Investigations since 1984 have assessed the groundwater availability. The groundwater supplies are obtained from an extensive unconfined aquifer. The investigations included drilling of investigation wells, aquifer testing, studies of the recharge...

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...

Mapping, trenching and auger drilling have shown that dune sands overlie fluvio lagoonal clayey sand which overlies stranded beach Holocene sand. Indicated and inferred reserves total 66 000 tonnes of plaster and mortar sand and 384 000 tonnes of...

This report forms contribution to the working group on Australian Proterozoic basins. The best dated early Proterozoic sequence is the Hutchison Group of the Gawler Craton. Metasediments of the Willyama Complex are correlated with this group and an...

Zircons from altered granite in basement below the Cooper Basin, between 9353 and 9377 feet, are suitable for uranium - lead isotope dating.

5 spore / pollen zones and 3 dinoflagellate zones are recognised in Toodla 1, ranging from late Jurassic to Late Albian. The Mesozoic units penetrated by this well on palynological evidence are younger than traditionally recognised in other parts of...

The Mulgathing Complex, an Archaean metasedimentary sequence with interlayered mafic and possibly acid volcanics, forms the basement of larger part of the northern Gawler Craton. These rocks have been complexly folded, subjected to granulite facies...

Program ISOCHRON is a two-error regression program for calculation of Rb Sr isochron ages and initial Sr Sr ratios. Originally written for a Cyber mainframe, the program has been modified for NEC-APC III, IBM-PC and Olivetti M24 personal computers....

Model to enhance the existing facility to calibrate density and neutron porosity probes has been constructed. This forms part of set of calibration models for the slim hole logging industry. The new model has 2 zones, 1 of high porosity and the other...

Radiocarbon dates were measured from non-marine shelly fossils and from calcareous paleosols in the Lake Frome area of South Australia (Tarkarooloo Basin, Callen and Tedford, 1976), mainly in an attempt to establish the sequence of late Quaternary...

The Kalinjala Mylonite Zone (new name) is a major linear zone of intense ductile deformation extending the length of eastern Eyre Peninsula, from Sleaford Bay in the south, to west of the Middleback Ranges in the north. It was formed nearing the end...

Reserves of 151 tonnes of basalt are inferred.

18 drill cuttings samples taken from 4 mineral exploration holes were examined for making palynological age determinations. 11 samples were variously identified as being sediments of Middle Miocene freshwater or Early Cretaceous marine facies.

Major units present are 2 suites of Middle Proterozoic granite and Middle Pleistocene calcarenite. The older granite suite has an age of about 1585 Ma, while the other suite had intrusive age of 1457 +- 25 Ma. The granites are enriched in K2O and SiO2.

The Carnot Gneisses form an extensive layered sequence that crops out in southernmost Eyre Peninsula. They consist of garnetiferous quartzofeldspathic gneiss, hypersthene gneiss, granitic gneiss and basic granulite. Rb/Sr whole rock studies indicate a...

Radiocarbon dates from pedogenic carbonate are several thousand years too young, contrary to previous work, and are not reliable estimates of the age of pedogenesis.
