The Kuannersuit Plateau is situated in the northwestern part of the Ilímaussaq complex. It's located north-west of the Narsaq River. A small peak at 685 m is named Kvanefjeld Mountain. The plateau consists of different varieties of fine-grained U-Th-REE rich lujavrites (aegirine-, arfvedsonite-, naujakasite-, and brown aegirine lujavrites).
Kvanefjeld is the second-largest deposit of REEs in the world, and the sixth largest uranium deposit (Elements 2012, p. 398); drilling by Greenland Minerals and Energy Ltd. has recommenced in 2010.
At 500m altitude, below the plateau, on the slope of the Kvanefjeld Mountain, there is an old, now abandoned adit, the Kvanefjeld adit, an exploration drift for Uranium. The mine dumps is found below the adit, in a large area.
A large number of tugtupite-bearing albite veins with a complex mineralogy intersects these alkaline rocks (Friis et al. 2004).
Kuannersuite-(Ce) and nabesite were first described from these veins. For detailed information on the mineralogy in these veins see the locality called Tugtupite-bearing albitites.
