A re-assessment of stromatolite evidence for the correlation of the late...
The identification of a stromatolite sample as Baicalia cf. B. burra has been used as evidence for the correlation of the Late Proterozoic Neale beds and Ilma beds in the... -
Geophysical response of heavy-mineral sand deposits at Jerusalem Creek, New...
BMR has started evaluating how geophysical methods might assist in exploration for deposits of the heavy minerals rutile, zircon, ilmenite, and monazite. Historically,... -
Environmental consequences of saline groundwater intrusion into the Wimmera...
Saline groundwater intrusions into lowland reaches of the Wimmera River, western Victoria, accumulated under low-flow conditions and formed stable saline pools. An extensive... -
Crustal reactions resulting from the mid-Pliocene to Recent continent-island...
The Sunda and Banda Arcs are contiguous surface features associated with the convergent boundary between the Southeast Asian and Australian-Indian Ocean plates, and where these... -
Earthquake Risk in Australia
Earthquake risk maps of Australia were prepared using a computer program which selected events from a regional earthquake file and calculated maximum values of acceleration,... -
Variation of crustal mass over the Australian region
Seismic refraction surveys in Australia and nearby marine areas provide data on crustal velocities and layer thicknesses. The averages of these at various places have been used... -
Coronation Hill U-Au mine, South Alligator Valley, Northern Territory: an...
Host rocks to the Coronation Hill U-Au mine have long been regarded as agglomerate occupying a volcanic vent, and, as such, the deposit has been regarded as volcanogenic and... -
Geobiological role of cyanobacterial mats in sedimentary environments:...
Cyanobacterial mats are among the most productive of aquatic photosynthetic systems. They were prevalent during the Precambrian, but now occupy limited, albeit widespread,... -

The Australian regolith and mineral exploration
Much of the Australian landscape is old. In places, such as the western shields, its origin can be traced to the Precambrian, but elsewhere it dates from the Palaeozoic to... -
Revised stratigraphy of the Ordovician (Late Tremadoc-Arenig) Prices Creek...
The Early Ordovician (late Tremadoc to Arenig) Prices Creek Group outcrops only on the northern margin of the Canning Basin in a small area centred on Prices Creek, 60 km... -
Late Triassic conodont and palynomorph biostratigraphy and conodont thermal...
Late Triassic (Norian-Rhaetian) conodonts recovered from borecores and sea-bottom dredge samples on the North West Shelf off Western Australia are assigned to the... -
Methane anomalies in seawaters of the Ragay Gulf, Philippines: methane...
The vertical distribution of methane has been measured in the water column of a semi-enclosed basin, the Ragay Gulf, in the Philippines archipelago. The methane distribution is... -
Groundwater nitrate in East Java, Indonesia
Surveys were carried out in East Java, Indonesia, to determine the nitrate concentrations of (a) household well waters in selected settlements, (b) certain other waters, and (c)... -
The Proterozoic impact record of Australia
Six impact structures of known or probable Proterozoic age have been identified in Australia: (1) the Teague Ring structure in central Western Australia, 30 km in diameter and... -
Geochemistry of the Cullen Granite, Northern Territory
A geochemical study of the Cullen Granite in the Northern Territory, involving major elements and 25 trace elements (Li, Be, F, S, V, Co, Ni, Cu, Zn, Ga, As, Rb, Sr, Y, Zr, Nb,... -
The ancient Murray River system
It has previously been suggested that an ancient Murray River once extended across the present line of the Mt Lofty Ranges, and emptied into Spencer Gulf. Evidence available... -
Regional magnetic and gravity responses of extensional sedimentary basins
The gravity and magnetic responses of extensional sedimentary basins vary wi th the stages of basin development. The major observed gravity responses are regional gravity highs,... -
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...
