Annotation	The statistical evalution of newly measured data of the dyke swarm orientations show close structural affinity between dykes of lamprophyres and semilamprophyres, and their considerable structural difference from felsic dykes. The analysis of intrusive geometrics of bodies of hypabyssal rocks as vell as the difference in strike patterns of the dyke swarm rocks indicate a change in regional stress field in the Eger Rift at around 30 Ma.
