The glittering golden mineral pyrite, an iron sulfide (FeS 2 ), is known to most people as fool's gold, something that promises great value but is intrinsically worthless. But pyrite is, has been, and will be important to you and the rest of humankind: It is the mineral that made the modern world. Ad Right.

To investigate the mechanisms involved in iron isotope fractionation during SO 4-AOM, we analyzed the isotopic composition of authigenic pyrite from two seafloor sites (HS148 and HS217) in the Shenhu gas hydrate area, South China Sea. The δ 56 Fe values of pyrite were found to vary from − 0.349‰ to + 0.267‰ in core HS148, and from …

A portion of H 2 S and pyrite is either aerobically or anaerobically oxidized (e.g., iron oxides and manganese oxides; Thamdrup et al., 1993; Lichtschlag et al., 2013) to sulfate, and the rest of the pyrite is buried and preserved in the sediment (Berner, 1970, 1984). Therefore, the pyrite in abundance appear in the sediments is an indicator of ...

Pyrite is a ubiquitous iron sulfide mineral that is oxidized by trace oxygen. The mineral has been largely absent from global sediments since the rise in oxygen concentration in Earth's early atmosphere. We analyzed weathering in shale, the most common rock exposed at Earth's surface, with chemical and microscopic analysis.

Iron can thus be exchanged between pyrite and wall rock under high fluid/rock alteration conditions; i.e., the system is open for Fe. In contrast, vein (L-type) pyrite is hosted in quartz veins. After crystallization, pyrite becomes isolated from flow of hydrothermal fluid by quartz, precluding isotopic exchange (closed system).
