Cerite is a complex silicate mineral group containing cerium formula (CeLaCa)9(MgFe+3)(SiO4)6(SiO3OH)(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 carbonatite gave 35.05% Ce2O3 and 30.04% La2O3.Cerite was first described in 1803 for an occurrence in Bastnäs in Västmanland Sweden.
