AUSGeoid98 v.1.0 data files: Leonora (sh51-01)

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 Data format: AUSGeoid98 data files have a header record at the start of each file, to distinguish them from the superseded AUSGeoid93 data files. AUSGeoid98 data files show the geoid-ellipsoid separation to 3 decimal places, while the superseded AUSGeoid93 data files showed only 2 decimal places.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

Boola Boola Gravity (P195611), 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 Boola Boola Gravity (P195611) contains a total of 131 point data values acquired at a spacing of 250 metres. The data is located in VIC and were acquired in 1956, under project No. 195611 for Bureau of Mineral Resources (BMR).

Regional structure and evolution of the Redbank-Mount Zeil thrust zone: a major lineament in the Arunta Inlier, central Australia

The western part of the Arunta Inlier, central Australia, consists of major northward-tilted blocks separated by major thrust faults - the Anmatjira, Napperby, Redbank-Mount Zeil and Mount Sonder-Mount Razorback faults-associated with major Bouguer gravity anomalies. The Redbank-Mount Zeil thrust zone (RTZ) separates a granulite-facies suite to the north from a paragneiss-migmatite-orthogneiss suite to the south. This fault is marked by major radiometric, magnetic, and morphological discontinuities, and consists of northward-dipping protomylonite, mylonite, ultramylonite, and phyllonite, formed under a heterogeneous ductile shear- regime. Kernels of granulite, paragneiss, and migmatite abound. The RTZ truncates all other structures and postdates all juxtaposed units. Dynamothermal activity along the RTZ about 1000-900 Ma ago may be reflected by possibly reset Rb-Sr ages in blastoporphyritic gneisses and migmatite to the north and south, respectively. Major Palaeozoic movements are indicated by Devonian fanglomerate (Brewer Conglomerate), while younger reactivation is suggested by morphological features. Two alternative models are considered: (1) an antecedent of the RTZ formed an early boundary between an older igneous-dominated granulite block to the north and a younger amphibolite-facies paragneiss belt to the south prior to about 1600 Ma ago; or (2) contemporaneous granulite and paragneiss terrains representing different depth zones within a vertically zoned crust were allochthonously juxtaposed by the thrusting. The uplift of basic granulites along the RTZ is estimated from thermobarometric measurements to be at least 20 km, accounting for the Papunya Bouguer anomaly high of more than 500 Âµm/s2 . The emplacement of deep-seated basic intrusions, the ensuing geothermal rises, and crustal anatexis may have been genetically and temporally related.

NSW DMR, Discovery 2000, 1994-95, AREA B, Darling Basin West (P732), 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 NSW DMR, Discovery 2000, 1994-95, AREA B, Darling Basin survey were acquired in 1995 by the NSW Government, and consisted of 150000 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.

Reviewing the 1 March 1954 Adelaide Earthquake, South Australia

The 1 March 1954 earthquake in South Australia is the most damaging earthquake to impact the densely populated Adelaide region since European settlement. Previous interpretations have associated the event with the Eden-Burnside Fault zone, with a presumed epicentre near Darlington. Surprisingly, comparing macroseismic intensities from the 1954 earthquake with similar modern observational datasets suggests the 1954 event was perhaps larger than previously thought. We assess the validity of this observation by reviewing available macroseismic and instrumental data. We observe damaging shaking extending east from Adelaide into the Adelaide Hills, but without a well-defined locus of higher intensities. The limited teleseismic observations lead us to further speculate that the 1954 earthquake could have been deeper and/or associated with a higher-than-normal stress drop. These new findings question the conventionally assumed location for the 1954 earthquake. Our work highlights the potential seismic hazards faced by large urban centres in Australia such as Adelaide.
This paper was presented to the 2022 Australian Earthquake Engineering Society (AEES) Conference 24-25 November (https://aees.org.au/aees-conference-2022/)

Australian Hydrogen Projects and Research Centres Dataset (November, 2021)

This dataset features Australian hydrogen projects and research centres that are active in the development, construction, or operating phase, and meet renewable hydrogen or carbon capture and storage (CCS) hydrogen production methods outlined in Australia's National Hydrogen Strategy. This dataset aims is to provide a detailed snapshot of hydrogen activity across Australia. It includes location data, proponent details, and descriptions for all hydrogen projects and research centres listed. Additional data is included for hydrogen projects, such as the energy source for hydrogen production, the method of hydrogen production, and the amount of hydrogen to be produced per year. This dataset is the basis of the point-location map of active Australian hydrogen projects and research centres featured on the Australia Hydrogen Opportunities Tool (AusH2.ga.gov.au). AusH2 aims to attract investment in Australia’s hydrogen industry, providing high quality, free, online geospatial analysis tools and data for mapping and understanding Australia’s hydrogen potential. It hosts key national-scale datasets, such as locations of wind and solar resources and distribution of infrastructure, as well as the Hydrogen Economic Fairways Tool (HEFT) that maps the economic viability of hydrogen production in Australia. The user can examine both hydrogen production by electrolysis using renewable energy sources and fossil fuel produced hydrogen coupled with CCS. AusH2 was produced by Geoscience Australia for the Council of Australian Governments (COAG) Energy Council’s Hydrogen Working Group in 2019. Updates to this dataset since September 2020 are coordinated with research.csiro.au/HyResource

An open source modelling and Bayesian inversion package for surface magnetic resonance data

Surface magnetic resonance (SMR) techniques image subsurface water using the electromagnetic response of resonant hydrogen nuclei in water. Here we introduce the SMRPInv (Surface Magnetic Resonance Probabilistic Inversion) package, which couples a high-performance forward modeller for SMR data, and a Gaussian process based non-linear Bayesian inversion. Both the forward and inverse codes are part of the freely available, open source HiQGA (High Quality Geophysical Analysis) codebase written entirely in Julia. We summarise the relevant forward physics, the necessary data processing of free induction decay at an SMR sounding, followed by the estimation of subsurface water content with a non-linear parameterisation. Results are presented for synthetic inversions as well as field data from Western Davenport (Northern Territory). Comparisons are made against downhole logging data, together with results from a deterministic inversion of the same SMR soundings. Through this, we demonstrate that a probabilistic approach is key to conceptualising variability of subsurface water content.&nbsp;
