Magnetic Anomaly Map of Australia, Seventh Edition, 2020 - Enhanced Products Package - vBzz grid

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 0.00083 degrees (approximately 88m).The data are in nanoTesla per metre (or nT/m). 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-15 geomagnetic reference model using a data representative date and elevation representative of the survey. A further enhancement has been completed to enhance the geological interpretation of the data.

Seabed Habitats and Hazards of the Joseph Bonaparte Gulf and Timor Sea, Northern Australia

The Joseph Bonaparte Gulf and Timor Sea region (JBG-TS) is an area of significance for multiple resource needs, from marine planning to offshore industry development. As such, information on seabed environments in this region is of interest to both industry and marine management. Geoscience Australia is focussed on the collation and preparation of regional pre-competitive environmental datasets, the outputs of which can be used for pre and post-bid environmental assessments and for emergency response planning.
This report provides a spatial synthesis of seabed environments for the Joseph Bonaparte Gulf and Timor Sea region (JBG-TS) by identifying and describing significant habitats, communities, and potential geohazards. Data are sourced from existing literature, including publicly available industry data, as well as data collected from two seabed mapping surveys to the Van Diemen Rise in the eastern Timor Sea (GA-322 and GA-325).

Convergent margin metallogenic cycling in the Eastern Goldfields Superterrane and Tasman Element

Over 900 Australian mineral deposits, location and age data, combined with deposit classifications, have been used to assess temporal and spatial patterns of mineral deposits associated with convergent margins and allow assessment of the potential of poorly exposed or undercover mineral provinces and identification of prospective tracts within known mineral provinces. Here we present results of this analysis for the Eastern Goldfields Superterrane and the Tasman Element, which illustrate end-members of the spectrum of convergent margin metallogenic provinces. Combining our Australian synthesis with global data suggest that after ~3000 Ma these provinces are characterised by a reasonably consistent temporal pattern of deposit formation, termed the convergent margin metallogenic cycle (CMMC): volcanic-hosted massive sulfide – calc-alkalic porphyry copper – komatiite-associated nickel sulfide → orogenic gold → alkalic porphyry copper – granite-related rare metal (Sn, W and Mo) – pegmatite. Between ca 3000 Ma and ca 800 Ma, virtually all provinces are characterised by a single CMMC, but after ca 800 Ma, provinces mostly have multiple CMMCs. We interpret this change in metallogeny to reflect secular changes in tectonic style, with single-CMMC provinces associated with warm, shallow break-off subduction, and multiple-CMMC provinces associated with modern-style cold, deep break-off subduction. These temporal and spatial patterns can be used to infer potential for mineralisation outside well-established metallogenic tracts.

Seafloor environments of the northern Lord Howe Rise, Eastern Australia: Inorganic elements in seabed sediments.

Geoscience Australia marine reconnaissance survey TAN0713 to the Lord Howe Rise offshore eastern Australia was completed as part of the Federal Government's Offshore Energy Security Program between 7 October and 22 November 2007 using the New Zealand Government's research vessel Tangaroa. The survey was designed to sample key, deep-sea environments on the east Australian margin (a relatively poorly-studied shelf region in terms of sedimentology and benthic habitats) to better define the Capel and Faust basins, which are two major sedimentary basins beneath the Lord Howe Rise. Samples recovered on the survey contribute to a better understanding of the geology of the basins and assist with an appraisal of their petroleum potential. They also add to the inventory of baseline data on deep-sea sediments in Australia. The principal scientific objectives of the survey were to: (1) characterise the physical properties of the seabed associated with the Capel and Faust basins and Gifford Guyot; (2) investigate the geological history of the Capel and Faust basins from a geophysical and geological perspective; and (3) characterise the abiotic and biotic relationships on an offshore submerged plateau, a seamount, and locations where fluid escape features were evident. This dataset comprises inorganic element concentrations in seabed sediments.
Some relevant publications which pertain to these datasets include:

Earthquake Resilient Communities: Lessons for Government and Emergency Management

While damaging earthquakes are less frequent in Australia when compared to other weather related events, when they do occur close to communities they can cause major damage and injury.  This community risk to life, property, social fabric and the local economy is significant.  The risk also presents associated challenges for government agencies with a role in emergency response, health care and community recovery both in the short and longer term.  For some communities recovery to pre-event conditions may never be fully realised due to the destruction of heritage value that may be central to local business activity.  Resources for building resilience to earthquakes need to be prioritised against those needed for other hazards.  What are the benefits of earthquake retrofit of high risk buildings to communities and what exemplars of risk management driven from government exist?  What resources exist for a business case to be articulated for limited resources and for motivating investment by property owners to reduce their individual risk?
This document seeks provide useful answer these questions.  It presents information that explains the nature of earthquake hazard in Australia, the risk it presents and vulnerability factors behind it.  It also provides information on the effectiveness of retrofit in reducing the impact of earthquakes, emergency management logistics and recovery needs.  It further provides links to resources that can be used to advance local programs for building community resilience.  The primary focus is the most vulnerable building construction type, unreinforced masonry, but the principles are informative to the address of other high risk building types in communities.
