The Polemi basin (S Cyprus) records a well exposed Messinian Salinity Crisis (MSC) evaporite succession divided into three lithostratigraphic units: Lower Gypsum, Intermediate Gypsum Breccia, and Upper Gypsum. Sulfate isotope compositions of the Lower Gypsum show values in range with MSC Lower Evaporites outcropping in other Mediterranean basins. However, the Intermediate Gypsum and the Upper Gypsum show an enrichment of ~5‰ in δ18O, with respect to the Lower Gypsum unit, as reported in MSC Upper Evaporites outcropping in Sicily and cored in DSDP-ODP sites. Similarly, 87Sr/86Sr ratios in the Lower Gypsum unit are also in range with MSC Lower Evaporites, while values in the Intermediated and Upper Gypsum units are coincident with those reported for MSC Upper Evaporites of Sicily and of foredeep sites. These geochemical values put into question the currently more accepted MSC chronostratigraphic model in which clastic (resedimented) gypsum is assigned as prior to the Upper Evaporites.
