Earthquake duration magnitudes in southeast Australia, accounting for site,...
A new expression with superior consistency in the calculation of magnitude from earthquake coda duration has been developed. The need to take into consideration the site, the... -
A risk assessment of sulfonylurea herbicides leaching to groundwater
Improvements in agricultural production help sustain the worlds burgeoning population. The question is whether agricultural technologies degrade primary soil and water... -

Tightly folded migmatitic rocks, intruded by 1860 Ma granite and younger felsic and mafic dykes, are exposed in a band 95km long and up to 10km wide along the western part of... -
The Proterozoic Kalkadoon and Ewen Batholiths, Mount Isa Inlier, Queensland:...
The Proterozoic I-type Kalkadoon and Ewen Batholiths and their comagmatic extrusive equivalents, the Leichhardt suite, form an association covering at least 5000 km2 in the... -
The Polda Basin - a seismic interpretation of a Proterozoic-Mesozoic rift in...
The Polda Basin is an elongate easterly trending trough underlying the continental shelf in water depths of 50-200 m on the eastern side of the Great Australian Bight. It... -
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... -
Fifth BMR Symposium [Abstracts]
The 5th BMR Symposium was held in Canberra on the 28th and 29th April 1976, and was opened by the Minister for National Resources, the Rt. Hon. J. D. Anthony. These annual... -
Zircon U-Pb ages and geochemistry of igneous and metamorphic rocks in the...
High-grade metamorphic and felsic igneous rocks from the northern Prince Charles Mountains, East Antarctica, have been characterised geochemically and dated from SHRIMP zircon... -
Quaternary vadose calcretes revisited
Vadose calcretisation commences with precipitation of micritic calcite from carbonate-rich meteoric water in the soil moisture zone. Through time, calcrete is subjected to... -
Goyder impact structure, Arnhem Land, Northern Territory
A circular structural uplift of 3 kIn diameter in sandstone and mudstone of the Abner Sandstone crops out within the McArthur Basin of central Arnhem Land. Northern Territory,... -
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... -

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...
