Fig. 1

Jurassic palaeogeographic domains projected over the present day geography. The original spaces are shortened in the north by Alpine and in the east by Dinaride structures. The red faults are Jurassic rift structures recognized in the field. The studied stratigraphic sections are aligned along the two perpendicular tracks and are spatially represented in Figs. 4 and Fig. 5, respectively. The four sites chosen for the subsidence analysis of Fig. 6 are Cesarolo 1 well, and the composite sections Istria 2, Gorsky Kotar 3 and Karlovac 4. Open dots are HC exploration wells, locally used for reconstructing the geological features in the subsurface
