A field classification and intensity scale for first-generation cleavages
The chief morphological characteristics and lithological associations of naturally occurring cleavage fabrics are reviewed with the aim of differentiating qualities that... -
Early geophysical practice - the BMR instrument collection
The Bureau of Mineral Resources, Geology and Geophysics was formed in 1946. It replaced the Mineral Resources Survey (1942-46) whose forerunners were the Aerial Geological and... -
New microform publications
BMR has decided that future issues in its Report series will be on microfiche. A hard-copy contents listing, and abstract, will accompany each Report. Summaries of the first... -
Thick ferromanganese deposits from the Dampier Ridge and the Lord Howe Rise...
Chemical and mineralogical data are presented for four ferromanganese samples (two nodules and two crusts) from two stations of the West German vessel Sonne. Three samples came... -

The early geological history of the Proterozoic Mount Isa Inlier,...
Not surprisingly, Derrick and Wilson find much to disagree with in the interpretation of the geological history of the Mount Isa Inlier proposed in my paper (Blake, 1980). Most... -

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...
