Abstract
This study shows delta(34)S values for the study of co-existing baryte and galena, respectively, are in the ranges of +6.9 to 8.0 parts per thousand and -6.0 to -9.8 parts per thousand. Such narrow ranges make biogenic sedimentary source for sulphur less likely and suggest magmat ic source. Sulphur isotope values indicate a hydrothermal system with a T of similar to 440 degrees C, pH 5+/-1 and Log fO(2) of -34 to -37.
