Abstract

The Panarea Volcanic Group (PVG) is a group of emergent islands rising from the truncated cone of an underwater edifice inthe eastern sectorofthe Aeolian Island Arc in the Tyrrhenian Sea, Italy. Selected lava units from the main island of Panarea and some of the nearbyislets were analysed for their major and trace element compositions to the dataset available in the literature. Major mineral phases were identifiedasplagioclase±clinopyroxene±orthopyroxene±olivine ± amphibole ± mica. The lavas of this study range from andesitetorhyolitewithmajor element compositions equivalent to previously published data. Pyroxene geobarometry suggests a polybaric distribution to crystal fractionation, beginning at the Moho, and continuing to a shallow magma reservoir,atapproximately0.8kmdepth.AplotofNd143/Nd144 vs. Sr87/Sr86 show the compositions of Panarea overlap with the compositions of the eastern and central Aeolian Arc, while Pb208/Pb204 vs. Pb206/Pb204 do not overlap, but fall between the central and eastern arc values. As major and trace element concentrations, and isotope compositions of the lavas of this study overlap most consistently with lava compositions from thecentralandeasternAeolianArc,indicatingPanareashould be considered an Bintermediate^ volcano in the arc
