Fluorapatito is a mineral with formula Ca₅(PO₄)₃F, in the Fosfatos group. This specimen comes from Panasqueira, Aldeia de S. Francisco, Covilhã, Castelo Branco, Portugal.
Description
Green cubic (hexagonal) crystals formation without matrix. Fluorescent.
About Fluorapatito
It is not very common but recurrent at the deposit, valued for its thick, well-defined green crystals, a compact, flattened habit that is often cubic or pseudo-isometric, and its fluorescence. Very different from other Iberian apatites, which are more prismatic.
About the locality
A world reference for its hydrothermal veins and an exceptionally diverse paragenesis. In cavities and late-stage zones associated with carbonates, fluorapatites form occasionally and continue to appear sporadically in modern material.
