NMB #10699 - Belmont Fm (Carriacou) (Miocene of Grenada)

Where: Grenada (12.5° N, 61.4° W)

• Paleocoordinates: 13.2° N, 57.4° W (Wright 2013)

• coordinate estimated from map

• outcrop-level geographic resolution

When: Kendace Calcareous Silt Member (Belmont Formation), Early/Lower Miocene (23.0 - 16.0 Ma)

• 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.

• bed-level stratigraphic resolution

Environment/lithology: deep-water; poorly lithified, calcareous siltstone

• Probably deposited in deep-water, approximately greater than 200, but no deeper than 800 m.
• 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

Size class: macrofossils

Reposited in the NMB

• Naturhistorisches Museum, Basel, Switzerland.
