Geography
Country:Australia State/province:South Australia
Coordinates: 37.8° South, 140.6° East (view map)
Paleocoordinates:52.6° South, 137.4° East
Basis of coordinate:based on nearby landmark
Geographic resolution:outcrop
Time
Period:Paleogene Epoch:Oligocene
Stage:Chattian 10 m.y. bin:Cenozoic 4
Key time interval:Chattian
Age range of interval:27.82000 - 23.03000 m.y. ago
Stratigraphy
Formation:Gambier Limestone Member:Camelback
Stratigraphic resolution:group of beds
Stratigraphy comments: Camelback Member, Janjukian, planktonic foram zones P21-P22 according to Fitzgerald 2004. Overall, the formation ranges in age from top P20 to no older than at least basal N5 planktonic zones (White 1995) but the Camelback member is late Oligocene (Li et al. 2000).
Lithology and environment
Primary lithology:shelly/skeletal,white poorly lithified packstone
Includes fossils?Y
Lithology description: Limestone is generally soft to friable bryozoan rudstone to grainstone to packstone to wackestone with layers and pockets rich in large bryozoans and echinoids or bivalves, brachiopods and gastropods. Muddy and sandy sediments are crudely layered on a scale of 20 to 30 cm. Lenses of diverse fossils are generally porous and from 20 to 30 cm high and 50 to 100 cm long. "Slightly lithified" according to James & Bone (1989).
Environment:deep subtidal shelf
Geology comments: A high abundance of cibicidiids and other middle to outer shelf foraminifers suggests that the Gambier carbonates largely accumulated at 50–150 m (Li et al. 2000). Environment interpreted to be inner and middle shelf by White (1995), so deep subtidal environment is consistent.
