Fig. 11 in Pliensbachian, Early Jurassic radiolarians from Mount Rettenstein in the Northern Calcareous Alps, Austria

Fig. 11. Combined radiolarian and ammonite dating of Lower Jurassic deposits on Mount Rettenstein. The upper age limit of the grey marly limestone is constrained with ammonites, determined in the overlying red nodular limestone, numerical age after Gradstein et al. (2012). Revised radiolarian dating of samples from the Dürrnberg Formation is shown for comparison.

Fig. 3. A. View of the complete Mount Rettenstein complex from the southwest. B. Position of the studied section in the Weitenhaus cirque, the oval indicates the location where the studied samples were collected. C. Schematic sketch of the structural build of Mount Rettenstein with the three main tectonic units (from Auer et al. 2006). Structural Unit I: The primary part of the Tirolic mega-unit which, in contrast to the higher structural units, stayed ( more or less) in place relative to the basis of the Upper Tirolic thrust sheet. In the Mount Rettenstein region, Permian to early Middle Triassic strata make up the succession above the Greywacke Zone basement (Ganss et al. 1954). Structural Unit II: This intermediate, rather thin sheet is mainly made up of a laterally variable mega-slide succession of the Middle Jurassic Hallstatt Mélange. It is thought to have achieved its present position in the hangingwall of a normal fault (Auer et al. 2006). Structural Unit III: The topmost Mount Rettenstein unit corresponds to the Lower to Upper Jurassic Mount Rettenstein succession sensu stricto in the sense of Auer et al. (2009). It is suggested to have been emplaced along a thrust fault (Auer et al. 2006).

Fig. 2. Stratigraphic table with lithostratigraphic names and main tectonic events of the Jurassic of the Northern Calcareous Alps with their variations depending on the palaeogeographic position (after Gawlick et al. 2009). The different facies belts and therefore also the formations belong to depositional realms, which roughly correspond to the later formed tectonic units. The outer shelf region can only be reconstructed from blocks in Middle to Upper Jurassic mélanges and is, therefore, not completely understood in all details. The grey limestone succession from Mount Rettenstein shows characteristics of both the Scheibelberg and the Dürrnberg formations (in bold). Estimated palaeogeographic positions of the studied section are indicated. Abbreviations: Cret., Cretaceous; Fm., Formation; Lst., Limestone.
