About Piromorfita
Pyromorphite is a lead phosphate of the mimetite–vanadinite group, common in the oxidised zones of lead deposits. Specimens from the San Andrés mine are known for their intense green colour and for having produced some of the best crystals of the species in Spain.
About the locality
The San Andrés mine, in Espiel (Córdoba), is one of the emblematic workings of the Sierra Albarrana district. In the 1980s and 1990s its galleries yielded exceptional pyromorphite specimens, especially from the geode known as "El Tarta".
