The Pyrite Group is a fairly large group composed of minerals with a similar structure and chemistry. It is named for its most common member, Pyrite. Only pyrite is common and only a few other members are recognized or readily available for collecting. The general formula for this group is AX2. Pyrite's formula for example is FeS2. The A can be either cobalt, copper, gold, iridium, iron, manganese, mercury, nickel, osmium, palladium, platinum, ruthenium or zinc. The X can be either antimony, arsenic, bismuth, selenium, sulfur and or tellurium.
