Guide covers an area extending from the western margin of Lake Torrens to Coober Pedy, and down to Ceduna. Characteristics of the silcretes in the Tertiary sequences, field relationships, and other criteria which might be used to interpret processes...

Agate or banded chert nodules weather out of the Cambrian Andamooka Limestone over an area of several square kilometres south of the Stuart Creek Opal field. In places the agate nodules are concentrated into extensive deflation lag gravels. Banding is...

The Benagerie Ridge is a basement high which has been actively shedding detritus since Adelaidean times. It includes porphyry, with thin cover of Adelaidean rocks, flanked by Cambrian and possible Adelaidean sediments. The Cainozoic blankets the...

205 auger holes up to 9 metres deep indicate the bulk of the reserves without beneficiation are suitable for agriculture. Reserves of 149 000 tonnes of high grade seed gypsum, suitable for cement and plaster manufacture near present mining...

Following the drying of the very extensive Tertiary lakes, there were 3 complex Pleistocene climatic cycles, or portions thereof, reflecting changes in the world climate related to glacial / interglacial episodes. Describes and interprets 4...

This SADME stratigraphic drillhole has intersected high grade Precambrian basement gneisses at 691.33 metres depth below a sequence of unmetamorphosed arenaceous and rudaceous sediments of the ?Cambrian Murnaroo Sandstone. Evidence from the clasts in...

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...

Colour variation was ascribed to the dominance of limonite coatings on sand grains, to uncoated grains and to various proportions of clay.

Nuclear weapons tests and related minor trials conducted in Australia by the British Government between 1952 and 1963, are summarised. The possible effects on test personnel and civilians which could be caused by radiation and fallout, the situation...

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...

Twenty four water wells were drilled, and three existing water wells cleaned out, in the North-West Aboriginal Reserves during 1978. Sixteen of the new wells were successful in obtaining a groundwater supply suitable for their specified use, which was...

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...

A system of parallel arcuate ridges dominates the topography of the Billa Kalina area; facies relationships indicate that they are silicified strandlines of a Miocene lake which have been etched out by later erosion. Clays and dolomites of the Miocene...

This report concerns the stratigraphic setting and palaeontology of nonmarine Mollusca to complement continuing investigations by R. A. Callen in Lake Frome and southern Strzelecki Desert, and to provide supporting data on palaeoecology and...

A shallow test hole was drilled near Cape Northumberland to check the feasibility of tunnelling through the Gambier Limestone beneath the sea bed. The drilling showed widespread flint throughout the limestone, and comparison with nearby outcrop...

Drilling and testing of well HDO22 to 26 metres has confirmed relationship between high transmissivity and low hydraulic gradient within the basin.

Byilkaoora 1, a stratigraphic well drilled in the northeastern part of the Officer Basin in South Australia, intersected aeolian and fluvial sandstones and mudstones overlying 224 m of fine-grained, dolomitic, calcareous and argillaceous sediments...

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.

A study has been carried out to determine the cause of declining water levels in wells for irrigation, stock and domestic supplies. The study commenced in 19/1 and has involved field surveys, the establishment of a network of observation wells and the...
