Ag2S
Monoclinic
Acanthite, a silver sulfide mineral, was reported from Franklin by Hendricks (1960) and subsequently reported from there and Sterling Hill by Frondel (1972). Acanthite is dull black and sectile. Few specimens exist, and none have been studied in detail. Hendricks (1960) and the writer have found acanthite as a component of thin silver films associated with chalcocite and magnetite from Franklin. Energy- dispersive X-ray analysis showed the presence of major Ag and S. Some specimens may have been labeled argentite.
