The Cretaceous of the Eromanga and Surat Basins
Little deformed Cretaceous sedimentary rocks underlie 1 500 000 km^2 of eastern Australia. Depositional environments in them range from freshwater to shallow marine. The... -
Effects of a major earthquake near Bougainville, 20 July 1975
On 20 July 1975 a major earthquake (MS7.9) shook the northern islands of the Solomon Islands chain. Damage amounting to at least $300,000 (Australian) occurred in the southern... -
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... -
The "Geera Clay equivalent": a regressive marine unit in the Renmark Group...
Sandy clays deposited during the waning phase of Oligocene-Middle Miocene transgression of the Murray Basin conformablyoverlie the shallow to marginal marine Geera Clay and... -
Structure and hydrocarbon potential of the Bremer Basin, southwest Australia
The Bremer Basin underlies part of the upper continental slope of offshore southwest Australia. It occupies an area of 9000 km2, and contains a sedimentary pile probably 10 km... -
Suspended-sediment transport and water movement at One Tree Reef, southern...
One Tree Reef, in the southern Great Barrier Reef, is roughly triangular, with the southeast corner forming the windward margin, and the northwest side the leeward margin. In... -
First record of Tethyan palynomorphs from the Late Triassic of East Antarctica
A well-preserved Late Triassic palynoflora from the upper Flagstone Bench Formation, Prince Charles Mountains, East Antarctica, contains taxa that are also widely distributed in... -
Palynology of Mesozoic dredge samples from the North West Shelf
Palynological examination was carried out on 34 sedimentary rock samples dredged from the offshore Rowley Terrace (Canning Basin), Scott and Exmouth Plateaux, and northern... -
Drowned dolines - the blue holes of the Pompey Reefs, Great Barrier Reef
Blue holes occur at Cockatoo and Molar Reefs, in the Pompey hard line reefs. These two holes are roughly circular in shape, between 240-295 m in diameter, and 30-40 m deep. They... -

Free-air anomaly and gravity maps of Australia - in colour, 1:25,000,000
On the following pages are a Free-air Anomaly Map of Australia and a Gravity Map of Australia (showing Bouguer anomalies on land and free-air anomalies at sea), both at a scale... -
Pattern of slow seafloor spreading (<4 mm/year) from breakup (96 Ma) to A20...
Australia separated from Antarctica by continental extension between the mid-Jurassic (>160 Ma) and mid-Cretaceous (96 Ma), then by slow seafloor spreading (half-rate <... -
Variation of crustal mass over the Australian region
Seismic refraction surveys in Australia and nearby marine areas provide data on crustal velocities and layer thicknesses. The averages of these at various places have been used... -
Structure and stratigraphy of the central Great Barrier Reef
The Cainozoic evolution of the central Great Barrier Reef Province has been deduced from shallow, intermediate, and deep focus seismic reflection profiling. For much of its... -
Archaeocyatha of the Amadeus and Georgina Basins
The Todd River Dolomite (Amadeus Basin) and Mount Baldwin Formation (Georgina Basin) are a part of the Early Cambrian platform cover of the central Australian craton. Marine... -
Implications of Australian seismic and gravity measurements for the...
In a previous paper densities of crustal layers were inferred from seismic refraction surveys in Australia and surrounding marine areas. These indicated substantial variations... -
Gravity provinces and their nomenclature
Gravity features have been defined and named by the various authors who have interpreted the results of land and marine reconnaissance gravity surveys in Australia. In general,... -
DISCUSSION: The elusive Cook volcano and other submarine forearc volcanoes...
Discussion: A recent paper (Ex on and Johnson, 1986) in this journal concluded that activity attributed in the past to the Cook submarine volcano, in the forearc region of the... -
Tectonic and metallogenic framework of the Cambrian Stansbury Basin -...
The Early to Middle Cambrian Stansbury Basin preserves a palaeogeographic zonation, from shallow shelf carbonates in the west (Spencer and Ardrossan Shelves) through extensional... -
