Western Australia onshore plus marine magnetic grid geodetic
Total magnetic intensity (TMI) data measures variations in the intensity of the Earth's magnetic field caused by the contrasting content of rock-forming minerals in the Earth... -
A non-marine Lower Cretaceous rift-related epicIastic volcanic unit in...
Relationships, thicknesses, and palaeocurrent and other sedimentary data applying to facies associations in Eumeralla Formation outcrops in the eastern Otway Basin distinguish... -
Glacially grooved surfaces in the Grant Group, Grant Range, Canning Basin...
Grooved surfaces in Late Palaeozoic Grant Group rocks in the central Grant Range were cut by glacial ice. The orientation of the grooves and small step-like sedimentary... -
Geology of the Exmouth and Wallaby Plateaus off northwest Australia:...
In this paper we present the first detailed geological information about the margins of the Exmouth and Wallaby Plateaus. New single-channel seismic profiles helped to select... -
Western Australia: Phanerozoic geology and mineral resources
Phanerozoic rocks in onshore Western Australia are primarily sedimentary. Volcanic and intrusive rocks are known from only a few areas and are mostly related to continental... -
Tectonic and sedimentary history of the Argo Abyssal Plain, eastern Indian Ocean
Bathymetric and seismic reflection profiles totalling about 2800 km, and covering about 110 000 km2 of the Argo Abyssal plain, have been analysed. The early emplacement of... -
Triassic environments in the Canning Basin, Western Australia
A review of the lithology, sedimentary structures and palaeontology, supplemented by original investigations, suggests that the Triassic system in the Canning Basin can be... -
Videos and images from SOL5117 (Joseph Bonaparte Gulf)
The Joseph Bonaparte Gulf survey (SOL5117, GA survey #0325) was conducted on the R.V. Solander between 30 July and 30 September 2010 in collaboration with staff from the... -
Quaternary and modern environments of the Van Diemen Rise, Timor Sea, and...
Environmental baseline data are required for Australias offshore areas before petroleum exploration. This has boosted demand for analysis and interpretation of the Quaternary... -
Geological history of the outer North West Shelf of Australia: a synthesis
This paper uses information contained in other papers in this issue of the AGSO Journal together with the scientific literature to produce a synthesis of the geological... -
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... -
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,... -
Significance of calcareous nannofossil-bearing Jurassic and Cretaceous...
Examination of dredge hauls taken from the Rowley Terrace, northwest Australia, has revealed the occurrence of several Mesozoic nannofossil-bearing levels. Dating has been... -
Stratigraphy and palynology of Mesozoic sediments from the Great Australian...
The offshore Mesozoic Bight and Duntroon Basins formed through rifting and separation of the Australian and Antarctic plates. Palynological investigation of samples dredged from... -
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... -
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... -
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... -
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... -
Mesozoic sedimentary and volcanic rocks dredged from the northern Exmouth...
The deeply incised northern margin of the Exmouth Plateau has been dredged extensively along seismic reflection profiles, in water 2000- 5600 m deep, by R. V. Sonne (Cruise...
