Chlorine-36 measurements in the Murray Basin: preliminary results from the Victorian and South Australian Mallee region

36CI analyses of groundwater samples from 18 wells in the Victorian and South Australian Mallee region of the Murray Basin have been carried out using the technique of accelerator mass spectrometry.  Results of these analyses are discussed and presented as evidence for significant recharge from rainfall over much of the study area to the underlying Murray Group limestone aquifer.  In addition, results indicate areas where further 36CI measurements of Murray Mallee groundwater would provide useful hydrological information on both recharge and discharge mechanisms.

NSW DMR, Discovery 2000 Area L,Gilgandra, NSW, 1999 (P743), 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 NSW DMR, Discovery 2000 Area L,Gilgandra, NSW, 1999 survey were acquired in 1999 by the NSW Government, and consisted of 31389 line-kilometres of data at 250m 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.

Enhanced Oil Recovery Potential Basins WMS

This web map service shows the key Australian petroleum producing basins ranked by their potential for CO2 enhanced oil recovery (CO2-EOR), based on a study completed by Geoscience Australia in 2020. Basin rankings result from the assessment of six parameters: the API gravity of the oil, temperature, pressure, reservoir quality (porosity, permeability), nearby CO2 sources and existing infrastructure. Higher rankings indicate greater potential for CO2-EOR. For further information see: Tenthorey, E., and Kalinowski, A. 2022. Screening Australia’s Basins for CO2-Enhanced Oil Recovery.

Lake Edgar Earthquake Report

Several Quaternary fault scarps have been mapped in Australia during routine geological mapping. One of the most prominent scarps relates to the Lake Edgar Fault in southwest Tasmania. The 30km long north-south trending scarp occurs within the boundary of the Southwest National Park. The scarp traverses the button grass of the Huon Plains and is notable because faulting resulted in the defeat of westerly flowing drainage and the consequent formation of the fault-bound sag pond of Lake Edgar.

A two-part seabed geomorphology classification scheme; Part 2: Geomorphology classification framework and glossary (Version 1.0)

Maps of seabed geomorphology derived from bathymetry data provide foundational information that is used to support the sustainable use of the marine environment across a range of activities that contribute to the Blue Economy. The global recognition of the value of the Blue Economy and several key global initiatives, notably the Seabed 2030 project to map the global ocean and the United Nations Decade of Ocean Science for Sustainable Development, are driving the proliferation and open dissemination of these data and derived map products. To effectively support these global efforts, geomorphic characterisation of the seabed requires standardized multi-scalar and interjurisdictional approaches that can be applied locally, regionally and internationally. This document describes and illustrates a geomorphic lexicon for the full range of coastal to deep ocean geomorphic Settings and related Processes that drive the formation, modification and preservation of geomorphic units on the seabed. Terms and Settings/Processes have been selected from the literature and structured to balance established terminology with the need for consistency between the range of geomorphic Settings. This document also presents a glossary of the terms and identifies the insights that can be gained by mapping each unit type, from an applied perspective.

The 2003 Gawler Craton Seismic Survey: notes from the Seismic Workshop held at Gawler Craton State of Play 2004

Iron oxide-copper-gold (IOCG) systems, and their related magnetite-apatite systems, are suggested to form in orogenic belts (e.g., Cloncurry, Andean magmatic arc, Urals) and extensional settings (e.g., St FranÃ§ois Terrane, Missouri). Even so, the tectonic setting of arguably the most important of the IOCG class of the deposits, the giant world-class Olympic Dam deposit in South Australia, has been uncertain to date. It has previously been used as an example of the IOCG in an anorogenic intracontinental setting. The region has no outcrop as it is covered by Neoproterozoic sedimentary successions exceeding 5 km thick, in places. Given its economic significance and importance in defining the IOCG mineral deposit class, resolving the tectonic setting of Olympic Dam is crucially important. To address this, two orthogonal deep seismic reflection traverses, centred on the Olympic Dam deposit, were recorded to 18 s TWT.
The nearly north-south line, 193 km long, oriented as near to regional dip-direction, defined by potential-field data, as land access would allow, sounded units of the Archaean-Proterozoic Gawler Craton and a possible allochthanous Proterozoic terrane. The shorter east-west cross-line (57 km) provides control on the three dimensional geometry of the major structures and gives information about some out-of-plane structures imaged by the north-south traverse.
The seismic data show that the Olympic Dam deposit occurs in a fold- and thrust-belt, formed over a number of periods of orogeny, which was probably subject to compressional tectonics at the time of IOCG mineralisation. In the north of the study area, the upper crust, of the crystalline basement, shows south-dipping reflectors, interpreted as shear zones that cut through crust of sub-horizontal reflections. To the south, the upper crust and lower crust have reflectivity indicating thrusting to the south and, or, southwest, toward the interior of the Gawler Craton. However, the upper crustal deformation is decoupled from lower crustal deformation at a layer of sub-horizontal reflectors interpreted, by their reflection-amplitudes, to contain more mafic rocks than the regions above and below. This layer is up to 5 km thick and mostly un-deformed, except where it is duplexed. The duplexes appear to form the loci of strain partitioning in the upper crust. The lower crust of the centre of the study area contains fewer reflections, and appears anomalous but homogenised compared with the crust to the north and south.
Imaging of the cover-successions shows a previously unknown Adelaidean rift, which has been partially inverted.

AusSeabed Survey Coordination Tool GitHub Repository

The source code for the AusSeabed Survey Coordination Tool.
Code is located at: https://github.com/ausseabed/survey-request-and-planning-tool
The AusSeabed Survey Coordination tool (ASB SCT) is a tool designed by GA and FrontierSI in collaboration with the AusSeabed Steering Committee and broader community. Its intent is to provide a location for, and consistency in specification of bathymetric data acquisition for scientific research purposes. As of March 2022, the ASB SCT supports three key functions: 
1) Survey Planning: the ASB SCT allows the community to publicise their plans to survey in the Austrlian Marine Estate. The tool ingests a spatial outline of the intended location as well as the target data types and focus for the survey. The tool also collects the contact details for the chief investigator and anticipated survey dates. Once published, the survey plan is visible on the upcoming surveys spatial layer on the AusSeabed portal.
2) Hydroscheme Industry Partnership Program Requests: the ASB SCT hosts the online form for submitting survey requests to the Australian Hydrographic Office (AHO) for consideration by the HydroScheme Industry Partnership Programme.
3) Areas of Interest submission: the ASB SCT ingests submissions that describe a users seabed mapping or biodiversity characterisation data needs and location. This information is useful in identifying regions of mutual interest and boosting collaborative multi-disciplinary surveys. Understanding regions with high levels of overlapping data needs can also help inform high-value survey activities and legacy data release priorities.
