Geography
| Country: | Grenada |
| Coordinates: | 12.5° North, 61.4° West (view map) |
| Paleocoordinates: | 12.2° North, 60.2° West |
| Basis of coordinate: | estimated from map |
| Geographic resolution: | outcrop |
Time
| Period: | Neogene | Epoch: | Miocene |
| 10 m.y. bin: | Cenozoic 5 | ||
| Key time interval: | Early/Lower Miocene | ||
| Age range of interval: | 23.03000 - 15.98000 m.y. ago |
Stratigraphy
| Formation: | Belmont | Member: | Kendace Calcareous Silt | ||
| Local section: | Bretache Point | ||||
| Stratigraphic resolution: | bed | ||||
| Stratigraphy comments: The principal, nominal sedimentary units of the mid-Tertiary succession of Carriacou are the Belmont Formation (lower Miocene), Kendeace Formation (lower Miocene), Carriacou Formation (middle Miocene) and Grand Bay Formation (middle Miocene). The collection originates from the Kendace Calcareous Silt Member of the Belmont Fm. Jung (1971) assigns an Early Miocene age. The age is determined relative (underlying) to the Grand Bay Formation, as the other units are small and poorly preserved. | |||||
Lithology and environment
| Primary lithology: | poorly lithified calcareous siltstone |
| Includes fossils? | Y |
| Lithology description: Calcareous siltstone. From specimens presented in photgraphic plates most material from Carriacou appears to be from poorly-lithified as opposed to cemented, or unconsolidated sediments. No information provided in text | |
| Environment: | deep-water indet. |
| Geology comments: Probably deposited in deep-water, approximately greater than 200, but no deeper than 800 m. | |
Taphonomy
| Modes of preservation: | body |
| Size of fossils: | macrofossils |
| Preservation of anatomical detail: | good |
