Bjertnespegmatitten, Krødsherad, Buskerud, Norge
A large granite pegmatite worked mainly for feldspar until about 1960 located approximately 500 meters north of Bjertnes farm, near Lake Krøderen. The main quarry is an open surface pit measuring roughly 40 by 40 meters. Within the quarry, a tunnel — referred to locally as a synk — descends to underground workings including a large chamber and adits. One of the adits has a separate entrance at a lower level. To the east on the other side of a small creek there are additional workings probably in the extension of the main pegmatite.
The quarry is known for well-developed crystals of monazite-(Ce), large crystals and masses of fresh and altered uraninite with unusual secondary U-minerals formed on fractures in uraninite and more recently also as an efflorescence on the walls and ceilings in the mine. Important to note that several of the secondary uranium phases are impossible to visually identify, and have to either be analyzed or identified based on the associated minerals.
The main underground working located in the main pit is connected to the entrance down in the valley, but both tunnels have areas of clay-like rock which has collapsed and blocked the connection. The east mine tunnel leads about 20 m into the mountain before coming to a collapsed steep (upwards) tunnel. In the main pit underground working there is a shaft going up into the roof (water coming out of it) and is possibly connected to a higher level of the pegmatite workings.
