Mt Barker, WA, 2011 (P1245), 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 South West (Mt Barker and Lake Muir), WA, 2011 survey were acquired in 2012 by the WA Government, and consisted of 126090 line-kilometres of data at a line spacing between 200m and 300m, and 50m terrain clearance.

Eyre Peninsula (Streaky Bay, Yardea, Elliston, Kimba), SA, 1988 (P549), 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 Eyre Peninsula (Streaky Bay, Yardea, Elliston, Kimba), SA, 1988 survey were acquired in 1988 by the SA Government, and consisted of 28747 line-kilometres of data at 1000m line spacing and 105m 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.

1996 Vulcan Sub-basin / Browse Basin Transition Airborne Laser Fluorosensor Survey Interpretation Report : (WGC Haydn survey number 2051)

The Haydn airborne laser fluorosensor (ALF) survey is located in the Vulcan Sub-basin, Timor Sea. The survey was flown in two sorties on the 2nd December 1996. Sixty-five lines were acquired at 400 m spacing in a NW-SE orientation with a total of about 550 square kilometres acquired. Seventeen lines were acquired at 1200 m spacing in the orthogonal NE-SW direction. The NW-SE lines were about 21.35 km long while the NE-SW lines were about 26 km long. Many types of noise were found on the ALF records and these were rejected during the manual checking phase of fluor selection.Of the 1,529,484 spectra recorded, only 21 were interpreted as having confident fluors. No significant fluorescence clusters were observed. Only 4 fluors were found with a F/R ratio above 0.30.

Synthetic magnetotelluric modelling of a regional fault network – implications for survey design and interpretation

The magnetotelluric (MT) method is increasingly being applied to mineral exploration under cover with several case studies showing that mineral systems can be imaged from the lower crust to the near surface. Driven by this success, the Australian Lithospheric Architecture Magnetotelluric Project (AusLAMP) is delivering long-period data on a 0.5° grid across Australia, and derived continental scale resistivity models that are helping to drive investment in mineral exploration in frontier areas. Part of this investment includes higher-resolution broadband MT surveys to enhance resolution of features of interest and improve targeting. To help gain best value for this investment it is important to have an understanding of the ability and limitations of MT to resolve features on different scales. Here we present synthetic modelling of conductive, narrow, near-vertical faults 500 m to 1500 m wide, and show that a station spacing of around 14 km across strike is sufficient to resolve these into the upper crust. However, the vertical extent of these features is not well constrained, with near-vertical planar features commonly resolved as two separate features. This highlights the need for careful interpretation of anomalies in MT inversion. In particular, in an exploration scenario, it is important to consider that a lack of interconnectivity between a lower crustal/upper mantle conductor and conductors higher up in the crust and the surface might be apparent only, and may not reflect reduced mineral prospectivity.

Northwest Northern Territory Seismic Survey, resource studies and results

Output Type: Exploring for the Future Extended Abstract

Short Abstract: As part of the Exploring for the Future (EFTF) program, Geoscience Australia acquired new 2D seismic reflection data across the northwestern Northern Territory (NT). Identified as an area of little knowledge during the Birrindudu Basin Inventory activity the Northwest Northern Territory Seismic Survey was acquired between August and September 2023 by Geoscience Australia and co-funded by the Northern Territory Government. The survey crosses the Proterozoic rocks of the Birrindudu Basin that are thought to be age equivalent to those within the McArthur Basin and Mount Isa Province to the east, which contain some of the world’s largest sediment-hosted base metals deposits, including McArthur River and Century and Mt Isa Pb-Zn-Cu mines. Further, additional complimentary studies provide evidence for an effective petroleum system in the Birrindudu Basin, demonstrated by the occurrence of live oil bleeds in the drill hole 99VRNTGSDD1 and good source rocks were identified mostly in the Paleoproterozoic Limbunya Group. However, many data gaps exist and much of the prospectivity for hydrocarbons in the Birrindudu Basin is inferred from the presence of equivalent-aged rocks in the highly prospective Paleo- to Mesoproterozoic McArthur Basin. To address data gaps, this new regional 2D seismic data was acquired and combined with a comprehensive sampling and analytical program on newly collected drill core samples, to assess the basin’s resource potential. The Northwest Northern Territory Seismic Survey has increased the seismic coverage of the Birrindudu Basin by ~900 km, and links to surveys in both the Beetaloo Sub-basin and Tanami. Interpretation of these deep seismic lines in combination with newly acquired data from drill cores and legacy 2D seismic lines will substantially improve the knowledge of mineral and energy systems in the northwestern Northern Territory.

Christmas Island Vegetation and Clearing Dataset

The Christmas Island Vegetation and Clearing Map was developed through a collaborative project by Geoscience Australia, Christmas Island Phosphates, and Christmas Island National Park during the 2013/2014 financial year. The map classifies the full extent of Christmas Island into vegetation and land cover classes. The dataset contains four attribute fields;
- Level 1 classification
- Level 2 classification
- Mean tree height (Mean_TreeH)
- Area (square m)
The majority of data was gathered in 2011, with an exception being the rehabilitation boundaries which are up to date as of May 2014.
The data represent the best position achievable with the limited resources available during the project's timespan. Geoscience Australia recognises that some data inputs could be improved with additional field checking. The boundaries of cleared areas have been verified in some cases only and may extend into primary, uncleared vegetation in places; ground-truth verification is strongly advised. Consequently, this information should not be relied upon as the sole information source when making operational decisions.

AUSGeoid98 v.1.0 data files: Kellerberrin (sh50-15 )

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.
