Adamsite-(Y) 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 FOV ~ 1.3 cm high. Via Jean-Pierre Beckerich. MOB coll. The orange/red stuff is granular rhodochrosite with a few small rhombs - listed for completeness. There may also be shomiokite-(Y) but if so, it's behind the adamsite - see side view in child photo. Another child photo shows another group with orthorhombic looking xls. Perhaps more shomiokite - but I suspect not in this case. Mineral
