Logistics report for down-hole conductivity logging in the Pine Creek AEM Survey area, Northern Territory, 2008

Induction conductivity data, commonly referred to as conductivity logs, were acquired from twenty four boreholes during two field campaigns in April and October 2008 in support of the Pine Creek airborne electromagnetic (AEM) survey, described in Costelloe (2010). The Pine Creek AEM survey comprises three areas: Kombolgie to the east of Kakadu National Park; Woolner Granite near Darwin; and, Rum Jungle to the west of Kakadu National Park. Data in the Woolner Granite and Rum Jungle survey areas were acquired using the TEMPESTTM fixed wing AEM system.  The acquisition and processing were carried out by Fugro Airborne Surveys Pty. Ltd. (FAS), under contract to GA.   In the Kombolgie survey area, the data were acquired by Geotech Airborne Pty. Ltd. (Geotech) using the VTEM helicopter AEM system.   The geophysical investigations were designed to deliver reliable, pre-competitive AEM data and scientific analysis of the energy resource potential of the Pine Creek region of Northern Territory.  The Pine Creek AEM survey covers a total area of 73 700 km2 in the Pine Creek region of the Northern Territory.

Great Artesian Basin Surat / Clarence-Moreton basins Hydrogeological Boundary

The approximate location of the Helidon Ridge (proposed name) - a basement ridge likely to define the hydrogeological boundary between the Surat and Clarence-Moreton basins in the GAB. To be used in conjunction with dataset 'Groundwater divide in the Hutton Sandstone boundary' (Geoscience Australia, Catalogue #77024, 2013) to define the easternmost boundary of the GAB.
The approximate location of the Helidon ridge was interpreted from a GOCAD model layer of Base of Hutton Sandstone surface (Geoscience Australia dataset, Catalogue #76025, 2013). 
This data set provides an approximate location of Helidon ridge as a polygon in Shapefile format. The polygon represents the area in which the boundary is likely to be located, as the exact location is open to interpretation. 
Data is available in Shapefile format

Post-seismic surveys in the epicentral area of the 1988 Tennant Creek, N.T. earthquakes

On 22 January 1988 three earthquakes of Ms 6.3-6.7 struck 30 km southwest of Tennant Creek, N.T., Australia and produced approximately 32 km of surface faulting along two main scarps.  An extensive survey program in the epicentral area was conducted in February and March, 1988 by the Australian Surveying and Land Information Group (AUSLIG) on behalf of the Bureau of Mineral Resources in order to quantify the deformation associated with the earthquakes. The survey program consisted of: (1) aerial photography of the fault scarps; (2) 170 km of double run levelling; (3) three detailed levelling profiles of 3 km length; (4) 85 geodimeter traverses across the scarps at intervals of 0.5 km along the scarp; (5) global positioning system (GPS) measurements of the coordinates of temporary  benchmarks along the scarp and of portable seismograph stations; and (6) detailed surveying in selected areas. 
This report describes the survey program and tabulates the data that were collected.

GSSA Marree Thorium Grid Geodetic

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 radiometric thorium grid has a cell size of 0.00083 degrees (approximately 87m) and shows thorium element concentration of the Marree-Warrina Airborne Magnetic &amp; Radiometric Survey, SA, 2012 in units of parts per million (or ppm). The data used to produce this grid was acquired in 2012 by the SA Government, and consisted of 132484 line-kilometres of data at 400m line spacing and 80m terrain clearance.

Discrimination of surficial and bedrock magnetic sources in the Cobar area, NSW

Known mineral deposits in the Cobar area of NSW are magnetic. Hence, the magnetic method is an important tool in the search for mineral deposits in this area. Unfortunately, widespread occurrences of near-surface magnetic mineral accumulations commonly produce aeromagnetic anomalies similar to those expected from bedrock sources. Work by BMR during 1978 and 1979 has shown that the near-surface response is caused by laterite, which contains concentrations of hematite/maghemite minerals with high magnetic remanence and/or susceptibility. These magnetic minerals usually occur in surface layers up to 10 m thick and exhibit large lateral and vertical variations in magnetic properties over small distances. Frequency domain analysis of both model and field magnetic data shows the spectral signatures of bedrock and near-surface sources to be distinctly different. Hence, spectral techniques may be used to separate the responses of bedrock and near-surface sources which occur at the same locality, if high resolution data are available. A comparison of the response of near-surface and bedrock sources by modelling indicates that, with careful survey design, a magnetic target such as Elura could be detected at a depth of 300 m, even in areas of severe surface magnetic noise.

MRTAS Norfolk Range tmi grid geodetic

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.
This MRTAS Norfolk Range tmi grid geodetic has a cell size of 0.00021 degrees (approximately 20m). The units are in nanoTesla (or nT). The data used to produce this grid was acquired in 1996 by the TAS Government, and consisted of 17093 line-kilometres of data at a line spacing between 100m and 200m, and 90m terrain clearance.

AUSGeoid98 v.1.0 data files: Petermann Ranges (sg52-07)

AUSGeoid98 data files contain a 2 minute grid of AUSGeoid98 data covering the Australian region, which you can use to interpolate geoid-ellipsoid separations for the positions required.You can use your own interpolation software, or you can use Geoscience Australia's Windows Interpolation software (Winter). The data files are text files in a standard format that cover the same area as standard topographic map areas. Files covering both 1:250,000 (approximately 100 x 150 km) and 1:1,000,000 (approximately 400 x 600 km) map areas are available. There is a 4 minute overlap on all sides of each area. Data format: AUSGeoid98 data files have a header record at the start of each file, to distinguish them from the superseded AUSGeoid93 data files. AUSGeoid98 data files show the geoid-ellipsoid separation to 3 decimal places, while the superseded AUSGeoid93 data files showed only 2 decimal places. AUSGeoid98 deflections of the vertical were computed from the geoid-ellipsoid separation surface, while the AUSGeoid93 deflections of the vertical were computed from OSU91A.

Distribution, timing and origin of magmatism in the Bight and Eucla basins, with implications for hydrocarbon prospectivity

The breakup of Gondwana during the Mesozoic resulted in widespread basin formation along Australia's southern margin, of which the Bight Basin is a component. In contrast to many other extensional margins, the Australian southern margin has been classified as a non-volcanic rifted margin, despite the reported occurrence of scattered volcanic and intrusive rocks in the geological literature. Public release of the Flinders 2D seismic survey data in the Bight Basin has allowed the accurate mapping of widespread sills, dykes, lava flows and volcanoes.
