Formula: Cu6(Cu4Zn2)Sb4Se13
Sulphosalt, hakite subgroup,
tetrahedrite group,
antimony- and selenium-
bearing mineral
Crystal System: Isometric
Environments
Hakite-(Zn) is a new mineral, approved in 2022 and to date (March 2024) reported only from the type locality.
Localities
At the type locality, the Mine dump, Uranium Mine No. 16, Háje, Příbram District, Central Bohemian Region, Czech
Republic, a new occurrence of hakite subgroup minerals was found to be
locally abundant and was identified in several samples with selenium
mineralisation. Three chemically distinct types of hakite were
distinguished: hakite-(Hg), hakite-(Zn) and
hakite-(Cd). Hakite-(Hg)
dominates among the samples studied.
The evolution of hydrothermal fluids, from which selenium mineralisation
formed, suggests a distinct enrichment in sulphur and depletion in
selenium over the time span of crystallisation.
