Iron sulfide or Iron sulphide can refer to range of chemical compounds composed of iron and sulfur.
By increasing order of stability:
Iron(II) sulfide, FeS
Greigite, Fe3S4 (cubic)
Pyrrhotite, Fe1−xS (where x = 0 to 0.2) (monoclinic or hexagonal)
Troilite, FeS, the endmember of pyrrhotite (hexagonal)
Mackinawite, Fe1+xS (where x = 0 to 0.

The mineral pyrite (ˈpaɪraɪt), or iron pyrite, also known as fool's gold, is an iron sulfide with the chemical formula FeS2 (iron (II) disulfide). Pyrite is the most abundant sulfide mineral. Pyrite's metallic luster and pale brass-yellow hue give it a superficial resemblance to gold, hence the well-known nickname of fool's gold. The color has also led to the nicknames brass, brazzle, and brazil, primarily used to refer to pyrite found in coal.
Electron transfer reactions are central to the transformation of energy in the environment and play an important role in biogeochemical element cycling. In soils, one of the main drivers of carbon cycling is the activity of organisms that utilize the energ ...
Valorisation of locally available clays for producing blended cements is crucial for a widespread adoption of sustainable binders incorporating these materials. In some places, clays can be intermixed with small amounts of iron sulfides, which could eventu ...

Uranium (U) in situ bioremediation has been investigated as a cost-effective strategy to tackle U contamination in the subsurface. While uraninite was believed to be the only product of bioreduction, numerous studies have revealed that noncrystalline U(IV) ...
