Embedded Fenaksite crystals from Khibiny, Kola, Russia– micromount as unique piece

This micromount shows embedded Fenaksite crystals with brown to reddish-brown coloration on a light to dark gray matrix. The crystals are compactly developed and stand out clearly from the surrounding rock through their color and luster. This unique specimen comes from the Khibiny Mountains on the Kola Peninsula, Russia.

Geology & Origin

Fenaksite is a rare alkali titanium silicate particularly associated with alkaline rock complexes. The Khibiny Mountains on the Kola Peninsula form one of the world's important alkaline intrusive complexes and are renowned for their exceptionally diverse mineralogy, including numerous rare mineral species. Fenaksite occurs there in association with alkaline rocks and their late-magmatic to hydrothermal mineralization
