Geography
Country:Grenada
Coordinates: 12.5° North, 61.4° West (view map)
Paleocoordinates:12.3° North, 60.1° 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 - 15.97000 m.y. ago
Stratigraphy
Formation:Belmont Member:Kendace Calcareous Silt
Local section:Belvedere
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
Collection methods and comments
Collection methods:field collection,survey of museum collection
Reason for describing collection:taxonomic analysis
Museum repositories:NMB
Collection method comments: Naturhistorisches Museum, Basel, Switzerland.
Taxonomic list comments:Exhaustive for Mollusca. Later publications may list non-molluscan taxa from these units. These are not available at this time.
