Abstrakt (česky)
   REE-bearing minerals from the Skalna Brama pegmatite were reported by Websky (1865), Traube (1888) and Gajda (1960 a,b). The pegmatite is located within granite of the Karkonosze Massif. It forms lens-like body up to 5 m thick with internal structure comprising from the rim inwards: granitic and graphic zone, blocky K-feldspar and massive quartz core. The rock-forming minerals of the pegmatite include quartz, microcline, oligoclase, biotite. Ilmenite, chlorite, hematite, gadolinite, fergusonite, monazite, zircon, xenotime, uraninite, pyrite and arsenopyrite are accessory minerals. Zirconolite was found as aggregates of needle-like branching crystals up to 4 cm long and up to 0.2 cm wide in massive pink microcline and grey quartz. It shows brown to black color and semi-vitreous to resinous lustre.
