Macdonald (Jolly Peaks), WA, 1993 (P618), 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 Macdonald (Jolly Peaks), WA, 1993 survey were acquired in 1993 by the WA Government, and consisted of 76950 line-kilometres of data at 400m line spacing and 60m 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.

A teleseismic travel time residual map of the Australian continent

Teleseismic travel time residuals for 43 seismic observatories and 6 networks of portable seismographs have been combined to produce a contour map of residuals for the Australian continent. Travel times to the shield regions of central and western Australia are low compared with average global travel times, indicating relatively high velocities in the upper mantle. The lowest times occur in the Archaean shield regions of Western Australia, the Proterozoic terranes in central Australia and the Gawler Block in South Australia, where heat flow is generally below world average. The residuals become progressively higher (arrival times later) towards the southeast, and the largest residuals are in Tasmania. The positive residuals indicate low velocities in the upper mantle, consistent with the predicted low velocity layer in the upper mantle under southeastern Australia, and higher observed heat flow.

Childara - U equivalent concentration grid (AWAGS, nasvd)

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.
This radiometric uranium grid has a cell size of 0.0004 degrees (approximately 41m) and shows uranium element concentration of the Childara Airborne Magnetic Radiometric and DEM Survey, SA, 2017 in units of parts per million (or ppm). The data used to produce this grid was acquired in 2017 by the SA Government, and consisted of 135047 line-kilometres of data at 200m 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.

A Geochemical Overview of Some Gippsland Basin Hydrocarbon Accumulations

In the 50 years since the first commercial discovery in 1965 at Barracouta-1, and 46 years since production commenced from the Barracouta field, a total of 16.5 TCF of gas, 4026 MMbbl of oil, 385 MMbbl of condensate and 752 MMbbl of LPG have been found in the Gippsland Basin (Estimated Ultimate Recovery, as at the end of 2012). Despite these extensive resources, all from CretaceousPaleogene Latrobe Group reservoirs, there are questions regarding the effective petroleum systems, contributing source rock units, and the migration pathways between source and reservoir. Resolution of these uncertainties is essential to improve our understanding of the remaining prospectivity and for creating new exploration opportunities, particularly in the eastern, less explored part of the basin, but also for mitigating risk for the potential sequestration of carbon dioxide along the southern and western flanks.
Geochemical fingerprinting of reservoir fluids has identified that the oil and gas originate from multiple sources. The most pervasive hydrocarbon charge into the largely produced fields overlying the Central Deep has a terrestrial source affinity, originating from lower coastal plain facies (Kingfish, Halibut, Mackerel), yet the oils cannot be correlated using source-related biomarker parameters to source rocks either within the Halibut Subgroup (F. longus biozone) at Volador-1, one of the deepest penetrations of the Upper Cretaceous section, or to older sections, penetrated on the flanks of the basin. However, within the underlying SantonianCampanian Golden Beach Subgroup an oil-source correlation has been established between the Anemone-1A oil and the marginal marine Anemone Formation (N. senectus biozone) at Anemone-1/1A and Archer-1. A similar correlation is indicated for the Angler-1 condensate to the Chimaera Formation (T. lilliei biozone) in the deepest section at Volador-1 and Hermes-1. In the Longtom field, gas reservoired within the Turonian Emperor Subgroup, potentially has a source from either the lacustrine Kipper Shale or the Albian portion of the Strzelecki Group. The molecular and carbon isotopic signatures of oil and gas from the onshore Wombat field are most similar to hydrocarbons sourced from the AptianAlbian Eumeralla Formation in the Otway Basin, also implicating a Strzelecki source in the Gippsland Basin. These results imply that sediments older than the Paleocene are significant sources of petroleum within the basin.

Carbon Isotopic Data of Bitumen and Kerogens in NDI Carrara 1, Northern Territory, Australia Data Release

Geoscience Australia’s Exploring for the Future program provides precompetitive information to inform decision-making by government, community and industry on the sustainable development of Australia's mineral, energy and groundwater resources. By gathering, analysing and interpreting new and existing precompetitive geoscience data and knowledge, we are building a national picture of Australia’s geology and resource potential. This leads to a strong economy, resilient society and sustainable environment for the benefit of all Australians. This includes supporting Australia’s transition to a low emissions economy, strong resources and agriculture sectors, and economic opportunities and social benefits for Australia’s regional and remote communities. The Exploring for the Future program, which commenced in 2016, is an eight year, $225 m investment by the Australian Government. 
As part of this program, Geoscience Australia led two deep crustal reflection seismic surveys in the South Nicholson region, revealing the existence of the Carrara Sub-basin, a large sedimentary depocentre up to 8 km deep, beneath the Georgina Basin (Carr et al., 2019; 2020). The depocentre is believed to contain thick sequences of highly prospective Proterozoic rocks for base metals and unconventional hydrocarbons. To confirm geological interpretations and assess resource potential, the National Drilling Initiative, NDI Carrara 1 stratigraphic drill hole was completed in late 2020, as a collaboration between Geoscience Australia, the Northern Territory Geological Survey (NTGS) and the MinEx CRC (Geoscience Australia, 2021). NDI Carrara 1 is located on the western flank of the Carrara Sub-basin on the South Nicholson seismic line (17GA-SN1) (Figure 1.1; Figure 1.2), reaching a total depth of 1751 m, intersecting sedimentary rocks comprising ca. 630 m of Cambrian calcareous shales of the Georgina Basin and ca. 1100 m of Proterozoic carbonates and siliciclastics that include black shales of the Carrara Sub-basin.
This report presents data on selected rock samples from NDI Carrara&nbsp;1, conducted by the Mawson Analytical Spectrometry Services, University of Adelaide, under contract to Geoscience Australia. These results include bulk carbon isotope ratios (δ13C) of bitumens and isolated kerogens. In addition, a selection of 10 samples was analysed at Geoscience Australia for comparison purposes.

Pyrite chemistry from key mineral prospects in the Delamerian

The Cambrian-Ordovician Delamerian Orogen formed during the transition from a passive margin setting during the rifting of Rodinia, to an active subduction margin along the eastern margin of Gondwana (Folden et al., 2006; Gilmore et al., 2023). It is spatially and temporally extensive, covering five states in central and eastern Australia, and extended to Antarctica. The area is largely underexplored, however resource potential has been demonstrated through the presence of numerous mineralising systems, particularly along the eastern margin. These mineralising systems include porphyry-epithermal, volcanic hosted massive sulfide (VHMS), orogenic gold and mafic-ultramafic copper-nickel-platinum group element (Cu-Ni-PGE) mineral systems (Cheng et al., 2024). 
Trace element analysis of pyrite via Laser Ablation Inductively Coupled Plasma Mass Spectrometry (LA-ICP-MS) can be used to reconstruct the conditions of pyrite formation in complex mineral systems. This project assesses the pyrite from the key prospects of multiple types of mineral systems across the Delamerian in South Australia, Victoria and New South Wales. Pyrite samples have been collected from various porphyry Cu-Au, VHMS, orogenic gold and orthomagmatic Ni-Cu-PGE prospects to gain a better understanding of these systems in the Delamerian. Additionally, samples from several metallogenetically undefined mineral prospects in Delamerian have been analysed to compare their metallogenic characteristics with these of known systems. These results will provide a new understanding of the mineral potential of the Delamerian Orogen, aiding mineral exploration in the region.
