• How Is Pyrite Formed? | Reference

    Pyrite forms due to a chemical process initially caused by the decomposition of organic matter in bacterial sulfate reduction The bacterial sulfate reduction produces an inorganic anion known as bisulfide, which reacts with iron minerals to form iron sulfides, the most common of which is pyrite
