Simplified paleogeographic reconstruction of the future Alps-Dinarides junction area (view is from the east and the Bled Basin succession in the Pokljuka Nappe (highest thrust-unit of the eastern Southern Alps) is not included in the figure): In the Ladinian the entire area was subjected to differential subsidence and accompanied by volcanic activity. In the south (present day Dinarides), lateraly diverse sedimentary environments developed, including subaerially exposed ares, platforms, and small-scale basins. The greatest subsidence occurred in the central area (present day Tolmin Nappe of the Southern Alps); to the north (present day Krn and Slatna Nappes of the Southern Alps); however, carbonate platforms dominated. In the Carnian, the southern and northern areas were levelled, while the central area remained deep (see also Additional file 3), thus forming the largest and long-lived deep marine paleogeographic unit known as the Slovenian Basin, which pinched out towards the west
