Scanning electron microscopy image of the newly found iron-magnesium silicate. Top: SEM-BSE panoramic image of the section containing new magnesium silicate (OL: olivine). The dashed lines indicate the walls of the shock-induced melt vein. The red rectangular area indicates the region enlarged in the bottom BSE image. Bottom: enlarged area depicted in the top panel; elgoresyite (ELG) [(Mg,Fe) 5 Si 2 O 9 ], indicated with the dotted red line, is associated with ringwoodite (RGW), olivine (OL), tetragonal ringwoodite (SPD), taenite (TAE), and MgSiO 3 -rich glass.

Elpidite Locality: Poudrette quarry (Demix quarry; Uni-Mix quarry; Desourdy quarry), Mont Saint-Hilaire, Rouville RCM, Montérégie, Québec, Canada (Locality at mindat.org) Size: 5.5 x 4.3 x 3.5 cm. This is a very rich specimen of the relatively rare hydrated sodium zirconium silicate Elpidite, seen here in a specimen from the prolific Mont Saint - Hilaire locality. They are often seen in single sprays without matrix, but these sprays do occur on matrix and are remarkably well-defined with individual blades up to 2 cm long. Ex. Martin Lewadny Collection.

Embreyite, Vauquelinite, Crocoite Locality: Berezovskoe Au Deposit (Berezovsk Mines), Berezovskii (Berezovskii Zavod), Ekaterinburg (Sverdlovsk), Ekaterinburgskaya (Sverdlovskaya) Oblast', Middle Urals, Urals Region, Russia (Locality at mindat.org) Size: 6.0 x 5.4 x 4.6 cm. This specimen is from the type locality for all three species here, and features rich zones of all three as well. It has prismatic orange crocoite crystals to 2 cm in length. Olive green vauquelinite occurs as chalky, green growths on crocoite. Nestled in a vug are minute orange embreyite crystals. Ex. Harvard University and Phil Scalisi Collections. Mineral
