Formation: | Belmont | ||||
Local section: | Kendace 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 undifferentiated Belmont Formation, which forms the oldest part of the Carriacou Miocene succession. The collection was obtained from the tip of Kendace Point (silt member of Belmont Fm) and therefore probably lie above the limestone lens in undifferentiated Belmont Fm (NMB #10747). |
Lithology and environment
Lithology description: No lithology specified. Could be either calcareous fine siliciclastic or limestone? 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: | coastal indet. |
Geology comments: Locally the water was probably shallow; no genera suggest deeper-water environments. |
