TELLURANTIMONY IN ROMANIA - FIRST OCCURRENCES IN EUROPE

Tellurantimony, Sb2Te3 has been recorded for the first time in Europe. It occurs in the epithermal precious metal deposits of western Romani a: Nagyag (now Sacaramb), Stanija, and Magura-Hondd. The optical prope rties, chemical composition, and mineral associations of the tellurant imony are described. Significant contents of Pb, Au, Ag, and As have b een noted, and these seem to be related to the specific occurrence and association. The tellurantimony-bearing assemblages probably formed u nder conditions of high f(Te2) and mean to low f(S2).
