S34/S32 measurements and trace element analyses were performed on sediment from selected cores from the Red Sea geothermal deposit, the overlying brine and interstitial water.

The data show that δS34 falls into four general ranges: (1) >25 per mill, (2) +23 to +15 per mill, (3) +12 to +2 per mill, (4) <−25 per mill. Sulfate in the brine appears to have been derived from marine evaporites, whereas sulfide originates from two sources. In the Atlantis II Deep, it is derived from a hydrothermal process and introduced with the brine. In the other areas, biological sulfate reduction produces sulfide which precipitates metals from the brine originating in the Atlantis II Deep.
