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... -
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... -
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... -
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... -
Planktonic foraminifera, age of sediments and polarity reversals, New...
Samples from the Rudiger Point-Cape Ruge area, New Britain, are not from a conformable late Miocene-earliest Pliocene sequence, as was presumed by previous workers, but rather... -
Regional variations in Australian heat flow
Twenty new heat-flow values from widely separated sites on the Australian continent are presented. These are combined with published land and marine data in the area 90-170°E,... -
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... -
Epeiric carbonate sedimentation of the Ninmaroo Formation (Upper...
The Ninmaroo Formation (Upper Cambrian-Lower Ordovician) is one of several epeiric carbonate sequences in the Georgina Basin. It comprises ooid, peloid, flat-pebble... -
Numerical techniques applied to the geochemistry of some estuarine sediments...
Q-mode factor analysis classified the estuarine samples from Broad Sound into two main geologically distinct groups representing intertidal and supratidal deposition. This... -
A reconnaissance investigation of the major Palaeozoic aquifers in the...
The Canning Basin is a large sedimentary basin with an onshore area of 430 000 km2. It has a thick, discontinuous succession of Palaeozoic and Mesozoic marine and continental... -
Stratigraphy and sedimentology of mid-Tertiary permeability barriers in the...
In the Murray Basin of southeastern Australia, the accelerated emergence of groundwater-related salinity problems in recent decades has led to the realisation that future... -
Compilation and production of the 1976 1:5 000 000 Gravity Map of Australia
In 1976 a coloured 1:5 000 000 Gravity Map of Australia was published by BMR. At that stage the systematic reconnaissance gravity coverage of Australia, initiated by BMR in... -
Drowned dolines - the blue holes of the Pompey Reefs, Great Barrier Reef
Blue holes occur at Cockatoo and Molar Reefs, in the Pompey hard line reefs. These two holes are roughly circular in shape, between 240-295 m in diameter, and 30-40 m deep. They... -
The ancient Murray River system
It has previously been suggested that an ancient Murray River once extended across the present line of the Mt Lofty Ranges, and emptied into Spencer Gulf. Evidence available... -
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... -
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... -
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... -
Aeolianites in the Jurassic Jurgurra Sandstone, Canning Basin, Western Australia
During the geological mapping of the Mount Anderson Sheet area of the Canning Basin in 1976, an exposure of the Jurassic Jurgurra Sandstone about 20 km north of the type... -
The determination of suspended-sediment loads in the southern Great Barrier...
A mechanical system for collecting samples of suspended sediment in the water column at various stages of a tidal cycle, together with measurement of tidal current velocities,... -
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...
