The upper crustal geology of the Georgina Basin region
Pattern recognition in regional maps of Bouguer anomalies and total magnetic intensity contours suggests that the basement of the Georgina Basin can be divided into four... -
Quasicyclammina gen. nov. and Thalmannammina (Foraminiferida) from the...
The new genus Quasicyclammina is described from the Lagaip Beds of upper Paleocene age in the Wabag area, Papua New Guinea; it is placed in the subfamily Cyclammininae of the... -
Recovering degraded groundwater in the Angas-Bremer basin through community action
Recovering a groundwater basin degraded by salinity caused by an overdraft is difficult and involves significant conflict with the community. This paper discusses how a... -
Western extension of the Woodroffe Thrust, Musgrave Block, central Australia
The Woodroffe Thrust has until now been known in outcrop only in South Australia and the Northern Territory, where it forms part of a system of south-dipping thrust faults that... -
Earth's evolution and mineral resources, with particular emphasis on...
From 3.5 Ga the overall uniformity of the composition and character of sedimentary and mantle- and crustal-derived igneous rocks, and the persistence of ore types related to... -
Sedimentology of the Neoproterozoic Acraman impact-ejecta horizon, South Australia
The Acraman ejecta horizon is a thin (0-40 cm ) sand/breccia unit consisting almost entirely of angular volcanic fragments. The horizon occurs within Neoproterozoic (~590 Ma)... -
Sediment-water interaction in Australian coastal environments: implications...
Limited Australian data on sedimentary processes- C, N, P, Fe and Si diagenesis at the sediment/water interface- have been reviewed. These and the results of more recent work... -
Probabilistic earthquake risk maps of Tasmania
New earthquake risk maps of Tasmania have been prepared depicting risk by contours of peak ground velocity, acceleration and intensity with a 10 per cent probability of being... -
Towards distinguishing transported and in situ ferricretes: data from...
Controversy has arisen in the past decade concerning ferricrete genesis by relative (in situ) or absolute (lateral) concentration of iron and aluminium oxides. Some regard... -

The Bullara Limestone, a new rock-stratigraphic unit from the Carnarvon...
A new rock unit, the Bullara Limestone, is proposed for a Late Oligocene bioclastic limestone, which is probably restricted to the subsurface of Rough Range. The Bullara... -
Pollution of a fractured rock aquifer by petrol - a case study
Shallow groundwater aquifers are susceptible to pollution by various contaminants. Amongst them, refined petroleum products are a serious hazard, because of their immiscibility... -

DISCUSSION: Major geomorphic features of the Kosciusko-Bega region
Discussion: Ollier and Taylor (1988) are correct when they write that the Kosciusko- Bega region has long been of interest to geomorphologists, They also point out that there... -
Palynology of Tertiary Lake Bunyan, Cooma, New South Wales
Pollen and spore assemblages have been recovered from coaly lenses and marginal facies of Tertiary lacustrine sediments at Lake Bunyan, north of Cooma, southern New South Wales.... -
The Appin (New South Wales) earthquake of 15 November 1981
The earthquake that occurred near Appin, New South Wales, on 15 November 1981 and its aftershock of 19 November were both associated with thrust faulting in the middle crust... -
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,...
