AUSGeoid98 v.1.0 data files:  (sb50-13)

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 Data format: AUSGeoid98 data files have a header record at the start of each file, to distinguish them from the superseded AUSGeoid93 data files. AUSGeoid98 data files show the geoid-ellipsoid separation to 3 decimal places, while the superseded AUSGeoid93 data files showed only 2 decimal places.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.

GSV Pitfield Plains Vic 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 GSV Pitfield Plains Vic magnetic grid geodetic has a cell size of 0.0005 degrees (approximately 49m). The units are in nanoTesla (or nT). The data used to produce this grid was acquired in 1987 by the VIC Government, and consisted of 1295 line-kilometres of data at 250m line spacing and 80m terrain clearance.

Concept of a Satellite Cross-Calibration Radiometer for in-orbit Calibration of Commercial Optical Satellites

The satellite Earth observation (EO) sector is burgeoning with hundreds of commercial satellites being launched each year, delivering a rich source of data that could be exploited for societal benefit. Data streams from the growing number of commercial satellites are of variable quality, limiting the potential for their combined use in science applications that need long time-series data from multiple sources. The quality of calibration performed on optical sensors onboard many satellite systems is highly variable due to calibration methods, sensor design, mission objective, budget, or other operational constraints. A small number of currently operating well-characterised satellite systems with onboard calibration, such as Landsat-8/9 and Sentinel-2, and planned future missions, like the NASA Climate Absolute Radiance and Refractivity Observatory (CLARREO) Pathfinder, the European Space Agency (ESA)’s Traceable Radiometry Underpinning Terrestrial and Helio Studies (TRUTHS), and LIBRA from China, are considered benchmarks for optical data quality due to their traceability to international measurement standards. This paper describes the concept of a spacebased transfer calibration radiometer called the Satellite Cross-Calibration Radiometer (SCR) that would enable the calibration parameters from satellites such as Landsat-8/9, Sentinel-2, or other benchmark systems to be transferred to a range of commercial optical EO satellite systems while in orbit. A description of the key characteristics of the SCR to successfully operate in orbit and transfer calibration from reference systems to client systems is presented. A system like the SCR in orbit could complement SI-Traceable satellites (SITSats) to improve data quality and consistency and facilitate the interoperable use of data from multiple optical sensor systems for delivering higher returns on the global investment in EO.

Duketon, WA, 1994 (P613), radiometric line data, AWAGS levelled

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 Duketon, WA, 1994 (P613), radiometric line data, AWAGS levelled were acquired in 1994 by the WA Government, and consisted of 47160 line-kilometres of data at 400m line spacing and 80m 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.

Australian radiogenic granite and sedimentary basin geothermal hot rock potential map

The hot rock geothermal model in the Australian context comprises high-heat producing granites overlain by thick accumulations of low-thermal  conductivity sediments. The granites have low concentrations of radiogenic elements, and over hundreds of millions of years, these elements decay and produce heat. The passage of this heat to the Earth's surface via upwards conduction is slowed by layers of sediments that have low thermal conductivity, creating 'hot spots' beneath the blankets. This thematic map shows granites attributed by heat production and basin depth. The majority of the granites depicted are of surface outcrop. The presence of high-heat producing granites adjacent to deep sedimentary basins may be used as a first-order indicator of where to further investigate the possibility of hot rock geothermal plays.
The main frame of the map shows all granites (attributed by calculated heat production - where available), sedimentary basins (and their order e.g. where one basin is overlapped by another) and geothermal licences and applications. The top right inset map shows only those granites with a calculated radiogenic heat generation of &gt;5 uW -3, with the depth of the sedimentary basins. This map provides a rapid view of areas that may be expected to have the greatest hot rock potential. The second-from-top inset map shows all suitable geochemical analyses from OZCHEM, attributed by calculated radiogenic heat generation. This shows both the distribution of data that goes into attributing the granite polygons, and also analyses of granites (and other rocks) that fall outside the mapped granite polygons that are otherwise excluded from the main map. The third-from-top inset map shows the distribution of drillholes with temperature measurements. The bottom inset map shows an image of the Austherm07 database, which is derived from the drillhole temperature information. The image shows the projected temperature of the crust at a depth of 5 kilometres, interpolated between the drillholes. Overlain on this image is the small number of publicly-available heat flow data.

Evaluation of Gossans in Relation to Lead-Zinc Mineralisation in the Mount Isa Inlier, Queensland

Structural, textural, mineralogical, and geochemical properties of gossans associated with lead-zinc mineralisation in the Carpentarian Mount Isa Inlier of northwest Queensland have been studied. Mineralisation at Mount Isa, Hilton, and Lady Loretta is associated with abundant stratiform pyrite, which, upon oxidation, has formed prominent gossanous ridges at each deposit. The gossans, which have a laminated structure and occasional boxworks and casts after pyrite, generally carry only minor to trace levels of target and pathfinder elements. Where orebodies were close to the surface, cerussite and other secondary lead minerals are abundant, but Zn and Ag have been substantially leached from surface gossans. Immature gossans are found on the Dugald River and Pegmont dposits, both of which have low iron sulphide contents and a partially truncated profile. At Dugald River, the normally mobile elements (e.g. K , S, Zn, Cu, Cd, Tl) have been retained because of reaction between acid solutions and carbonate-rich wall rocks. The Pegmont mineralisation occurs in a quartz-magnetite-garnet-apatite banded iron formation, which, on oxidation, has given rise to a Mn-, Pb-, and Zn-rich gossan with abundant plumbogummite, pyromorphite, and coronadite. Gossans and ironstones from elsewhere within the Paradise Creek Formation, Soldiers Cap Group, Mount Isa Group, and Answer Slate often have similar laminated structures and mineralogy, but their variable geochemical signatures make direct comparison with other deposits difficult. Various statistical techniques have been used to evaluate these geochemical data in relation to gossans and ironstones of known association from throughout the Mount Isa Inlier. Although reflecting some known mineralogical and elemental associations, neither correlation coefficients nor R-mode factor analysis are of use in assigning group membership, because of the diverse geochemical characteristics of the ferruginous outcrops. Stepwise discriminant analysis using Pb, P, Ba, As, Zn, Mn, Co, S, and Sb was found to classify all gossans and ironstones into six geologically distinct groups.

North Bowen Basin region: Groundwater package

Publicly available groundwater data have been compiled to provide a common information base to inform environmental, resource development and regulatory decisions in the north Bowen Basin region. This data guide gives examples of how these data can be used. The data package included with this data guide captures existing knowledge of near-surface groundwater resources in north Bowen Basin, including salinity, water levels, resource size and surface water interactions. The methods used to derive these data for the shallow groundwater in the north Bowen Basin are outlined in the associated metadata files. These are described in groundwater conceptual models (Hostetler et al., 2023).
Groundwater data for the north Bowen Basin are restricted to the upper 50 m, as a stratigraphic model is not available. Compiled data are assigned to this interval and used to characterise the near-surface groundwater system at the basin scale.
The data are compiled for a point-in-time to inform decisions on potential resource developments in the Basin. The available historical groundwater data can be used to assess the potential effects on groundwater. The data can also be used for other purposes, such as exploring unallocated groundwater resource potential. Data to January 2022 are used for this compilation.
