GSNSW Exploration NSW Area R Enngonia magnetic 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 GSNSW Exploration NSW Area R Enngonia magnetic grid geodetic has a cell size of 0.00077 degrees (approximately 80m). The units are in nanoTesla (or nT). The data used to produce this grid was acquired in 2001 by the NSW Government, and consisted of 34611 line-kilometres of data at 400m line spacing and 80m terrain clearance.

Tasmanian East Coast (GA4883)

This resource includes bathymetry data acquired during the Tasmanian East Coast bathymetry survey collected by Institute for Marine and Antarctic Studies (IMAS) University of Tasmania (UTAS) during the period 12 – 23 April 2021 on the RV Abyss using a Kongsberg Maritime EM2040C multibeam sonar (contracted from CSIRO). The Tasmanian East Coast bathymetry survey was led by Dr. Vanessa Lucieer (IMAS). The purpose of the project was to map the fine-scale spatial distribution of key abalone habitat impacted by urchins in &lt; 25 m water depth using multibeam acoustic imagery. This dataset contains seven 0.5m-resolution 32-bit floating point geotiff files of the bathymetry in study area and transits, derived from the processed EM2040C bathymetry data, using CARIS HIPS and SIPS software. A detailed report on the survey is provided in: Lucieer V, Keane J, Shelamoff V, Nau A, Ling S, Mapping abalone habitat impacted by Centrostephanus on the east coast of Tasmania: Final contracted report for the Abalone Industry Reinvestment Fund (AIRF Project 2021) and Tasmanian Climate Change Office (Climate Research Grants Program 2021), Institute for Marine and Antarctic Studies, UTAS, December (2021) [Contract Report] http://ecite.utas.edu.au/148298.

Remote sensing of mafic-ultramafic rocks: examples from Australian Precambrian terranes

Mafic and ultramafic rocks of the intrusive Andover Complex and Munni Munni Complex of the West Pilbara, and the Panton Intrusion of the East Kimberley, Western Australia, have been discriminated by Landsat-5 TM imagery.  Band-ratioing procedures were used to enhance spectral differences determined from field spectral-reflectance information.  For the Andover and Munni Munni Complexes, lithological discrimination is mainly based on the spectral response of different weathering products of the various ultramafic rock types.  For the Panton Intrusion, the discrimination represents variations in the weathering products of the plagioclase-rich gabbroic units.  Discrimination was hampered by vegetation-spinifex and lichen-and by fireburns.

AUSGeoid98 v.1.0 data files:  (si52-07)

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.

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.

Regional geology and mineral systems of the Stavely region, western Victoria. Data release 6 - Pre-drilling geophysics

The Stavely Project is a collaboration between Geoscience Australia and the Geological Survey of Victoria. During 2014, fourteen pre-competitive stratigraphic drill holes were completed in the prospective Stavely region in western Victoria in order to better understand subsurface geology and its potential for a variety of mineral systems. Prior to drilling, existing airborne magnetic data were analysed and new refraction seismic, reflection seismic and gravity data were acquired as part of a pre-drilling geophysical acquisition program. The aim of this geophysical program was to provide cover thickness estimates at the drill site locations prior to the drilling program commencing, in order to reduce the geological and financial risk. Passive seismic data were acquired post-drilling for benchmarking with the other methods against the completed drilling in order to assess a potential tool kit of geophysical methods for the explorer to predict reliably the cover thickness at the tenement scale.

The influence of geology on the location, design and construction of water supply dams in the Canberra area

The design and construction of safe and economic dams depends upon many factors, not least of which is an accurate assessment of the geology of the dam site and reservoir area. During the past 80 years, geological factors have caused the failure of, or serious damage to, at least 150 large dams throughout the world. Since 1945, ten possible sites for large water supply dams in the Canberra area have been geologically investigated; of these, three sites were selected for the design and construction of dams. In each case, the site selected, the type of dam constructed, and the layout of the engineering structures were decided upon only after detailed geological investigations. Geological mapping was carried out continuously during the construction of all three dams, and variations from the expected conditions were encountered at each site. Examples are given of problems caused by geological factors which arose at each site, together with the measures adopted to overcome the difficulties. Despite these problems, each of the dams was constructed at a cost very close to the original contract price, and no significant stability problems have occurred during their operation. The thorough geological investigations carried out at these sites have contributed significantly to the economic and safe construction of the three dams.
