Earthquake accelerograms and attenuation of seismic waves at Oolong, New South Wales

The first Australian earthquake accelerograms were obtained from an accelerograph situated in the Dalton-Gunning region of New South Wales. Preliminary results were obtained for earthquakes on 23 November 1976 (maximum resultant acceleration 0.66 m/s^2), 30 June 1977 (0.21 m/s^2), 4 July 1977 (0.95 m/s^2) and 3 February 1979 (1.3 m/s^2). Maximum ground velocities were calculated for these earthquakes, and isoseismal maps drawn for the earthquakes at Bowning on 30 June 1977 and 4 July 1977. These data were used to test the validity of the relation Y = ae^bM R^-C for assessing ground motion, and hence determining seismic risk. Because of the uncertainties in the derivation of analytical expressions for ground motions, the fit to observed values of acceleration, velocity and intensity is considered to be good. The relation recommended for use by the Seismic Sub-Committee of the Australian National Committee on Earthquake Engineering included a depth-adjusting factor Co, where (R^2 = D^2 + h^2 + Co^2). When Co was omitted a better fit to the observed accelerations was obtained, but a poorer fit to observed velocities. The isoseismal pattern for the 4 July 1977 earthquake supports the radiation pattern expected from the faulting suggested by the focal mechanism and distribution of aftershocks. The isoseismals for the 30 June 1977 earthquake show a different radiation pattern; this suggests a different focal mechanism.

High-resolution geophysics in modern geological mapping

A modern geoscientific knowledge base developed through systematic mapping is a major component of sustainable development strategies, underpinning mineral resource assessment and exploration.  High-resolution airborne magnetic and gamma-ray spectrometric surveys are fundamental to modern geoscientific mapping, providing cost-effective definition of structure and lithology in a diverse range of geological provinces and terrains.  Magnetic (and gravity) data are particularly valuable in determining basement structure and continuity under cover.  Gamma-ray spectrometric data provide geochemical (K, Th, U) maps that have proved valuable in mapping bedrock lithology and alteration, and for mapping regolith materials and activity, particularly in highly weathered (regolith-dominated) terrains.  More than 3 million line kilometres of new high-resolution airborne geophysics have been acquired by the Australian Commonwealth, State and Northern Territory geological surveys, since the commencement of the National Geoscience Mapping Accord, in support of geological mapping in a wide range of provinces.  These new data, coupled with other modern mapping technologies, notably geographic information systems, provide a means of rapid, cost-effective geoscientific mapping and analysis in a wide diversity of geological environments and terrains.  New geological maps and other thematic maps based on these geophysical data enable better definition of mineral potential and contribute directly to more effective and efficient exploration.  In all provinces, new high-resolution airborne magnetic and gamma-ray spectrometric data have resulted in better definition of both geological structure and lithological boundaries than indicated on previous maps. This paper shows, by examples, the usefulness of geophysical data over a wide range of mapping in support of the mineral industry.

Hydrogeology of the Yuendumu - Papunya - Kintore Region NT Western Water Study (Wiluraratja Kapi)

The hydrogeology of a 68 000 km2 region of arid central Australia has been assessed and mapped at 1:500 000 scale using a GIS to interpret various spatial data sets and compile statistics of water bore information. This work forms a part of the Western Water Study, a collaborative venture between Federal, Territory and Aboriginal representative agencies, which has the objective of improving access to groundwater information for Aboriginal people on their land. 
The study area is underlain by Proterozoic basement (Arunta Block), pre-Mesozoic sedimentary basins (Amadeus and Ngalia Basins) and Cainozoic sediments. Based on the analyses of 850 water bores , the study area is mapped as seven different aquifer systems to cover regional variations in hydrogeology. Palaeodrainages act as a sink along which groundwater drains to associated internal discharge playas. Statistical groundwater data for these systems and the individual geological formations drilled provide a starting point for further groundwater assessment in other areas of central Australia that have similar geology. Only one aquifer system representing about 3% of the study area in Cainozoic sediments along a mountain range consistently provides low salinity Â« 1000 mg/L) potable groundwater, though potable water can occasionally be found elsewhere throughout the region. Large individual bore yields of over 20Us can be found in the pre- Mesozoic and Cainozoic systems while a lack of storage precludes sustained high yield production from bores in the Proterozoic.

Serendipaceratops 3D cut-out model

Serendipaceratops (sair-en-dip-a-sair-a-tops). The full name of this dinosaur is Serendipaceratops arthurcclarkei. It is named for Arthur C. Clarke, author of books such as '2001 - A Space Odyssey' and 'Rendezvous with Rama'. Did you know that Clarke first became interested in science as a child because he was interested in dinosaurs?
Ceratopsian (sair-a-top-see-an) dinosaurs first appeared in the Early Cretaceous, the period of time immediately after the Jurassic. Ceratopsian dinosaurs had horns and beak-like jaws. A very well-known example was Triceratops, a North American dinosaur with three horns on its head and a large, bony neck frill. 
Serendipaceratops was one of the earliest known ceratopsian dinosaurs. It was actually a protoceratopsian - proto means first or original. The first known bone from Serendipaceratops was discovered in Australia near Kilcunda, on Victoria's south-east coast. It is a forearm bone (ulna) about 115 million years old. This fossil could be an important clue that ceratopsian dinosaurs evolved in, or near, Australia and not Asia as previously thought. Another ceratopsian arm bone was also found at Dinosaur Cove, in south-west Victoria. It is a little younger at 106 million years old.
As an early ceratopsian dinosaur, Serendipaceratops probably had beak-like jaws, only a very small neck frill and no horns. The beak-like jaw suggests it was a herbivore; a plant eater. This dinosaur was only about 2 metres long.

Macquarie Harbour, TAS, 1985 (P629), magnetic line data, AWAGS levelled

Total magnetic intensity (TMI) data measures variations in the intensity of the Earth's magnetic field caused by the contrasting content of rock-forming minerals in the Earth crust. Magnetic anomalies can be either positive (field stronger than normal) or negative (field weaker) depending on the susceptibility of the rock. The data are processed via standard methods to ensure the response recorded is that due only to the rocks in the ground. The results produce datasets that can be interpreted to reveal the geological structure of the sub-surface. The processed data is checked for quality by GA geophysicists to ensure that the final data released by GA are fit-for-purpose.
 These line dataset from the Macquarie Harbour &amp; Southwest Tasmania, TAS, 1985 survey were acquired in 1985 by the TAS Government, and consisted of 4833 line-kilometres of data at 500m line spacing and 188m terrain clearance. To constrain long wavelengths in the data, an independent data set, the Australia-wide Airborne Geophysical Survey (AWAGS) airborne magnetic data, was used to control the base levels of the survey data. This survey data is essentially levelled to AWAGS.

Visit to India, January, 1951

The Government of India invited the Australian Government to send a representative to the celebration of the Centenary of the Geological Survey of India during January 1951. The first meeting of the Pan-Indian Ocean Science Congress was scheduled for the first week in January, 1951 so the Bureau of Mineral Resources, Geology and Geophysics selected M.A. Condon to attend the Science Congress and the Centenary Celebrations because his work in the North-West Basin of Western Australia would be of some interest to geologists working around the Indian Ocean. This report comprises a detailed itinerary and geological notes on the areas visited during the course of the visit.
