Kassite is a calcium titanium oxide hydroxide. Kukharenko et al. (1965) named the mineral in honor of Nikolai Grigorievich Kassin (1885-1949), geologist. Kassin discovered the Afrikanda Massif (Kola Peninsula, Russia), which includes the type locality. Evans et al. (1986) studied kassite from this occurrence in Arkansas, although there was confusion due to its similarity to cafetite. Ultimately, Grey et al. (2003) and Pekov et al. (2004) determined that kassite and cafetite are in fact polymorphs.

Kassite forms a minute rosette in vuggy matrix, consisting of albite with minor aegirine and titanite. This specimen carries a vintage Mineralogical Research Company label.
