Undeland 2 (Berylbruddet), Undeland (Unneland; Underland), Evje og Hornnes kommune, Aust-Agder fylke, Norge


Located about 200m South of the Undeland 1 quarry.

Andersen's (1931) designation of the quarry: "Underland II (Berylbruddet)" (p. 101).
Bertil Otter (personal communication) describes this locality as two small pits, divided by granitic gneiss.

Theodor Gautestad worked the pegmatite for thortveitite in the 1950's. In the collection of the Evje og Hornnes geomuseum is a single thortveitite crystal from this locality.

The two prospects differ considerably regarding their paragenesis.

The coordinates are given for the largest and best visible prospect.

The other one is located here:
58.58285,7.90465

Otter was shown this locality in 1981 by Theodor Gautestad. He subsequently bought the rights to collect minerals for a couple of years.
