Geophysical Studies of Australia's Remote Eastern Deep-Water Frontier: Results from the Capel and Faust Basins

The Capel and Faust Basins in Australia's remote eastern offshore frontier, 800 km east of Brisbane in 1000-3000 m of water, are being studied as part of the Australian Government's Energy Security Initiative. A variety of geophysical data has been obtained and efforts are currently focussed on integrated interpretation of 2D seismic reflection data, sonobuoy refraction data and marine potential-field data. 
Negative residual gravity anomalies generally correlate with basins evident in the seismic reflection data. The anomalies highlight elongate, roughly N-S-trending or arcuate depocentres, with limited strike extent, that are best developed in the north and northwest of the survey area where increased crustal extension appears to have occurred. The 20-50 km separation between 2D seismic lines and the isolated nature of the basin depocentres complicates the process of linking structures between lines, but 3D mapping of faults and horizons is facilitated by the potential-field data. Instead of correlating with depocentres and basement highs, reduced-to-pole positive magnetic anomalies may reflect the distribution of volcanics and intrusives, variably evident as high-amplitude or low-frequency reflectors, and volcanic features at or near the seafloor. 
Interpretation of the seismic reflection data suggests the presence of four main syn-rift megasequence packages (?Early Cretaceous-?Santonian) and several post-rift sag packages (?Early Campanian-Recent). Maximum unequivocal depocentre thickness is ~4s TWT. Forward and inverse modelling of the gravity and magnetic data in 3D is providing a means to characterise different basement terranes and to construct surfaces that represent the sequence boundaries within the depocentres.

Tasman and Coral Seas bathymetry survey (FK201228/GA4868)

This resource includes bathymetry data acquired during the Tasman and Coral Seas survey using Kongsberg EM302 and EM710 multibeam sonar systems.
The Tasman and Coral Seas bathymetry survey (FK201228/GA4868); also known as Pinging in the New Year: Mapping the Tasman and Coral Seas survey; was led by James Cook University and University of Queensland  aboard the Schmidt Ocean Institute's research vessel Falkor from the 28th of December to the 25th of January 2021.
The primary objective of the expedition was to map the seabed of the target area in the Tasman and Coral Seas that will support ocean research, management and sustainable  economic development. Bathymetric maps are especially valuable for geoscience research, as the shape of the seafloor holds information about the tectonic movement and the formation of the Australian continent. 
Another objective was to survey seabirds, which are important indicators of ocean health and the data collected from the expedition are vital for informing management of the Coral Sea Marine Park.
 This V1 dataset contains one 64m resolution 32-bit floating point geotiff files of the Tasman and Coral Seas bathymetry survey area, derived from the processed EM302 and EM710 bathymetry data, using CARIS HIPS and SIPS software.
This dataset is not to be used for navigational purposes.
This dataset is published with the permission of the CEO, Geoscience Australia.

Tanami NS 4NE - TMI RTP grid (AWAGS)

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 magnetic grid has a cell size of 0.00018 degrees (approximately 20m).The data are in nanoTesla (or nT). The data used to produce this grid was acquired in 2018 by the NT Government, and consisted of 10063 line-kilometres of data at 100m line spacing and 60m terrain clearance. To constrain long wavelengths in the grid, an independent data set, the Australia-wide Airborne Geophysical Survey (AWAGS) airborne magnetic data, was used to control the base levels of the survey grid. This survey grid is essentially levelled to AWAGS.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.

Australian source rocks, fluids and petroleum systems – a new integrated geoscience data discovery portal for maximising data potential

Petroleum geochemical datasets and information are essential to government for evidence-based decision making on natural resources, and to the petroleum industry for de-risking exploration. Geoscience Australia’s newly built Data Discovery Portal (https://portal.ga.gov.au/) enables digital discoverability and accessibility to key petroleum geochemical datasets. The portal’s web map services and web feature services allow download and visualisation of geochemical data for source rocks and petroleum fluids, and deliver a petroleum systems framework for northern Australian basins. The Petroleum Source Rock Analytics Tool enables interrogation of source rock data within boreholes and field sites, and facilitates correlation of these elements of the petroleum system within and between basins. The Petroleum Systems Summary Assessment Tool assists the user to search and query components of the petroleum system(s) identified within a basin. The portal functionality includes customised data searches, and visualisation of data via interactive maps, graphs and geoscientific tools. Integration of the petroleum systems framework with the supporting geochemical data enables the Data Discovery Portal to unlock the value of these datasets by affording the user a one-stop access to interrogate the data. This allows greater efficiency and performance in evaluating the petroleum prospectivity of Australia’s sedimentary basins, facilitating and accelerating decision making around exploration investment to ensure Australia’s future resource wealth

Seal Distribution as a Constraint on the Limits of Petroleum Prospectivity: A Pilot Study from the Eyre Sub-basin in the Great Australian Bight

This report presents results from a pilot study conducted within the northern part of the Great Australian Bight, focusing primarily on the Eyre Sub-basin. The aim of the study was to develop and test a methodology for creating petroleum prospectivity maps based primarily on the extent of sealing lithologies. The Eyre Sub-basin provides a good basis for this study due to the good seismic coverage and lithological data provided from eight ODP holes and an Esso petroleum exploration well (Jerboa-1). Well data are used to determine which sequences contain potential sealing lithologies, while seismic data are used to map out the extent and distribution of potential sealing sequences across the study area. The regional extent of sealing units to their first pinch-out is used as a first-order assessment of petroleum prospectivity. Results from Jerboa-1 show that there is a proven oil source and adequate reservoir facies with seal and trap integrity being the major play risks.
Mesozoic sediments provide the primary potential sealing units across this region and have greatest thickness across the Eyre Sub-basin. To the west and north of this sub-basin, the distribution of the Mesozoic sediments is discontinuous, resulting in lower sealing potential. Mesozoic sediments are absent within the Eucla Inlier immediately north of the Eyre Sub-basin, resulting in very low sealing potential. Three categories of petroleum prospectivity have been determined in this study. Good prospectivity has been assigned up to the limits of the thick and continuous Mesozoic sediments in the Eyre Sub-basin. Low prospectivity has been assigned to the western Apollo Shelf, reflecting the reliance on relatively thin and discontinuous Mesozoic seals and the poor seal potential of Tertiary age carbonates. The Eucla Inlier is designated as a non-prospective area due to the absence of Mesozoic sediments and any potential sealing units for Tertiary age reservoirs.

Event chronology and prospectivity of the mafic magmatic systems in the Arunta Province

As part of the National Geoscience Agreement with the Northern Territory Geological Survey, Geoscience Australia is evaluating the geological setting of the mafic-ultramafic intrusions in the Arunta Province. The major aims of this study are to constrain the various mafic-ultramafic magmatic systems within the event chronology of the Arunta, and to provide a geoscientific framework for assessing the resource potential of the intrusions. 
SHRIMP U-Pb geochronology results of thirteen mafic-ultramafic bodies have highligted the episodic emplacement of the Arunta intrusions during the Proterozoic. Five major magmatic events from 1810 Ma to 1130 Ma have been identified. Geochemical discrimination diagrams show that the Arunta intrusions fall into two major geochemical groups that highlight geographical differences in prospectivity for Ni-Cu and platinum-group element mineralisation.
