Upper Jurassic to Lower Cretaceous Dasycladales of the Northern Calcareous Alps: the state of knowledge
Lithostratigraphy and Facies Calcareous Algae are known from the following units: The Plassen Limestone (equivalent with the Lerchkogel Limestone) is typical for a lagoonal development with patch-reefs. The detrital Tressenstein Limestone represents proximal platform debris and is intercalated with the allodapic Barmstein Limestone. The Barmstein Limestone is interpreted as a seismoturbidite facies and represents allodapic sediments, which are intercalated with the well bedded hemipelagic Oberalm Beds.
The platform or platform-derived carbonates are characterized by a rich algal flora. The Chlorophyta are dominated by the Dasycladales, while Siphonales and Charales are of subordinated importance. Additionally, the family Solenoporaceae is dominant among the Rhodophyta. |
