This excursion explores the Triassic–Jurassic depositional history of the Dinarides, with a particular emphasis on the relationship between shallow-water carbonate production and coeval deep-water sedimentary successions. A central objective is to understand the Mesozoic—primarily Triassic to Jurassic—geodynamic evolution of the Western Tethys Realm, in which the Dinarides represent a key orogenic system.

 The field trip will focus on the deep-water sedimentary rocks during the Triassic-Jurassic geodynamic history in different basins: rift-basins, shelf areas, oceanic domains, trench-like basins, foreland basins.

Special focus will be the so-called Lim zone in the Triassic (Lim deep-water intra-plattform basin) with the Zlatar and Cehotina deep-water subbasins between the Drina-Ivanjica unit (shallow-water Golija zone) and the shallow-water Durmitor zone with the shallow-water Mihajlovici ridge in the central part, all of them interpreted as Ladinian to Rhaetian shallow-water platforms (Wetterstein and Dachstein).

We will visit:

– Middle Triassic to Middle Jurassic passive margin evolution: all depositional realms from the continental slope to the the central shelf.

-The Middle Triassic continental break-up: Anisian demise of shallow-water carbonate production, horst-and-graben formation, and deposition of deep-marine sediments elsewhere.

-Restart of shallow-water carbonate production in the Middle and Late Triassic: the sedimentary sequences in the deep-water depositional realm as mirror of platform progradation (Sequence stratigraphy, highstand shedding, carbonate production potential).

-Reasons for the demise of the Triassic shallow-water platforms and the expression of these events in deep-water settings.

-Condensed Early-Middle Jurassic deep-water sedimentary rocks.

-Active continental margin evolution: Middle to Late Jurassic radiolaritic/argillaceous trench-like basin formation and nappe stacking in front of obducting ophiolites, large-scale mass movements. Mélange formation. The whole story is visible in one of the most beautiful areas of the Balkan Peninsula, the area between the Inner and Outer Dinarides in western Serbia and northern Montenegro. The field trip will provide beside geological highlights also special insights in culture and undisturbed nature in an area with increasing tourism.
