Abstract
A new occurrence of tennantite-(Hg) was recently confirmed at the Vyšný Klátov ore occurrence, Spišsko-gemerské rudohorie Mts., Košice-okolie Co., Košice Region, Slovakia. Tennantite-(Hg) occurs as lead-gray to black grains and aggregates up to 1 cm in size, associated with cinnabar, chalcopyrite, pyrite and hematite. Reflectance data of tennantite-(Hg) are given in this paper. The refined unit-cell parameters of tennantite-(Hg) from the Vyšný Klátov (for the cubic space group I-43m) are: a 22.523(7) Å and V 3105.4(1) Å3. Empirical chemical formulae of the two studied samples of tennantite-(Hg) from the Vyšný Klátov ore occurrence, recalculated on the basis of ΣMe = 16 apfu are: (Cu5.97Ag0.03)Σ6.00[Cu3.99(Hg1.95Fe0.10)Σ2.05](As3.57Sb0.39)Σ3.96S13.21 (sample VK1, n = 21) and (Cu5.99Ag0.01)Σ6.00[Cu4.05(Hg1.91Fe0.08)Σ1.99] (As3.79Sb0.15)Σ3.94S13.26 (sample VK3, n = 29).
