Pyrochlore Supergroup (Formerly known as Betafite) & Zircon – Silver Crater Mine, Haliburton Township, Ontario, Canada

This striking specimen features a cluster of Betafite crystals accompanied by a well-formed Zircon, collected from the famed Silver Crater Mine in Cardiff, Ontario. The betafite shows the typical resinous luster and octahedral form, varying from brown to dark reddish-black, and contains significant uranium and rare earth elements. Intergrown with it is a sharply defined zircon crystal, adding contrast and complexity to the specimen. Together, they exemplify the unusual mineral associations found in the region’s carbonatite and syenite intrusions.

The Silver Crater Mine is a classic Canadian locality known for producing radioactive and rare-element minerals of exceptional quality. This combination piece not only makes for a visually dynamic display but also highlights the geochemical richness of Ontario's Grenville geological belt. Highly desirable for collectors of radioactive minerals or Canadian localities, this specimen is both scientifically intriguing and aesthetically compelling.
