Fernández Suárez, Javier ; Gutiérrez Alonso, Gabriel ; Cox, Richard ; Jenner, A. | Chicago, University of Chicago Press. | 2002Detrital zircons separated from the Ordovician Armorican quartzite in the foreland of the Variscan belt of Iberia were dated by laser ablation inductively coupled plasma mass spectrometry. The age groups found correspond to Proterozoic and Arche[...]texto impreso
Fernández Suárez, Javier ; Gutiérrez Alonso, Gabriel ; Jenner, G.A. ; Tubrett, M.N. | Geological Society of London. | 1999Detrital zircons from greywackes belonging to an Ordovician volcanosedimentary–igneous complex in NW Spain were dated using the laser ablation-inductively coupled plasma-mass spectrometry technique. U–Pb results indicate the existence of three P[...]texto impreso
Gutiérrez Alonso, Gabriel ; Collins, Alan S. ; FernándezSuárez, Javier ; Pastor Galán, Daniel ; González Clavijo, Emilio ; Jourdan, Fred ; Weil, Arlo B. ; Johnston, Stephen T. | Elsevier | 2015-03-07Abstract Orogenic curvature is a ubiquitous feature of mountain belts, and the plate tectonic and geodynamic setting responsible for the development of curved orogens is a subject of debate. In order to distinguish between different models of or[...]texto impreso
Gutiérrez Alonso, Gabriel ; Fernández Suárez, Javier ; Jeffries, Teresa E. ; Johnston, Stephen T. | American Geophysical Union | 2011U?Pb (zircon) crystallization ages of 52 late?Variscan granitoid intrusions from NW Iberia (19 from new data, 33 from previous studies) constrain the lithospheric evolution of this realm of the Variscan belt of Western Europe and allow assessmen[...]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
Fernández Suárez, Javier ; Gutiérrez Alonso, Gabriel ; Johnston, Stephen T. ; Jeffries, Teresa E. ; Pastor Galán, Daniel ; Jenner, G.A. ; Murphy, J. Brendam | Elsevier Science B.V., Amsterdam | 2011A suite of post-tectonic granitoids (mostly peraluminous, broadly I-type granodiorites and monzogranites) and mafic rocks from NWIberia with crystallization ages between ca. 309 and 290 Ma has been investigated for Sm–Nd isotopes and inherited z[...]texto impreso
Fernández Suárez, Javier ; Gutiérrez Alonso, Gabriel ; Jenner, G.A. ; Tubrett, M.N. | Elsevier Science B.V., Amsterdam | 2000U–Pb ages were obtained on single detrital zircon grains separated from six samples of Neoproterozoic and Lower Palaeozoic sedimentary and volcanosedimentary rocks from NW Iberia using the laser ablation microprobe-inductively coupled plasma mas[...]texto impreso
Gutiérrez Alonso, Gabriel ; Fernández Suárez, Javier ; Weil, Arlo B. | Sociedad Geológica de España. | 2004Late- to post-orogenic oroclinal bending in conjunction with thinning of the lithospheric mantle is potentially an important component of the waning stages of plate convergence in collisional orogenies. This paper addresses possible and hitherto[...]texto impreso
Brendan Murphy, J. ; Gutiérrez Alonso, Gabriel ; Fernández Suárez, Javier ; Braid, James A. | Elsevier | 2008Northwestern Iberia preserves one of the most complete Paleozoic sequences that document the origin and development of a passive margin along the southern (Gondwanan) flank of the Rheic Ocean. In addition to a well preserved sedimentary record, [...]texto impreso
Gutiérrez Alonso, Gabriel ; Murphy, J. Brendam ; Fernández Suárez, Javier ; Hamilton, M.A. | Elsevier | 2008Exposures of volcanic rocks (El Castillo) in the Central Iberian Zone near Salamanca, Spain, are representative of Paleozoic volcanic activity along the northern Gondwanan passive margin. Alkaline basalts and mafic volcaniclastic rocks of this s[...]texto impreso
Gutiérrez Alonso, Gabriel ; Fernández Suárez, Javier ; Weil, Arlo B. ; Murphy, J. Brendam ; Nance, R. Damian ; Corfu, Fernando ; Johnston, Stephen T. | Nature Publishing Group | 2008One of the most striking and rare occurrences in the Earth's history is the amalgamation of most of the continental lithosphere into one supercontinent. The most recent supercontinent, Pangaea, lasted from 320 to 200 million years ago. Here, we [...]texto impreso
Fernández Lozano, Javier ; Gutiérrez Alonso, Gabriel ; Willingshofer, Erns ; Sokoutis, Dimitrios ; De Vicente Muñoz, Gerardo ; Cloetingh, Sierd | Geological Society of America | 2019The present-day topography in Iberia is related to geodynamic processes dealing with lithospheric-scale deformation. However, little attention has been paid to the role of inherited crustal- or lithospheric-scale structures involved in the recen[...]texto impreso
Gutiérrez Alonso, Gabriel ; Fernández Suárez, Javier ; Pastor Galán, D. ; Johnston, S. T. ; Linnemann, U. ; Hofmann, M. ; Shaw, J. ; Colmenero, J. R. ; Hernández, P. | Geological Society of London. | 2015Seven samples of Siluro-Devonian sedimentary rocks from the Cantabrian and Central Iberian zones of the Iberian Variscan belt have been investigated for provenance and contain four main age populations in variable relative proportion: Ediacaran–[...]texto impreso
Fernández Lozano, Javier ; Gutiérrez Alonso, Gabriel ; Sokoutis, D. ; Willingshofer, Ernst ; De Vicente Muñoz, Gerardo ; Cloetingh, Sierd | Sociedad Geológica de España. | 2016La península ibérica constituye un laboratorio natural para el conocimiento de la deformación intraplaca alpina. Aunque la actual topografía es el resultado de los últimos eventos tectónicos ocurridos entre el Eoceno y el Mioceno inferior, la ev[...]texto impreso
Pastor Galán, Daniel ; Gutiérrez Alonso, Gabriel ; Fernández Suárez, Javier ; Brendan Murphy, J. ; Nieto, Fernando | Elsevier Science B.V., Amsterdam | 2013The Cantabrian Zone of NWIberia preserves a voluminous, almost continuous, sedimentary sequence that ranges in age from Ediacaran to Early Permian. Its tectonic setting is controversial and recent hypotheses include (i) passive margin deposition[...]
