Regressive intertidal sequences, with well developed zonation of flora and fauna, occur extensively around the margins of the 2 major SA gulfs and within small embayments along the exposed coastline of Eyre Peninsula. This paper summarises and...

Likely excavation conditions during the proposed deepening of the boat channel at St. Kilda were investigated by drilling and seismic refraction surveys. Results showed 2 to 3 m of St. Kilda Formation (loose shelly sand) overlying up to 0.2 m of...

As part of studies on Stratigraphy and chronology of coastal Quaternary sediments in SA, M. vertebralis was dated using radiocarbon 3 and amino acid racemization dating. Results suggest reef connecting Wardang and Goose Islands, rather than being...

The extent of racemization (epimerization) for a range of amino acids in specimens of the fossil bivalve Anadara trapezia suggest a Penultimate Interglacial age (oxygen isotope stage 7) of approximately 200,000 years B.P., consistent with the...

The application of amino acid racemization reactions is explored for regional chronostratigraphic correlation of Last Interglacial marginal marine sediments. The extent of racemization evident for a range of amino acids in several molluscan species...

Examines numerous outcrops illustrating the geological and tectonic evolution of the region. This excursion is based on the EPIC tour of the Geological Society of Australia 8th Australian Geological Convention excursion series in February 1986. This...

Study of the top 2 cm of sediment from 13 vibrocores. 7 facies are described. Relative abundances of foraminifera are determined for the 0.125 - 0.25 sediment size fraction distribution patterns indicates ecology and sedimentary environment.

Vibrocores from the samphire marshes south of the North Arm of the Port River are used to interpret the shallow subsurface stratigraphy. 2 marine sequences of Holocene and Late Pleistocene age, consist of saturated, unconsolidated and largely...

A shallow refraction seismic survey was conducted along the causeway adjacent to the boat channel at St. Kilda, during its exposure at low tide. The aim of the survey was to determine the thickness of the St. Kilda Formation consisting of shelly sand,...

Shallow drilling (<30 metres) at 14 sites intersected a regressive coastal sequence of Quaternary bioclastic sediments deposited in coastal aeolian, littoral, lagoonal and evaporative-lagoonal environments. Major calcrete carapaces assist the...

Amino acid racemization data provide the basis for a predictive model for relative dating of late Quaternary coastal sequences. The extent of racemization on Last Interglacial fossils represents a linear function of latitude in southern Australia....

Metropolitan Adelaide is founded on a wide variety of soils that overlie sediments and rocks. Some of the soils and sediments react to seasonal and human-induced changes in water content with marked changes in volume. The black earths and...

Drill core from samphire and mangrove marshes north of Gillman - Wingfield are used to interpret the shallow sub-surface stratigraphy of the region. A Holocene marine sequence up to 8 metres thick overlies Late Pleistocene alluvial (Pooraka Formation)...

This work aims to thoroughly assist the student and collector in identifying the Quaternary molluscs preserved in SA rocks. Many of the molluscan fossils occurring in Late Pleistocene deposits are representatives of still living species, although...

The Streaky Bay and Nuyts 1:250 000 map areas are located on the western side of Eyre Peninsula. Precambrian greenschist and amphibolite facies metamorphics of the Gawler Platform are intruded by Lower Proterozoic or Carpentarian granites, gneisses...

Three cable tool holes from 50 to 70 feet deep have been put down to determine foundation conditions for proposed extensions to the Port Pirie Hospital. The holes indicate a horizontal succession of approximately 12 feet of St. Kilda Formation...

It is proposed to construct a railway crossing of Spencer Gulf and its tidal flats, two miles north of Port Augusta. Geological investigations, mainly surface mapping and cable tool drilling, have shown 140ft of sediments of Tertiary to Recent age in...

This paper sets out the stratigraphy of late Cainozoic deposits in the southern part of South Australia. The study includes the Murray, St Vincent and Spencer Gulf, West Coast and Eucla Basins and the adjoining uplands. Work has been concentrated on...
