RM2890   Huntite and aragonite

Turó de Montcada Quarry, Montcada i Reixac, Barcelona, Catalunya, Spain

Specimens of huntite from this classic Catalan locality are hard to see. Huntite occurs by filling cavities in a matrix of ampelitic shales. It is a carbonate of calcium and magnesium, powdery in appearance, snowy white in color. It is accompanied by small acicular crystals of very bright aragonite. Huntite was identified by XR diffraction in Montcada hill quarry in the late 1990s (Cendón et al. 1997; link).
