Abstract
The occurrence of strong negative phases at 7,5s Ps delay, may indicate body of partial melt at ca. 65km depth beneath
western Bohemian Massif (see Figure below). To test the hypothesis, we studied 2 suites of lithospheric
mantle xenoliths, different in age (P-T-fO2, petrophysical, geochemical and isotope [Sr, Nd, Pb] constraints). The
xenoliths from 25 Ma old volcanics are spinel lherzolithes. The suite from 0.3 Ma old volcanics represent cumulates,
porous fragments of magmatic veins or porous wehrlites. These samples are strongly altered by mantle metasomatism
(changes of fO2, geochemical constraints, density/porosity).
