Wangaratta North South thorium grid geodetic

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 radiometric thorium grid has a cell size of 0.00042 degrees (approximately 42m) and shows thorium element concentration of the Wangaratta North-South merge, 1996-1997 in units of parts per million (or ppm). The data used to produce this grid was acquired in 1996 by the VIC Government, and consisted of 84782 line-kilometres of data at a line spacing between 200m and 400m, and 80m terrain clearance.

Seismic velocities in the North West Shelf Region, Australia, from near-vertical and wide-angle reflection and refraction studies

A significant limitation of conventional seismic reflection technology is that it poorly constrains seismic velocities in the deep part of the section. These velocities are needed for seismic migration, to convert from time to depth, and to estimate the likely rock composition at depth. Seismic observations at large offsets can compensate for this limitation. The Australian Geological Survey Organisation recorded high-quality refraction and wideangle reflection seismic data using ocean-bottom seismographs
(OBS) along 5 profiles on Australia's North West Shelf, to maximum offsets of 300 km. The OBS transects coincide with previously acquired deep-crustal seismic-reflection profiles.  Consequently, velocity information can now be derived from two independent data sets: common-depth point (near-vertical) reflection data and refraction/wide-angle reflection data.

This dataset is part of a broader survey carried out by EGS onboard the survey vessel RV Bold Explorer (RV BE) during the  SUBCO Subsea Cable Network (SSCN) cable route survey. 
The area is confined to the data within the Western Eyre Marine Park. The Survey team and client representative joined the RV Bold Explorer on 17th April 2024 at Fremantle Port,  Australia. Following the embarkation of the survey team, equipment testing and commissioning was carried out. Calibration and verification of the DGPS positioning system and survey gyros onboard RV BE were performed while the vessel was alongside at Fremantle Port, Australia between 17th April and 18th April 2024. 
Prior to departure, tow sensors and hull-mounted sensors were wet tested. All systems were found to be operational. The RV Bold Explorer departed Fremantle Port, Australia and transited to the first site on 19th April 2024. The offshore calibration of shallow water multibeam echosounder (MBES) and USBL were performed on 19th April 2024 while the  calibration of deep water MBES was carried out on 20th April 2024.
The SSCN Segment 2-B survey comprised an investigation of bathymetry, seabed features and shallow geology along the proposed route. A subsequent geotechnical sampling programme was also executed.
This dataset is not to be used for navigational purposes.

Deep structure offshore Eastern Australia from wide-angle seismic data: what controls crustal segmentation along the rifted oceanic basins and the Lord Howe Rise?

The eastern Australian margin was shaped during the fragmentation of eastern Gondwana in the Late Cretaceous. This led to the opening of the Tasman Basin and to the formation of sub-parallel ridges and basins, including the Lord Howe Rise. The driving forces controlling the rifting are not fully understood and two processes can be invoked: slab rollback associated with upper-plate extension  or a plume impinging on the lithosphere. However, the deep structure of the area is still unknown. In March-April 2016 using the R/V Kairei, the first large-scale crustal experiment of this region was conducted by JAMSTEC and Geoscience Australia with the deployment of 100 ocean-bottom seismometers (OBS) along a 680km profile at 27.2°S. The OBSs register clear refracted arrivals from the crust and the mantle that are recorded at very large offsets (up to 300km). The important variation in the offset of the triplication point between these two refracted arrivals suggests strong crustal thickness variation along the profile. We performed first-arrival tomographic inversion using two initial models with almost uniform lateral layering: (a) a four-layer model using the two-reflection  times from the basement interpreted from the multi-channel seismic data and (b) a five-layer model including a Moho interface, thereby allowing inversion of Moho reflections interpreted from the OBS data. The final tomographic Vp model confirms the strong variations in crustal thickness and allows the identification of distinct crustal domains along the profile: the Tasman Basin is an oceanic domain with 6 to 8km thick crust; further east a thicker crust is present below the Dampier Ridge (14km) where granitic rocks have been dredged; directly east of the Dampier Ridge the crust thins to 8km below the Middleton Basin, and the northern Lord Howe Rise is floored by a 23km thick crust. Below the northern Lord Howe Rise, lateral variations in upper-crustal velocities are observed with some areas showing higher velocities (Capel Basin) compared to the surrounding area (Faust Basin). These variations are associated with Moho relief at depth. We propose that these lateral variations can be explained by the prolongation of the SW-NE oriented Barcoo-Elisabeth-Fairway fracture zone, which is well-expressed in the Tasman Basin, through the northern Lord Howe Rise. Similar variations are observed towards the west below the Dampier Ridge where there are also variations in Moho depth. Based on these observations, we further suggest that the SW-NE-trending major fracture zones active during the opening of the Tasman Basin may have strongly controlled the latitudinal segmentation of the Lord Howe Rise, the Dampier Ridge and adjacent areas.

AUSGeoid98 v.1.0 data files:  (sl50-07)

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.

Cooper Basin region 3D map (Version 1) consisting of surfaces of buried granites and basin features

A 3D map of the Cooper Basin region has been produced over an area of 300 x 450 km to a depth of 20 km.  The 3D map was constructed from 3D inversions of gravity data using geological data to constrain the inversions.  It delineates regions of low density within the basement of the Cooper/Eromanga Basins that are inferred to be granitic bodies.  This interpretation is supported by a spatial correlation between the modelled bodies and known granite occurrences.  The 3D map, which also delineates the 3D geometries of the Cooper and Eromanga Basins, therefore incorporates both potential heat sources and thermally insulating cover, key elements in locating a geothermal play. This study was conducted as part of Geoscience Australia's Onshore Energy Security Program, Geothermal Energy Project.

GSQ Cloncurry ReducedToPole 1stVerticalDerivative 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 GSQ Cloncurry ReducedToPole 1stVerticalDerivative grid geodetic is the first vertical derivative of the TMI RTP grid of the Isa Region Airborne Magnetic Radiometric and DEM Survey, QLD, 2017 survey.
This grid has a cell size of 0.00018 degrees (approximately 19m) , and given in units of nT per metre (nT/m).  The data used to produce the TMI grid was acquired in 2017 by the QLD Government, and consisted of 113387 line-kilometres of data at 50m line spacing and 50m terrain clearance. The data has had a variable reduction to the pole applied to centre the magnetic anomaly over the magnetised body. The VRTP processing followed a differential reduction to pole calculation up to 5th order polynomial. Magnetic inclination and declination were derived from the IGRF-11 geomagnetic reference model using a data representative date and elevation representative of the survey. A first vertical derivative was calculated by applying a fast Fourier transform (FFT) process to the TMI RTP grid of the Isa Region Airborne Magnetic Radiometric and DEM Survey, QLD, 2017 survey to produce this grid. This grid was calculated using an algorithm from the INTREPID Geophysics software package. This grid shows the magnetic response of subsurface features with contrasting magnetic susceptibilities. The grid can also be used to locate structural features such as dykes.

National Geochemical Survey of Australia: Data Quality Assessment

Several quality control measures were taken during the project. These included:
- Central provision of sampling equipment and sample bags to all field teams
- Randomised sample identification scheme so that samples were presented to the laboratories in a sequence unrelated to the order in which they were collected (as much as practically feasible)
- Prevention of contamination in the field and in the lab
- Prevention of sample mix-up in the field and in the lab
- Field duplicates: every 10th site, a field duplicate sample was collected to help quantify total (sampling + analytical) precision (not identified as such to the lab)
- Certified Reference Materials (CRMs) TILL-1, TILL-2 (Natural Resources Canada) were run with every batch on GA's XRF &amp; ICP-MS to help quantify analytical precision and bias
- Laboratory duplicates (splits), internal project standards (MRIS, WRIS, ORIS, MRIS2, WRIS2), exchanged project standards (GEMAS-Ap, GEMAS-Gr from EuroGeoSurveys; SoNE-1 from United States Geological Survey), and international CRMs (TILL-1, TILL-3, LKSD-1, STSD-3 from Natural Resources Canada) were covertly inserted in the analytical suites for in-house and external analyses to help quantify analytical precision and bias (not identified as such to the lab)
- Internal project standard (GRIS) for pH 1:5, EC 1:5 and grain size measurements (not identified as such to the lab)
In addition to the above measures, the analytical labs applied their own QA/QC procedures, including running CRMs and/or internal standards, replicating digests and/or analysis, and analysis of blanks. 
The present report uses some of the above data to quantitatively assess the quality of the NGSA data, which allows a quality statement to be made about the NGSA data.
