Proterozoic microfossils from the Roper Group, Northern Territory, Australia
The Roper Group (minimum age approximately 1300 x 10^6yr) is a shallow water sequence of sandstone, siltstone, and shale, with minor, sub-economic oolitic ironstone. The... -
Australian Mineral Exploration: analysis and implications
Australian mineral exploration is at a 20 year low in real terms. After doubling in line with global exploration activity during the 1990s, exploration expenditure peaked in... -
An instrument for simultaneous measurement of Eh and pH in boreholes
An instrument is described that measures Eh and pH simultaneously in boreholes. The temperature of the borehole fluid and its self-potential with respect to an up-hole mud probe... -
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... -
Sequence stratigraphy: a review of fundamental concepts and their...
Sequence stratigraphic concepts and techniques provide a powerful tool to analyse and predict stratal architecture and facies patterns within sedimentary basins. The concepts... -
Ages of granites and associated mineralisation in the Herberton tinfield of...
Rb-Sr isotopic data reveal a close temporal association between ore deposits and the emplacement of Upper Palaeozoic granitic intrusions in the Herberton tinfield of northeast... -
Aspects of landscape history and regolith in the Kalgoorlie region, Western Australia
The regolith of the Kalgoorlie region includes saprolite in deep weathering profiles, and a range of surficial deposits, including colluvium, alluvium, and duricrusts, the... -
Potential from enhanced oil recovery applications in Australia
As a result of a Society of Petroleum Engineers/National Energy Research Demonstration and Development Council (NERDDC) meeting in Adelaide in April 1986 between Australian oil... -
Magnetic responses associated with mineral deposits
Systematic associations of magnetic minerals occur in many mineral deposits and, consequently, the probable presence of mineral deposits can be deduced from anomaly patterns in... -
Youngest Permian marine macrofossil fauna from the Bowen and Sydney Basins,...
The marine invertebrate macrofauna from the upper part of the Blenheim Subgroup of the Bowen Basin and the Kulnura Marine Tongue of the Sydney Basin is described. The fauna is... -
Flushing of Australian estuaries, coastal lakes and embayments: an overview...
Examination of a simple, but quantitative parameter, Sf/So, the ratio of average salinity of a coastal waterway/marine source water salinity, both geographically and temporally,... -
The Early to Late Proterozoic Broken Hill Province, New South Wales
The Broken Hill Province is best known for the Broken Hill orebody, originally containing about 300 million tonnes of economic and sub economic Pb- Zn- Ag mineralisation, and... -
A belemnite biozonation for the Jurassic-Cretaceous of Papua New Guinea and...
Middle and Late Jurassic and some Early Cretaceous Belemnitida collected mostly within the region covered by the Ok Tedi and Mianmin 1:250 000 sheets in the central highlands of... -
The problem of inconsistency between thermal maturity indicators used for...
A major frustration in thermal maturation modelling for petroleum exploration in Australian sedimentary basins is the inconsistency between the values of different thermal... -
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... -
Ordovician nautiloids of central Australia, with a revision of Madiganella...
Nautiloids mainly from the Lower Ordovician Horn Valley Siltstone of the Amadeus Basin are revised. Madiganella is shown to have unexpanded two-layered bullettes and well-... -
Conodont apparatuses in an Upper Devonian palaeoniscoid fish from the...
Conodont elements recovered from the gut region of a palaeoniscoid fish from the Gogo Formation, Upper Devonian (Frasnian), of the Canning Basin, Western Australia, are assigned... -
Mineralogy and chemistry of weathered and parent sedimentary rocks in...
Weathered profiles and parent rocks in the Queensland part of the Eromanga Basin were investigated using geochemical and clay mineral techniques. Approximately 170 rock samples...
