The representative successions of the Bled, Tolmin and Bovec basins, and the Julian High are described and illustrated. The stratigraphy of these locally recognized basins is correlated regionally and discussed in the larger framework of the evolution of the Adriatic continental margin. The paper is written as a field-trip guide for a post-conference excursion of the 29th IAS Meeting.

COBISS.SI-ID: 2076245Preliminary results on sedimentology and biostratigraphy of the Bled Basin were presented at the 29th IAS Meeting in Schladming. The end Triassic to Early Cretaceous tectonostratigraphic history of this basin was divided into the following stages: Late Triassic to Early Jurassic extension culminating in the Pliensbachian subsidence pulse; Middle Jurassic commencement of convergent regime and a renewed subsidence in the Bajocian due to tectonic down-warping; Early Cretaceous progressive closure of the Neotethys and evolution of the Bled Basin into a typical foreland basin.
B.03 Paper at an international scientific conference
COBISS.SI-ID: 34773805At the 20th Congress of CBGA (Carpathian Balkan Geological Association) stratigraphic successions of the Julian High and the Bled Basin were presented and correlated with the successions of the Southern Alps and Northern Calcareous Alps. We prepared a compilation of regional paleogeographic distribution of two types of intrabasinal highs: Trento (pelagic plateaus on rifted margin) and Plassen (carbonate platforms on top of Upper Jurassic nappe stacks). We emphasized the importance of the Julian Alps for paleogeographic reconstructions because the boundary between the Julian High (Trento type plateau) and the Bled Basin (including limestone breccias sourced from a Plassen type carbonate platform) represented the western limit of contractional regime in the Early Cretaceous.

COBISS.SI-ID: 2313813A talk at the 4th Slovenian Geological Congress in Ankran presented a synthesis of the stratigraphic evolution of the Cretaceous-Paleogene foreland basin in western Slovenia. The studied sequence included three units, reflecting drowning of the carbonate platform, development of a depocenter of a maximum depth over the drowned platform, and deposition of turbidites from an evolving orogen during the underfiled stage of the basin, illustrated by spatial and temporal geometry of the major stratigraphic discontinuities.

COBISS.SI-ID: 37679149Triassic sedimentary rocks of Mt. Prisojnik are described. The geological history of the area (formation of half-grabens and neptunian dykes, differential subsidence of different blocks and volcanic activity) is explained in comparison with the recently active East African Rift. The paper is an important contribution to the promotion of geology and Slovenian geological heritage.
