Stibnite on Barite
Deep Post Mine, Lynn District North of Carlin, Eureka County, Nevada, USA
70 x 57 x 45 mm
Bright, silvery-grey Stibnite crystals to 11 mm, forming radiating sprays, are perched on very pale yellow Barite crystals to 15 mm across, ranging from block to tabular in habit. Only a few spots of trivial bruising can be seen with a loupe on a few Barites. This is one of only a few undamaged specimens from a zone consisting of a few small pockets. Casey acquired three specimens in early January 2005 in trade with a geologist working at the mine, and this is the only one with good proportions of both Barite and Stibnite. (Author: GneissWare)

Tourmaline var. Schorl
Pitcapel Quarry, Aberdeen, Grampian Region, Scotland, UK.
12cm tall x 7cm x 6cm
Another view of the above specimen showing quartz-filled strain cracks in the schorl. Ergo, the quartz crystallised after the toumaline (schorl) which is usually the case in old pegmatites. The schorl crystals in this pegmatite are also bent or curved slightly, which may be because the host granite rock was still moving (emplacement) when (or just after) the pegmatite was formed.
