Summary: Analyses are presented of Pliocene sapropels from ODP Leg 160 borehole sites in the E Mediterranean. These sapropels contain high trace element contents, and fossil isorenieratene formed by photosynthetic green sulphur bacteria, suggesting that euxenic (sulphidic) and anoxic conditions prevailed in the photic zone of the Mediterranean water column. The S isotope composition of pyrite is consistent with Fe sulphide formation in the water column. Basin-wide water-column euxinic conditions occurred widely during Pliocene sapropel formation in this area.
