| Feltet med ultrabasiske bergarter utgjør ca. 0.5 km². Det består hovedsakelig av bergarten sagvanditt (enstatitt- og karbonatbergart). Den er porfyroblastisk med 1-4 cm store enstatitt-krystaller i en fin-middelskornet grunnmasse som vesentlig består av magnesitt. Ellers finnes endel serpentin-asbest i årer i bergarten. Det er ikke sett partier med ren olivin. |
