Summary:Tellurantimony has been recorded for the first time in Europe. It occurs in the epithermal precious metal deposits of W Romania: Nagyag (now Sacarimb), Stanija, and Magura-Hondol. The optical properties, chemical composition, and mineral association of Sb2Te3 are described. Significant contents of Pb, Au, Ag, and As have been noted, and these seem to be related to the specific occurrence and association. The mutual relationships of incorporation and substitution between minerals which constitute the assemblages suggest the following order of deposition for this mineralization at Stanija: pyrite + chalcopyrite - altaite + frohbergite + arsenopyrite + stutzite + tellurantimony + sylvanite - native tellurium ± tellurantimony; mineral assemblages at Sacarimb: stutzite + tellurantimony + stibnite + petzite + 'hessite + sylvanite' (a decomposition product of the Au-rich Γ-phase) ± pyrite; at Magura-Hondul: krennerite + sylvanite + montbrayite + tellurantimony + petzite + altaite. Further minerals observed are stibnite, petzite, hessite, krennerite and montbrayite. The mineral assemblages probably formed under conditions of high fTe2 and mean to low fS2. [H.E.]
