Originální abstrakt

This contribution presents a new laser ablation inductively-coupled plasma mass spectrometry (LA-ICP-MS) U-Pb age for magmatic apatite from ultramafic lamprophyres exposed in the Klunst quarry in Lusatia (south-eastern Saxony, Bohemian Massif). The lower intercept age of 129.3 +/- 2.2 Ma in the Tera-Wasserburg Concordia diagram confirms the previously published K/Ar and 40Ar/39Ar ages of phlogopite phenocrysts from similar ultramafic lamprophyres of the Klunst quarry. Therefore, it is possible to conclude that these ages indicate that the Klunst lamprophyres represent the oldest mantle-derived magmatic products related to incipient Alpine orogeny that affected the foreland of the Bohemian Massif.
