Pegmatitten er fulgt over 3-400 m. Sannsynlig maksimal tykkelse er 20 m. Varierer mye fra 1 m og oppover i tykkelse. Har endel inneslutninger av glimmerskifer og gneis. Pegmatitten skjærer foliasjonen på de overliggende glimmerskifre. Har stedvis skriftgranitt-tekstur; enkelte partier er aplittiske. Vanlig kornstørrelse for feltspat er 1-3 cm, for kvarts 1-10 mm og for glimmer 0.5-2 mm.
