... 291 and 285 Ma [36]). This massif also contains ultrabasic/basic-to-intermediate rocks associated with late-Variscan calc-alkaline granites, showing mineralogical and geochemical characteristics typical of appinite suites, with cumulate hornblendites and gabbros crystalized from K-rich and fluid-rich magmas, and a complex mingled zone between diorites and biotite granodiorites [37,38]. ...

... Thermobarometric estimates, using the twopyroxene thermometer of Brey and Köhler (1990), provide higher equilibrium temperature (T) for harzburgites (1062 ± 29 ºC) and websterites (up to 1257 ºC) than for lherzolites (972 ± 89 ºC) (Galán et al., 2011). More recently, Fernández-Roig and Galán (2015) found that equilibrium T in lherzolites decreases from those with protogranular microstructure (1082-950 ºC) towards porphyroclastic (959-867 ºC) and equigranular lherzolites (995-829 ºC), and that estimates using integrated compositions of clinopyroxene and/or clinopyroxene porphyroclasts and mutual exsolved lamellae (1125-955 ºC) are higher and comparable to those registered by protogranular lherzolites and harzburgites. Decreasing T from protogranular towards porphyroclastic and equigranular peridotites was also found in similar xenoliths from the Carpathian-Panonian region (Szabó et al., 2004). ...

... The BA-index has values between 0 and 1, the formula is shown as 0.5(2 − (P010/(G010 + P010)) − (G100/ (G100 + P100))). Generally we classified axial-[010] as having a BA-index lower than 0.4, orthorhombic as between 0.4 and 0.6, and axial-[100] as higher than 0.6 as used previously (Fernández-Roig et al., 2017;Puelles et al., 2016;Zaffarana et al., 2014). ...

... The latter are heterogeneous paragneisses whose contacts are outlined by ultramafic rocks interpreted as mantle fragments incorporated into the subduction zone (Gil Ibarguchi et al., 1999). The eclogites have been interpreted as a metamorphosed volcano-sedimentary sequence (Albert et al., 2012) while the granulite protoliths are uncertain, potentially including volcanic-arc upper crust (Galán and Marcos, 1998). The ultramafic rocks are exposed in three main massifs; the largest, Herbeira (~12.5 km 2 ), is the object of this study (Fig. 1c). ...

... Montero and Floor, 2004;Valverde-Vaquero et al., 2005;Dias da Silva et al., 2016), the Beira Baixa-Central Extremadura tonalite-granodiorite belt of I-type affinity (Rubio-Ordóñez et al., 2012), basaltic and albititic layers in the WALZ (e.g. Roel, 1994;Corretgé et al., 2004), volcanic rocks in the Iberian Ranges (e.g. Álvaro et al., 2008), and the basaltic and volcanosedimentary Castro Fm. and the cineritic level within the Armorican Quartzite in the CZ (e.g. ...

... Several studies on the petrology and geochemistry of the CVZ volcanic rocks and their associated mantle and crustal xenoliths have been published in the last decades (Araña et al. 1983;López-Ruiz and Rodríguez-Badiola 1985;Martí et al. 1992;Neumann et al. 1999;Cebriá et al. 2000;Galán et al. 2016). These volcanic rocks are homogeneous in their major element contents. ...

... There are several generations of calc-alkaline granites and * * * alumnious leucogranites that intruded between 307 and 284 Ma. Syn-kinematic intrusions show a close spatial relation to high-grade metamorphic rocks and migmatites, whereas post-kinematic intrusions mainly occur in zones of low-grade metamorphism (Corretge et al., 1990). Based on tectonostratigraphic relations, the Central Iberian Zone is divided into Autochthonous and Allochthonous sequences that both are dominated by Ordovician to Carboniferous sedimentary rocks, but differ in metamorphic grade and deformation style and most importantly their relation to older rocks. ...

... Relict crystals from the starting material may be present if the starting material was not fully melted (Mutch et al., 2016). The relatively small size of experimental products also enhances EPMA uncertainty relative to natural crystals, because the interaction volume of the electron beam may directly enter other phases, and neighboring phases may inf luence the measurement through secondary f luorescence (Llovet & Galan, 2003;Fig. 1d). ...

... Such a value (i.e., Ce N < 0.3 and La N < 0.1) is more than one order of magnitude lower than those in our samples. On the other hand, the LREE-depleted REE patterns shown here are quite similar to those reported by many previous studies (e.g., Bedini et al., 1997;Xu et al., 2003;Mü ntener et al., 2004;Ying et al., 2006;Le Roux et al., 2007;Soustelle et al., 2009;Bianchini et al., 2011;Ackerman et al., 2014;Galán and Oliveras, 2014), which have clearly demonstrated that such REE patterns are due to extensive interaction of mantle rocks with LREE-depleted melts. Second, Al 2 O 3 and CaO contents are nearly linearly correlated with MgO contents in our samples (Fig. 5). ...

... Peridotite xenoliths exhumed by Cenozoic alkaline volcanoes are an essential source of information about the nature and evolution of the subcontinental lithospheric mantle (e.g., Downes, 2001). In the Iberian Peninsula there are four main Cenozoic volcanic fields that contain significant mantle xenoliths suites: SE Spain (Avanzinelli et al., 2020;Beccaluva et al., 2004), Olot (Bianchini et al., 2007;Galán et al., 2008), Levante (Seghedi et al., 2002) and Calatrava (Ancochea and Nixon, 1987). ...
