Nepheline syenite pegmatite (Plumasite-pegmatite type after Barth 1927) located NW of of Skarvevann, near Ørnetind, in the SW part of Seiland Island. It is 4-5 m thick strikes NNW-SSE and dip 90 degree.

Large, rounded crystals of nepheline with a diameter of 1.5m are present in the pegmatite.

Refered to by Hoel & Schetelig (1916) as "Pegmatitic dyke north of Skarvevand".
