Stratigraphy
| Formation: | Schnoll | Member: | Guggen | ||
| Local section: | Adnet Eisenmann Quarry | Local bed: | bed overlained by Marmorea Crust | ||
| Stratigraphic resolution: | bed | ||||
| Stratigraphy comments: A thin layer of red (so-called Enzesfeld) limestone overlains the Rhaetian limestones and is capped by ferromanganeous Marmorea Crust | |||||
Lithology and environment
| Primary lithology: | condensed,ferruginous,shelly/skeletal,red or brown lithified packstone |
| Includes fossils? | Y |
| Lithology description: Red condensed limestone with ammonites and brachiopods. Microfacies: echinoderm-foram biomicrite with gastropods. Intercalated hardgrounds may consist of brownish-yellow phosphatic sediment or of dark Fe/Mn oxides. | |
| Environment: | deep subtidal ramp |
| Glacial or sequence phase: | lowstand systems tract |
| Geology comments: Sediment starvation may have been caused by current activity combined with strongly reduced input of carbonate mud due to the widespread drowning in the Middle Hettangian. | |
Taphonomy
| Modes of preservation: | body,mold/impression,original calcite,replaced with calcite |
| Size of fossils: | macrofossils |
Collection methods and comments
| Collection excludes: | all microfossils,difficult macrofossils |
| Collection methods: | mechanical,field collection |
| Reason for describing collection: | taxonomic analysis |
