Oldest Cretaceous sequence, Giralia Anticline, Carnarvon Basin, Western...
Outcrop of the oldest Cretaceous sequence in the Giralia Anticline and the Giralia No. 1 well, penetrating the same sequence, are described and biostratigraphically assessed in... -
Miocene to Pleistocene foraminiferal biostratigraphy of dredge samples from...
Planktic and larger benthic foraminiferids have been studied in thin section from a suite of dredge samples of two sites on the Marion Plateau, offshore Queensland. The two... -
Nannofossil and planktic foraminiferal biostratigraphy around the...
Nannofossil evidence suggests that the up-sequence appearance of Globigerinoides quadrilobatus primordius is depth-related, and first occurs at a lower stratigraphic level in... -
The Great Artesian Basin, Australia
The Great Artesian Basin occupies 1.7 X 10^6 km^2, or about one-fifth of Australia, extending across parts of Queensland, New South Wales, South Australia, and the Northern... -
Global sea-level change as a method of correlating the Late Permian coal...
Eustatic changes in sea level can be used to correlate sequences in widely separated areas. Thick terrestrial sequences with marine intercalations are especially suitable,... -
Geological evolution, tectonic style, and economic potential of the lawn...
The Lawn Hill Platform Cover comprises a sequence of mildly deformed Proterozoic sediments and volcanics that crop out northwest of Mount Isa. Three subdivisions are recognised... -
Evidence of an exhalative origin for deposits of the Cobar district, New South Wales
Evidence is presented to show that a strong mineralogical/chemical zoning exists in seven deposits of the Cobar-Nymagee area. Characteristically, the within-deposit zoning,... -
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... -
Geological note: Igneous and sedimentary rocks dredged from the northern...
Altered basalt, dolerite and gabbro have been dredged from a previously unsampled portion of the Macquarie Ridge (47o-48° S), using the commercial fishing vessel Amaltal... -
Late Cambrian trilobites from the Mariner Group, northern Victoria Land, Antarctica
This paper describes the youngest Late Cambrian trilobite assemblage so far discovered in the Mariner Group (Bowers Supergroup) northern Victoria Land, Antarctica. It occurs... -
The sediments of the Argo Abyssal Plain and adjacent areas, northeast Indian Ocean
A series of geophysical traverses by the Atlantis II across the Argo Abyssal Plain, together with coring at a number of selected localities has provided new information on... -
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... -
The geochemistry of Lake Frome, a playa lake in South Australia
Lake Frome, a large playa in southeast South Australia, lies at the centre of an internal drainage basin. Sediments and brines in the lake were studied to determine if the... -
Lord Howe Rise, Tasman Sea - preliminary geophysical results and petroleum prospects
The Lord Howe Rise is a major submarine feature in the Tasman Sea; it extends northwest from the New Zealand continental margin and lies about 600 to 1200 km off the east coast... -
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... -
Late Cretaceous-Palaeogene nannofossil biostratigraphy of Challenger No. 1...
Late Cretaceous-Palaeogene calcareous nannofossil assemblages from the mainly carbonate section in Challenger No. 1 well, above the 780m level, have some similarities with the... -
Glacial-interglacial paleoceanography from Australian margin sediments:...
The Australian Geological Survey Organisation has collected cores from two areas of the Australian continental margin- the Exmouth Plateau and Perth Basin (EP/PB) in the... -
The nature and origin of beach ridges, western Cape York Peninsula, Queensland
Two sets of beach ridges are known from the western side of Cape York Peninsula. The older set are thought to be late Pleistocene. They rest on a basement of older fan deposits... -
The hydrogeochemistry of groundwater in fractured bedrock aquifers beneath...
Fresh to brackish groundwaters in the range of 250 to 2250 mglL occur in fractured bedrock aquifers beneath dryland salinity sites at Yass in the Southern Tablelands of New... -
Thick ferromanganese deposits from the Dampier Ridge and the Lord Howe Rise...
Chemical and mineralogical data are presented for four ferromanganese samples (two nodules and two crusts) from two stations of the West German vessel Sonne. Three samples came...
