11. Subsidence produces narrow ocean strips
Some 199-145 million years ago – the Jurassic era
The Tethys Ocean enlarged and the Dolomite region sunk into the abyss. The region contained two submerged plateaux (the Trento and Friuli platforms) where the sea was less deep, separated by two narrow strips of deep ocean, the Belluno and Lombardy basins, which were over 1000 metres deep.
