ncat VHD15 Thomasclarkite-(Y), Molybdenite, Elpidite, Siderite, Aegirine, Sodalite, Albite, Poudrette quarry, Mont Saint-Hilaire, La Vallée-du-Richelieu RCM, Montérégie, Québec, Canada

Greyish-green prismatic spray of crystals of elpidite (green fluorescence), pale yellow tabular thomasclarkite, silver hexagonal molybdenite, tiny brown siderite, green prismatic aegirine, and sodalite (orange fluorescence), in white albite (pink fluorescence). A yellow arrow points to thomasclarkite and elpidite. Identified by mineralogist Dr. Ian Graham.
