Pyrrhotite is unusual in that it maintains a variable iron content, as reflected in its odd chemical formula.The variability is formed by deficiencies of iron in its chemical structure, which is also responsible for its magnetic properties. Greater deficiency of iron is ...
Pyrrhotite is an iron sulfide mineral with the formula Fe (1-x) S (x = 0 to 0.2). It is a nonstoichiometric variant of FeS, the mineral known as troilite.Pyrrhotite is also called magnetic pyrite, because the color is similar to pyrite and it is weakly magnetic.The magnetism decreases as the iron content increases, and troilite is non-magnetic.

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.
Groups of laminar crystals of Pyrrhotite in rosettes. They are very aerial, of a considerable size and are on a rocky matrix. The crystals of Pyrrhotite, with recrystallized Pyrite on the surfaces of the pinacoidal faces, remain stable in spite of the long time that has passed since they were recovered, very probably due to the presence of the Pyrite.
