Hydrochemistry of a groundwater-seawater mixing zone, Nauru Island, central...
Nauru Island is a karstified dolomitic limestone island in the central Pacific Ocean. A thin, discontinuous freshwater layer overlies a thick brackish water mixing zone. In the... -
The use of sediments to assess environmental impact on a large coastal...
Sediment samples (140) acquired from the estuarine and fluvial sections of the Hawkesbury River between Windsor (130 km from the coast) and Broken Bay have been analysed for... -
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,... -
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... -
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 evolution of One Tree Reef, Southern Great Barrier Reef, Queensland
One Tree Reef is one of fourteen reefs in the Capricorn Group, southern Great Barrier Reef. The reef has an asymmetrical triangular shape, 5.5 km long and 3 km wide, with a... -
Mesozoic Bivalvia from Clerke and Mermaid Canyons, northwest Australian...
Four sets of rock samples from two sites off the northwest Australian shelf in 3625-4480 m of water contain macrofaunas, mainly bivalves, of warm shallow-water origin. Mermaid... -
Regional plate tectonics and the evolution of Australia's passive continental margins
The divergent, passive continental margins around Australia have evolved through the progressive dissection of eastern Gondwanaland in five separate seafloor-spreading episodes.... -
Structure and tectonic history of the northern Exmouth Plateau and Rowley...
A series of regional seismic reflection lines has been recorded, which link three key exploration wells on the northern Exmouth Plateau and Rowley Terrace to the lower... -
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... -
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... -
Oldest Cretaceous sequence, Giralia Anticline, Carnarvon Basin, Western...
Outcrop of the oldest Cretaceous sequence in the Giralia Anticline and the Giralia No. 1 well, penetrating the same sequence, are described and biostratigraphically assessed in... -
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... -
Origins of groundwater salinity near Tresco, northwest Victoria
Core samples and groundwater from bores at Tresco, northern Victoria, in the southern margin of the Murray Basin, have been analysed for palynology and chemistry. An aquifer... -
Reef growth, southern Great Barrier Reef - preliminary results
The reefs of the Capricorn-Bunker Group in the southern Great Barrier Reef were the focus of a Bureau of Mineral Resources survey in September-October 1976. Subaerial and... -
Quaternary and modern environments of the Van Diemen Rise, Timor Sea, and...
Environmental baseline data are required for Australias offshore areas before petroleum exploration. This has boosted demand for analysis and interpretation of the Quaternary... -
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... -
