Iblei volcanoes

Sr-Nd-Pb isotope variation along the Aeolian arc represents a part of a larger hyperbolic array connecting the Na-alkaline rocks of Etna-Iblei-Ustica and Tuscany (Figs. 7.6, 7.17). Most of the western and central Aeolian islands plot near to the low-Sr, high-Nd-Pb end-member, whereas the Stromboli volcanics plot away from Etna together with Campanian volcanoes and Emici-Roccamonfina KS rocks. However, the isotopically most primitive rocks from Alicudi have low Sr-isotopic ratios that fall outside the trend (Fig. 7.17). 

The isotopic similarity of some Italian volcanoes, such as Mt. Etna and Iblei, with Na-alkaline and tholeiitic rocks from central and west-...
