | 2011A regional study starting from detailed geological mapping has been carried out in the Malpica?Tui Complex of Galicia in NW Spain. The complex is formed by two units representing pieces of the external edge of Gondwana, subducted and exhumed dur[...]texto impreso
Díaz García, Florentino ; Arenas Martín, Ricardo ; Martínez Catalán, José Ramón ; González del Tánago, José ; Dunning, Gregory R. | University of Chigaco Press | 1999Analysis of the Careoó Unit in the Ordenes Complex (northwest Iberian Massif) has supplied relevant data concerning the existence of a Paleozoic oceanic lithosphere, probably related to the Rheic realm, and the early subduction-related events th[...]texto impreso
Andonaegui Moreno, Pilar ; Castiñeiras García, Pedro ; González Cuadra, Pablo ; Arenas Martín, Ricardo ; Sánchez Martínez, Sonia ; Abati Gómez, Jacobo ; Díaz García, Florentino ; Martínez Catalán, José Ramón | Elsevier Science B.V., Amsterdam | 2012The Corredoiras orthogneiss belongs to the intermediate pressure upper units of the Órdenes Complex (Variscan belt, NW Spain), mainly composed by granodioritic orthogneisses, with small bodies of tonalitic orthogneisses, amphibole-rich orthognei[...]
