Localities

There are two co-type Localities, the Kremnica Au-Ag deposit, Kremnica, Žiar nad Hronom District, Banská Bystrica Region, Slovakia and the Lengenbach Quarry, Fäld, Binn, Goms, Valais, Switzerland.

At the Zvěstov deposit, Zvěstov, Benešov District, Central Bohemian Region, Czech Republic, argentotetrahedrite-(Zn) occurs as irregular aggregates, up to 0.2 mm in size, partly rimmed by kenoargentotetrahedrite-(Fe) (MM 86.2.319-330).

At the Kremnica Au-Ag deposit, Kremnica, Žiar nad Hronom District, Banská Bystrica Region, Slovakia (one of the type localities), arentotetrahedrite-(Zn) occurs as anhedral grains up to 0.1 mm in size, steel-grey in colour, with a metallic lustre, in association with kenoargentotennantite-(Fe) and tiny chalcopyrite grains in quartz gangue (MM 86.2.319-330).

At the Lengenbach Quarry, Fäld, Binn, Goms, Valais, Switzerland (one of the type localities), argentotetrahedrite-(Zn) was found as domains of tristetrahedral crystal of tetrahedrite-(Zn), up to 1 mm in size, associated with dolomite (MM 86.2.319-330).
