Troilite (/ ˈ t r ɔɪ l aɪ t /) is a rare iron sulfide mineral with the simple formula of FeS. It is the iron-rich endmember of the pyrrhotite group. Pyrrhotite has the formula Fe (1-x) S (x = 0 to 0.2) which is iron deficient.

Named after Domenico Troili (11 April 1722, Macerata, Marche, Italy – 14 February 1793, Macerata, Marche, Italy) who first noted the mineral in a meteorite that fell in 1766 at Albareto, Modena (Italy). Troilite is the only Italian mineral whose type …

Troilite is a rare iron sulfide mineral and a member of the pyrrhotite group. Although it can be found on Earth, it is more abundant in meteorites. Domenico Troili collected and studied the samples of the mineral when a meteorite fall was observed in 1766 at Albareto, Italy.

Troilite is defined as a chemical compound with the composition FeS, commonly found in serpentinites, basalts, and meteorites. It is characterized by its light brown reflection color and strong anisotropy.

2003年3月30日 · The "troilite" veins consist of a heterogeneous mixture of troilite, low-temp pyrrhotite and pentlandite, all of which can be distinguished in polished section. The Handbook of Mineralogy lists troilite as a distinct species.
