Belyankinite is a hydrous calcium titanium oxide. Gerasimovskii & Kazakova (1950) named the mineral after Dmitrii Belyankin (1876-1953), petrologist at the Russian Academy of Sciences (Moscow). Belyankinite forms by alteration of lomonosovite and murmanite. Belyankinite is poorly crystallized and consequently lacks a defined unit cell (Fleischer, 1952). The mineral is listed with questionable status on the IMA list of mineral species.
Belyankinite forms a tan cleavage on compact fibrous aegirine. From the collection of E.R. Laskowski (1949-2020), a mining engineer who retired to Tucson, Arizona.
