Australian gravity base-station network: 1980 survey
In 1980, a gravity base-station network of 67 airports throughout Australia was surveyed with seven LaCoste and Romberg gravity meters, and tied to sites of six 1979 absolute... -
Palaeo- and Mesoproterozoic mineral deposits in Queensland
Proterozoic rocks crop out in northwest and far north Queensland. The Mount Isa Inlier, in the northwest, is a major producer of silver, lead, zinc and copper, and a small... -
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... -
Geochemistry and tectonic significance of Proterozoic mafic rocks from the...
Mafic igneous rocks were emplaced during deposition of the Robertson River Subgroup, part of the early or Middle Proterozoic Etheridge Group in the Georgetown Inlier. They... -
The hydrogeochemistry of groundwater in fractured bedrock aquifers beneath...
Fresh to brackish groundwaters in the range of 250 to 2250 mglL occur in fractured bedrock aquifers beneath dryland salinity sites at Yass in the Southern Tablelands of New... -
Explosion seismic profiles, and implications for crustal evolution, in...
The interpreted velocity-depth structure in the crust of the Lachlan Fold Belt in southeastern Australia indicates that velocity gradients, rather than discontinuous velocity... -
Calcareous nannofossils from the Toolebuc Formation, Eromanga Basin, Australia
Calcareous nannofossils in the Toolebuc Formation reference section and in the lowermost Allaru Mudstone in BMR Boulia 3 suggest a middle to late Albian age. The evidence... -
Prograde and retrograde sapphirine in metamorphic rocks of the central...
Sapphirine is a common mineral in silica-undersaturated rocks within the Mid-Proterozoic granulites of the Arunta Block in the northern Strangways Range, central Australia, and... -
Hot-spot volcanism in St Andrew Strait, Papua New Guinea: geochemistry of a...
Four distinct volcanic rock types are found above a conjectured mantle hot spot in St Andrew Strait, northern Papua New Guinea. Hypersthene-normative basalts on Baluan Island... -

The age of the diamond-bearing pipes and associated leucite lamproites of...
New K-Ar and Rb-Sr ages obtained for 14 separate lamproite intrusions in the Fitzroy area of the West Kimberley region of Western Australia confirm the early Miocene ages... -
What maps are needed now?
A panel discussion was held during the Sixth BMR Symposium in Canberra in May 1977, on what earth-science maps are needed now in Australia. This account gives background... -
A new lithostratigraphic framework for the Early Jurassic units in the...
Recent detailed studies of key transects throughout the Clarence-Moreton Basin have shown that a revision of nomenclature is required for units in the Late Triassic to Early... -
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... -
Delny-Mount Sainthill Fault System, eastern Arunta Block, Central Australia
The Delny-Mount Sainthill Fault System, a distinctive feature on satellite photographs, can be traced as a well-developed geological and geophysical feature extending some 130... -
Hydrogeochemical zonation of groundwater in the Botany Sands aquifer, Sydney
The groundwater quality in the Botany Sands aquifer has deteriorated in the last 50 years due to contamination associated with industrial developments, urbanisation and over-... -
Planorbulinella solida sp.nov. (foraminiferida) from the Miocene of Papua New Guinea
Specimens from the Miocene of Papua New Guinea previously identified as Linderina sp. indet. are described as Planorbulinella solida sp. nov., which is widespread in beds of... -
Reconnaissance of upper crustal seismic velocities in the Tennant Creek...
Upper crustal seismic investigations of the Tennant Creek Block indicate that the Warramunga Group rocks have P-wave velocities of 5.22-5.55 km/s (average 5.42 km/s) and S-wave...
