Show Troilite Photos (12)
Formula:
FeS
System:HexagonalColour:Gray brown, bronze brown ...
Hardness:3½ - 4
Name:Named after Domenico Troili who first noted the mineral in a meteorite that fell in 1766 at Albareto, Modena (Italy).


Pyrrhotite Group.

Unlike Pyrrhotite (qv), Troilite has no vacancies in its atomic structure, and because of this it is non-magnetic. It is considered a grandfathered species by IMA CNMMN.

Classification of Troilite

IMA status:Valid - first described prior to 1959 (pre-IMA) - "Grandfathered" 1833
Explanation of status:It appears to be a polytype of pyrrhotite under the current IMA definition. It is considered a grandfathered species by IMA CNMMN, but, in fact, troilite might be pyrrhotite-2H at T < 122°C.
