Jurassic (159 Ma), ultrapotassic, mica-rich dykes of Kjakebeinet represent the youngest magmatic rock type observed in western Dronning Maud Land, Antarctica; abundant xenoliths are enclosed by the dykes. A petrographical description of the xenoliths and one of the dykes was made to distinguish the...
