Australian magnetic observatories
Magnetic observatories capable of providing long-period results in absolute measures have been operated in Australia and its territories on and off since 1840. As the first such... -
Siderophile and lithophile trace-element evolution of the Archaean mantle
Progressive depletion of several Archaean volcanic sequences in siderophile (Fe, Ti, Mn, V), lithophile (Zr, Sr, P, Y), and chalcophile (Zn, Cu) elements with higher... -
Involvement of government organisations in geochemical surveys in Australia
A Workshop was held at the end of the 7th BMR Symposium in May 1978 on what the involvement of government organisations in Australia should be in geochemical surveys. This... -
Environmental and urban geology in Australia: workshop meeting of government...
Environmental and urban geology is an expanding field in which the government geological surveys are inevitably becoming more involved. Throughout the world, pressures for urban... -
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... -
Datasets for use with the Recharge-Discharge Estimator Suite spreadsheets
Determination of an accurate groundwater balance for a region requires estimation of recharge and discharge rates and, where possible, knowledge of their spatial distribution.... -
A geophysical profile across Australia at 29°S
Long wave-length components of the gravity and magnetic fields, topography, and heat-flow data, are examined along a trans-continent profile close to 29°S. The profile crosses... -
Geoscientific investigations from the Scott Plateau off northwest Australia...
In 1977 the R.V. Valdivia carried out a survey between Scott Plateau and the Java Trench, during which 1700 km of 24-channel seismic data, and 2550 km of bathymetric, gravity... -
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... -
Regional plate tectonics and the evolution of Australia's passive continental margins
The divergent, passive continental margins around Australia have evolved through the progressive dissection of eastern Gondwanaland in five separate seafloor-spreading episodes.... -
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°... -
Early Australian gravity observations
Since the publication of Gravimetry in Australia 1819-1976 (Dooley and Barlow, 1976), our attention has been drawn to the paper by Day (1966) on early Australian geophysical... -
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... -
Climatic corrections to Australian heat-flow data
Surface heating subsequent to Pleistocene glaciation in Australia has resulted in a decrease in near-surface thermal gradients. Heat flow in shallow holes therefore appears to... -
The gravity field of the Australian basement
The Australian gravity field is analysed to determine whether the basement differs between regions of exposed basement and of covered basement (sedimentary basins). When the... -
Computer manipulation of a Digital Terrain Model (DTM) of Australia
Images of the topography of Australia (DTM) have been created from a digital data file of about 320 000 topographic spot heights measured during the gravity survey of Australia,... -
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,... -
Determination of GDA94 coordinates for eight stations of Ultimate...
An application dated 30 May 2013 for verification of a reference standard of measurement under Regulation 12 of the National Measurement Regulations 1999 was received from... -
Implications of Australian seismic and gravity measurements for the...
In a previous paper densities of crustal layers were inferred from seismic refraction surveys in Australia and surrounding marine areas. These indicated substantial variations... -
On the isostatic compensation of Australia topography
The depth of isostatic compensation and the strength of the lithosphere are investigated by calculating isostatic anomalies for a range of isostatic models. The models are of...
