Paleogeothermal gradients in Australia: key to 4-D lithosphere mapping
Empirical paleogeotherms constructed from geothermobarometry of deep-seated xenoliths and garnet ± chromite concentrates from basalts, lamproites and kimberlites around... -
Fundamentals of airborne gamma-ray spectrometry
The interpretation of gamma-ray spectrometric data requires an understanding of the underlying physics of the method, and an insight into the data acquisition, system... -
Groundwater and surface water interaction at Lake George, New South Wales
Lake George is a fluctuating closed lake in the eastern highlands of Australia. Groundwater in the 932 km2 catchment is mainly of low salinity, but high salinity groundwater is... -
First record of shared species of Late Permian small foraminiferids in...
At least 12 species of small calcareous foraminiferids known from early Late Permian assemblages from Arctic Russia and adjacent areas also occur in assemblages from the eastern... -
Eastern Creek Volcanics: their geochemistry and possible role in copper...
New chemical analyses of relatively low-grade metabasalt from the Eastern Creek Volcanics, 120-150 km north of Mount Isa, Queensland, show them to be continental tholeiites. A... -
Conodont colour alteration adjacent to a volcanic plug, Canning Basin,...
The colour change of conodonts adjacent to a small volcanic plug in the Canning Basin, Western Australia suggests that the temperature of the liquid melt exceeded 600 °C. The... -
Seismic structure and continuity of the Redbank Thrust Zone, central Australia
The Redbank Thrust Zone in central Australia is a major Proterozoic Province boundary that was reactivated during the compressional Alice Springs Orogeny (300-400 Ma). To... -
Eocene and Oligocene calcareous nannofossils from the Great Australian...
Eocene and Oligocene assemblages identified from carbonates dredged from the outer margin of the Ceduna Terrace in the Great Australian Bight, southern Australia, document two... -
Evidence of an exhalative origin for deposits of the Cobar district, New South Wales
Evidence is presented to show that a strong mineralogical/chemical zoning exists in seven deposits of the Cobar-Nymagee area. Characteristically, the within-deposit zoning,... -
Glacial-interglacial paleoceanography from Australian margin sediments:...
The Australian Geological Survey Organisation has collected cores from two areas of the Australian continental margin- the Exmouth Plateau and Perth Basin (EP/PB) in the... -

The continent/island-arc collision in northern Papua New Guinea
Recent geological mapping in the north coast ranges of Papua New Guinea has recognised a Paleogene island arc. This arc is believed to have faced southward, and formed at the... -
The stratigraphic sequence of old land surfaces in northern Queensland
In northern Queensland there are several old land surfaces which are related to previous periods of erosional and depositional activity. The surfaces are of two main types -... -
McArthur Basin, Northern Territory: mapping of deep troughs using gravity...
Published models for the Proterozoic McArthur Basin show up to 4 km of sedimentary cover over widespread shelves, and a 50-80 km wide by 600 km long, central meridional half-... -
The petrology, geochemistry and implications of basalts dredged from the...
We report major and trace-e lement compositions of 14 basalts and dolerites dredged from seven sites along the outer rifted margin of northwestern Australia. Lavas from the... -
Management of saltwater intrusion in coastal aquifers in Queensland, Australia
Many Queensland rivers have extensive deltas, which have large reserves of groundwater. These deltas contain fertile land suitable for intense agricultural development with... -
Brachiopods from the Silurian of Fyshwick, Canberra, Australia
Ten species of articulate brachiopods are described from the Silurian (Wenlock) Canberra Formation of Fyshwick, Canberra. One, Leploslrophia (Leplostrophiella) oepiki, is new... -
Analysis of continental structures using a Digital Terrain Model (DTM) of Australia
Colour images of the topography of Australia, generated and manipulated by computer techniques, have been used for analysis of regional geological structures. Discussion is... -
Shallow inter-reefal structure of the Capricorn group, southern Great Barrier Reef
276 km of continuous seismic reflection profiles have been obtained from the inter-reef areas of the Capricorn Reefs. Five reflectors were identified, three being widespread:... -
New occurrences of phyllolepid placoderms from the Devonian of central Australia
The first well-preserved bones of phyllolepid placoderms from the Devonian of central Australia are described from the Deering Hills and Waterhouse Range in the Amadeus Basin,...
