Stratigraphy
Lithology and environment
| Primary lithology: | fine lithified sandstone |
| Secondary lithology: | tuff |
| Includes fossils? | Y |
| Lithology description: Ukari formation- fine grained sandstone. In central and southeastern parts of the area, the Ukari Fm grades laterally into a sandstone-siltstone alternation of turbidite facies (Horinouchi Fm). A tuff bed (T-3 tuff) is interbedded in the middle of the fine-grained sandstone of the Ukari Fm, and the tuff layer is less than 1m thick. | |
| Environment: | coastal indet. |
| Geology comments: sandstone facies (Ukari Fm) said to be deposited on a shelf. | |
Taphonomy
| Modes of preservation: | body,original aragonite,original calcite |
| Size of fossils: | macrofossils,mesofossils,microfossils |
| Articulated whole bodies: | some |
| Disassociated major elements: | some |
Collection methods and comments
| Collection excludes: | some microfossils |
| Collection methods: | bulk,field collection |
| Reason for describing collection: | general faunal/floral analysis |
| Collection method comments: There were 200-1500 individual forams present in each sample. The number of mollusc individuals per sample is not reported. Forams were extracted from blocks of sediment weighing 1-2kg each. | |
| Taxonomic list comments:Molluscs reported are all observed taxa in the given area. Forams in list are only those that were analyzed for oxygen isotope ratios and include only the most common foram species. | |
