Hydrogeology of a raised coral atoll - Niue Island, South Pacific Ocean
Niue Island, in the south Pacific Ocean, is a raised coral atoll with an area of 259 km^2. The original atoll rim is preserved as a peripheral ridge about 60 m above sea level,... -
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... -
Geological history of the outer North West Shelf of Australia: a synthesis
This paper uses information contained in other papers in this issue of the AGSO Journal together with the scientific literature to produce a synthesis of the geological... -
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... -
The nature and origin of beach ridges, western Cape York Peninsula, Queensland
Two sets of beach ridges are known from the western side of Cape York Peninsula. The older set are thought to be late Pleistocene. They rest on a basement of older fan deposits... -
Archaeocyatha of the Amadeus and Georgina Basins
The Todd River Dolomite (Amadeus Basin) and Mount Baldwin Formation (Georgina Basin) are a part of the Early Cambrian platform cover of the central Australian craton. Marine... -

Thelodont scales recovered from the basal (calcareous) unit of the Cravens Peak Beds in the Georgina Basin, are referable to Turinia australiensis Gross, 1971, T. cf. pagei... -
Significance of calcareous nannofossil-bearing Jurassic and Cretaceous...
Examination of dredge hauls taken from the Rowley Terrace, northwest Australia, has revealed the occurrence of several Mesozoic nannofossil-bearing levels. Dating has been... -
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... -
Stratigraphy and sedimentology of mid-Tertiary permeability barriers in the...
In the Murray Basin of southeastern Australia, the accelerated emergence of groundwater-related salinity problems in recent decades has led to the realisation that future... -

During the geological mapping of the Mount Anderson Sheet area of the Canning Basin in 1976, an exposure of the Jurassic Jurgurra Sandstone about 20 km north of the type... -
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... -

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... -
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... -
