Stratigraphy
Local section: | Siemien | Local bed: | 4.8 m | ||
Local order: | top to bottom | ||||
Stratigraphic resolution: | bed | ||||
Stratigraphy comments: SPECIFIC STRATIGRAPHY: Collection froms horizon between 4.7 and 4.9 m below top of section. Deposits are less than 10 m thick in total, overlain by Quaternary sands, and overlying Maastrictian sediments.
AGE: Assigned to Bartonian on the basis of similarity of faunal assemblage to Bartonian of England. Furthermore, analysis of planktonic foraminifers shows the unit to be the Globigerapsis semiinvolute Zone, that is in the lower part of the Upper Eocene, and on the basis of coccoliths to be in the Discoaster nodifer biozone, that is uppermost Middle and lowermost Upper Eocene. |
Lithology and environment
Primary lithology: | concretionary,glauconitic,phosphatic,green poorly lithified sandstone |
Includes fossils? | Y |
Lithology description: Green, quartz-glauconite, phosphorite-bearing sands with very numerous phosphorite lumps or single concretions. | |
Environment: | offshore |
Glacial or sequence phase: | transgressive |
Geology comments: The Upper Eocene sequence is represented by transgressive marine series. Most taxa occupy neritic and littoral and warm-temperate conditions. Numerous corals suggest normal salinity. Probably accumulaed in 10-90 m of water depth. |
Taphonomy
Modes of preservation: | body,original aragonite,original calcite |
Size of fossils: | macrofossils |
Preservation of anatomical detail: | poor |
Collection methods and comments
Collection methods: | field collection |
Reason for describing collection: | taxonomic analysis |
Collection method comments: Macrofauna are housed in the Geological Instiutute (IG) of Poland. | |
Taxonomic list comments:Exhaustive for bivalvia and apparently complete for gastropods (although this is a meagre fauna). Includes all macrofossils. |
