J. auteur aut IRD Clocchiatti R. auteur aut IRD text journalArticle eng Nineteen olivine-hosted melt inclusions from seven volcanoes (Etna, Stromboli, Vulcano, Ustica, Alicudi, Marsili and Vavilov) from the southern Italy region were analyzed for abundances of major, trace, and volatile elements, along with Pb isotope ratios (Pb-207/Pb-206, Pb-208/Pb-206 and Pb-206/Pb-204). The systematics of primary volatile (in particular F and Cl) compositions and Pb isotopes identify three main geochemically distinct mantle sources for this region: (1) a component with radiogenic Pb (Pb-207/Pb-206 = 0.780) and low volatile element abundances typified by the Etnean melt inclusions, (2) a component with moderately radiogenic Pb (Pb-207/Pb-206 = 0.798) and high volatile abundance mainly associated with Sommata magmas, and (3) a component with moderate volatile abundances associated with a MORB-like Pb-207/Pb-206 (0.830). The variation of F/Nd and Pb isotopes among the southern Italy melt inclusions reflects mixing between a slightly modified depleted mantle (DMM-EMII mixture) and radiogenic (HIMU-like) mantle components expressed in Pb isotope space, superimposed by slab-derived metasomatic components represented by F/Nd (F/Nd > 30). specialized Melt inclusion Pb isotopes Volatile elements Halogen Arc magma Italy ITALIE 064 334 266-279 2012 0009-2541 https://www.documentation.ird.fr/hor/PAR00010111 10.1016/j.chemgeo.2012.10.033 0009-2541 https://www.documentation.ird.fr/hor/PAR00010111 IRD - Base Horizon / Pleins textes 2013-03-06 2017-08-23 PAR00010111 fre
