Cesstibtantite and Simpsonite, UV-avtive, from Voronya Tundra, Khibiny, Kola, Russia – miniature specimen as unique piece
This rare miniature specimen from the famous Khibiny region on the Kola Peninsula contains Cesstibtantite and Simpsonite hosted in a light-colored pegmatite matrix. The marked areas indicate the presence of these rare mineral species, which occur in association with complex tantalum, niobium and antimony mineralization. Visible individual crystals are only small or partly embedded within the matrix on this specimen. Nevertheless, it represents an interesting collector specimen from a world-renowned locality for rare minerals. The UV activity of the contained minerals adds further appeal, especially for collectors of fluorescent minerals.
Geology & Origin
The Worony Tundra area within the Khibiny Massif on Russia's Kola Peninsula is one of the world's most important alkaline pegmatite localities. These unusual geological environments have produced numerous rare minerals, including species known from only a handful of occurrences worldwide. Simpsonite is a rare tantalum oxide, while Cesstibtantite is among the unusual antimony-bearing minerals associated with this locality. The Khibiny region is internationally recognized for its exceptional mineral diversity and remains one of the most important sources of rare collector minerals from alkaline pegmatites.
