Current models for metamorphic fluid flow provide a framework for understanding the setting and genesis of Australian Precambrian ore deposits thought to have formed during... -
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°... -
Origins of groundwater salinity near Tresco, northwest Victoria
Core samples and groundwater from bores at Tresco, northern Victoria, in the southern margin of the Murray Basin, have been analysed for palynology and chemistry. An aquifer... -

The hydrogeology of the Murray Basin, southeastern Australia
Soil degradation is the most serious environmental issue facing Australia today, and a major problem is the land salinisation and degradation of surface water quality in the... -
Thermal history of the Gosses Bluff impact structure, central Australia,...
Gosses Bluff is the remnant of a latest Jurassic asteroid or comet impact structure in the Amadeus Basin, central Australia. Conodonts have been successfully extracted from... -
Emplacement ages of granitic rocks in the Coen Inlier (Cape York):...
New zircon ion-microprobe U-Pb analyses define two major, short-lived episodes of Palaeozoic magmatism within the Coen Inlier, north Queensland. The younger occurred at about... -
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... -
Australian long-wavelength magnetic anomalies
A long-wavelength magnetic anomaly map is derived from near-surface observations. The data can be continued upward for comparison with maps derived from satellite data. Compared... -

Palynostratigraphy of the Bookpurnong Beds and related Late Miocene-Early...
Dinoflagellates offer a reliable method for distinguishing the Late Miocene-Early Pliocene Bookpurnong beds from lithologically similar marginal marine sediments, such as the... -
A model for sulphide band formation under epigenetic conditions - a study...
The formation of sulfide bands in sediments has been investigated in the past, but in all the cases described they have formed by the diffusion of solutes from stationary fluids... -
Aquifer vulnerability on small volcanic islands in the southwest Pacific...
Island ecosystems in the southwest Pacific region are noted for their fragility and susceptibility to degradation, particularly in regard to groundwater systems. In general,... -
Evan Richard Stanley, 1885-1924: pioneer geologist in Papua New Guinea
Evan Richard Stanley was the first Government Geologist for Papua, from 1911 to 1924. Under difficult conditions, he conducted geological investigations that resulted in more... -
The late Cainozoic evolution of the Carpentaria Plains, North Queensland
The Pliocene to Holocene fluvial sediments of the Carpentaria Plains southeast of the Gulf of Carpentaria, Queensland have formed sandy and silty plains in fan settings to the... -
Origins of sulphide in sediments
Sulphide in sedimentary ore deposits may be derived directly from the mantle or by reduction of sulphate. Sulphide in modem hydrothermal deposits is thought to have formed... -
