Thumbnail (1-3cm)

Description

Not a beauty, but a very interesting and unique rare borate association. While the original label states it comes from the type locality for frolovite, the specimen appearance (part of a drill core) and general look point at the Solongo B deposit, more than 3000 km away!

The brownish-yellow material making most of the rock is likely fedorovite, while frolovite forms the whitish, ill-defined whitish veins crisscrossing the whole specimen. Orange roweite crystals are included in several spots, while an unconspicuous white scaly mineral shows the bright orange fluorescene in shortwave UV typical of turneaureite, a rare arsenate of the apatite group.
