WMC Mount Fort Constantine Gravity (P199243), 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 WMC Mount Fort Constantine Gravity (P199243) contains a total of 4849 point data values acquired at a spacing between 100 and 1000 metres. The data is located in QLD and were acquired in 1992, under project No. 199243 for None.

Boorabbin 1:250 000 topographic map

This map is part of the series that covers the whole of Australia at a scale of 1:250 000 (1cm on a map represents 2.5 km on the ground) and comprises 513 maps. This is the largest scale at which published topographic maps cover the entire continent. Each standard map covers an area of 1.5 degrees longitude by 1 degree latitude or about 150 kilometres from east to west and 110 kilometres from north to south. There are about 50 special maps in the series and these maps cover a non-standard area. Typically, where a map produced on standard sheet lines is largely ocean it is combined with its landward neighbour. These maps contain natural and constructed features including road and rail infrastructure, vegetation, hydrography, contours (interval 50m), localities and some administrative boundaries. The topographic map and data index shows coverage of the sheets. Product Specifications Coverage: The series covers the whole of Australia with 513 maps. Currency: Ranges from 1995 to 2009. 95% of maps have a reliability date of 1994 or later. Coordinates: Geographical and either AMG or MGA (post-1993) Datum: AGD66, GDA94, AHD. Projection: Universal Traverse Mercator (UTM) Medium: Paper, flat and folded copies.

Pilbara, Hamersley, Bangemall Basins (Balfour Downs, Robertson, Bullen), WA, 1984 (P497), 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 Pilbara, Hamersley, Bangemall Basins (Balfour Downs, Robertson, Bullen), WA, 1984 survey were acquired in 1984 by the WA Government, and consisted of 40665 line-kilometres of data at 1500m line spacing and 150m terrain clearance.

The Camooweal seismic survey extends the known Carrara Sub-basin sedimentary packages

Under the Federal Governments’ Exploring for the Future (EFTF) program, Geoscience Australia (GA) recently acquired the Barkly and South Nicholson deep-crustal seismic reflection surveys (L212 and L210, respectively) in partnership with the Northern Territory Geological Survey (NTGS) and Geological Survey of Queensland (GSQ). The Barkly survey was completed in late 2019 as a collaboration between GA’s EFTF program and NTGS’s Resourcing the Territory initiative. Acquisition started at the Queensland-Northern Territory border near the town of Camooweal. It is comprised of five lines; 19GA-B1 (434.6 km), 19GA-B2 (45.9 km), 19GA-B3 (66.9 km), 19GA-B4 (225.8 km), and 19GA-B5 (39.4 km) (Southby et al., 2021), and was acquired via vibroseis using a nodal geophone system (Fomin et al., 2020), and links into the South Nicholson survey acquired in 2017. In 2019, the Camooweal deep-crustal seismic reflection survey (GSQ Open Data Portal 95590) was acquired by the GSQ as part of the Queensland Government's Strategic Resources Exploration Program (SREP), and was centred on the northwest Queensland town of Camooweal with the total length of acquisition spread over three lines; 19Q-C1 (65.8 km), 19Q-C2 (173.6 km) and 19Q-C3 (60.9 km). The Camooweal survey was acquired via vibroseis using a nodal geophone system and links to the South Nicholson and Barkly surveys (Edwards, 2020).
These seismic surveys have improved our understanding of the basins, basement structures and structural evolution of the region. They tie the underexplored region with the more explored and highly prospective McArthur and Mount Isa Province, in which there are now new areas identified for future exploration. The known, mappable extent of the South Nicholson Basin has been increased significantly and a new, potentially Proterozoic age, depocentre, the Carrara Sub-basin, located in the south east of South Nicholson region, has been discovered (Henson et al., 2018; Carr et al., 2019; Carson et al., 2020; MacFarlane et al., 2020). The Carrara Sub-basin is interpreted to include strata equivalent in age to the Isa Superbasin, South Nicholson Group, and the Georgina Basin (Carr et al., 2020) and current work on the NDI Carrara 1 drill hole will further constrain the stratigraphy and geology of the South Nicholson region; providing well control to the extensive network of new deep-crustal seismic acquired in this highly prospective frontier province. The aim of this study is to show the extent of the Carrara Sub-basin sedimentary packages by mapping the lateral extent of sedimentary sequences using seismic data interpretation.

AUSGeoid98 v.1.0 data files: Augusta (si50-09)

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.

LANDSAT: developing techniques and applications in mineral and petroleum exploration

The extensive research into satellite data technology that followed the launch of Landsat-1 (ERTS-1) in 1972 has resulted in progressive improvements to product quality and digital data analysis techniques. Improved image quality has direct significance to the many mineral and petroleum exploration organisations that are now routinely applying conventional photogeological interpretation techniques to Landsat multispectral scanner imagery. Photogeological techniques will continue to be the main means of Landsat interpretation, however, even the best quality imagery may contain less than one quarter of the total data recorded and computer techniques offer the only adequate means of analysing all the data in a Landsat scene. Considerable progress has been made with computer analysis of Landsat digital data and some techniques have definite application to mineral and petroleum exploration. In specific environments direct detection of iron weathering products associated with both hydrothermal alteration and uranium deposits has been achieved. Various computer-enhancement techniques have also been employed to reveal structural and lithological information not obvious on conventional Landsat imagery or aerial photography.

Use of high performance computing and high performance data in magnetotelluric data processing and inversion

Geoscience Australia (GA) has had an ongoing magnetotelluric (MT) program for over a decade. The software available for processing, analysis and inversion of MT data have evolved significantly over this time, partly to make use of increased availability of high performance computing facilities.
GA is a major contributor to the Australian Lithospheric Architecture Magnetotelluric Program (AusLAMP), which aims to collect long period MT data on a 0.5 degree grid across the Australian continent. Data and resistivity models from this program will image the Australian lithospheric conductivity from depths of 10 to 100 km. Given the continental scale and large number of stations being collected, inverting these data to obtain resistivity models of the Australian lithosphere relies on the use of specialised software on high performance computing facilities.
GA is also working to increase accessibility and useability of raw (time series) MT data. To date, large data volumes and inconsistent formats have limited the accessibility of this data. This has meant that it has been difficult to record a transparent workflow from raw to processed data, and then from processed data to modelling and inversion products. GA is working to make use of high performance data formats to facilitate the accessibility and visualisation of this data.
This presentation will detail some of the MT work being done by GA and how the availability of high performance computing facilities is helping to increase the impact and use of MT as a key dataset for understanding the Australian lithosphere.

Lagrange 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.
