Stratigraphy
Geological group:Coastal Formation:Bowden
Stratigraphic resolution:bed
Stratigraphy comments: STRATIGRAPHIC RELATIONS: From Pickerill et al. (1998). Bowden Formation is the uppermost stratigraphic unit of the Lower Coastal Group. The top of the formation is defined by the nonconformably overlying, early Pleistocene Old Pera Beds of the Upper Coastal Group. AGE: Late Pliocene. The unit was formely regarded as Miocene in age, even Oligocene, but foraminiferal and planktic gastropod biostratigraphy points to a late Pliocene age. STRATIGRAPHIC POSITION: Unknown position within formation.
Lithology and environment
Primary lithology:pebbly,shelly/skeletal unlithified conglomeratic gravel
Includes fossils?Y
Lithology description: SPECIFIC LITHOLOGY: Imperfectly consolidated gravel consisting of pebbles and grains of igneous rocks, limestone, and other sorts of rock in a marly matrix. LITHIFICATION: Unlithified, based on observation of specimens.
Environment:offshore
Geology comments: ENVIRONMENT: The conglomeratic lithofacies are interpretated as a product of sediment gravity flows, more specifically turbidites, and constitute and integral component of the Bowden Shell bed. The marlstone lithofacies is interpreted as a product of pelagic and hemiplegaic deposition from low density turbidity currents, or possibly even bottom water nepheloid layers.
