Sulfur isotope compositions from different type of deposits in the Buchim-Damjan-Borov Dol ore district, eastern Macedonia

For, at least in part, determination of the origin of metals and sulfur in the ore district Buchim-Damjan-Borov Dol we made a series of complex research and analysis of the light isotope (32S), heavy isotope (34S), and their isotopic ratio (d34S). In three deposits of the Buchim-Damjan-Borov ore district were sampled mostly pyrites from the hydrothermal range 250–350ºC (from each ore body mineral parageneses). For the porphyry copper ore deposits Buchim isotopic ratio values ranged from 0 to +2.09‰ averaging +0.982‰, while the Borov Dol values have shown wider range starting from –7.25 up to +0.72‰ averaging –2.238‰, due to enrichment with lighter sulfur isotope. Sulfur isotopic ratios for the Damjan Fe-skarn deposit have shown relative enrichment with heavy sulfur isotope resulting in value range of +1.75 up to +8.68‰ averaging +5.248‰
