Argentotetrahedrite-(Fe)

Argentotetrahedrite-(Fe) is an IMA-recognized mineral species in the sulfosalt class, with the chemical formula Ag₆(Cu₄Fe₂)Sb₄S₁₃.

It crystallizes in the cubic crystal system (space group I-43m). It is a member of the Tetrahedrite structural group.

Key properties: Mohs hardness 4.

IMA symbol Attr-Fe, IMA status: approved, named in 2016.

Found in hydrothermal veins and contact metamorphic deposits.

As the Sb-analogue of argentotennantite. The suffix, (Fe), indicates the dominant composition in the C structural site.
