About MeniayloviteHide

Ca4[F|SO4|SiF6|AlF6] · 12H2O
White to yellowish
Crystal System:
Named by L.P. Vergasova, T.F. Semyonova, V.B. Epifanova, S.K. Filatov, and V.M. Chubarov in 2004 in honor of Igor Aleksandrovich Meniaylov (14 March 1937, Russia - 14 January 1993, Galeras, Columbia), Russian volcanologist, Institute of Volcanology of Far East Branch of the Russian Academy of Sciences, Petropavlovsk-Kamchatskii, for his contributions to the geochemistry related to the Tolbachik Main Fracture Eruption. He died tragically while investigating a volcano in Columbia.
Very closely related to Chukhrovite-(Ca).
