The relations between the relatively thick Callovian to Oxfordian micritic and partly siliceous sequence and the ammonite finding (Krystyn et al., 1994) is not clearified in detail until now due to the lack of dateable organism. The some tens of metres thick sequence of cherty limestones overlying the latest radiolarian findings may reach the Tithonian similar to the sequence in the Slowenian Trough (Buser, 1979). Fig. 1: Stratigraphic table and lithostratigraphic names of the Austroalpine. Lithostratigraphy Gawlick, H.-J., Missoni, S., Schlagintweit, F., Suzuki, H., Krystyn, L. & Lein, R. Northern Calcareous Alps and Drau-Range Schattwald Beds (Schattwalder Schichten) Validity: invalid; first description and age dating by Reiser (1920); in detail investigated by Fabricius (1966), and by McRoberts et al. (1997). Type area: ÖK 84 Reutte; western Northern Calcareous Alps. Type section: ÖK 84 Reutte; in the Tannheim valley southwest of the village Schattwald (Tyrol). Reference section(s): not designated; probably Kendlbach section (ÖK 94 Hallein; see chapter Kendlbach Formation), or Lorüns quarry (details in McRoberts et al., 1997). Derivation of name: after village Schattwald, near the town Reutte (Tyrol). Synonyms: non.

Gratis scripts for students and pupils! Fossils: mostly bivalves (details in Tollmann, 1976a; McRoberts et al., 1997). Origin, facies: siliciclastic influenced succession in the framework of a regressive/transgressive cycle around the Triassic/Jurassic boundary. Chronostratigraphic age: Latest Triassic (Rhaetian), probably to base of the Hettangian (e.g., Zacher, 1966; Fabricius, 1966; McRoberts et al., 1997). The Upper Schattwald shales are equivalent to the Tiefenbach Member of the Kendlbach Formation (e.g., Golebiowski, 1990). For discussion of the Triassic/Jurassic boundary in the Northern Calcareous Alps see e.g., Hillebrandt & Ulrichs (2008). Biostratigraphy: Late Rhaetian to earliest Jurassic (Planorbis zone). Thickness: 1-3 m; locally up to 7 m. Lithostratigraphically higher rank: non. Subdivision: no subdivision. Underlying units (footwall boundary): Rhaetian Dachstein Limestone, Kössen Formation. Overlying units (hangingwall boundary): normally Kendlbach Formation (e.g., Golebiowski, 1990; Hillebrandt & Ulrichs, 2008), but also Schnöll Formation to Allgäu Formation – “Bunte Lias-Cephalopenkalke und Grauer Liasbasiskalk” according to Fabricius (1966); for details see Tollmann (1976a).

Gratis scripts for students and pupils! Geographic distribution: northern part of the eastern Northern Calcareous Alps, and widespread in the western Northern Calcareous Alps (Bavaric units). The Upper Schattwald Formation of McRoberts et al. (1997) belong to the Jurassic. Therefore the “Lorüns-Oolith” represent a shallower equivalent of the Enzesfeld Formation. Kalksburg Series (Kalksburger Schichten) Validity: invalid; first description by Solomonica (1934); detailed investigations in Rosenberg (1961, 1965); needs revision and formalization (compare Wessely, 2006 – Kalksburg Formation, but without definition). Type area: ÖK 58 Kalksburg; north-easternmost Northern Calcareous Alps. Type section: ÖK 58 Kalksburg; old quarry in Kalksburg in the easternmost part of the Schubert park in the town Kalksburg. Reference section(s): not designated. Derivation of name: after the small town Kalksburg in southwestern Vienna, near the border to Lower Austria. Synonyms: non. Lithology: brownish-grey marls, sandstones, siltstones and limestones. Fossils: ammonites, bivalves (details in Rosenberg, 1961). Origin, facies: shallow-water sediments, partly near-coastal with siliciclastic, continental influence in a general deepening upward trend. Chronostratigraphic age: Hettangian to Sinemurian. Upper Sinemurian is unproven (Rosenberg, 1961).

Gratis scripts for students and pupils! Thickness: some tens of metres; normally 30-40 m. Lithostratigraphically higher rank: non. Subdivision: no subdivision. Underlying units (footwall boundary): Dachstein Limestone resp. Schattwalder Schichten, Kössen Formation. Overlying units (hangingwall boundary): Allgäu Formation resp. Kirchstein Limestone (?late Sinemurian or Pliensbachian), cherty grey Early Jurassic basinal sediments; partly in transition to the Adnet Formation. Geographic distribution: northern part of the eastern Northern Calcareous Alps (Rosenberg, 1954, 1965; Tollmann, 1976a). This is manifested by the succession Luftstrasse near the town Kirchberg/Pielach (Schwingenschlögl, 1981; Böhm, 1992).

Gratis scripts for students and pupils! Adnet Group The Adnet Group was introduced by Böhm et al. (1999), formalized and defined by Böhm (2003). In addition to the original definition of Böhm (2003) we include in the Adnet Group the reddish Hierlatz Limestone, which is genetically connected to the upper Schnöll and lower Adnet Formation, and lithostratigraphically partly connected with the upper Schnöll and lower Adnet Formation. Schnöll Formation (Schnöll-Formation) Validity: valid; first description by Wähner (1903). Completely revisited by Böhm (1992), and Böhm et al. (1999). Böhm et al. (1999) defined the term Schnöll Formation, more details in Böhm (2003). Type area: ÖK 94 Hallein; Adnet quarries and surrounding areas in the Osterhorn Mountains. Type section: ÖK 94 Hallein; Adnet quarry XVII, Langmoos quarry (for details see Gallet et al., 1993; Böhm, 2003). Reference section(s): a small outcrop in a cliff immediately to the southeast of quarry XVI (for location and numbers of the quarries see Kieslinger, 1964; Böhm, 2003); close to the Langmoos quarry is proposed as reference section as well as the southern part of quarry XXXI, the Schnöll quarry (for details see Böhm, 2003). | ||||||||||||
