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
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
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
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
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
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
Díaz García, Florentino ; Sánchez Martínez, Sonia ; Castiñeiras García, Pedro ; Fuenlabrada Pérez, José Manuel ; Arenas Martín, Ricardo | Elsevier Science B. V., Amsterdam | 2009The arc-derived upper units of the Órdenes Complex, NW Iberia, are emplaced above the Variscan suture and contain a low-grade metasedimentary uppermost section, with a maximum depositional age of 510–530 Ma, intruded by a number of mafic dykes. [...]texto impreso
Fuenlabrada Pérez, José Manuel ; Arenas Martín, Ricardo ; Sánchez Martínez, Sonia ; Díaz García, Florentino ; Castiñeiras García, Pedro | Elsevier Science B. V., Amsterdam | 2010The arc-derived upper terrane in the NW Iberia Variscan belt contains a 3000 m thick turbiditic formation at its structural top. Most of the sandstones are feldspathic greywackes with a framework of quartz and weakly altered plagioclase. Rock fr[...]texto impreso
Castiñeiras García, Pedro ; Díaz García, Florentino ; Gómez Barreiro, Juan | Elsevier Science B.V., Amsterdam | 2010The A Silva granodiorite is a plutonic body intruded into the metasediments of the upper unit of the Órdenes Complex (Variscan belt, NW Spain). These metasediments represent the middle section of a magmatic arc located in northern Gondwana. The [...]texto impreso
Martínez Catalán, José R. ; Arenas Martín, Ricardo ; Abati Gómez, Jacobo ; Sánchez Martínez, Sonia ; Díaz García, Florentino ; Fernández Suárez, Javier ; González Cuadra, Pablo ; Castiñeiras García, Pedro ; Gómez Barreiro, Juan ; Díez Montes, Alejandro ; González Clavijo, Emilio ; Rubio Pascual, Francisco J. ; Andonaegui Moreno, Pilar ; Jeffries, Teresa E. ; Alcock, James E. ; Díez Fernández, Rubén ; López Carmona, Alicia | Elsevier Masson, France | 2009Ophiolites of different Paleozoic ages occur in North-West (NW) Iberia in a rootless suture representing the remnants of the Rheic Ocean. Associated allochthonous terranes in the hanging- and foot-walls of the suture derive from the former margi[...]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
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
