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.
