Seidozerite - Sold

Seidozerite is a sodium zirconium manganese titanium silicate fluoride. Semenov et al. (1958) named the mineral after Lake Seidozero, near its discovery site. Belov & Organova (1962) established the currently accepted formula for seidozerite, while comparing its crystallography to that of lomonosovite. Sokolova & Cámara (2017) chose seidozerite as the archetype for a supergroup of titanium silicate minerals. The seidozerite supergroup includes the rinkite, bafertisite, lamprophyllite, and murmanite groups; a total of 48 species at the time of this writing.

Seidozerite forms a brown fibrous mass 12 mm across in a matrix of microcline and aegirine. From the type locality. Part of the collection of E.R. Laskowski (1949-2020), a mining engineer who retired to Tucson, Arizona. Fersman Museum and A.L. Kidwell labels also accompany this specimen.
