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. Click on the images for...

0334 Vesuvianite, Diopside, Jeffrey Mine (Jeffrey Quarry; Johns-Manville Mine), Asbestos, Les Sources RCM, Estrie, Quebec, Canada

A small specimen of manganoan vesuvianite crystals with transparent diopsides. The perfectly terminated vesuvianites have varying colour from intense purple to very pleasing apple yellow-green and some gemmy areas. With exemplary lustre and good light reflection. Diopsides are transparent squares. Width of view of closeup photo 6mm. Stack of 50...

3539 Ancylite-(Ce), Albite, Aegirine, Burbankite, Poudrette quarry, Mont Saint-Hilaire, La Vallée-du-Richelieu RCM, Montérégie, Québec, Canada

Colourless to greyish, and pinky-orange crystals of ancylite-(Ce), or possibly calcioancylite in small cavities in albite. In the second photo, white (probable) calcioburbankite (Type Locality). You can see the hexagonal cross section if you look closely. The label said burbankite. Width of view 3mm and stack of 50 images (ancylite)...

ncat ANK MSH126 Rhodochrosite, Aegirine, Poudrette quarry, Mont Saint-Hilaire, La Vallée-du-Richelieu RCM, Montérégie, Québec, Canada

Deep sharp red-brown rhombohedral crystals, one perched on aegirine crystal. There are also colourless reticulated crystals below right of centre. Maybe albite? One small area on top of rhodochrosite (not in photo) fluoresces orange. Ex Noel and Ann Kennon Collection. Ex Jean Pierre Beckerich. Width of view 11.5mm. Stack of...

ncat ANK MSH147 Calcioburbankite, Petersenite-(Ce), Siderite, Hilairite(?), Poudrette quarry, Mont Saint-Hilaire, La Vallée-du-Richelieu RCM, Montérégie, Québec, Canada

As with many MSH specimens, you don’t always know what you’ve got! White to tan calcioburbankite on hexagonal prismatic petersenite-(Ce). Many of the brown crystals, the lighter ones, are siderite, but some, the darker brown ones, fluoresce orange, maybe hilairite? There are tiny thin plates of an unidentified mineral that...

ncat ANK MSH71 Pectolite, Phlogopite, Poudrette quarry, Mont Saint-Hilaire, La Vallée-du-Richelieu RCM, Montérégie, Québec, Canada

Phlogopite pseudohexagonal plates on prismatic colourless pectolite. Pectolite crystals have zoned fluorescence, pink with blue caps. Ex Noel and Ann Kennon. Ex Jean Pierre Beckerich. Width of view 5.75mm. Stack of 60 images. Comparison image width of view 11.5mm. Click on the images below for a higher resolution version. For...

ncat ANK MSH123 Epididymite, Franconite, Analcime, Muscovite, Pyrite, Albite, Poudrette quarry, Mont Saint-Hilaire, La Vallée-du-Richelieu RCM, Montérégie, Québec, Canada

Colourless twinned epididymite with cream hemispheres of franconite(?), with tiny silver pseudohexagonal muscovite, and tiny pyrite crystals, minor albite, all on analcime. There is also a prismatic hexagonal crystal of epididymite pointing down to the bottom left just below the yellow arrow. Ex Noel and Ann Kennon Collection. Ex Jean...

ncat ANK MSH100 Hilairite, Gaidonnayite, Poudrette quarry, Mont Saint-Hilaire, La Vallée-du-Richelieu RCM, Montérégie, Québec, Canada

Type Locality for hilairite. Brown hilairite with colourless/grey twinned gaidonnayite. Hilairite fluoresce green under longwave UV, but gaidonnayite doesn’t appear to respond. Ex Noel and Ann Kennon Collection. Ex Jean Pierre Beckerich. Width of view 11.5mm. Stack of 114 images. Click on the image below for a higher resolution version.

ncat ANK MSH1 Ferrokentbrooksite, Poudrette quarry, Mont Saint-Hilaire, La Vallée-du-Richelieu RCM, Montérégie, Québec, Canada

Small orange crystals. Originally labelled as kentbrooksite, but probably ferrokentbrooksite and most likely collected before that mineral was described as a new species. Ex Noel and Ann Kennon Collection. Ex Jean P Beckerich. Width of view 5.75mm. Stack of 42 images. Type Locality. Click on the image below for a...

7411 JL1902 Synchysite-(Ce), Pyrite, Poudrette quarry, Mont Saint-Hilaire, La Vallée-du-Richelieu RCM, Montérégie, Québec, Canada

Yellowish pseudohexagonal plates of synchysite-(Ce) with tiny pyrite crystals sprinkled on them. White albite crystals at the base. Ex Joan Lamond Collection. Acquired by Joan in 1993 from Cynthia Peat (peatite-(Y)). Width of view 3.5mm. Stack of 30 images. Click on the image below for a higher resolution version…
