Named in 1847 by Ours Pierre Armand Petit Dufrenoy from Greek “pyrrhos”, flame-coloured. Pyrrhotite has some unusual characteristics. First, it has an unusual formula. The amount of sulfur does vary by roughly 20% or 50 to 55 atoms of sulfur per 50 atoms of iron. Or is it the iron that varies? Really the same difference. Thus the unusual formula of Fe1-xS. Secondly, it has two symmetries.
