Australia-wide 3D Density and Magnetic Susceptibility Models: Method and Model Release

Two coincident, crustal-scale models, one of magnetic susceptibility and one of density, have been produced for a volume covering the Australian continent and extending down to 55.5 km depth. These models were produced using the UBC GIF MAG3D and GRAV3D inversion programs, respectively.
The inversions were constrained with geological reference models with layers for sediments, undifferentiated crust and the mantle. The reference model for the magnetic inversion incorporated a Curie depth surface below which magnetic susceptibility was set to zero.
Due to the size of the inversion problem to be solved, the volume was divided into 235 overlapping inversions, which were inverted separately and then recombined. The method of recombining the inversions relies on a cosine function to determine the weight of each property and then takes a weighted average. This method successfully attenuated the edge effects that would otherwise occur between models and allows them to be viewed as one seamless model that covers the whole of Australia.
Regions of coincident high-density (&gt;2.83 g/cm3) and high-magnetic susceptibility (&gt;0.0125 SI) within the top 10 km of the undifferentiated crust (termed magnetite proxies) are suggested to be related to ultramafic rocks and the magnetite-forming hydrothermal alteration stages of potentially fertile IOCG systems (see download link: Magnetite region grids) .

Magnetic Anomaly Map of Australia, Seventh Edition, 2020 - Enhanced Products Package - upward continued image (UC4km8kmRes)

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 2019 Total magnetic Intensity (TMI) grid of Australia has a grid cell size of ~3 seconds of arc (approximately 80 m). This grid only includes airborne-derived TMI data for onshore and near-offshore continental areas. Since the sixth edition was released in 2015, data from 234 new surveys have been added to the database, acquired mainly by the State and Territory Geological Surveys. The new grid was derived from a re-levelling of the national magnetic grid database. The survey grids were levelled to each other, and to the Australia Wide Airborne Geophysical Survey (AWAGS), which serves as a baseline to constrain long wavelengths in the final grid. It is estimated that 33 500 000 line-kilometres of survey data were acquired to produce the 2019 grid data, about 2 000 000 line-kilometres more than for the previous edition. 
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 Magnetic Anomaly Map of Australia, Seventh Edition, 2020 - Enhanced Products Package - upward continued image (UC4km8kmRes) is a pseudocolour image of the TMI grid of the Magnetic Anomaly Map of Australia, Seventh Edition, 2019.
This grid has a cell size of 0.00083 degrees (approximately 88m). This pseudocolour image shows the magnetic response of subsurface features with contrasting magnetic susceptibilities. The image can also be used to locate structural features such as dykes.

Seabed environments and shallow geology of the Vlaming sub-basin, Western Australia: Inorganic elements of seabed sediments.

Geoscience Australia undertook a marine survey of the Vlaming Sub-basin in March and April 2012 to provide seabed and shallow geological information to support an assessment of the CO2 storage potential of this sedimentary basin. The survey was undertaken under the Australian Government's National CO2 Infrastructure Plan (NCIP) to help identify sites suitable for the long term storage of CO2 within reasonable distances of major sources of CO2 emissions. The Vlaming Sub-basin is located offshore from Perth, Western Australia, and was previously identified by the Carbon Storage Taskforce (2009) as potentially highly suitable for CO2 storage. The principal aim of the Vlaming Sub-basin marine survey (GA survey number GA334) was to look for evidence of any past or current gas or fluid seepage at the seabed, and to determine whether these features are related to structures (e.g. faults) in the Vlaming Sub-basin that may extend up to the seabed. The survey also mapped seabed habitats and biota in the areas of interest to provide information on communities and biophysical features that may be associated with seepage. This research addresses key questions on the potential for containment of CO2 in the Early Cretaceous Gage Sandstone (the basin's proposed CO2 storage unit) and the regional integrity of the South Perth Shale (the seal unit that overlies the Gage Sandstone). This dataset comprises a suite of major and minor inorganic elements from seabed (0-2 cm) sediments.

Impact structures as potential petroleum exploration targets: Gosses Bluff, a Late Jurassic example in central Australia

Gosses Bluff, a prominent complex annular structure in central Australia, was produced by hypervelocity impact during the Late Jurassic. The impact occurred in the thick sedimentary succession close to the centre of a major sub-basin within the Amadeus Basin. The structure is well exposed and has good subsurface control as a consequence of earlier unsuccessful hydrocarbon exploration programs.  It provides an opportunity to study the effects of impact on a sedimentary succession without basement involvement, and to evaluate the potential of such structures as hydrocarbon plays.  Seismic data across the structure show that the original crater was 24 km in diameter, suggesting that originally a major ejecta blanket extended for at least 60 km beyond the rim. The underlying Neoproterozoic and Palaeozoic sedimentary rocks of the Amadeus Basin have been deformed to depths of several kilometres. Uplift at the centre of the Gosses Bluff structure is especially pronounced owing to rebound of the primary shock wave from the upper surface of the evaporites of the Bitter Springs Formation.  The thermal effects of impact on outcrop and core samples have been studied from apatite fission-track analysis (AFTA). Samples from the crater floor and remnant crater fill indicate that no significant fission-track annealing has occurred in response to the impact. All samples preserve tracks that were formed before the impact (~140 Ma) and are consistent with the regional thermal history. AFTA data from central uplift samples indicate that the main thermal effect of impact was not heating, but cooling related to exhumation.  Results have shown that, whereas shock-related fracturing enhanced porosity and permeability of underlying reservoir units to some extent, quartz cementation associated with impact reduced overall reservoir quality. The only potential hydrocarbon play, as yet untested, is the rim anticline formed beneath the crater rim as a response to post-impact salt migration.  Ultimately, the major factor that limits the petroleum potential of the Gosses Bluff structure is the timing of events. The impact occurred too late in basin evolution for an effective seal to be deposited over the structure. Further, the structure formed at about 140 Ma, whereas petroleum was probably generated before 200 Ma. Thus, any hydrocarbons trapped in the structure probably represent migration from pre-impact accumulations. In spite of the limited petroleum potential at Gosses Bluff, it does provide an important analogue for buried impact structures with more favourable thermal histories.
