A rare-element REE monazite type granite pegmatite hosted in amphibolitic rocks quarried for feldspar located about 100m south of the road Tveit-Dalane on the Tveit Farmland. The pegmatite dike was about 10 m wide.

Known especially for its good specimens of columbite-(Fe), muscovite and almandine. For micro-crystal collectors, the superb epitaxial intergrowth of xenotime-(Y) and zircon are also worth mentioning.

Bjørlykke locality n° 3.

Corneliussen area 1, locality 2.

Corneliussen additionally registered two prospects, one a couple of meters outside the quarry, the other one inside the quarry. The coordinates are: 58.40426N, 7.87689E and 58.40444N, 7.87742E.
