Stratigraphy
| Formation: | Dry Creek Sands | ||||
| Stratigraphic resolution: | formation | ||||
| Stratigraphy comments: STRATIGRAPHIC RELATIONS: Presumably unconformably underyling Pliocene Hallett Cove Sandstone (Pleistocene-Recent in Fig. 2 of Ludbrook 1954) The Dry Creek Sands are a correlate of the Bookpurnong Fm (Beu and Darragh 2001). THICKNESS: Typically the Dry Creek Sands are less than 200 ft thick based on Fig. 2 of Ludbrook (1954). AGE: Previously regarded as Pliocene in age (Ludbrook 1954, 1963). However more recent idependent assessments of foraminifera and dinoflagellates (Brown and Stephenson 1991; Macphail and Kellett 1993) and Mollusca (Beu and Darragh 2001) suggest that the lower Dry Creek Sands (greater than 105-115 m) are of Bairnsdalian-Mitchelian age (latest Middle Miocene-early Late Miocene). A Late Miocene age is adopted here = Mitchelian. STRATIGRAPHIC POSITION: Composite list for Dry Creek Sands and from unknown position within bore, possibly multiple beds, but more than likely below ~300 feet (~105 m). | |||||
Lithology and environment
| Primary lithology: | fine,shelly/skeletal,gray,white unlithified sandstone |
| Includes fossils? | Y |
| Lithology description: SPECIFIC LITHOLOGY: Ligh-grey-silery, fine, sharp sands and clays, with intercalated bands of grey and white limestone; pale-grey shelly sands. LITHIFICATION: Unlithified, possibly occasionally poorly-lithified. | |
| Environment: | coastal indet. |
| Geology comments: ENVIRONMENT: Deposited in a shallow bay or gulf after depression of older strata, submerged during the early Tertiary; sandy bay, protected. Not an estuarine or restricted embayment fauna, so here assigned to a "siliciclastic-coastal indet." environment. | |
Taphonomy
| Modes of preservation: | body,original aragonite,original calcite |
| Size of fossils: | macrofossils |
| Preservation of anatomical detail: | excellent |
Collection methods and comments
| Collection methods: | core,field collection |
| Reason for describing collection: | taxonomic analysis |
| Collection method comments: COLLECTOR: Collected by multiple parties during the irregular construction of bores within the vicinity of Adelaide. Reported on by previous authors including Tate (1890, 1898), Tate and Dennant (1896), Hall and Pritchard (1902), Howchin (1914, 1928) and Chapman (1916). These authors reported piecemeal this fauna, while Ludbrook (1954-1956) presents more detailed taxonomy and thorough covereage of all bores. REPOSITORY: Most material reposited in Tate Collection, University of Adelaide, while some is preserved in the MNHM in Paris and BMNH. | |
| Taxonomic list comments:COVERAGE: Exhaustive for molluscan groups. No other taxa specifically listed. NOMENCLATURE: Authoritative series of publications, but with rather oudated nomenclature. This is remedied by revisions of Australian Mollusca by Darragh (1970), and various publications by Darragh (post 1970). | |
