About Tennantite-(Fe)
Formula:
Cu6(Cu4Fe2+2)As4S12S
Crystal System:
Isometric
Member of:
Name:
Named during a reclassification of the tetrahedrite group (IMA proposal 18-K, detailed in Biagioni et al. (2020)). The suffix indicates the dominant M(1)C constituent (the charge compensating constituent).
Type Locality:
Added due to the acceptance of the IMA 18-K proposal.
More common than tennantite-(Zn) with which it forms a complete solid-solution series.
The As analogue of tetrahedrite-(Fe).
