Andersen (1923) describes Skåtøy as being unusually rich in pegmatites. They can be up to 60 m wide, but on average they are 10-20 m wide. Some can be followed for more than a kilometer, often crossing the sea between islands.

Andersen describes one quarry where there has been production. There were several prospects too, but no production.
