| 200 m lang pegmatittgang. Gangen varierer i tykkelse fra 0 til 4 m. Det er tatt ut feltspat i 4 mindre brudd, totalt kanskje 100 m³. Gangen har en uregelmessig form, varierer i tykkelse og slynger seg i terrenget. Pegmatitten er kalidominert. Den har feltspatkrystaller på 1-20 cm, og har delvis ren mikroklin. Den utskeidede k-feltspaten er av ren og god kvalitet. Et blandingsprodukt med k-feltspat + kvarts er også skeidet ut. Litteratur Bøckman, K. L., 1948: BA-rapport 5294 |
