About Tetrahedrite GroupHide

Formula:
M2(A6)M1(D4C2)X3(E4)S1(Y12)S2(Z)
A = Cu+, Ag+, ☐;
D = Cu+, Ag+;
C = Zn2+, Fe2+, Hg2+, Cd2+, Mn2+, Cu2+, Cu+, Fe3+;
E = Sb3+, As3+, Bi3+, Te4+;
Y = S2-, Se2-;
Z = S2-, Se2-, ☐.
The tetrahedrite group is divided into five different series on the basis of the A, D, E, and Y constituents, i.e. the tetrahedrite series, tennantite series, freibergite series, hakite series and giraudite series. The nature of the dominant C constituent is made explicit using a hyphenated suffix between parentheses.
The new nomenclature and classification of the tetrahedrite group was approved by the IMA in 2019 (proposal 18-K).

According to the the CNMNC Newsletter No. 49, eleven minerals belonging to the tetrahedrite group can be considered as valid species: argentotennantite-(Zn), argentotetrahedrite-(Fe), kenoargentotetrahedrite-(Fe), giraudite-(Zn), goldfieldite, hakite-(Hg), rozhdestvenskayaite-(Zn), tennantite-(Fe), tennantite-(Zn), tetrahedrite-(Fe), and tetrahedrite-(Zn).

A Bi-dominant composition, which probably represents a new species, has been reported by Gołębiowska et al. (2012).

Note: the D site is named as B in the IMA Proposal 18-K, here as D to avoid confusion with Boron. (The E site is named as D in the IMA Proposal 18-K)
