TEISA - Area D (D1-D3), SA, 1999 (P853), radiometric line data, AWAGS levelled

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.

L052 Undilla Basin seismic survey, QLD, 1961

The Undilla Basin, in north-western Queensland, is a small sedimentary basin containing Cambrian limestones which adjoin the widespread but undated CamoowJal Dolomite to the West. In the latter
part of 1961 the Bureau of Mineral Resources, Geology and Geophysics did a brief reconnaissance seismic survey lasting about seven weeks in the Undilla Basin. This Record describes briefly the work done and results obtained. The occurrence of limestone near the surface throughout the basin presented difficult problems in the application of the reflection and refraction seismic methods but some progress was made towards the solution of these problems.

Carboniferous, Permian, and Triassic conchostracans of Australia : three new studies

The upper part of the Carboniferous Anderson Formation (late Visean to possibly early Namurian), in its type section (Grant Range No. I Well), contains five, possibly six, conchostracan genera: Leaia, Monoleaia, Rostroleaia, Limnadiopsileaia, Cyzicus, and possibly Ellipsograpla. The ribbed genus Hemicycloleaia Raymond is reassigned as a subgenuSi of Leaia, and seven new Carboniferous species are described: Leaia (Leaia) andersonae, Leaia (Hemicycloleaia) rectangellipla, Leaia (Hemicycloleaia) grantrangicus, Leaia (Hemicycloleaia) tonsa, Leaia (Hemicycloleaia) longicosta, Monoleaia australiata, and Limnadiopsileaia carboni/erae. The Lower Triassic Blina Shale, in scattered outcrops (Bell's Ridge, Erskine Hill, Wongil Ridge, Lake lones, and Minnie Range), and in Meda No. I Well, contains three conchostracan genera: Estheriina, Palaeolimnadia, and Cyzicus. Two new subgenera are established: Estheriina (Nudusia), and Palaeolimnadia (Grandilimnadia). Estheriina (Nudusia) is distinguished from E. (Estheriina) lones by the absence of growth bands on the umbonal area; and Palaeolimnadia (Grandilimnadia) is distinguished from P. (Palaeolimnadia) Raymond by its smaller umbonal area-without growth bands-relative to the entire valve, and its lower valve form (height/length) ratio. Four new Triassic species are described: Cyzicus (Lioestheria) erskinehillensis, Palaeolimnadia (Grandilimnadia) medaensis, and Estheriina (Nudusia) blina from the Canning Basin, and Palaeolimnadia (Grandilimnadia) mitchelli from the Sydney Basin. Belgolimnadiopsis allstralensis Novozhilov, present in the Triassic of both the Sydney and Canning Basins, is referred to the subgenus Cyzicus (Lioestheria). The only genus that persisted from the Carboniferous into the Triassic of the Canning Basin was CYZiCllS. Upper Permian palaeolimnadids from the Newcastle Coal Measures of the Sydney Basin were available for passive dispersal westward. The Knocklofty Formation of Tasmania, a correlate of the Blina Shale, also has a Palaeolimnadia-Cyzicus fauna.

Petroleum Geology of the Clarence-Moreton Basin

The Triassic to Jurassic rocks of Clarence-Moreton Basin contain abundant oil-proneorganic matter of terrestrial origin particularly in the Walloon Coal Measures and to a lesserextent in the Koukandowie Formation. This is reflected in petrographic composition, pyrolysisyields, elemental composition and extractable hydrocarbon yields. Maturation levels vary fromimmature to marginally mature in the west to overmature in the eastern part of the basin inNSW. Calculations based on Rock Eval data show that significant oil generation occurred ina narrow maturation range (0.8-1.0% vitrinite reflectance) and that migration has been highlyefficient. Potential reservoirs are present in quartzose sandstones in the KoukandowieFormation, Gatton Sandstone, Ripley Road Sandstone and Raceview Formations. Maturation modelling and fission track analyses indicate that hydrocarbon generation occurred in theperiod 80-100 Ma during a period of high heat flow when the Tasman Sea spreading ridgewas adjacent to the southeastern side of the Logan Sub-basin. Despite the abundance ofoil-prone source rocks, the basin is considered to be largely gas-prone because the drainageareas for most larger structural traps are overmature. The main difficulty in exploration ispredicting the distribution of porosity and permeability which varies because of bothdepositional facies and diagenesis, even in quartzose units.
The area with the greatest hydrocarbon prospectivity is the New South Wales part ofthe Logan Sub-basin which has gas potential throughout and a chance of minor oil discoveriesalong its western margin. The northern Logan Sub-basin has some prospectivity for oil andgas and the Laidley Sub-basin has minor prospectivity for oil in the Raceview Formation.

From offshore to onshore probabilistic tsunami hazard assessment via efficient Monte-Carlo sampling

Offshore Probabilistic Tsunami Hazard Assessments (offshore PTHAs) provide large-scale analyses of earthquake-tsunami frequencies and uncertainties in the deep ocean, but do not provide high-resolution onshore tsunami hazard information as required for many risk-management applications. To understand the implications of an onshore PTHA for the onshore hazard at any site, in principle the tsunami inundation should be simulated locally for every scenario in the offshore PTHA. In practice this is rarely feasible due to the computational expense of inundation models, and the large number of scenarios in offshore PTHAs. Monte-Carlo methods offer a practical and rigorous alternative for approximating the onshore hazard, using a random subset of scenarios. The resulting Monte-Carlo errors can be quantified and controlled, enabling high-resolution onshore PTHAs to be implemented at a fraction of the computational cost. 
This study develops novel Monte-Carlo sampling approaches for offshore-to-onshore PTHA. Modelled offshore PTHA wave heights are used to preferentially sample scenarios that have large offshore waves near an onshore site of interest. By appropriately weighting the scenarios, the Monte-Carlo errors are reduced without introducing any bias. The techniques are applied to a high-resolution onshore PTHA for the island of Tongatapu in Tonga. In this region, the new approaches lead to efficiency improvements equivalent to using 4-18 times more random scenarios, as compared with stratified-sampling by magnitude, which is commonly used for onshore PTHA. The greatest efficiency improvements are for rare, large tsunamis, and for calculations that represent epistemic uncertainties in the tsunami hazard.
To facilitate the control of Monte-Carlo errors in practical applications, this study also provides analytical techniques for estimating the errors both before and after inundation simulations are conducted. Before inundation simulation, this enables a proposed Monte-Carlo sampling scheme to be checked, and potentially improved, at minimal computational cost. After inundation simulation, it enables the remaining Monte-Carlo errors to be quantified at onshore sites, without additional inundation simulations. In combination these techniques enable offshore PTHAs to be rigorously transformed into onshore PTHAs, with full characterisation of epistemic uncertainties, while controlling Monte-Carlo errors.

Australia's Future Energy Resources project, the untapped potential of onshore low carbon energy resources

The “Australia’s Future Energy Resources” (AFER) project, funded under the Government’s “Exploring for the Future” (EFTF) program has been completed. The project’s four modules have evaluated a mixture of energy resource commodities, including natural gas, hydrogen, subsurface storage opportunities for carbon dioxide and hydrogen. They are complimented by several targeted basin inventories which outline the current geological knowledge of energy resources in underexplored, data-poor regions. Several publicly available data sets have been generated and published under the AFER project, including 3,750&nbsp;line-km of reprocessed 2D seismic data, acquired in the Pedirka and western Eromanga basins, of which key lines have been interpreted and integrated with geological and petrophysical well log data. Relative prospectivity maps have been produced for five energy resource commodities from 14&nbsp;play intervals to show the qualitative variability in prospectivity of these resources, including quantitative resource assessments where warranted. Results from the AFER project have helped to identify and geologically characterise the required energy resource commodities to accelerate Australia’s path to net zero emissions.
