Decomposition decreased in the order orpiment, stibnite, realgar, and arsenopyrite. In the case of arsenopyrite the decomposition was slight even at pH 12. At pH 10 the only solutions showing high total sulphide sulphur content were those which had been in contact with orpiment; those from the realgar and stibnite tests showed only traces.

Arsenopyrite Group. 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). May be confused with the iron arsenide löllingite.
