N2 - The topic of the field trip is the Mesozoic geodynamicevolution in the Western Tethys realm well recorded indeep-water settings, especially in the radiolarian-bearingsedimentary rocks and radiolarites in the Eastern Alps(Northern Calcareous Alps). The well preserved Mesozoicsedimentary successions deposited in the Northern CalcareousAlps reflect two different Wilson cycles with its mountainbuilding processes:Evolution of the Neo-Tethys Ocean to the south/southeast:The Middle Triassic oceanic break-up (Late Anisian)was followed by the Middle Triassic to Middle Jurassic passivemargin evolution and later by Middle to early Late Jurassicthrusting related to ophiolite obduction and subsequentlatest Jurassic to Early Cretaceous mountain uplift ofthe Neo-Tethys orogen to the south of the todays NorthernCalcareous Alps.Evolution of the Alpine Atlantic Ocean (named PenninicOcean in the Eastern Alps) to the north/northwest:The Late Early to Middle Jurassic oceanic break-up was followedby the Middle Jurassic to Late Cretaceous passivemargin evolution and Late Cretaceous to Palaeogene subductionof the Penninic realm, Palaeogene collision and subsequentNeogene mountain uplift with its gravitational collapse(Lateral Tectonic Extrusion) of the Alpine orogen s.str.For another orogenesis in the “Mid-Cretaceous” (Aptian-Cenomanian), i.e. between these two well recognizable
