Ein Beitrag zur Feinstratigraphie der Hallstätter Kalke am Sirius-Kogel (Bad Ischl, Oberösterreich)

GPM 3, 7, p. 1–47

One section of 160 m thick, so-called Hallstätter limestone at Sirius-Kogel in the south of Bad Ischl, Oberösterreich, is studied.
For the first time it was mentioned by other authors that the Hallstätter limestone at Sirius-Kogel are only of Norian age. The microfauna, particularly conodonts, holothuroids, crinoids and microproblematic remains, also foraminifers yielded by dissolution with acidic acid indicates Upper Ladinian? Karnian and Norian age.
The lower part of the section at Sirius-Kogel (75 m thick) consists of micritic limestone with filaments, pellets and scarce biogen material; they don't belong to typical Hallstätter limestone, much more we attempt to provide them to Reiflinger limestone.
The higher part of the section (85 m thick) is a typical Hallstätter limestone (biomicritic limestone).
The genesis of sedimentation of the 160 m thick section is very complicated; nearly the whole limestone at Sirius-Kogel consists of fillings of syngenetic tectonic fissures. The basal layers of Langobardian?, Cordevolian age have fissures filled only with spatit or sterile micrite.
The Julian limestone are filled with internal sediments of two ore more phases, certainley of the same age. Above them are fissures with fillings of Middle Norian age; the fissures partly are very fine (millimetre) for that reason by maceration we receive a mixed microfauna consisting of Julian and Middle Norian age.
The Julian limestone are overlain by thin layers (alltogether 6 m) of Tuvalian age with a high-grade condensation; the result is a mixed fauna of Tuvalian and lower Norian age. The following Middle and Upper Norian Hallstätter limestone is not condensed.
Finally same holothurian sclerites are discribed; two of them are new species.
