Noble Gas Isotopes of Natural Gases from the Onshore Canning Basin, Western Australia. Data Release

The onshore Canning Basin in Western Australia was the focus of a regional hydrocarbon prospectivity assessment undertaken by the Exploring for the Future&nbsp;(EFTF) program dedicated to increasing investment in resource exploration in northern Australia, with the objective being to acquire new data and information about the potential mineral, energy and groundwater resources concealed beneath the surface. Significant work has been carried out to deliver new pre-competitive data in the region including new seismic acquisition, drilling of a stratigraphic well, and geochemical analysis from historic exploration wells.

As part of this program, determination of the molecular and noble gas isotopic composition of natural gases from selected petroleum wells in the Canning Basin were undertaken by Smart Gas Sciences, under contract to Geoscience Australia, with results from these analyses being released in this report. This report provides additional data to determine the sources of natural gases in the Canning Basin and build on the availability of existing gas data, gas-gas correlations and gas-oil correlations. Noble gas isotopic data can be used in conjunction with carbon and hydrogen isotopic data to determine the origin of both inorganic and organic (hydrocarbon) gases. This information can be used in future geological programs to determine the source and distribution of hydrogen and helium in natural gases and support exploration programs.

Carboniferous and early Permian brachiopods from Western and Northern Australia

Most of the Carboniferous brachiopods (excepting productoids and rhynchonellids) so far collected from the Carnarvon, Canning (Fitzroy), and Bonaparte Gulf Basins of Northwest Australia are described. The faunas of the Bonaparte Gulf Basin are the least well represented. Six Carboniferous brachiopod zonal assemblages are distinguished: two of Tournaisian, one of late Tournaisian. to possibly Visean, two of Visean and one of late Visean to possibly Namurian age. The described faunas include species of Rhipidomella, Leptagonia, Schellwienella, Schuchertella, Rugosochonetes?, Prospira, Unispirifer, Spirifer, Anthracospirifer, Ectochoristites?, Brachythyris, Kitakamithyris, Torynifer?, Syringothyris, Punctospirifer, Cleiothyridina, Composita, and an unnamed new spiriferid genus. At least 23 species are new. Affinities with world-wide Dinantian faunas are suggested for the majority. The brachiopods are distributed through the Moogooree Limestone and Yindagindy Formations of the Carnarvon Basin, the Laurel Formation of the Fitzroy Basin, and the Burt Range Formation, Enga Sandstone, Septimus Limestone, Utting Calcarenite, Burvill Beds and Point Spring Sandstone of the Bonaparte Gulf Basin. Four Permian spiriferacean species are also described from the Carnarvon and Canning Basins. They comprise the Sakmarian Lyons Group species Trigonotreta narsarhensis occidentalis subsp. nov., and Cyrtella nagmargensis australis subsp. nov., and the Artinskian Pseudosyringothyris dickinsi sp. novo from the Callytharra Formation and Pseudosyrinx? sinuosa sp. novo from the Madeline Formation. The species support a correlation of the Lyons Group with the Umaria beds of India, part of the Agglomeratic Slate of Kashmir, and early Permian beds of Arabia. Boreal affinities are suggested for P. dickinsi sp. Novo Generic morphological features are discussed. Points of interest include the composite nature of the dental plates in Schellwienella, the initial dental plates of certain Spiriferidae, the adductor muscle attachment function of the syrinx in Syringothyris and the adductor muscle scars on the delthyrial plate in Pseudosyringothyris. The taxonomy of certain families is discussed, notably the Syringothyridae.

SIFRA (System for Infrastructure Facility Resilience Analysis)

SIFRA is the acronym for 'System for Infrastructure Facility Resilience Analysis'. The  system provides an analytical approach for modelling the vulnerability of high-value infrastructure facilities by taking into consideration the fragilities and configurations of its constituent components. In doing this it uses a network theory based approach for modelling the facility and its operations. This method makes it possible to consider the discrete component-level vulnerabilities within a facility and, significantly, their system-level operational implications to the composite facility fragility. SIFRA also includes tools for modelling system restoration times under varied levels of resource allocation scenarios, and for identifying component criticality.

Lower Ordovician conodonts from the Bonaparte Gulf Basin and the Daly River Basin, northwestern Australia

This Bulletin describes the sequence of conodont species in the early Ordovician sediments of the Bonaparte Gulf Basin and the Daly River Basin, northwestern Australia (Fig. 1). The assemblage zones erected by Druce, Jones (1971) for the Lower Ordovician (Tremadocian) of western Queensland are recognized in the Bonaparte Gulf Basin. They are used to correlate the Lower Ordovician sediments both within the Bonaparte Gulf Basin, and between it, the Daly River Basin, and western Queensland. Intercontinental correlations are made on the basis conodonts previously described from Asia, North America, and Europe.

Barite, BIFs and Bugs: Implications to the Evolution of the Earth's Early Hydrosphere and its Implications for Mineral Deposits

The presence of relatively abundant bedded sulfate deposits before 3.2 Ga and after 1.8 Ga, the peak in iron formation abundance between 3.2 and 1.8 Ga, and the aqueous geochemistry of sulfur and iron together suggest that the redox state and the abundances of sulfur and iron in the hydrosphere varied widely during the Archean and Proterozoic. We propose a layered hydrosphere prior to 3.2 Ga in which sulfate produced by atmospheric photolytic reactions was enriched in an upper layer, whereas the underlying layer was reduced and sulfur-poor. Between 3.2 and 2.4 Ga, sulfate reduction removed sulfate from the upper layer, producing broadly uniform, reduced, sulfur-poor and iron-rich oceans. As a result of increasing atmospheric oxygenation around 2.4 Ga, the flux of sulfate into the hydrosphere by oxidative weathering was greatly enhanced, producing layered oceans, with sulfate-enriched, iron-poor surface waters and reduced, sulfur-poor and iron-rich bottom waters. The rate at which this process proceeded varied between basins depending on the size and local environment of the basin. By 1.8 Ga, the hydrosphere was relatively sulfate-rich and iron-poor throughout. Variations in sulfur and iron abundances suggest that the redox state of the oceans was buffered by iron before 2.4 Ga and by sulfur after 1.8 Ga.

Magnetic Anomaly Map of Australia, Seventh Edition, 2020 - Enhanced Products Package - TMI RTP image (PSusp)

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 2019 national 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 - TMI RTP image (PSusp) 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.
