Sažetak
This is the first seismic analysis of Cenozoic clastic in the area of the Neretva River delta. The contemporary borders of the Adriatic Sea started to form after Messinian salinity crisis. It is why authors assumed that contemporary rivers mostly also existed in the last 5-6 Ma, i.e. in the Pliocene and Quaternary periods. Indirectly, authors supposed that analysed Cenozoic sediments belong to Pliocene and Quaternary periods. Moreover, the delta and prodelta progradation can be easily followed on presented seismic sections (Figures 3, 4, 5), especially at Figure 5 even to the Mesozoic basement, what is the second indirect prove that entire Cenozoic sequence is of Pliocene and Quaternary age, when is assumed activity of the palaeo Neretva River mouth. Also, the analogy with Pliocene and Quaternary sedimentation in the Po Depression is used. However, the possible lateral extension of analysed delta and prodelta sediments had been highly restricted with geomorphological units exposed inland in the past. It means that the thickness of clastics is significantly lower than in e.g. the Po or Venetto Depressions. Consequently, the formed anticlines have the very small potential structural closure, smaller than in the northern Adriatic in the sediments of the same age. To explore hydrocarbon potential of described sediments, it would be useful to perform additional seismic exploration and drill at least one well southern from the Hvar and Korčula Islands. Such results could probably show extension and thickness of possible prodelta sediments deposited in the glacial periods, in areas where the Mesozoic basement had been deeper.
