Variable and negative iron isotope values in pyrites older than about 2.3 Ga suggest that an iron-rich global ocean was strongly affected by the deposition of iron oxides. Between 2.3 and 1.8 Ga, positive iron isotope values of pyrite likely reflect an increase in the precipitation of iron sulfides relative to iron oxides in a redox stratified ocean.

2008/11/21Abstract. Iron pyrites are waste products from mining operations and are also mined products. They have been used with varying success to supply Fe to plants, to supply S to plants, and to ameliorate sodic soils when oxidized to acid which forms gypsum in calcareous soil. Several forms of pyrite exist depending upon origin and crystallinity.
