The interplay of carbonate systems and volcanics: Cues from the 3D model of the Middle Triassic Sciliar/Schlern platform (Dolomites, Southern Alps)

In the Dolomites (Southern Alps), the original stratigraphic relationships and depositional geometries of Middle Triassic carbonate systems are exceptionally preserved and exposed, and well-constrained in a high-resolution sequence stratigraphic and bio-chronostratigraphic framework. During the late Ladinian, the region experienced a strong tectono-magmatic event, leading to local uplifts and sinks, partial collapses of carbonate edifices and large submarine landslides, as well as the emplacement of thick volcanic and volcanoclastic deposits. The relationships between carbonate and magmatic bodies can be observed in detail in the area between the Sciliar/Schlern mountain group and the Alpe di Siusi/Seiser Alm.
