Panasqueiraite

A nice sample of Panasqueiraite, from the collection of José Miguel Sola Fernández.

Pinkish brown panasqueiraite (or possible triplite) with quartz. Specimen not analyzed. Collection and photo Rui Nunes, January 2005. Note: Panasqueiraíte is a monoclinic calcium-magnesium phosphate, a hydroxyl-bearing analog to isokite (Isaacs and Peacor, 1981). At Panasqueira, its type locality, it is found intergrown in massive, fine ...

Extremely rare. Panasqueraite occurs at only two locations, and these are in the same district. This crystalline, massive panasqueiraite is classic for its habit and tannish-flesh color. The luster is actually very good, and I am told this would be a very rich specimen. The remaining parts of the piece is gray quartz, bladed but incomplete ...

Panasqueiraite is a very rare calcium magnesium hydroxyl fluoro-phosphate that to the best of my knowledge has only been found at its namesake locality, the Panasqueira Mines in Portugal. The species has been approved since 1978, but still never seen in another world locality. Panasqueiraite has a distinctive muted pinkish-orange hue, so it's easy ...
