specimen number:
2354263

location:
Francon Quarry, Montreal, Quebec, Canada

description:
Pale yellowish crystals of weloganite measuring to 0.8 cm in size on matrix with white botryoidal crystallized dresserite.

The Francon Quarry in Montreal, Canada, operated as a commercial limestone quarry that exposed a unique alkaline carbonatite sill, making it a world-renowned mineralogical site for rare species. During its active years of industrial excavation and later collecting periods before its closure, mineral enthusiasts and researchers recovered numerous unusual minerals from its vugs and cavities. Among its most famous discoveries is weloganite, a rare complex carbonate mineral first found here in 1967 and named after the first director of the Geological Survey of Canada. Weloganite is treasured by collectors for its distinctive pseudohexagonal, striated, lemon-yellow or amber crystals that formed within the carbonatite environment.
