Cerite

Silicate mineral group

Cerite is a complex silicate mineral group containing cerium) 9(Mg 3+ )(Si 4) 6(SiO 3OH)(OH) 3. The cerium and lanthanum content varies with the Ce rich species (cerite-(Ce)) and the La rich species (cerite-(La)). Analysis of a sample from the Mountain Pass gave 35.05% Ce 2O 3 and 30.04% La 2O 3.

Cerite was first described in 1803 for an occurrence in Bastnäs in Västmanland The lanthanum rich species, cerite-(La) was first described for an occurrence in the Khibina massif, Kola Peninsula in 2002.
