Fluorapatite

This specimen features a lovely greenish-to-navy blue fluorapatite crystal with good translucency and a single pointed termination. It sits attractively partly exposed in its fleshy light pink calcite matrix.

This fluorapatite originates from a locality just near the small town of Perkins, Quebec, an obscure locality within the Grenville Province, renowned for its abundance of pegmatites. During the Grenvillian orogeny, these rocks experienced intense deformation and high-grade metamorphism, resulting in a predominance of calcitic marbles in the region. Metasomatic reaction zones formed at the contacts between calcitic marbles and silicate rocks, generating higher-than-usual concentrations of fluorapatite, making this specimen a good example from this geologically intriguing area.
