The Krutaya pegmatite, where fluor-rossmanite was found, is one of the oldest-known in the Malkhan field. It was discovered by the geological expedition โ€œSosnovgeologiyaโ€ in 1981, i.e., two years before the Malkhan field itself. The pegmatite dike is 120 m long and up to 5 m thick, with a poorly defined zonal structure. Most of the body is composed of graphic pegmatite, consisting of potassic feldspar, quartz, and albite. The central part of the pegmatite contains orange spessartine, muscovite, beryl, and tourmaline in addition to individual miaroles (up to 0.3 x 0.2 m in size) lined with quartz crystals.

A tourmaline crystal is unique in terms of the quantity of tourmaline supergroup species it contains โ€“ as many as eight of them. Its dark brown core consists of unusually Mn-rich fluor-tsilaisite, princivalleite and a potentially new tourmaline species, a Mn2+ -F-analogue of foitite, are
also recorded in this zone. The greenish-yellow intermediate zone consists of Mn-rich fluor-elbaite with the average chemical composition, a few analyses of this zone correspond to the compositional field of darrellhenryite. This zone is surrounded by a Mn-poor, light pink zone composed mainly of fluor-rossmanite. This zone also includes local chemical compositions corresponding to rossmanite and its oxy-analogue, another potentially new
tourmaline species. Finally, the yellowish-green peripheral zone consists of late-generation, Mn-bearing fluor-elbaite.
