Lithospheric Mantle Evolution beneath the Eifel (Germany): Constraints from Sr–Nd–Pb Isotopes and Trace Element Abundances in Spinel Peridotite and Pyroxenite Xenoliths

The Pb isotope compositions of amphiboles and clinopyroxenes in spinel peridotite and pyroxenite mantle xenoliths from the intra-plate Quaternary volcanic fields of the Eifel province (Germany) are strongly correlated with their Sr–Nd isotope and trace element compositions. High-temperature anhydrou...

Description
Summary:The Pb isotope compositions of amphiboles and clinopyroxenes in spinel peridotite and pyroxenite mantle xenoliths from the intra-plate Quaternary volcanic fields of the Eifel province (Germany) are strongly correlated with their Sr–Nd isotope and trace element compositions. High-temperature anhydrous xenoliths from a depth of around 60 km have trace element and Sr–Nd–Pb isotope compositions similar to the depleted source of mid-ocean ridge basalts (Depleted MORB Mantle, DMM). Amphibole-bearing xenoliths from shallower depths (
