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... -
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,... -
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... -
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... -
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... -
Seismic refraction - a tool for studying coral reef growth
Seismic refraction studies have been conducted in close proximity to shallow boreholes previously drilled at Bewick (Northern Great Barrier Reef), Hayman (Central Great Barrier... -
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... -
The sediments of the Argo Abyssal Plain and adjacent areas, northeast Indian Ocean
A series of geophysical traverses by the Atlantis II across the Argo Abyssal Plain, together with coring at a number of selected localities has provided new information on... -
Geological note: Igneous and sedimentary rocks dredged from the northern...
Altered basalt, dolerite and gabbro have been dredged from a previously unsampled portion of the Macquarie Ridge (47o-48° S), using the commercial fishing vessel Amaltal... -
Tectonic and sedimentary history of the Argo Abyssal Plain, eastern Indian Ocean
Bathymetric and seismic reflection profiles totalling about 2800 km, and covering about 110 000 km2 of the Argo Abyssal plain, have been analysed. The early emplacement of... -
Western Australia: Phanerozoic geology and mineral resources
Phanerozoic rocks in onshore Western Australia are primarily sedimentary. Volcanic and intrusive rocks are known from only a few areas and are mostly related to continental... -
Impact of runoff on nutrient patterns in northern Port Phillip Bay, Victoria
As part of the Port Phillip Bay Environmental Study, bay-wide nutrient (ammonium, nitrate, nitrite, phosphate, silicate) and chlorophyll a distributions were measured at monthly... -
Holocene Palaeo-Environmental changes, central to north Great Barrier Reef inner zone
Fringing reefs and storm ridges, from inner-shelf sites on the Great Barrier Reef between 14° and 20° S, are examined for Holocene sea-level and climatic changes. The sites... -
A non-marine Lower Cretaceous rift-related epiclastic volcanic unit in...
The Early Cretaceous non-marine volcaniclastic Eumeralla Formation accumulated in a rift basin on the southern margin of Australia during the break-up of eastern Gondwana.... -
Palynostratigraphy of the Bookpurnong Beds and related Late Miocene-Early...
Dinoflagellates offer a reliable method for distinguishing the Late Miocene-Early Pliocene Bookpurnong beds from lithologically similar marginal marine sediments, such as the... -
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... -
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,... -
Late quaternary regional controls on the development of the Great Barrier...
High-resolution seismic reflection data have been examined in an attempt to identify and explain some of the regional differences and controls on the development of the Great... -
Palynology of the Oligocene-Miocene sequence in the Oakvale-1 corehole,...
Palynological analysis of the marine Oligocene-Miocene Geera Clay and Renmark Group in the Oakvale-l corehole in the western Murray Basin has shown diverse and well-preserved... -
