| Geographic resolution: | outcrop |
Time
| Period: | Quaternary | Epoch: | Holocene |
| 10 m.y. bin: | Cenozoic 6 | ||

Stratigraphy
| Local section: | Nova Brasilia | ||||
| Regional section: | Santa Catarina | ||||
| Stratigraphic resolution: | bed | ||||
| Stratigraphy comments: 4 km long, 420 m wide deposit; thickness varying between 0.6 and 6.0 m. Radiocardbon ages of shells from this deposit indicate an age or 4,490 +/- 200 yrs BP. | |||||
Lithology and environment
| Primary lithology: | "cross stratification",shelly/skeletal sandstone |
| Includes fossils? | Y |
| Lithology description: Tabular great scale cross-bedded units composed alternately by more sandy and more shelly beds | |
| Environment: | coastal indet. |
| Geology comments: Lagoonal and estuarine, and beach and shall marine sands (latter two more likely for this collection). Originated as lagoonal and marine beach facies, tidal channel facies, including flood tidal deltas, and transgressive residual shell facies (lag deposits). Allocthonous in origin. Cross-bedding and reverse grading from migration of bedforms suggest transport of these materials as tractional current bars. | |
Taphonomy
| Modes of preservation: | body |
| Size of fossils: | macrofossils |
| Spatial resolution: | allochthonous |
Collection methods and comments
| Collection excludes: | some macrofossils |
| Reason for describing collection: | general faunal/floral analysis |
| Collection method comments: Listed based on review of previous literature. Not collected in this study | |
| Taxonomic list comments:Only includes most abundant species. See Forti-Esteves (1986), Mendes (1993), and Pitoni (1993) for complete lists (all spanish/portugese). Faunal list looks representative. | |
