抄録
Sulfide minerals from some of the Carboniferous to Permian Kieslager-type deposits in eastern Chugoku and western Kinki district have been studied isotopically. Notwithstanding the differences in the age and acidity of host volcanic rocks, the studied deposits show a remarkble uniformity in sulfur isotopes, all δ34S values falling in a narrow range from +0.6 to +2.9‰. This implies all the deposits studied have a common source of sulfur for sulfide minerals plausibly dominated by sulfur derived from a deep-seated origin. Barite samples from the Yanahara deposits are found to have δ34S values of +12.1 to +15.1‰, which suggests the coeval sea water sulfate was the principal source for the barite.
