Content: 1.Blake DH, Hoatson DM. Granite, gabbro, and migmatite field relationships in the Proterozoic Lamboo Complex of the East Kimberley region, Western Australia. 2.Black... -
Interactions between saline redbed groundwaters and peritidal carbonates,...
A commonly cited model for the genesis of stratiform Cu deposits that lack either igneous or hydrothermal associations has been tested in modern environments, on 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... -
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 late Cainozoic sequence of southeast South Australia and Pleistocene...
A recent drilling program in southeast South Australia has provided new insight into the late Cainozoic sequence of that area. Uplift of the region occurred during the... -
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... -
Upper Cambrian (Mindyallan) trilobites and stratigraphy of the Kayrunnera...
Nine species of trilobites are recorded from three localities within a restricted stratigraphic interval near the base of the newly defined Kayrunnera Group (previously... -
Pleistocene to Holocene planktic foraminiferal biostratigraphy of the Coral...
Fifteen of 27 potential planktic foraminiferal biostratigraphic events from the latest Pliocene-Holocene have been examined; most of the early Pleistocene was not able to be... -
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,... -
Impact of runoff on nutrient patterns in northern Port Phillip Bay, Victoria
As part of the Port Phillip Bay Environmental Study, bay-wide nutrient (ammonium, nitrate, nitrite, phosphate, silicate) and chlorophyll a distributions were measured at monthly... -
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 <... -
Long-term landscape evolution on Groote Eylandt, Northern Territory
Like other areas throughout the north of the Northern Territory, Groote Eylandt is dominated by a landscape of great age. Previous interpretations have argued that this... -
Relative fall of Holocene sea level and coastal progradation, northeastern...
The levels of intertidal environments of prograding Holocene coastal complexes of northeast Spencer Gulf have been precisely measured and their relation with the tidal range... -
Chemistry of manganese nodules from the Cape Leeuwin field off Western Australia
A preliminary report on the manganese nodule field southwest of Western Australia published in this Journal recently (Frakes, Exon and Granath, 1977) quoted chemical analyses... -
Methane anomalies in seawaters of the Ragay Gulf, Philippines: methane...
The vertical distribution of methane has been measured in the water column of a semi-enclosed basin, the Ragay Gulf, in the Philippines archipelago. The methane distribution is... -
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... -
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... -
The gravity field of offshore Australia
The free-air anomaly field of offshore Australia has been divided into about fifty regional gravity provinces, each of which is characterized by uniformity of trend, free-air...
