Crustal Section Across the North Adria Plate From Italian (Pesaro) to Croatian (Kvarner) Shorelines

Based on interpretation of seismic data calibrated by wells, a new regional interpretation across upper crust beneath the Northern Adriatic Sea from Pesaro (Italian shoreline) to Kvarner Gulf (Croatian shoreline) is proposed (Fig. 1). Starting from the calibration point, seismic-stratigraphic facies was classified for the lithological units. The most recognizable reflectors, not always clear, are typical: the base of Plio-Quaternary (PQ) generally coincides with the Messinian erosional surface (MES), often reaching the Paleogene- Neogene sequences and the top of the Mesozoic carbonate succession. The base of the carbonates is also visible in many profiles, covering the thick Permo-Triassic (PT) clastic sequence. From the west to the east, the profile shows several main geological structures characterizing the Adriatic Sea: i) the Northern Apennines frontal thrusts ; ii) the corresponding foredeep basin filled by a thick PQ sequence ; iii) the “build- up”-like structure along the margin between the Liassic/ Cenozoic Adriatic pelagic sequence (on the west) and the Adriatic Carbonate Platform (on the east) ; iv) the frontal thrusts of the External Dinarides, represented by gentle anticlines of the carbonate platform succession that are probably detached from the basement. The steep westward tilting of the common Adriatic fore- land gently affects also the Adriatic Carbonate Platform. It is evident by Pliocene stratal terminations, onlapping the main Messinian unconformity, or the top of an Early Pliocene sedimentary unit. Moreover, erosional canyons, filled with several generations of various clinoform packages are very common in the Kvarner region. These canyons are probably incised during Messinian times, due to erosion, but infill patterns are also suggesting their relations with the large scale strike-slip faulting. Recent strike-slip related transpresssional and transtensional features are also evident in the Kvarner area. This coast to coast type of regional study allows revelation of differing tectonic structures and stratigraphic relations across the Adriatic Sea, which typically cannot be reconstructed on a small, local scale. It shows that the pre- and syn-orogenic structures were sometimes reactivated during the post-orogenic phase, probably associated with large scale motions of Adria plate indicating still active neotectonic movements.
