A new passive margin model for the Neoproterozoic and Early Palaeozoic of SE Australia derived from seismic studies of Tasmania

The island of Tasmania in southeast Australia has a number of geological elements. The relationship between these elements is largely obscured by younger cover of the Tasmania Basin, including extensive dolerites which limit the ability of potential field techniques to map basement. Therefore the development of a robust tectonic model for Tasmania has been inhibited. A seismic program was undertaken to map the large scale structure of Tasmania at depth. Deep seismic profiles were collected offshore along the entire coastline; the airguns were also recorded at a number of seismographs deployed across the island, allowing low resolution 3D tomographic imaging. Short reflection profiles were also recorded onshore across structures which could not be imaged by the offshore profiling. The Proterozoic basement in the northwest and in the Tyennan Block in the core of the island is unreflective, except for mostly east dipping reflectors which project to the surface at block boundaries. In the east, however, the lower crust is broken into rotated blocks whose boundary faults are reflective, indicating progressively greater crustal extension of the Tyennan Block to the northeast, where a reflective lower crust is interpreted to be highly extended continental crust with passive margin sediments and possibly fragments of oceanic crust. The apparently complex geology of Tasmania therefore fits into a Simple tectonic model in which several episodes of crustal extension occurred before oceanic crust formed to the northeast. The extended crust has now been inverted, probably from the northeast.

Hughenden 1:250 000, R502 historical topographic map

The R502 series of maps has been replaced by the National Topographic Map Series (NTMS). The R502 series consists of 542 map sheets and covers Australia at a scale of 1:250,000. It was compiled from aerial photography, but only about one quarter of the series was contoured. The standard sheet size is 1 degree of latitude by 1.5 degrees of longitude. Transverse Mercator map projection and Clark 1858 datum were used. Coverage of the country was completed in 1968.

Western Desert AEM Survey Map

Using an airborne electro-magnetic system previously unused in Australia called Spectrem, the Geoscience Australia groundwater survey will measure variations in the electrical conductivity of the ground. The survey was planned in the remote south-west of the Northern Territory near the West Australian border around the communities of Kintore, Nyirripi and Papunya, in 2011 but was not flown due to circumstances beyond our control.

Sir Samuel, WA, 1993 (P596), radiometric line data, AWAGS levelled

The radiometric, or gamma-ray spectrometric method, measures the natural variations in the gamma-rays detected near the Earth's surface as the result of the natural radioactive decay of potassium (K), uranium (U) and thorium (Th). The data collected 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.
 This Sir Samuel, WA, 1993 (P596), radiometric line data, AWAGS levelled were acquired in 1993 by the WA Government, and consisted of 47075 line-kilometres of data at 400m line spacing and 100m 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.

New insights into some of Australia's giant deposits through seismic reflection surveys -  Exploration implications

This address was presented at the annual Prospectors and Developers Association of Canada International Convention, Trade Show and Investors Exchange (PDAC), 4-6 March 2005 in Toronto, Canada. 
Geoscience Australia's use of deep crustal seismic reflection imaging techniques to determine the crustal architecture near several world-class mineral deposits (Kalgoorlie, Broken Hill, Mount Isa, McArthur River, Olympic Dam) is challenging current understanding of Australia's geology, ore deposit models and prospectivity. The focus has been identifying the main crustal-scale fluid migration pathways and depositional environment (traps). Seismic reflection images suggest that the crust of the Eastern Goldfields (Yilgarn Craton) formed in an accretionary orogen with gold associated with higher-order splays along corridors linked to crustal-penetrating faults. 
The Broken Hill survey showed the major structures dip SE (not NW) leading to a new 3D geological model for the supergiant Ag-Pb-Zn Broken Hill deposit. The Mt Isa seismic survey suggests that mineralised fluid circulation in the Western Succession was controlled by the Adelheid Fault not the Mt Isa Fault, and revealed Cu-Au deposits associated with the previously unmapped Marimo Fault in the Eastern Succession. The super giant Olympic Dam deposit (3810 Mt @ 1.1% Cu, 0.4 kg/t U308, 0.5 g/t Au) is associated with mantle-penetrating structures at a major crustal boundary. The giant McArthur River Ag-Pb-Zn deposit lies at the edge of a foreland fold-and-thrust belt rather than a rift setting. The newly-defined crustal architecture for many of these deposits requires a re-examination of current geological and ore deposit models. We discuss the exploration implications of these new results and the use of seismic to image alteration haloes around ore bodies.

Bendigo VIC Hydrogeological map of the Murray Basin series 1:250 000

The objectives of hydrogeologically mapping the Murray basin were to generate a set of maps at 1:250 000 scale to: 

show the influence of groundwater on land salinisation and surface water salinity 
delineate useable groundwater resources 
highlight present and potential salinity hazard and 
enhance community awareness and understanding of groundwater systems and processes 

and provide a groundwater data-base for the Murray Basin to facilitate land and water resource management decisions. 
The production of the Murray Basin Hydrogeological Map Series was a major coordinated Government action in the management of groundwater to combat degradation through salinisation and enable sustainable land and water use in the Murray Basin.  The Hydrogeological Map Series was a collaborative effort between the various water authorities of South Australia, Victoria and New South Wales. 
Explaining this product in detail is an article by Evans, W.R. 1992, "The Murray Basin Hydrogeological Map Series", Water pp. 20-23.

BMRs legacy and AGSOs mission: strategic influences on the future direction of Australia's national geological survey

Rapid changes in the operating environment for national geological surveys are forcing an almost constant re-evaluation of their role and the Australian Geological Survey Organisation is no exception.  The diversification of the Australian Geological Survey Organisations client base to include national resource managers and policy makers, the changing demands of an increasingly competitive minerals and petroleum industry, and changes in government policy relating to program delivery have created the need for a sharp client focus on the organisations work and output.  This paper explores the present needs for geoscience information and draws some implications for the future direction of Australias national geological survey.
