Petersenite-(Ce) Locality: Poudrette quarry (Demix quarry; Uni-Mix quarry; Desourdy quarry; Carrière Mont Saint-Hilaire), Mont Saint-Hilaire, La Vallée-du-Richelieu RCM, Montérégie, Québec, Canada The petersenite-(Ce) xls are ~ 5 mm. Via Jean-Pierre Beckerich. MOB coll. This is from the Poudrette pegmatite. The black aegirine prisms are all broken. The petersenite-(Ce) apears very fresh and unaltered (but some of it has a thin orangey coating.) It was associated with adamsite-(Y). It has very strong REE absorbtion lines but has not been analyzed. So I can't completely rule out other REE bearing burbankite family species (such as calcioburbankite). Mineral
