The augen gneisses of the Peloritani Mountains (NE Sicily): Granitoid magma production during rapid evolution of the northern Gondwana margin at the end of the Precambrian

Source-inherited compositional diversity in granite batholiths: The geochemical message of Late Paleozoic intrusive magmatism in central Calabria (southern Italy)

“…These rocks have indeed restitic features, consistent with the extraction of large volumes of granite melt, estimated as making up to 66 vol% in the most depleted metapelites (e.g., Fornelli et al, 2002). On the contrary, derivation of the most felsic granites by partial melting of felsic metaigneous sources, such as the Late Cadomian granitoids (Fiannacca et al, 2013;Micheletti et al, 2007), is excluded by the much higher ( 87 Sr/ 86 Sr) 290 ratios of the latter rocks.…”

“…Finally, the upper amphibolite-facies augen gneisses forming sizeable bodies throughout the CPO (Fiannacca et al, 2013;Micheletti et al, 2007) have restricted εNd values that match with only a few of the granitoid rocks and are characterized by a much more radiogenic 87 Sr/ 86 Sr signature. …”

“…Moreover, there is no clear evidence for the presence of a suitable mantle-related mafic end member since the only possible candidates, i.e., the rare quartz Rottura et al (1989, 1990, Fornelli et al (1994); Serre Massif metagabbros and mafic granulites after Caggianelli et al (1991); Peloritani Mts amphibolites after Fiannacca (2000). Fields of Serre Massif metapelite (dashed line) and metagraywacke (dashed-dotted line) migmatites after Del Moro et al (2000); fields of CPO metasedimentary rocks (continuous line) after Rottura et al (1989), Caggianelli et al (1991); Fiannacca et al (2005), Williams et al (2012); CPO augen gneisses (dotted line) after Micheletti et al (2007), Fiannacca et al (2013). Other symbols as in Fig.…”

Timescales and mechanisms of batholith construction: Constraints from zircon oxygen isotopes and geochronology of the late Variscan Serre Batholith (Calabria, southern Italy)

“…21 contexts can occur in less than 15 Ma (e.g., Fiannacca et al, 2013;Jeon et al, 2012;Matzel et al, 2006;Schulmann et al, 2002).…”

The endemic vascular flora of Peloritani Mountains (NE Sicily): Plant functional traits and phytogeographical relationships in the most isolated and fragmentary micro-plate of the Alpine orogeny

“…The current structure of the CalabrianPeloritani Orogen (CPO) consist of a nappe-pile edifice, involving distinct tectonic slices of metamorphic basement rocks characterized by different litho-types and distinct tectonic metamorphic evolutions, plus some Mesozoic-Coenozoic sedimentary sequences (Cirrincione et al 1999;Appel et al 2011;Fiannacca et al 2013). The complex geological and tectonic history is reflected by the rugged morphology of Peloritani, counting several mounts, hills and deep valleys, in spite of the relatively low altitudes.…”
