The Early Cretaceous non-marine volcaniclastic Eumeralla Formation accumulated in a rift basin on the southern margin of Australia during the break-up of eastern Gondwana.... -
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... -
The Maastrichtian and early Tertiary record of the Great Australian Bight...
Samples dredged during BMR Survey 66 by KV, Rig Seismic in the central Great Australian Bight Basin are examined and their calcareous nannofossils are recorded. The... -
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 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... -
Gravimetry in Australia, 1819-1976
The earliest known gravity measurements in Australia were made by French expeditions in 1819 and 1824, using pendulums at Sydney. Later in the 19th century, further pendulum... -
Source rock potential and hydrocarbon prospectivity of the Darling Basin, NSW
Available geological and geophysical data for the dominantly Devonian Darling Basin of western New South Wales indicate a high risk for petroleum exploration. Hydrocarbon... -
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... -
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... -
Sequence stratigraphy: a review of fundamental concepts and their...
Sequence stratigraphic concepts and techniques provide a powerful tool to analyse and predict stratal architecture and facies patterns within sedimentary basins. The concepts... -
Buried reef structures in the Lennard Shelf, Canning Basin, Western Australia
Buried Upper Devonian reef has been found in Meda No. 1 borehole in the Lennard Shelf, Canning Basin. Frequency analysis made on seismic-record sections across the structure... -
Manganese nodules from the Tasman Sea off Sydney
Two manganese nodules were recently recovered by HMAS Kimbla from a water depth of 4300 m, in a northeast-trending trough about 250 nautical miles southeast of Sydney (155°... -
Proterozoic microfossils from the Roper Group, Northern Territory, Australia
The Roper Group (minimum age approximately 1300 x 10^6yr) is a shallow water sequence of sandstone, siltstone, and shale, with minor, sub-economic oolitic ironstone. The... -
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 <... -
Early Devonian thelodonts (Agnatha) from the Toko Syncline, western...
Thelodont scales recovered from the basal (calcareous) unit of the Cravens Peak Beds in the Georgina Basin, are referable to Turinia australiensis Gross, 1971, T. cf. pagei... -
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... -
Late quaternary regional controls on the development of the Great Barrier...
High-resolution seismic reflection data have been examined in an attempt to identify and explain some of the regional differences and controls on the development of the Great... -
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... -
Geology and offshore petroleum prospects of the eastern New Ireland Basin,...
The eastern part of the New Ireland Basin of Papua New Guinea is about 600 km long by 150 km wide and mostly offshore, northeast of New Hanover and New Ireland. Basin geology... -
