HYDROTHERMAL QUARTZ VEINS
- Large hydrothermal quartz veins are present both north and south in the country and some have been in production for silicon metal, silicon carbide and ferrosilicon. At present two large high grade veins are being closely examined for possible future mining: The very large Nasafjell veins by the Arctic Circle (front photo) where Elkem ASA currently awaits governmental approval, and the Nesodden deposit by the Hardangerfjord in Southern Norway, where Nordic Mining ASA is developing a large quartz vein for industrial operation.
