Fluororichterite

specimen number:
2354191

location:
Wilberforce, Haliburton Co., Ontario, Canada

description:
Classic Canadian specimen, a loose double terminated sharply formed crystal of fluoro-richterite. This is in good condition all around.

Located within the Grenville Province of the Canadian Shield, the Wilberforce area in Haliburton County, Ontario, is celebrated for its complex pegmatites, marble-hosted uranium occurrences, and diverse alkaline rock assemblages formed during intense Proterozoic metamorphism. Mining and prospecting activity in the region peaked during the early to mid-twentieth century, driven by a search for radioactive minerals, industrial fluorite, and rare-earth pegmatite deposits. Over the decades, the area gained international fame among recreational rockhounds and mineral collectors for its exceptional pocket specimens. Among the notable silicate minerals found in this environment is fluoro-richterite, a rare chain-silicate amphibole that occurs as prismatic crystals embedded within white calcite and related metamorphic matrices, securing the region's status as a classic Canadian collecting destination.
