Tonalitic to trondhjemitic dykes within metabasic lower-crust rocks, Serre Massif, Calabrian-Peloritan arc.

A section of continental lower crust, metamorphosed under granulite facies conditions, outcrops in the Serre massif, southern sector of the Calabrian-Peloritan arc. The section consists of gabbroic rocks, ultramafic and opx-bearing felsic granulites. These rocks are intruded, mainly in the Curinga ourcrop, by leucocratic dykes. On the basis of the whole rocks geochemical analyses performed using ICP-MS and mineral chemistry the studied rocks shows tonalitic-trondhjemitic composition with metaluminous and calcalkaline characteristics. The Curinga leucocratic dykes are compared with some plutonic masses of the Calabrian-Peloritan arc, i.e., the Capo Vaticano tonalites, the Cittanova granites and the Squillace- Petrizzi tonalites. As far as their origin, a partial melting of basic, lower crust rocks is suggested.
