Some aspects of interstitial water movements in simulated sedimentary systems
Biological and abiological factors influencing interstitial water movements in sediments were studied in a simulated system. The porosity and permeability of the system... -
A teleseismic travel time residual map of the Australian continent
Teleseismic travel time residuals for 43 seismic observatories and 6 networks of portable seismographs have been combined to produce a contour map of residuals for the... -
The differential weathering of granitic rocks in Victoria, Australia
Landscape features such as positive relief and negative relief plutons and stepped topography are a result of differential weathering of granites. Features of the granitic... -
Practical uses of chemical modelling-defining new exploration targets in...
Numerical simulations of geochemical processes can help in the design of exploration programs for a variety of geological environments. Chemical modelling can be used to predict... -
BMRs legacy and AGSOs mission: strategic influences on the future direction...
Rapid changes in the operating environment for national geological surveys are forcing an almost constant re-evaluation of their role and the Australian Geological Survey... -
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... -
Nannofossil biostratigraphy of the Hantkenina (foraminiferid) interval in...
Based on calcareous nannofossil evidence, the stratigraphically important interval with Hantkenina (H.) alabamensis primitiva Cushman and Jarvis in the upper Eocene of southern... -
A century of earthquakes in the Dalton-Gunning region of New South Wales
The Dalton-Gunning region of New South Wales (34.5-35.0oS, 148.5- 149.5°E) is one of the more seismically active areas in Australia. Reports of felt earthquakes which occurred... -

Behaviour of aluminium and iron in acid runoff from acid sulphate soils in...
Aluminium and iron concentrations and partitioning between particulate, colloidal and dissolved forms were examined in acid run-off from known acid sulphate soil environments in... -
The discovery of Miocene vertebrates, Lake Frome area, South Australia
This report announces the discovery of a diverse vertebrate fauna from exposures of the Namba Formation in the southern Frome Embayment (Tarkarooloo Basin), South Australia. The... -
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... -
Architecture and evolution of the Australian continental margin
Interpretation of key seismic profiles around the Australian margin clearly show that the three principal rift-drift segments (north-western/western, southern, and eastern) have... -
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... -
The Australian National Gravity Database
AGSOs Australian National Gravity Database contains data from more than 900 000 point gravity observations on the Australian mainland, over the continental margins, on the... -
Growth fabrics and growth rates of Holocene reefs in the Great Barrier Reef
Over the past five years, scientists of the Bureau of Mineral Resources and James Cook University of North Queensland have drilled 61 holes into 24 reefs throughout the Great... -
Application of sequence stratigraphic concepts to Middle Cambrian...
The stratigraphic and spatial distributions of phosphatic and organic-matter rich Middle Cambrian sediments of the Georgina Basin are outlined in terms of sequence stratigraphic... -
Deep-water Quaternary Foraminifera from short cores taken between Australia...
Twenty short cores were recovered from the northern Scott Plateau (water depths ca 3200 m) and the southern slope of the Java Trench (water depths 4950-5790 m) by R.V. Valdivia...
