A granite pegmatite dyke situated in the northern part of the Iveland pegmatite district on the Frikstad Farm land about 700m W of Nedre Frikstad. It was first started as a small feldspar quarry, later it was also worked for rare minerals (thortveitite, gadolinite-(Y) and euxenite-(Y) ). The dyke strikes NW and is more than 100 m long.

Bjørlykke locality n° 90.
