Academic Project: Messinian Salinity Crisis, multi-proxy biostratigraphy, paleoenvironmental and paleogeographic reconstructions.

The impact of the Messinian Salinity Crisis is demonstrated in the area of the Dardanelles Strait using the calcareous nannoplankton biostratigraphy. The strait is superimposed, for its eastern part, on a Messinian fluvial valley. Extensive field investigations and analyses of the nannoplankton show that the Messinian Erosional Surface is overlain by Zanclean Gilbert-type fan deltas. In interfluvial locations, the Messinian Discontinuity is marked by rubefacted clays overlying a coastal lignite, and overlain by Zanclean marine sediments. The same approach has been extended throughout around the Marmara Sea and several sites located along its southern shoreline have provided well-preserved evidence of Messinian fluvial erosion followed by the Zanclean marine transgression. Several sets of seismic profiles acquired in different regions of the Marmara Sea with different degree of penetration and resolution suggest that the Messinian fluvial erosion affected the base of all the main sub-basins, implying that the bulk of the subsidence and sedimentation processes in the tectonically controlled Sea of Marmara pull-apart basin have started after the Messinian Salinity Crisis.
