| Abstract: | |
| The present publication gives a short description of the most common rare elements of the Norwegian pegmatites and the Norwegian rare-element-bearing minerals. The rare-element-bearing minerals in the Norwegian granite pegmatites are: Uraninite (norw.: uranbekerts) (incl. brøggerite, cleveite, and uranniobit), chrysoberyl, thorite (incl. orangit), allanite (Norw.: ortitt), gadolinite, hellandite, titanite (sphen) and yttrotitanite (keilhauite), thortveitite, zircon (incl. alvite and cyrtholite), beryl, phenacite, fergusonite (incl. risørite), euxenite (incl. blomstrandine, polycrase and priorite), yttrotantalite, samarskite, columbite and tantalite, monazite, xenotime, ilmenorutile, microlite, betafite, scheteligite, rare-earth-bearing garnet, yttrofluorite, parisite and kainosite. According to their mode of formation the Norwegian granite pegmatites may be divided into two groups: the magmatic pegmatites and the pegmatites which are of hydrothermal-pneumatolytic origin. The mineral parageneses of the granite pegmatites in the different pegmatite areas show some characteristic features which indicate a different distribution of the rare elements. |
