Investigation of a Lower-plate Continental Margin: A Proposal for Drilling in the Great Australian Bight Region by the Ocean Drilling Program

The southern margin of Australia, formed by the separation of Australia and Antarctica in theCretaceous, has long been considered an example of a classic, non-volcanic, passive, rifted margin. In recent times it has been cited as an excellent example of a 'lower plate' margin inthe terminology of detachment models of passive margin formation. As the margin has been relatively sediment-starved since breakup, and particularly in the Tertiary, it represents anexcellent opportunity to test detachment models via reflection seismic data and drilling.
In this document, we propose that a total of seven holes be drilled by the Ocean DrillingProgram in the central Great Australian Bight (GAB). Five of these holes are located close tothe previously interpreted continent-ocean boundary (COB), which high-quality seismic datasuggest may actually be a metamorphic core complex. The holes have the following basic aims:
1.Test the applicability of detachment tectonics to passive margin formation by drillingthrough a master detachment to extended lower continental crust;
2.Sample acoustic basement at several sites to characterise the tectonic and magmaticprocesses that have been influential at high rates of continental extension and/or duringearly and slow oceanic spreading.
In the event that the interpretation of a metamorphic core complex proves to be incorrect and oceanic crust is encountered, then two additional holes are proposed to:
1.Date the oldest sediments above oceanic crust in the South Australian Abyssal Plain, andhence constrain the currently ill-defined age of onset of spreading between Australia andAntarctica and refme the breakup history of eastern Gondwanaland.
2.Date and characterise the extensional listric faulting that is prominent in possible oceaniccrust on the South Australian Abyssal Plain. 
As the data on which these sites are proposed is sparse and, in some cases, old, the AustralianGeological Survey Organisation (AGSO) proposes to carry out a deep-seismic program in thecentral GAB that will allow a refmal interpretation and consequent up-grading or modificationof the proposed sites in 1995/96.

Development of tsunami hazard maps for the Mentawai Islands, Indonesia, using heterogeneous slip models

Heterogeneous distribution of slip during megathrust earthquakes has been shown to significantly affect the spatial distribution of tsunami height in both numerical studies and field observations. This means that tsunami hazard maps generated using uniform slip distributions in their tsunami source models may underestimate tsunami inundation in some locations compared with real events of the same magnitude in the same location. In order to more completely define areas that may be inundated during a tsunami it is important to consider how different possible distributions of slip will impact different parts of the coastline. We generate tsunami inundation maps for the Mentawai Islands, West Sumatra, Indonesia, from a composite suite of possible source models that are consistent with current knowledge of the source region.
First, a suite of earthquake source models with randomly distributed slip along the Mentawai Segment of the Sunda Subduction Zone is generated using a k-2 rupture model. From this suite we select source models that generate vertical deformation consistent with that observed in coral palaeogeodetic records of previous ruptures of the Mentawai Segment in 1797 and 1833, minus deformation observed in the 2007 Bengkulu earthquake sequence. Tsunami inundation is then modelled using high resolution elevation data for selected source models and the results compiled to generate a maximum tsunami inundation zone. This method allows us to constrain the slip distribution beneath the Mentawai Islands, where coral palaeogeodetic data is available, while allowing for greater variation in the slip distribution away from the islands, in particular near the trench where large slip events can generate very large tsunami. This method also allows us to consider high slip events on deeper portions of the megathrust between the Mentawai Islands and the Sumatran Mainland, which give greater tsunami inundation on the eastern part of the Mentawai Islands and the west coast of Sumatra compared with near-trench event. By accounting for uncertainty in slip distribution, the resulting hazard maps give a more complete picture of the areas that may be inundated compared with hazard maps derived from a single 'worst case' source model. These maps allow for more robust tsunami evacuation plans to be developed to support immediate community evacuation in response to strong or long-lasting earthquake ground shaking.

National-scale critical mineral assessments to support accelerating discovery in Australia

The production of critical and strategic minerals will be key for the transition to net zero and will require increased rates of discovery to support the provision of feedstock into the earliest stages of the supply chain. Given the importance of critical and strategic minerals to the Australian national economy, a series of national-scale mineral potential assessments have been undertaken as part of the Exploring for the Future program at Geoscience Australia to support exploration, search space reduction, and discovery. These assessments focus on delineating prospective belts or districts that indicate the presence of favourable mineral system processes, derived from both new and legacy geological, geophysical, and geochemical data sets acquired as part of precompetitive geoscience programs at the national scale. Assessments have been undertaken for sediment-hosted base metal, carbonatite-related rare earth element, and iron oxide-copper-gold mineral systems in Australia. Additional national-scale assessments are currently underway for high-purity silica and other rare earth element mineral systems as part of Geoscience Australia’s involvement in the Australian Critical Minerals Research and Development Hub. Such assessments are underpinned by high-quality precompetitive geoscience data and mineral systems understanding, which often comes from compilation of global-scale data sets, such as the Critical Minerals in Ores database, and understanding of the formation of mineral systems in a global context, which are then integrated using appropriate methodologies, including a newly developed hybrid data- and knowledge-driven approach for mineral potential mapping, to generate robust mineral potential maps that delineate the most geologically prospective areas. This presentation will highlight Geoscience Australia’s work on delivering national-scale mineral potential assessments to support an improved understanding of Australia’s critical minerals inventory.

Yowalga Sub-Basin, WA, 1995-1996 (P916), 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 Yowalga Sub-Basin, WA, 1995-1996 survey were acquired in 1995 by the WA Government, and consisted of 87401 line-kilometres of data at 500m line spacing and 80m 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.

AUSGeoid98 v.1.0 data files:  (sh49-02)

AUSGeoid98 data files contain a 2 minute grid of AUSGeoid98 data covering the Australian region, which you can use to interpolate geoid-ellipsoid separations for the positions required.You can use your own interpolation software, or you can use Geoscience Australia's Windows Interpolation software (Winter). The data files are text files in a standard format that cover the same area as standard topographic map areas. Files covering both 1:250,000 (approximately 100 x 150 km) and 1:1,000,000 (approximately 400 x 600 km) map areas are available. There is a 4 minute overlap on all sides of each area. Data format: AUSGeoid98 data files have a header record at the start of each file, to distinguish them from the superseded AUSGeoid93 data files. AUSGeoid98 data files show the geoid-ellipsoid separation to 3 decimal places, while the superseded AUSGeoid93 data files showed only 2 decimal places. AUSGeoid98 deflections of the vertical were computed from the geoid-ellipsoid separation surface, while the AUSGeoid93 deflections of the vertical were computed from OSU91A.

3D Geological Models of Australia - January 2014

Geoscience Australia (GA) has created a unique collection of 3D structural and geological models and model inputs for Australia and its near shore regions. Currently the collection contains a variety of 3D volumetric models and surfaces that were produced for specific projects at regional to continental scale. The approximately 40 regional scale models in the collection cover roughly 1/3 of the Australian continent. The models capture 3D stratigraphy and architecture, including the depth to bedrock and the locations of different major rock units, faults and geological structures. The geologic models represent the integration of geophysical surveys, seismic surveys, borehole data, field geology, and geochemical data, the majority of which will now be available through this and other RDSI collections.  In their current form, the 3D models provide a valuable input to simulations of geological processes. However, the plan over time is to use the HPC capability at NCI and the large storage volumes available to dynamically integrate the various models and geological, geochemical and geophysical derivative products to then create a unified 3D model for the entire continent. Separately and then cumulatively, these models will provide an important new basis for describing and understanding Australia's geologic evolution and resource wealth.
Currently there are no international open standards for the development and storage of 3D geological models, which is why they are difficult to integrate or stitch into nationally integrated data sets. The lack of consistency of the models means that each has to be transformed into formats compatible with existing HP modelling and simulation software. It is hoped that through exposing these 3D geological models into a HP collaborative environment that this will foster and accelerate the development of international standards and tools necessary for the assimilation of 3D geological models into a variety of HP programs.

Analysis of conodont apparatus organisation and the genus lumudontus (Conodonta), a coniform-pectiniform apparatus structure from the Early Ordovician

A classification of conodont apparatus structure is set out, based on the type of element (coniform, ramiform or pectiniform) found in the discernens and contundens groups of elements. Of a possible nine organisational structural configurations, only four (coniform-coniform, coniform-pectiniform, ramiform-ramiform and ramiform-pectiniform) have been reported in the literature. The coniform- ramiform configuration is possible but has not yet been recognised; all other apparatus configurations are regarded as biologically improbable. The genus Jumudontus Cooper from the Early Ordovician (Arenig), represented by J. gananda Cooper, is shown to have a septimembrate coniform-pectiniform apparatus configuration. Jumudontus brevis sp. nov. is described, based on a partial apparatus reconstruction, using specimens from the Emanuel Formation of the Canning Basin, Western Australia.
