Abstract (in english)
   Based on new outcrops of ultramafic alkaline lamprophyres and alkaline basalts in the Lusatian Granodiorite Complex (Klunst quarry), structural and petrological relations to the other dyke swarms could be reported. The lamprophyric dykes cross-cut older microgabbro stocks and alkaline basalts. Geochemical data and structural relations of the lamprophyres to NE-trending normal fault systems favour the attachment of the dykes to extensional tectonics before the "pre-rift magmatism" of the Eger Graben. K-Ar dating gave an age of 130 +- 5 Ma. A petrogenetic model for the succession of basaltic and lamprophyric magmas has been discussed
