Isotopic composition is determined for ore sulfur from seventeen Au-Ag, six W-Mo and one fluorite deposits in the southern Korean Peninsula. The age of ore formation ranges from pre-Cambrian to Creta ceous. Together with the data available in the literature, the following characteristics are recognized: 1) most 6345 values fall in the narrow range of +2 to +7%o, 2) no systematic variations are observed among the deposits of different geologic environments and with different workable metals, and
