Les granitoides varisques de la Meseta iberique

Exhuming a cold case: The early granodiorites of the northwest Iberian Variscan belt—A Visean magmatic flare-up?

“…2). This feature has been classically interpreted as the result of their emplacement having occurred at deeper crustal levels than that of the younger granitoid groups (Capdevila et al, 1973;Bellido Mulas et al, 1987). Figure 2 is a simplified geological map of northwest Iberia showing the plutons dated in this study and the location of each sample.…”

“…A third suite of Variscan granitoids (the object of this study), putatively older than the syntectonic leucogranitoids, was postulated in the early works of Den Tex (1966), Capdevila (1969), and Capdevila et al (1973), based mainly on the presence of a tectonic foliation and a more mafic composition than that of the synextensional granitoids. They are commonly labeled Granodioritas precoces (early granodiorites), following De Pablo Maciá (1981) and González Lodeiro et al (1984), and were interpreted as being deeper seated intrusions than the POS.…”

“…The main objective of this study is to test the existence of an older (early Carboniferous) suite of Variscan intrusions in northwest Iberia that would broadly correspond to the G1 type of Capdevila et al (1973) or early granodiorites of De Pablo Maciá (1981). This early Carboniferous suite is widely represented in other areas of the WEVB (e.g., Schaltegger, 1997Schaltegger, , 2000Schulmann et al, 2002;Eichhorn et al, 2000;Cartannaz et al, 2007;Li et al, 2014;Mezger and Gerdes, 2016;Tabaud et al, 2015;Galán et al, 1997;Ledru et al, 2001;Rossi et al, 2009;Kubínová et al, 2017;Laurent et al, 2017;Žák et al, 2017), including the Ossa Morena zone of southwest Iberia (e.g., Dallmeyer et al, 1995;Ordóñez Casado, 1998;Montero et al, 2000;Ordóñez Casado et al, 2008;Romeo et al, 2006;Jesus et al, 2007;Pin et al, 2008;Pereira et al, 2009Pereira et al, , 2015Braid et al, 2012;Dupuis et al, 2014;Gladney et al, 2014;Cambeses et al, 2015).…”

Changes in Wood Anatomy in Tree Rings of Pinus pinaster Ait. Following Wounding by Flash Floods

“…Desde la década de los setenta, y en paralelo a los estudios locales, comienzan a elaborarse síntesis regionales sobre los materiales ígneo-metamórficos del Sistema Central, destacando las revisiones realizadas por: Bard et al (1970), Bischoff (1972), Capdevila et al (1973), Aparicio et al (1975, Capote et al (1977, Bellido et al (1981), , García Cacho y Aparicio (1987), y Villaseca et al (1993). Trabajos de síntesis podrían considerarse igualmente las memorias y mapas geológicos, tanto a escala 1:200.000 como a escala 1:50.000, que se publican a inicios de la década de 1980de (IGME, 1981ade y 1981bArribas y Jiménez, 1982) Capote (1991); Marín y Campos (1992); Rivas et al (1993);Campos Egea et al (1995);Hernán (1996);y Pérez et al (2001).…”

LP-HT anatectic processes and lithological heterogeneity in the Mindelo Migmatite Complex (NW Portugal)

“…According to their chemical and mineralogical composition, the variscan granitoids can be grouped into two families: peraluminous, two-mica granites and leucogranites and biotite (± Crd ± Hnb) granodiorites. The widespread occurrence of Crdbearing granites has led some petrologists to suggest an intermediate series or family of "granites of mixed features" (Capdevila et al, 1973;García-Moreno et al, 2007). Most of leucogranites are related to the principal metamorphic episodes and their emplacement is associated with the last deformation phase (D 3 ) and the development of ductile extensional shear zones (Ferreira et al, 1987;Escuder Viruete et al, 1994;Díez Balda et al, 1995;Valle Aguado et al, 2005;Azevedo & Valle Aguado, 2013).…”
