Geography
| Country: | United States | State/province: | Louisiana | County: | Orleans |
| Coordinates: | 30.1° North, 90.0° West (view map) | ||||
| Paleocoordinates: | 30.1° North, 90.0° West | ||||
| Basis of coordinate: | based on nearby landmark | ||||
| Geographic resolution: | local area |
Time
| Period: | Quaternary | Epoch: | Holocene |
| 10 m.y. bin: | Cenozoic 6 | ||
| Key time interval: | Holocene | ||
| Age range of interval: | 0.01170 - 0.00000 m.y. ago |
Stratigraphy
| Formation: | New Orleans Barrier Trend | ||||
| Stratigraphic resolution: | bed | ||||
| Stratigraphy comments: Five late Quaternary stratigraphic units are exposed at the Lake Carmel borrow pit. These in ascending order are : 1) deltaic equivalents of Deweyville terrace alluvium (Wisconsin); 2) a buried soil zone, "Little Woods paleosol" (late Wisconsin-early (Pleistocene); 3) bay-sound clay, "Michoud Formation" (middle Holocene); 4) barrier bar sand of the New Orleans trend (middle Holocene); 5) St Bernard prodeltaic and delta front deposits (late Holocene). This collection is from the basal Barrier Bar unit (New Orleans trend). The Michoud Formation grades upward into a thin discontinous clayey sand containing abundant mollusk shells. This clayey sand unit forms the bottom of a locally, shelly, fine to coarse sand unit containing numerous burrow systems. Radiocarbon dates on peat collected from this unit yield dates of 11,090 and 29,860 years, although most authors consider the unit to have accumulated between 4-5,000 years ago. The unit is 1.5m thick. The collection comes from depth 4.5-6.0 m | |||||
Lithology and environment
| Primary lithology: | fine,coarse,shelly/skeletal unlithified sandstone |
| Includes fossils? | Y |
| Lithology description: Locally, shelly, fine to coarse sand JA: I am scoring this as unlithified because the sand is Holocene, isn't calcareous, overlies a soil, and includes a peat, plus the entire section is non-carbonate | |
| Environment: | coastal indet. |
| Glacial or sequence phase: | transgressive |
| Geology comments: Part of a sub-surface sand body that has been variously labeled "New Orleans barrier island". | |
Taphonomy
| Modes of preservation: | body |
| Size of fossils: | macrofossils |
Collection methods and comments
| Collection methods: | bulk,field collection |
| Reason for describing collection: | paleoecologic analysis |
| Collection method comments: All taxa collected and identified G. Mollyn. Unknown repository, though possibly Tulane University | |
| Taxonomic list comments:Exhaustive for mollusca. Key to abundance data: a=abundant; c=common; mc=moderately common; u=uncommon; r=rare. | |
