Abstract
New geochemical and isotopic data are reported for calc-alkaline (CA) volcanics of the Aeolian arc. Three main groups are recognized: the Alicudi and Filicudi volcanics in the western part of the arc; the Panarea, Salina and Lipari (henceforth termed PSL) volcanics in the central part of the arc and the Stromboli suite which makes up the eastern part of the arc. Each group is characterized by distinctive isotopic ratios and incompatible element contents and ratios. 87Sr/86Sr values (0.70352-0.70538) increase from west to northeast, and are well correlated with 143Nd/144Nd (e{open}Nd from +4.8 to -1.5). Pb isotope ratios are fairly high (6/4=19.15-19.54; 7/4=15.61-15.71; 8/4=38.97-39.36), wit..
