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... -
The evolution of One Tree Reef, Southern Great Barrier Reef, Queensland
One Tree Reef is one of fourteen reefs in the Capricorn Group, southern Great Barrier Reef. The reef has an asymmetrical triangular shape, 5.5 km long and 3 km wide, with a... -
Mesozoic outcrops on the lower continental slope off Exmouth, Western Australia
Seismic reflection profiles over the southwestern margin of the Exmouth Plateau, which have been tentatively tied to the Northwest Shelf stratigraphic sequence, indicate that... -
Preliminary studies of the Cape Leeuwin manganese nodule deposit off Western...
In 1970 a large deposit of ferromanganese nodules was discovered on the floor of the Indian Ocean southwest of Cape Leeuwin by the research vessel USNS Eltanin. This discovery,... -
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... -
Structure and tectonic history of the northern Exmouth Plateau and Rowley...
A series of regional seismic reflection lines has been recorded, which link three key exploration wells on the northern Exmouth Plateau and Rowley Terrace to the lower... -
Sequence analysis and depositional models of crinoidal limestones, Permian...
The Permian Yessabah Limestone, a thick crinoidal limestone unit, appears abruptly in the stratigraphic succession over a large area of the Hastings Block in northeastern New... -
Submarine valleys on the Ceduna Terrace off South Australia
A detailed bathymetric map has been compiled for the Ceduna Terrace, off South Australia. The most striking features of the bathymetry are numerous submarine valleys, which... -
Origins of sulphide in sediments
Sulphide in sedimentary ore deposits may be derived directly from the mantle or by reduction of sulphate. Sulphide in modem hydrothermal deposits is thought to have formed... -
Geoscientific investigations from the Scott Plateau off northwest Australia...
In 1977 the R.V. Valdivia carried out a survey between Scott Plateau and the Java Trench, during which 1700 km of 24-channel seismic data, and 2550 km of bathymetric, gravity... -
Seismic refraction - a tool for studying coral reef growth
Seismic refraction studies have been conducted in close proximity to shallow boreholes previously drilled at Bewick (Northern Great Barrier Reef), Hayman (Central Great Barrier... -
Diagenetic organic matter in Recent sediments and environments of deposition
Organic geochemical studies of the reduced organic material in sedimentary rocks provide a valuable insight into the origin and history of the sediments. Information on the... -

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... -
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... -

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... -
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... -
Stable isotope and chemical studies of volcanic exhalations and thermal...
Thermal waters in Matupi Harbour and Sulphur Creek, Rabaul caldera have D/H and O18/O16 ratios that are indicative of a mixed source. They are the result of mixing of local... -
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...
