About ArsenopyriteHide

Formula:
FeAsS
Colour:
Silver-white to steel-gray, may have a slight yellow appearance
Lustre:
Metallic, Sub-Metallic
Hardness:
5½ - 6
Specific Gravity:
6.07
Crystal System:
Monoclinic
Name:
Named in 1847 by Ernst Friedrich Glocker for its composition, a contraction of the antiquated term "arsenical pyrite." Arsenopyrite was known much before 1847 and arsenopyrite, as a name, may be taken as a simple translation of "arsenkies".
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.

Other InformationHide

Notes:
Decomposed by nitric acid with separation of arsenous acid and sulphur.

In a closed tube, at first gives a red sublimate of arsenic sulfide, then a black lustrous sublimate of metallic arsenic. In an open tube, gives sulphurous fumes and a white sublimate of arsenous acid.
Health Risks:
No information on health risks for this material has been entered into the database. You should always treat mineral specimens with care.

    Locality ListHide

    - This locality has map coordinates listed. - This locality has estimated coordinates. ⓘ - Click for references and further information on this occurrence. ? - Indicates mineral may be doubtful at this locality. - Good crystals or important locality for species. - World class for species or very significant. (TL) - Type Locality for a valid mineral species. (FRL) - First Recorded Locality for everything else (eg varieties). Struck out - Mineral was erroneously reported from this locality. Faded * - Never found at this locality but inferred to have existed at some point in the past (e.g. from pseudomorphs).

    All localities listed without proper references should be considered as questionable.
