JFD13AN5: Alain Martaud spent quite a long time in La Unión digging for minerals and took advantage of the time to obtain a good number of specimens from the area. All 'special', such as this Smithsonite and Galena pseudomorph that has replaced an older Pyrrhotite crystal, which in addition to being interesting (mineralogically speaking) has the great advantage that it makes the specimen stable, so it will not suffer the alteration that so often happens to pyrrhotites. In addition, a small group of the ubiquitous barytes from that area embellish the specimen.
