Upper mantle beneath neovolcanic zone of the Bohemian Massif: xenoliths and their host basalts
We propose a complex and spatially extensive study of lithospheric upper mantle of the Bohemian Massif, based on peridotite xenoliths and their host basalts. Chemical, Pb-Sr-Nd isotopic, and microfabric analyses performed on large suite of samples will show the 3-D or 4-D variation of composition, metasomatic transformation, deformation, and seismic properties of the upper mantle beneath the 500km long zone of Cenozoic neovolcanics. The results will bring basic knowledge on physico-chemical properties of the upper mantle in the Bohemian Massif, which is largely missing. The neovolcanic zone studied includes two tectonic domains with clear differences of their lithospheric structures: the Ohře Rift and the Labe/Odra Zone. The proposed research is expected to shed light on processes which led to quasi-synchronous volcanism in such contrasting regions. The spatial variations of the studied parameters of the basalts and xenoliths can indicate the interference between the Variscan terrane architecture, upper mantle structure/composition and neovolcanism.
