| Summary: | <div>At the end of Pliensbachian or during the Toarcian, several carbonate</div><div>platforms were individualised by extensional tectonics in southern</div><div>Tethys, of which the Adriatic Carbonate Platform is one. As a unique</div><div>and isolated shallow marine depositional system it existed until the</div><div>end of the Cretaceous. In the Late Lias, the platform margins and</div><div>slopes were formed by the individualisation processes. Due to the</div><div>presence of younger sedimentary cover and tectonic disruption from</div><div>the Early Jurassic until the present, only small parts of the north-eastern</div><div>margin and its slope are exposed at the surface.</div><div>During the entire “life-span” of the platform, its NE margin and</div><div>slope retained more or less the same palaeogeographic position – from</div><div>western to south-eastern Slovenia, through the central part of Croatia,</div><div>western and central Bosnia, northern Herzegovina and Montenegro</div><div>all the way to northern Albania. The region between Žumberak in</div><div>Croatia and central Bosnia was the most dynamic part of the platform</div><div>margin during the Jurassic and Cretaceous. Shifts of the marginal and</div><div>slope facies were recorded in Žumberak, where the platform area was</div><div>progressively reduced during the period from the Lias to the Malm.</div><div>At the same time, the platform was extended in central Bosnia and</div><div>Montenegro. A more pronounced reduction of the platform in Cenomanian times marked the beginning of the process of disintegration.</div><div>The end of the Cretaceous was also the end of the “life” of the Adriatic</div><div>Carbonate Platform. It mostly became emergent, and the renewed</div><div>shallow marine carbonate depositional environments in the Eocene</div><div>were short-lived and lacked the previous platform characteristics, as</div><div>well as the regional distribution and integrity.</div> |
