Stratigraphy
| Formation: | Lugagnano | ||||
| Stratigraphy comments: VERBATIM STRATIGRAPHY: A hydrocarbon seep complex of late Pliocene age has been recently described in detail from strata of the Argille Azzurre (Lugagnano Formation). Discrete hydrocarbon-imprinted carbonate bodies of different thick- ness and degree of lithification and host muddy sediment punctuate the Stirone section at the Zanclean/Piacenzian boundary. |
Lithology and environment
| Primary lithology: | poorly lithified mudstone |
| Includes fossils? | Y |
| Lithology description: VERBATIM LITHOLOGY: Discrete hydrocarbon-imprinted carbonate bodies of different thick- ness and degree of lithification and host muddy sediment. LITHIFICATION: Poorly lithified based on figured specimens. | |
| Environment: | deep-water indet. |
| Geology comments: VERBATIM ENVIRONMENT: A hydrocarbon seep complex.....the benthic foraminifera and mollusk fauna indicate a depositional depth not exceeding 500 m (Cau et al. 2015). | |
Taphonomy
| Modes of preservation: | body,mold/impression |
| Size of fossils: | macrofossils |
| Preservation of anatomical detail: | good |
| Bioerosion: | none |
| Encrustation: | none |
| Spatial resolution: | autochthonous |
Collection methods and comments
| Collection excludes: | all microfossils |
| Collection methods: | surface (in situ),field collection,survey of museum collection |
| Reason for describing collection: | taxonomic analysis |
