Slobrekka Pegmatite, Frikstad, Iveland, Aust-Agder, Norway
Photo: Olav Revheim
A large rare-element REE gadolinite type granite pegmatite located about 200 m N of the Vestre Frigstad Farm.
The quarry is open for collectors for a fee. One day tickets can be bought at Beryllen Mineralshop (in Kile), Kilefjorden camping, Setesdalen Information senter in Evje and at the nearby farm Rogdevollen. The fee was NOK 50,- p.p./NOK 100,- families in 2002. A leaflet with information and a map are found at the places selling the tickets.
A gadolinite-(Y) crystal weighing about 500kg has been reported from this pegmatite. Bjørlykke (1935) reports that more than 2 tons of gadolinite-(Y) and several hundred kgs of aeschynite-(Y) has been produced from this locality.
An analyis of aeschynite-(Y) (priorite) is published by Schetelig (1922) from Vestre Frigstad. This reference is most probably refering to Slobrekka.
Bjørlykke locality no. 94.
