The 2018 national seismic hazard assessment of Australia: Quantifying hazard changes and model uncertainties

Seismic hazard assessments in stable continental regions such as Australia face considerable challenges compared with active tectonic regions. Long earthquake recurrence intervals relative to historical records make forecasting the magnitude, rates and locations of future earthquakes difficult. Similarly, there are few recordings of strong ground motions from moderate-to-large earthquakes to inform development and selection of appropriate ground motion models (GMMs). Through thorough treatment of these epistemic uncertainties, combined with major improvements to the earthquake catalog, a National Seismic Hazard Assessment (NSHA18) of Australia has been undertaken. The resulting hazard levels at the 10% in 50-year probability of exceedance level are in general significantly lower than previous assessments, including hazard factors used in the Australian earthquake loading standard (AS1170.4–2007 [R2018]), demonstrating our evolving understanding of seismic hazard in Australia. The key reasons for the decrease in seismic hazard factors are adjustments to catalog magnitudes for earthquakes in the early instrumental period, and the use of modern ground-motion attenuation models. This article summarizes the development of the NSHA18, explores uncertainties associated with the hazard model, and identifies the dominant factors driving the resulting changes in hazard compared with previous assessments.

Tallaringa South - dose rate no nasvd grid (AWAGS)

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. The total dose rate is due to natural sources of radiation and is computed by adding estimates of cosmic dose at ground level to the terrestrial dose. The terrestrial dose rate grid is derived as a linear combination of the filtered K, U and Th grids. A low pass filter is applied to this grid to generate the filtered total dose rate grid. 
The Geological Survey of South Australia commissioned the Gawler Craton Airborne Survey (GCAS) as part of the PACE Copper initiative. The airborne geophysical survey was flown over parts of the Gawler Craton in South Australia. The program was designed to capture new baseline geoscientific data to provide further information on the geological context and setting of the area for mineral systems. 
This Tallaringa South - dose rate no nasvd grid (AWAGS) has a cell size of 0.0004 degrees (approximately 42m) and shows the total dose rate of the Tallaringa South Airborne Magnetic Radiometric and DEM Survey, SA, 2017 survey. The data used to produce this grid was acquired in 2017 by the SA Government, and consisted of 146285 line-kilometres of data at 200m line spacing and 60m terrain clearance.

Geochemical evidence for a new Triassic petroleum system in Australia - APPEA 2021

The unexpected discovery of oil in Triassic sedimentary rocks of the Phoenix South 1 well on Australia’s North West Shelf (NWS) has catalysed exploration interest in pre-Jurassic plays in the region. Subsequent neighbouring wells Roc 1–2, Phoenix South 2–3 and Dorado 1–3 drilled between 2015 and 2019 penetrated gas and/or oil columns, with the Dorado field containing one of the largest oil resources found in Australia in three decades. This study aims to understand the source of the oils and gases of the greater Phoenix area, Bedout Sub-basin using a multiparameter geochemical approach. Isotopic analyses combined with biomarker data confirm that these fluids represent a new Triassic petroleum system on the NWS unrelated to the Lower Triassic Hovea Member petroleum system of the Perth Basin. The Bedout Sub-basin fluids were generated from source rocks deposited in paralic environments with mixed type II/III kerogen, with lagoonal organofacies exhibiting excellent liquids potential. The Roc 1–2 gases and the Phoenix South 1 oil are likely sourced proximally by Lower–Middle Triassic TR10–TR15 sequences. Loss of gas within the Phoenix South 1 fluid due to potential trap breach has resulted in the formation of in-place oil. These discoveries are testament to new hydrocarbon plays within the Lower–Middle Triassic succession on the NWS.

A belemnite biozonation for the Jurassic-Cretaceous of Papua New Guinea and a faunal comparison with eastern Indonesia

Middle and Late Jurassic and some Early Cretaceous Belemnitida collected mostly within the region covered by the Ok Tedi and Mianmin 1:250 000 sheets in the central highlands of Papua New Guinea are identical with those of eastern Indonesia. Conodicoelites kalepuensis confirms that part of the Maril Formation is Bathonian in age. Members of the Belemnopsis moluccana-B. galoi-B. stolleyi lineage which spans the Late Jurassic of Indonesia confirm that the Imburu Mudstone and Upper Maril Formation are Oxfordian- Late Tithonian in age. Hibolithes australis n. sp. spans the Late Tithonian-earliest Berriasian interval; Belemnopsis jonkeri and Hibolithes gamtaensis n. sp. range from Berriasian to Valanginian confirming these ages for the Toro Sandstone, basal Ieru Formation and basal Tubu unit. Hibolithes taylori n. sp. (Aptian- Albian), Parahibolites jeraminensis n. sp. (Albian) and Dimitobelus macgregori (Albian- Cenomanian) are present in the Upper Ieru Formation and Chim Formation. The presence of Hibolithes taylori in outcrops previously mapped as Toro Formation suggests that the Aptian- Albian Omati Unit has been wrongly identified as Toro Formation in some instances.

The problem of inconsistency between thermal maturity indicators used for petroleum exploration in Australian basins

A major frustration in thermal maturation modelling for petroleum exploration in Australian sedimentary basins is the inconsistency between the values of different thermal maturity indicators.  Vitrinite reflectance (VR) , Rock-Eval Tmax , spore colouration index (SCI) and fluorescence alteration of multiple macerals (FAMM) for wells from three Australian basins show inconsistencies due to technical, methodological and conceptual problems inherent in each technique. When the differences between the concepts of rank and thermal maturity are considered, it can be shown that some inconsistencies are more apparent than real. It is important to consider this distinction when selecting data against which to model burial and thermal histories.

Seal capacity, composition and geochemistry of Adavale Basin rock salt

Large-scale storage of commercially produced hydrogen worldwide is presently stored in salt caverns. Through the Exploring for the Future program, Geoscience Australia is identifying and mapping salt deposits in Australia that may be suitable for hydrogen storage. The Boree Salt in the Adavale Basin of central Queensland is the only known thick salt accumulation in eastern Australia, and represent potentially strategic assets for underground hydrogen storage. The Boree Salt consists predominantly of halite and can be up to 555 m thick in some wells. 
Geoscience Australia contracted CSIRO to conduct analyses four Boree Salt whole cores extracted from Boree 1 and Bury 1 wells. The tests were carried out to determine the seal capacity (mercury injection capillary pressure - MICP), mineralogy (X-ray diffraction - XRD), and inorganic geochemistry of the cores. The entire core sections were scanned using X-ray CT images. In addition, four plugs were taken from the cores and tested for dry bulk density, grain density, gas porosity, and permeability. Two plugs underwent ultra-low permeability tests. The MICP test suggests that the Boree Salt is a competent seal for hydrogen storage. Mineralogy testing (XRD) revealed that the Boree Salt samples primarily comprise halite (96.5%), minor anhydrite (1.32%) and dolomite (1.65%) with traces of quartz, calcite, sylvite and cristobalite. Inorganic geochemistry results show sodium (Na; 55.4% average) is the most abundant element. Further tests, such as the creep test, in-situ seal capacity test, and leaching tests, are required to determine the suitability of the Boree Salt for underground hydrogen storage.
