Cretaceous post-ophiolithic sedimentation and Gosau-type basins
Conveners: Michael Wagreich
Cretaceous cover of ophiolithes and basin forming processes during the Cretaceous remain an unsolved puzzle in the Alpine-Carpathian-Balkan area. The term Gosau was used loosely for transgressive Upper Cretaceous successions within an area from the Eastern Alps of Austria up to the Carpathians of Romania and to Serbia. Largely similar basin development points to a common evolution of the area after mid-Cretaceous tectonism followed by renewed marine transgressions and a deepening of the depositional areas. Some more similarities such as the occurrence of ophiolitic detritus including chrome spinel points to a common mechanism of basin formation related to Late Jurassic to Early Cretaceous ophiolite obduction and suturing in the Neotethys realm.
