J. Caleb Chappell's Photo Gallery

CQD-YAMSynchysite-(Ce), Pyrite

Multiple photos available
Francon quarry, Montréal, Québec, Canada

Field of View: 150 μm

Fantastically sharp blades of synchysite-(Ce) found in discrete clusters around a small pebble from Francon. The bright blades on each image are the synchysite-(Ce,) and the small blocky crystals found attached to the side are pyrite. Synchysite-(Ce) previously confirmed from Francon via XEDS by Chris Emproto. Imaged on a Zeiss Supra-35VP SEM at the Center for Advanced Microscopy and Imaging at Miami University. J. Caleb Chappell photo, Chris Emproto specimen.

J16-XKPFluorite, Analcime

Multiple photos available
Poudrette quarry, Mont Saint-Hilaire, La Vallée-du-Richelieu RCM, Montérégie, Québec, Canada

Field of View: 60 μm

A spectacular view of hundreds of penetration twins of fluorite from MSH. These fluorites are quite yttrium-rich (see child photo), which is interesting because I can't find any mention of other fluorite samples from MSH containing detectable yttrium by XEDS. These crystals are also just a few hundred micrometers from the phillipsite-K crystals identified on this specimen. Analcime in the lower portion of the image. J. Caleb Chappell image, Chris Emproto specimen, Ex. Jason Smith.

Keywords: yttrium-rich fluorite, twins, twinning, twinned crystals, penetration twins.

3A3-M0UPhillipsite-K, Analcime, Fluorite, Synchysite-(Ce)

Multiple photos available
Poudrette quarry, Mont Saint-Hilaire, La Vallée-du-Richelieu RCM, Montérégie, Québec, Canada

Field of View: 150 μm

A classically twinned phillipsite-K surrounded by a small sea of analcime crystals and associated synchysite-Ce and yttrium-rich fluorites. ID of the phillipsite-K made by X-ray Energy Dispersive Spectroscopy (XEDS), see child photo. First chemical ID of phillipsite-K from MSH as far as I'm aware. Phillipsite-K in the center of the FOV, analcime being the darker crystals to the right of the phillipsite-K, the fluorite being the much brighter cubes to the left, with the more bladed material intermixed with the fluorite being the synchysite-Ce. J. Caleb Chappell image, Chris Emproto specimen, Ex. Jason Smith.

Keywords: Yttrium-rich fluorite, twinning, twinned crystals.

JL8-5AJFranconite

Multiple photos available
Francon quarry, Montréal, Québec, Canada

Field of View: 300 μm

The elusive franconite from Francon. This cluster was plucked off of a weloganite crystal with a few more clusters nearby which are being photographed and posted soon. Identified by X-ray Energy Dispersive Spectroscopy (XEDS), see child photo. J. Caleb Chappell image, Chris Emproto specimen, Ex. Steve Chamberlain.

Keywords: rare species, niobate, franconite group

6L0-295Labuntsovite-Mn, Synchysite-(Ce)

Multiple photos available
Poudrette quarry, Mont Saint-Hilaire, La Vallée-du-Richelieu RCM, Montérégie, Québec, Canada

Dimensions: 5 mm x 4 mm x 4 mm
Field of View: 0.10 mm
Largest Crystal Size: 0.03 mm

Sharp, but small, crystals of Labuntsovite-Mn with a smattering of Synchysite-Ce throughout. Both verified by XEDS, see child photos.

Scanning Electron Microscope image acquired in backscatter detection mode. Labuntsovite-Mn crystals are tabular crystals in the center of the image, Synchysite-Ce crystals are the small bright white spots seen throughout. Scale bar on bottom of image. J. Caleb Chappell image and specimen.
