Matematica e Geoscienze, Trieste, Italy 2 OGS, Borgo Grotta Gigante-Sgonico, Trieste, Italy Introduction. In this study we interpret deep penetration multichannel seismic profiles (Fig. 1) to analyze the Messinian Salinity Crisis (MSC) markers in the different domains of the Mediterranean basins. The MSC represents a huge succession of events that modified the entire Mediterranean region in a relative short period of time (Hsü et al. , 1973); it produced a thick deposition of evaporate lithologies in the deep basins and an erosional unconformity on the marginal and onshore domains. This study is based on the analysis of both old and new seismic profiles in order to correlate the different seismic evidences of the MSC markers across the several different basins of the Mediterranean Sea. Seismic dataset. We used multichannel MS lines, sponsored by National Council of Research (CNR) and acquired and processed by OGS in 1972; deep crustal MCS profiles of the Italian Deep Crustal Exploration Project (CROP) (Scrocca et al. , 2003; Finetti, 2005), Fig. 1 - Map of the Mediterranean Sea with the position of the MS and CROP profiles. The deep basins are highlighted with blue color, the shallow basins with green color. 56 GNGTS 2013 S essione 3.1
