Euxenite-(Y) - Rose Quartz Pit, Quadeville, Lyndoch Township, Renfrew Co., Ontario, Canada

Posted by Tim Jokela Jr  
An odd looking euxenite. Looks much more like molybdenite with associated yellow ferrimolybdite... a very distinctive combination.

If it is moly with ferrimoly, then we either have a locality problem, or two new species for the rose quartz pit.

I've never seen moly from the rose quartz pit, and have only seen a tiny, tiny bit from the beryl pit, a very similar peg nearby. Needs confirmation from the owners or similar experts.

A quick poke with a pin or examination with low magnification would confirm ID, leaving the locality problem.
It looks a bit odd and for sure it could be an error or mis-id...but on the other hand the image is only 6 mm and the vitreous surface of euxenite (or any other re-nb-ta-oxide for that matter) could for sure appear oddlooking if the light isn't perfect. Also, I checked the persons other images - he seems to be knowing what he's up to.

Hi Tim and Johan;

This piece has the classic shape of the Euxenites that are found at the Beryl Pit, just not as easy to see with the photo. I since used some SIO which removed some of the iron staining, which made it a little cleaner and exposed a bit more of the crystals.
