Sr was used as a proxy indicating authigenic formation of aragonite in marine sediments. Distribution of Mo, Tl, U and Cd indicate changes in redox conditions in core sediments. Mo, Tl, U and Cd are associated early formed nanostructured authigenic framboidal pyrite. Concentration of Zn, Cu, Pb, Sn and Bi in core sediments indicates a low level of pollution.
