Loparite-(Ce)

Oxide mineral

Loparite-(Ce) is a granular, brittle oxide mineral of the perovskite class. It is black to dark grey and may appear grey to white in reflected light on polished thin section with reddish brown internal reflections. It has the chemical formula of (Ce,Na,Ca)(Ti,Nb)O3. Nioboloparite is a variation of Loparite-(Ce) containing niobium

Loparite occurs as a primary phase in nepheline syenite intrusions and pegmatites. It is also found replacing perovskite

Loparite was first described for an occurrence in the Khibiny massifs, Kola peninsula. * Crystal structures of loparite * * *
