Lord Howe Rise, Tasman Sea - preliminary geophysical results and petroleum prospects
The Lord Howe Rise is a major submarine feature in the Tasman Sea; it extends northwest from the New Zealand continental margin and lies about 600 to 1200 km off the east coast... -
Geology and mineralisation of the Arunta Inlier, Northern Territory
The Arunta Inlier forms an extensive Proterozoic terrain in central Australia. It occupies an area of 200 000 km2 on the southern margin of the Palaeoproterozoic Northern... -
Ferricretes and deep weathering profiles of the Puzzler Walls, Charters...
The Charters Towers district in semi-arid tropical north Queensland has large areas of transported and residual cover. It is host to several major gold and base-metal deposits... -
Macroseismic effects, locations and magnitudes of some early Tasmanian earthquakes
The Richter magnitude, ML, for historical earthquakes can be obtained from the Modified Mercalli intensity, I, and hypocentral distance, R (km) using the formula ML = 1.13 In R... -
The signature of terrestrial impacts
The high level of endogenic geological activity makes the terrestrial record of impact difficult to read. Terrestrial processes, such as erosion, rapidly modify craterforms and... -
Pattern of slow seafloor spreading (<4 mm/year) from breakup (96 Ma) to A20...
Australia separated from Antarctica by continental extension between the mid-Jurassic (>160 Ma) and mid-Cretaceous (96 Ma), then by slow seafloor spreading (half-rate <... -
Stable isotope and chemical studies of volcanic exhalations and thermal...
Thermal waters in Matupi Harbour and Sulphur Creek, Rabaul caldera have D/H and O18/O16 ratios that are indicative of a mixed source. They are the result of mixing of local... -
The early geological history of the Proterozoic Mount Isa Inlier,...
Correlations within the Proterozoic succession are complicated by repetitions of similar rock types at different stratigraphic levels, especially acid and basic volcanics,... -
Australian crater-forming meteorites
Meteorites are associated with five impact structures in Australia. Three of them are group IIIAB irons (Wolf Creek, Henbury, and Boxhole), Veevers is a group IIAB iron, and... -
Risk assessment as a framework for management of aquifers - a literature review
The initial step in a risk assessment is to identify the hazards and the assets they threaten. The next step is then to estimate the likelihood of releases of different... -
