About 70% of Kangaroo Island soils are acidic and continued cultivation will cause increasing acidity. The best treatment is application of lime sand from deposits of Holocene Semaphore Sand along the southern coast. Material tested has high calcium...

Investigation aimed to evaluate environments of deposition and problems of dating the Cadna-owie Formation and basal Bulldog Shale.

Surficial sediments are predominantly bioclastic, cool-temperate carbonates. Benthic foraminifera Elphidium crispum', a shallow water species, and 'E. macelliforme, favouring deeper water, provide useful numerical ratio which correlates with water...

Interprets Bridge Oil / Target Exploration seismic data and shipborne magnetic data.

At the Anna Coalfield, the November 1976 appraisal drilling by SADME of 2 rotary mud, partly cored vertical boreholes with a total penetration of 159.62 m (including 28.36 m of continuous ?NQ coring over the coal-bearing section) has confirmed the...

This study covers a southern lobe of the Eromanga Basin known as the Frome Embayment, which extends W-E from the Flinders Ranges to the Barrier Ranges, and southwards from the vicinity of Moolowatana Station to the Scott Hill-Mundaerno Hill region....

The Duntroon Basin is an ESE-trending Mesozoic to Tertiary sedimentary embayment in the continental shelf, located SE of the Great Australian Bight Basin and west of Kangaroo Island. The report includes a discussion of the stratigraphy based on...

The Quaternary stratigraphy in the trench was examined within the Strzelecki dunefield near Montecollina Bore, near Big John Creek and to the south (mainly Balcanoona). Longitudinal and transverse dune sands demonstrated a history of episodic dune...

Inspection of 57 pits of 82 sites revealed that most pits are located on stranded coastal dunes of Pleistocene Bridgewater Formation. Material has also been won from interdunal lagoonal dolomite of Padthaway Formation. These materials are limited to...

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...

Known and inferred geological characteristics and age relationships of the rocks infilling the wholly deeply buried Palaeozoic Warburton Basin are described. Depositional, structural and alteration aspects of the rocks are also mentioned, as they may...

Sediments deposited in environment similar to present day inland drainage system.

Documents the contribution of biogenic bioclastic and terrigenous clastic components to Holocene shelf sedimentation to provide framework for assessing Quaternary shelf evolution. Quaternary sea level fluctuations have promoted terrigenous carbonate...

The distinctive large, benthonic, shallow marine foraminifer Lepidocyclina howchini has been identified, with an associated benthonic microfauna, in limestone in a borrow pit located in the Bremer Valley 3 km east of Kanmantoo. The limestone is a...

49 samples of calcareous sediments from the Bridgewater Formation, Glanville Formation and St Kilda Formation, collected along the west coast of Eyre Peninsula were examined in thin section. Factors such as the extent of recrystallization and the...

Thin sections of 3 specimens were examined for traces of organic remains, metallic minerals and the metamorphism of the rocks. Contains petrographic reports.

The distribution, physical properties and accumulation rates of terrigenous sediment originating from the Burdekin River are examined. The relationship between recent sediments and sea level changes are used to derive model of late Quaternary...

Vibrocores and observations from within the intertidal zone demonstrate that only limited coastal sedimentation has occurred during the Holocene. Morphological development of the coast has been contained and controlled by older lithologies. Large...

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.
