Poudrette quarry (Demix quarry; Uni-Mix quarry; Desourdy quarry), Mont Saint-Hilaire, Rouville RCM, Montérégie, Québec, Canada FOV 2.5 x 3.0 mm. Self collected by Modris B Sept 1996. Not analyzed so it's "donnayite group". But no one seems to post under that even though visual ID of donnayite/welloganite group minerals is unreliable at MSH. The child photo is stereo. |

Poudrette quarry (Demix quarry; Uni-Mix quarry; Desourdy quarry), Mont Saint-Hilaire, Rouville RCM, Montérégie, Québec, Canada FOV ~ 2 cm. Individual xls ~ 3-4 mm diameter. Via Jean-Yves L. This is classic MSH donnayite-(Y). But I don't know if it is from an analyzed find so strictly speaking it is "donnayite group". Oct 2009: Updated to a "macro" view. |
