Kvanefjeld (or Kuannersuit), in Greenland, is the site of a mineral deposit, which is claimed to be the world's second-largest deposit of rare earth oxides, and the sixth-largest deposit of uranium. There are also substantial sodium fluoride deposits, and Kvanefjeld is thought to be one of the largest multi-element deposits of its kind in the world.
A recent relaxation of regulations by the government of Greenland has opened up the possibility of large-scale mining by Greenland Minerals and Energy. The Kvanefjeld site is part of the Ilimaussaq intrusive complex. Rare earths and uranium are typically concentrated in lujavrite. Lujavrite, a dark agpaitic nepheline syenite, occurs as an internal layer in the north Ilimaussaq complex. The uppermost sections generally have the highest rare earth elements, uranium and zinc grades.
Lujavrite is a rare variety of nepheline syenite having amphibole, aegirine pyroxene, nepheline and feldspar. The red spots in the rock are crystals of the rare halide mineral villiaumite (NaF - sodium fluoride).
The Kvanefjeld project is 100% owned by ASX-listed Greenland Minerals and Energy Limited.
Kvanefjeld is already known among mineral collectors as a source of fluorescent minerals such as tugtupite and chkalovite.
