Mapping the cover in northern Australia: towards a unified national 3D geological model

To meet the increasing demand for natural resources globally, industry faces the challenge of exploring new frontier areas that lie deeper undercover. Here, we present an approach to, and initial results of, modelling the depth of four key chronostratigraphic packages that obscure or host mineral, energy and groundwater resources. Our models are underpinned by the compilation and integration of ~200 000 estimates of the depth of these interfaces. Estimates are derived from interpretations of newly acquired airborne electromagnetic and seismic reflection data, along with boreholes, surface and solid geology, and depth to magnetic source investigations. Our curated estimates are stored in a consistent subsurface data repository. We use interpolation and machine learning algorithms to predict the distribution of these four packages away from the control points. Specifically, we focus on modelling the distribution of the base of Cenozoic-, Mesozoic-, Paleozoic- and Neoproterozoic-age stratigraphic units across an area of ~1.5 million km2 spanning the Queensland and Northern Territory border. Our repeatable and updatable approach to mapping these surfaces, together with the underlying datasets and resulting models, provides a semi-national geometric framework for resource assessment and exploration.

Duchess Gravity Traverse 1986 (P198601), 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 Duchess Gravity Traverse 1986 (P198601) contains a total of 364 point data values acquired at a spacing of 1000 metres. The data is located in QLD and were acquired in 1986, under project No. 198601 for None.

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The R502 series of maps has been replaced by the National Topographic Map Series (NTMS).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

AUSGeoid98 v.1.0 data files:  (se50-06)

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.

Prograde and retrograde sapphirine in metamorphic rocks of the central Arunta Block, central Australia

Sapphirine is a common mineral in silica-undersaturated rocks within the Mid-Proterozoic granulites of the Arunta Block in the northern Strangways Range, central Australia, and reactions involving sapphirine illustrate three episodes in the metamorphic evolution of the region. Prograde sapphirine-orthoclase-ortho-pyroxene assemblages occur as relics from the granulite stage (estimated P-T conditions 8 Â± I kb, 850-920Â°C).  In an early pervasive regional hydration, orthopyroxene-orthoclase-spinel assemblages reacted to form sapphirine-phlogopite or cordierite-phlogopite assemblages.  As the rocks cooled from the abnormally high geothermal gradient to a normal geothermal gradient, fine-grained intergrowths of orthopyroxene and sillimanite formed by reaction between sapphirine and cordierite.

Raw multibeam backscatter data of Jervis Bay

Geoscience Australia carried out marine surveys in Jervis Bay (NSW) in 2007, 2008 and 2009 (GA303, GA305, GA309, GA312) to map seabed bathymetry and characterise benthic environments through colocated sampling of surface sediments (for textural and biogeochemical analysis) and infauna, observation of benthic habitats using underwater towed video and stills photography, and measurement of ocean tides and wave generated currents. Data and samples were acquired using the Defence Science and Technology Organisation (DSTO) Research Vessel Kimbla. Bathymetric mapping, sampling and tide/wave measurement were concentrated in a 3x5 km survey grid (named Darling Road Grid, DRG) within the southern part of the Jervis Bay, incorporating the bay entrance. Additional sampling and stills photography plus bathymetric mapping along transits was undertaken at representative habitat types outside the DRG.
The "kimbla" folder contains raw multibeam backscatter data from four surveys archived seperately in 0303_jervis_trials, 0305_jervisbay2, 0311_jervisbay3 and 0313_jervis_trials4. The raw multibeam backscatter data were collected along survey lines using GAs Kongsberg SIMRAD EM3002 in single head and dual head configuration from aboard Work Boat Kimbla.

Helen Springs - Ucharonidge, NT, 1993 (P611), 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 Helen Springs/Beetaloo, NT, 1993 survey were acquired in 1993 by the NT Government, and consisted of 117753 line-kilometres of data at a line spacing between 300m and 300m, and 100m 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.

Analysing Australian geology, topography, and critical minerals using online datasets

This teacher guide and student activity resource uses map-based datasets found within the Geoscience Australia data portal (GA portal) to introduce critical minerals, strategic materials, and their relationship to geology and topography in Australia. This resource explains how to access datasets for surface geology, elevation, critical mineral and strategic material deposits and mine locations across Australia. The document includes an introduction to accessing and understanding each dataset, three case study examples of critical mineral and strategic material deposits in Australia, and mine operation concepts like extraction processes and end-of-mine rehabilitation and remediation. Each activity includes instructions on how to access and use the Geoscience Australia data portal as well as questions that prompt students to find, record, and interpret the data. Separate answer sheet is also provided.
The activities are suitable for use with secondary to senior secondary science and geography students.
