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.[1] 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.[2]

A recent relaxation of regulations by the government of Greenland has opened up the possibility of large-scale mining by Greenland Minerals and Energy.[3] The Kvanefjeld site is part of the Ilimaussaq intrusive complex.[4] Rare earths and uranium are typically concentrated in lujavrite.[5] 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.[6]
Kvanefjeld is already known among mineral collectors as a source of fluorescent minerals such as tugtupite and chkalovite.[7] Coordinates: 60°59′N 46°00′W / 60.983°N 46.000°W
