    AnnotationNumerous occurrences and deposits of Sb-Au mineralization containing gold-bearing sulphides are described from an area of the Tatric Unit in Western Carpathians e.g.: Pezinok, Dúbrava, Jasenie, Nižná Boca, Vyšná Boca etc. It was shown, that arsenopyrite is the main sulphide mineral incorporating invisible gold in its crystal structure. Concentrations of invisible gold in pyrite are not as high as in arsenopyrite. Only if arsenic is present in the pyrite in amounts greater than 0.2 wt %, there is significant incorporation of Au in its crystal structure. Gold content in these sulphides ranges from zero up to n.100 ppm. The fine-grained types contain higher Au concentrations, by as much as an order of magnitude. This work has demonstrated that Au coprecipitated together with Fe, As and S during the arsenopyrite and pyrite crystallization and was incorporated in sulphide mineral crystals both as native gold and chemically bound gold. Although As and Au contents in arsenian pyrites and arsenopyrites vary from sample to sample, there is a positive correlation between Au and As. The covariance in As and Au indicate that they were transported by the same solution and that the same geochemical processes led to their removal from solution. Au is predominantly concentrated within As-rich zones of gold-bearing sulphides. Gold-bearing arsenopyrite and pyrite precipitated at the onset of the paragenetic sequence. They crystallized within a broad temperature range: 319 to 450 °C
