Wessel Islands 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The R502 series of maps has been replaced by the National Topographic Map Series (NTMS).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.

Geology of the Prince Charles Mountains, Antarctica

The Prince Charles Mountains constitute by far the best-exposed cross section through the East Antarctic Shield, extending for over 500 kilometers along the drainage basin of the Lambert Glacier-Amery Ice Shelf system. They consist of three distinct geological terranes: 
the Archaean to 'Mesoproterozoic Ruker Terrane in the south and the Mesoproterozoic to early Neoproterozoic Fisher and Beaver-Lambert Terranes in the north.

Prince Regent totalcount grid

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. The terrestrial dose rate grid is derived as a linear combination of the filtered K, U and Th grids. A low pass filter is applied to this grid to generate the filtered terrestrial dose rate grid.
This Prince Regent totalcount grid has a cell size of 0.00167 degrees (approximately 182m) and shows the terrestrial dose rate of the Prince Regent, Camden Sound, Montague Sound, WA, 1994. The data used to produce this grid was acquired in 1994 by the WA Government, and consisted of 61497 line-kilometres of data at 800m line spacing and 100m terrain clearance.

Paterson Southeast, WA, 2005 (P1093), 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 Paterson Southeast, WA, 2005 survey were acquired in 2005 by the WA Government, and consisted of 28455 line-kilometres of data at 400m line spacing and 60m terrain clearance.

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.

Iron oxide-copper-gold potential of the southern Arunta Region

Iron oxide-copper-gold (IOCG) mineral systems occur globally and range in age from Archean to Mesozoic or younger. An assessment for IOCG mineral system potential has been undertaken in the southern Arunta Region, incorporating the southern Aileron and northern Warumpi provinces. The assessment has been undertaken in a GIS-based environment using a mineral systems approach. This approach recognises four key system components: (1) sources of metals and fluids, (2) fluid-flow drivers, (3) fluid-flow pathways and architecture, and (4) depositional sites and mechanisms. For each of these key system components, mappable criteria were developed as proxies for mineralising processes in order to identify potential IOCG mineral systems. The locations of known deposits and prospects were not used for generating the assessment of IOCG potential. However, they are used as a validation of the results. The assessment largely reproduces the locations of known IOCG-style mineralisation, and predicts additional potential in a number of other areas, many of which are obscured by recent sedimentary cover. An approximately east-west-trending belt of broad IOCG potential has been identified, along with local regions of high potential where favourable criteria occur.

Breena Plains 1996 Gravity Survey, Qld (P199648), gravity point data

Gravity data measures small changes in gravity due to changes in the density of rocks beneath the Earth's surface. 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 Breena Plains 1996 Gravity Survey, Qld (P199648) contains a total of 1552 point data values acquired at a spacing between 250 and 500 metres. The data is located in QLD and were acquired in 1996, under project No. 199648 for BHP Group Ltd.

Reconnaissance of upper crustal seismic velocities in the Tennant Creek Block, Northern Territory

Upper crustal seismic investigations of the Tennant Creek Block indicate that the Warramunga Group rocks have P-wave velocities of 5.22-5.55 km/s (average 5.42 km/s) and S-wave velocities of 3.26-3.41 km/s (average 3.34 km/s). The P-wave velocity beneath these surface rocks is 6.06 km/s. A simple layered model for the thickness of the Warramunga Group gives values of about 2.6 km near Nobles Nob mine, thinning to about 1.2 km near Warrego mine. South of the Warramunga Group rocks, granitic rocks have an estimated upper value for the P-wave velocity of 5.69 km/s. Underneath, the P-wave velocity of 6.06 km/s is the same as that further north, under the Warramunga Group rocks, but the depth to this velocity is as much as 0.7 km less. The corresponding S-wave velocity is 3.53-3.59 km/s. An intracrustal S-wave velocity of 3.86 km/s is observed from the Warrego shot. The nature of the change between the surface and basement rocks is likely to be complex, resulting in a velocity transition zone rather than a simple boundary. The estimated depths to basement are, therefore, minimum estimates. Because of the expected increase in the seismic velocity of the rocks when subjected to overburden pressures equivalent to depths of 2-3 km, there is little evidence from the present work that the basement is compositionally or lithologically different from the surface rocks. At recording distances beyond 50 km there is evidence in the record sections that both P and S-wave energy is being returned from deeper intracrustal refractors/reflectors.

Surat-Galilee Region AEM SkyTEM airborne electromagnetic survey

A SkyTEM airborne electromagnetic (AEM) survey was flown over Surat and Galilee regions of Queensland, Australia during July 2017. The Surat-Galilee area was surveyed, with multiple survey sites in Orana, Injune and Galilee. The area is comprised of 1293 line kilometres in Orana, 552 line kilometres in Injune and 2922 line kilometres in Galilee. A total of 4767 line kilometres were flown for this survey. The projected grid coordinates have been supplied in GDA94 MGA Zone 55 for Galilee and Injune and in MGA zone 56 for Orana.
The aim of the survey is to provide at a reconnaissance scale:
a)  trends in regolith thickness and variability
b)  variations in bedrock conductivity
c)  conductivity of key bedrock (lithology related) conductive units under cover
d)  the groundwater resource potential of the region
e)  palaeovalley systems known to exist in the region.
