Sulphide body

A sulphide body is a massive sulphur deposit in the form of an interlayered accumulation in volcanic or volcano-sedimentary rocks. Composed mainly of iron sulphides (pyrite, marcasite, pyrrhotite), they contain variable amounts of base metal sulphides (Cu, Pb, Zn); some can be rich in gold. One of the most famous examples are the deposits in the southern Iberian pyritic province, in Spain and Portugal.
