Murrumbateman, NSW, 2010 Detailed Airborne Survey (P1253), elevation line data

The Digital Elevation Model represents ground surface topography between points of known elevation. The elevation data was calculated using the altimeters and Global Positioning System (GPS) sensor used for the benefit of airborne magnetic and radiometric data on the same survey. The elevation is the height relative to the Australian Height Datum GDA94 (AUSGEOID09). The processed elevation 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 Murrumbateman, NSW, 2010 Detailed Airborne Survey survey were acquired in 2010 by the NSW Government, and consisted of 1339 line-kilometres of data at 125m line spacing and 60m terrain clearance.

Palaeo- and Mesoproterozoic mineral deposits in Queensland

Proterozoic rocks crop out in northwest and far north Queensland. The Mount Isa Inlier, in the northwest, is a major producer of silver, lead, zinc and copper, and a small producer of gold. Recent exploration has led to several world-class base-metal discoveries and an upgrading of the provinces prospectivity. The other Proterozoic provinces in the Georgetown Region and the Coen Region have had a long history of diverse mining (with gold dominant), but much of the mineralisation is of Palaeozoic age with the Proterozoic rocks acting as hosts for many deposits and mineralised intrusions. Recent studies have indicated some similarities between the Etheridge Province (Georgetown Region) and the Mount Isa Inlier in terms of age, rock type and deformation history; the Etheridge Province in the Georgetown  Region may have potential for deposits of base metals of both sediment-hosted and Cannington type. The Coen Region is poorly studied and underexplored.

Mangana-Alberton, NE Tas, 1989 (P559), 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 Mangana-Alberton, NE Tas, 1989 survey were acquired in 1989 by the TAS Government, and consisted of 2755 line-kilometres of data at 500m line spacing and 243m 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.

Preliminary report on a semidetailed gravity survey at the McKenzie Rive area, western Victoria

A semi—detailed gravity survey was carried out on an area south of Horsham covering 500 square miles on both sides of the Mackenzie River to obtain closer detail of Bouguer anomalies, established in Western Victoria between Hamilton and Warracknabeal during the 1958 reconnaissance gravity survey.
The results of the survey confirm the existence of a major anomaly trend between Zumstein and Norton Creek. South of the Wimmera River a steepening in the gravity gradients occurs, which in the McKenzie Creek Quarry area is evidently related to outcrops of Palaeozoic Grampian Sandstone.
The assumption of a vertical displacement of the Palaeozoic sarldstones along a fault with 2,400 feet throw in conjunction with a density contrast of 0,4 between the Grampian Sandstone and younger sediments east of this fault would sufficiently explain this gravity anomaly.

AUSPOS: Geoscience Australia's on line GPS positioning service

AUSPOS is Geoscience Australia's on-line static GPS positioning service, providing user access to a state-of-art analysis system via a simple web-interface. Since its launch in 2001, AUSPOS has continued to be a widely used tool for the online processing of geodetic GPS data for surveying, mapping, geodetic, geophysical, hydrographical, mining, construction, military and other applications. On 20 March 2011, Geoscience Australia released an updated version of the service. The updated AUSPOS implements recent advances in analysis software and strategies, the reference frame ITRF2008, AusGeoid09 and the latest transformation parameters between ITRF2008 and GDA94. AUSPOS now delivers precise ITRF2008 coordinates to users within 3-5 minutes while continuing to provide Australian users with access to GDA94 coordinates and derived AHD heights to the highest achievable accuracy by simultaneously processing up to 7 days of user-supplied GPS data from up to 20 sites. The updated AUSPOS also provides more realistic coordinate uncertainty of its solutions using a recently developed assessment method of coordinate uncertainty, which is based on the duration of data sets and their global location. In this presentation, the current status of AUSPOS will be overviewed as well as plans for its ongoing improvement.

Geochemistry and tectonic significance of Proterozoic mafic rocks from the Georgetown Inlier, north Queensland

Mafic igneous rocks were emplaced during deposition of the Robertson River Subgroup, part of the early or Middle Proterozoic Etheridge Group in the Georgetown Inlier. They comprise the Dead Horse Metabasalt and the Cobbold Metadolerite, which forms a multitude of sills both above and below the Dead Horse Metabasalt. They are metamorphosed to lower greenschist to granulite facies, and are probably equivalant to amphibolite and mafic granulite in the Einasleigh Metamorphics. The rocks are geochemically similar to modern mid-ocean ridge basalts (MORB) . However, sedimentological evidence indicates that the Etheridge Group was deposited in shallow water on a shelf or in an epicontinental sea.  The mafic rocks may, therefore, be similar to the low-K flood basalts of Greenland and Baffin Island, although the low K could be partly due to depletion during metamorphism. Except for the much lower K, they are similar to the relatively incompatible-element depleted Karoo basalts and dolerites. They are also similar geochemically to some Proterozoic mafic rock suites from the Mount Isa and Pine Creek areas in northern Australia. The mafic rocks from the Etheridge Group may be the expression of convective mantle upwelling, which could have produced extension of the Proterozoic crust and the formation of a shallow epicontinental sea in which the Etheridge Group was deposited. No evidence of any associated rifting occurs in the Georgetown Inlier.
