Abstract

Adriatic coast are still not completely resolved mostly due to the intensive and complicated regional and local neotectonics.We gathered current knowledge that generally presents the north Adriatic area as subsiding one, and proposed a reconstruction in new light of possible very slow (local) uplift (average rate of 0.1–0.25 mm/a for last 80 ka)which is supported bywell-dated submerged speleothemsand tectonic reconstruction. In addition, such a scenario supports also the formation of tidal notches that are common in the north Adriatic region, but not yet entirely understood. However, according to the latest Mediterranean data on sea level during the marine isotope stage (MIS) 5.1 being at +1 m 80 ka ago, we do not dismiss the possibility of subsidence which would have been 0.18–0.23 mm/a on average for the last 80 ka, but notch formation under such condition would not have been realistic. Apparently, the position of the north-eastern Adriatic coast on a convergence area requires extensive palaeoenvironmental studies, including structural, lithostratigraphical, palaeontological, archaeological and radiometric data and application of isostatic modelling.
