Weloganite and minor Pyrite Francon Quarry, Montreal, Quebec, Canada
The Francon quarry in Canada is well known for some of the nicest weloganite crystals ever found. In fact, it is the type locality for these crystals, which contain both strontium and zirconium. This specimen features a 1.1 cm crystal nicely perched inside a vug and dusted with minor crystals of pyrite. It is well terminated, and I really like the growth patterns on the edge of the crystals. There was apparently a second crystal growing outward from beneath the first which cleaved away during collecting. This is not noticeable except with close examination (I needed a hand lens to see), but mention it for completeness. A very nice an aesthetic specimen. These pieces are no longer being found as they once were: the quarry has been inactive since 1981.
