Minerals formed in 30-km-deep, alpine-type fractures that cross-cut the foliation of the gneiss bedrock. Most famous for its Tessin habit and sceptered quartz crystals, plus assemblage of magnesite, almandine, pyrite, tourmaline, and free-standing kyanite crystals.
This is an operating quarry and collecting is not allowed without permission, which in recent years is rarely given.
