    Pyrite seldom forms in fresh-water environments. The formation of pyrite crystals depends mainly on the iron content of the sediment. The process of pyrite formation in sediments results from the action of bacteria, which reduce sulphate ions dissolved in the pore water to sulphide. If there is iron present, iron sulphide crystals begin to grow.
