Analcime with Rhodochrosite, Natrolite

specimen number:
2063212

location:
Poudrette Quarry, Mt. St. Hilaire, Quebec, Canada

description:
A cluster of colorless semi lustrous sharply formed analcime crystals, the prominent one measuring 1.5 cm across. Needlelike crystals of natrolite are present as well as small rosettes of brownish red rhodochrosite. In good condition.

The Poudrette Quarry is situated within the Cretaceous-aged Mont Saint-Hilaire alkaline intrusive complex in Quebec, Canada, formed by rare magma intrusions that concentrated high levels of incompatible elements. Operating primarily as a commercial stone quarry, it became world-famous among mineralogists and collectors due to its complex pegmatite pockets and xenoliths, which have yielded hundreds of unique and rare mineral species found nowhere else on Earth. Intensive commercial quarrying operations over the decades exposed these rich cavity systems, allowing researchers and hobbyists to salvage an extraordinary diversity of pristine specimens before active extraction wound down.
