Application of entropy-ratio maps to surficial reef facies, Great Barrier Reef
Entropy-ratio maps enable mapping of surficial facies of coral reefs at any chosen resolution. A ternary classification uses detritus, framework encrustation, and pavement as... -
The Ivanhoe Block-its structure, hydrogeology and effect on groundwaters of...
The Ivanhoe Block is a faulted and uplifted concealed basement ridge complex underlying the mallee sand dunes adjacent to the New South Wales part of the Western Riverine Plain... -
Upper Triassic spongiomorph and coral association dredged off the...
Upper Triassic corals and spongiomorphs dredged during BMR Cruise 95 from the Rowley Terrace, offshore Canning Basin of northwestern Australia, indicate possible new occurrences... -
Paleocene-Eocene biostratigraphy and palaeoenvironment of East Antarctica:...
The Mac. Robertson Shelf and western Prydz Bay, on the continental shelf of East Antarctica, were the sites of seismic/coring programs in February- March 1995 and 1997, and of... -
Seabed mapping using multibeam swath-mapping systems: an essential...
Swath-mapping of the seabed started soon after the Second World War, with small towed sidescan sonars providing images and built-in multi beam sonars providing bathymetry... -
Gravity provinces and their nomenclature
Gravity features have been defined and named by the various authors who have interpreted the results of land and marine reconnaissance gravity surveys in Australia. In general,... -
The elusive Cook volcano and other submarine forearc volcanoes in the Solomon Islands
Submarine volcanoes reported from the forearc region of the New Georgia Group are anomalously close to the line of northeast wards subduction of the Woodlark Basin. Kavachi is a... -
Effects of a major earthquake near Bougainville, 20 July 1975
On 20 July 1975 a major earthquake (MS7.9) shook the northern islands of the Solomon Islands chain. Damage amounting to at least $300,000 (Australian) occurred in the southern... -
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 mineral deposits of The Granites-Tanami and Tennant Creek...
The Palaeoproterozoic Tennant Creek Inlier (TCI) and The Granites-Tanami Inlier (GTI) share similarities in their stratigraphy and tectonic evolution. Both are characterised by... -
The Cretaceous of the Eromanga and Surat Basins
Little deformed Cretaceous sedimentary rocks underlie 1 500 000 km^2 of eastern Australia. Depositional environments in them range from freshwater to shallow marine. The... -
The Late Triassic molluscs, conodonts, and brachiopods of the Kuta...
The Kuta Formation is mainly a limestone deposit which crops out on the flanks of the Kubor Anticline in the Central Highlands of Papua New Guinea. It has been variously... -
Gravimetry in Australia, 1819-1976
The earliest known gravity measurements in Australia were made by French expeditions in 1819 and 1824, using pendulums at Sydney. Later in the 19th century, further pendulum... -
The crustal structure of the Gulf of Papua and northwest Coral Sea
Interpretation of seismic refraction data from the southwestern coast of the Papuan Peninsula and the northwest Coral Sea gives consistent results using several inversion... -
Origins of sulphide in sediments
Sulphide in sedimentary ore deposits may be derived directly from the mantle or by reduction of sulphate. Sulphide in modem hydrothermal deposits is thought to have formed... -
Late Cretaceous-Palaeogene nannofossil biostratigraphy of Challenger No. 1...
Late Cretaceous-Palaeogene calcareous nannofossil assemblages from the mainly carbonate section in Challenger No. 1 well, above the 780m level, have some similarities with the... -
Evidence of an exhalative origin for deposits of the Cobar district, New South Wales
Evidence is presented to show that a strong mineralogical/chemical zoning exists in seven deposits of the Cobar-Nymagee area. Characteristically, the within-deposit zoning,... -
The Proterozoic and Palaeozoic rocks of The Granites-Tanami region, Western...
The Granites-Tanami region links the mainly Proterozoic areas of northwestern and central Australia. It is made up of two main tectonic units: The Granites-Tanami Block, which... -
Free-air anomaly and gravity maps of Australia - in colour, 1:25,000,000
On the following pages are a Free-air Anomaly Map of Australia and a Gravity Map of Australia (showing Bouguer anomalies on land and free-air anomalies at sea), both at a scale... -
Spectral representation of isostatic models
The development of cross-spectral techniques for investigating the relation between gravity and topography has led to the representation of isostatic processes in terms of...
