A crustal profile across the Archaean Pilbara and northern Yilgarn cratons,...
Two Archaean cratons are exposed in the Precambrian shield of Western Australia: the Pilbara in the north and the Yilgarn in the south. They are separated by the Capricorn... -
Stratigraphy and sedimentology of Late Palaeozoic glaciomarine sediments...
Sediments of the Late Palaeozoic Urana Formation in infrabasins beneath the Cainozoic Murray Basin include glaciomarine diamictite, fine-grained sediment, sandstone, and... -
A Rb-Sr geochronological study in the Proterozoic Tennant Creek Block,...
Rb-Sr isotopic data from total rock and mineral samples provide a broader geochronological framework than has hitherto been available for the Proterozoic rocks of the Tennant... -

Mesozoic Bivalvia from Clerke and Mermaid Canyons, northwest Australian...
Four sets of rock samples from two sites off the northwest Australian shelf in 3625-4480 m of water contain macrofaunas, mainly bivalves, of warm shallow-water origin. Mermaid... -
A regional review of the geological sources of magnetic and gravity anomaly...
Regional airborne magnetic and gravity data and field observations have been used to define four geophysical domains in the Lachlan Fold Belt of New South Wales. Each has a... -
The age of the Mud Tank Carbonatite, Strangways Range, Northern Territory
Dates of 732 ± 5 m.y. (U-Pb zircon) and 735 ± 75 m.y. (Rb-Sr total rock) define the crystallisation age, and possibly also the emplacement age, of the Mud Tank Carbonatite.... -
A pygmy cassowary (Casuarius lydekkeri) from late Pleistocene bog deposits...
Bones of a tiny cassowary from late Pleistocene bog deposits in the Southern Highlands of New Guinea are indistinguishable from bones of Casuarius lydekkeri of unknown... -

Rb-Sr geochronology of Proterozoic events in the Arunta Inlier, Central Australia
Rb-Sr data reveal a long and complex Proterozoic history for the Arunta Inlier of central Australia. The first event was a widespread, dominantly granulite-facies episode, known... -

Airborne magnetic and gamm-ray data acquisition
Current aeromagnetic data acquisition has benefited from improvements in measurement precision and compensation systems for removing the magnetic effects of survey aircraft. GPS... -
A review of the Grenville orogen in its North American type area
In a reconstructed supercontinent assembly at ~0.9 Ga, the Grenville orogen extends from Scandinavia through North America and Antarctica to Australia. Part of it, the 2000 km... -
Spectral representation of isostatic models
The development of cross-spectral techniques for investigating the relation between gravity and topography has led to the representation of isostatic processes in terms of... -
Holocene Palaeo-Environmental changes, central to north Great Barrier Reef inner zone
Fringing reefs and storm ridges, from inner-shelf sites on the Great Barrier Reef between 14° and 20° S, are examined for Holocene sea-level and climatic changes. The sites... -
Mapping 137Cs at Maralinga nuclear test site, South Australia, using...
We have developed a simple method for separating the gamma radiation due to 137Cs from that due to natural sources using conventional 4-channel airborne gamma-ray spectrometry.... -
Discrimination of surficial and bedrock magnetic sources in the Cobar area, NSW
Known mineral deposits in the Cobar area of NSW are magnetic. Hence, the magnetic method is an important tool in the search for mineral deposits in this area. Unfortunately,... -
Crustal structure of the southern McArthur Basin, Northern Australia, from...
Deep seismic refraction and vertical reflection recordings have been made in the southern McArthur Basin, over the Bauhinia Shelf and Batten Trough between Daly Waters and the H...
