    Description

    Pyrite after Pyrrhotite
    Santa Eulalia Dist.
    Mun., de Aquiles Serdan
    Chihuahua, Mexico
    4.49 x 2.99 x 2.99 inches (11.40 x 7.60 x 7.60 cm)


    The Mexican mining camp of Santa Eulalia has produced many fine specimens over the years. A change in the fluid chemistry in the ore body can result in Pyrrhotite altering to a chemically similar material like Pyrite, while still retaining the overall form of the original Pyrrhotite. Here, portions of the Pyrrhotite have dissolved away, leaving a partially hollow 'cast' of the original. Associated with the Pyrite cast are numerous needles of Quartz and a bit of black Sphalerite which are all in excellent condition.
