Arsenopyrite Group. For possible Ni-analogue see Unnamed (Ni,Fe,Co)AsS; see also Unnamed (Ni Arsenide Sulphide).Arsenopyrite is closely related to alloclasite, but is not an exact analogue, because of different As-S and S-As ordering. Arsenopyrite may contain up to about 9 wt.% Co; with higher Co contents, glaucodot will appear as a separate phase (Gammon, 1966).

Arsenopyrite - Wikipedia

Arsenopyrite is an iron arsenic sulfide (FeAsS). It is a hard (Mohs 5.5-6) metallic, opaque, steel grey to silver white mineral with a relatively high specific gravity of 6.1.When dissolved in nitric acid, it releases elemental sulfur.When arsenopyrite is heated, it produces poisonous sulfur and arsenic fumes which can be fatal if inhaled in large quantities.
