NSW DMR, Discovery 2000 Area K, Peel - South West (Maules Creek), NSW, 1998 (P740), elevation line data

The Digital Elevation Model represents ground surface topography between points of known elevation. The elevation data was calculated using the altimeters and Global Positioning System (GPS) sensor used for the benefit of airborne magnetic and radiometric data on the same survey. The elevation is the height relative to the Australian Height Datum GDA94 (AUSGEOID09). The processed elevation 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 K, Peel (Inverell,Manilla), NSW, 1998 survey were acquired in 1998 by the NSW Government, and consisted of 61165 line-kilometres of data at 250m line spacing and 60m terrain clearance.

Australia's Seabed Map 2023

The map and underlying digital dataset provide national and regional-scale context for a wider variety of applications, including offshore industries, area-based environmental management, scientific research and public education.  
Australia’s Seabed Map is based on the revised AusBathyTopo 250m (Australia) 2023 grid (Beaman, 2023), the most comprehensive, continental-scale compilation of bathymetry data in the Australian region.  
The map extends across a vast area from 92°E to 172° E and 8°S to 60° S. This includes areas adjacent to the Australian continent and Tasmania, and surrounding Macquarie Island and the Australian Territories of Norfolk Island, Christmas Island, and Cocos (Keeling) Islands. Australia's marine jurisdiction offshore from the territory of Heard and McDonald Islands and the Australian Antarctic Territory are not included. 
The new map provides a complete three-dimensional picture of the seafloor and is a significant improvement since it was last revised in 2009. In particular, the map incorporates new innovations such as the use of earth observation data (satellite based) produced by Digital Earth Australia to improve coastline definition and present a seamless transition between land and sea. The data is compiled from 1582 individual surveys using multibeam echosounders, single-beam echosounders, LiDAR, or 3D seismic first returns, as well as higher-resolution regional compilations, and other source data including Electronic Navigation Charts and satellite derived bathymetry. The new map represents decades of data collection, analysis, investment and collaboration from Australia’s seabed mapping community.  
The 250 m resolution is only supported where direct bathymetric observations are sufficiently dense (e.g. where swath bathymetry data or digitised chart data exist). In many regions, this 250 m grid size is far in excess of the optimal grid size for some of the input data used. 
The AusBathyTopo250m grid and higher-resolution regional datasets are available on the AusSeabed Marine Data Portal as the AusBathyTopo Series.  
This map is not suitable for use as an aid to navigation, or to replace any products produced by the Australian Hydrographic Office.

Australian Critical Minerals Map 2020

This map shows the locations and status, as at 30 June 2020, of Australian operating mines, mines under development, mines on care and maintenance and resource deposits associated with critical minerals. 
Developing mines are deposits where the project has a positive feasibility study, development has commenced or all approvals have been received. Mines under care and maintenance and resource deposits are based on known resource estimations and may produce critical minerals in the future. The critical mineral deposits on this map may not be comprehensive for all commodities.
For the purposes of this map, critical minerals are defined as minerals and elements (solid and gaseous) that are vital for modern technology and whose supply may be at risk of disruption. The Australian critical minerals list comprises antimony, beryllium, bismuth, chromium, cobalt, gallium, germanium, graphite, hafnium, helium, indium, lithium, magnesium, niobium, platinum group elements, rare earth elements, rhenium, scandium, tantalum, titanium, tungsten, vanadium and zirconium. These commodities are coloured by mineral groupings on the map.

AUSGeoid98 v.1.0 data files:  (sk56-10)

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.

New geomechanical and petrophysical data from NDI Carrara 1. Implications for Carrara Sub-basin unconventional prospectivity

NDI Carrara 1 is the first stratigraphic test of the Carrara Sub-basin, a newly discovered depocentre in the South Nicholson region that was identified on newly acquired seismic surveys undertaken as part of the Exploring for the Future program. NDI Carrara 1 intersected a thick sequence of Proterozoic aged siliciclastic and carbonate rocks, which host several intervals of interest to hydrocarbon explorers due to affinities with the known Proterozoic shale gas plays of the Beetaloo Sub-basin and the Lawn Hill Platform. These include two organic-rich black shale sequences and a thick sequence of interbedded black shales and silty-sandstones where numerous hydrocarbon shows are demonstrated. An extensive suite of wireline logs was acquired from total depth to the near surface, and continuous core was recovered through the Proterozoic interval. Geoscience Australia and partners are undertaking an extensive program of analytical work to understand the depositional, structural, and diagenetic history of the sediments intersected by NDI Carrara 1, alongside their resource potential.
This study characterises petrophysical and geomechanical properties of the Proterozoic interval of NDI Carrara 1 through interpretation of wireline logging data and integration of some of this interpretation with results of geochemical analyses. High interpreted TOC content and a high calculated net shale ratio, alongside high estimated hydrocarbon saturations suggest a high potential for unconventional gas resources in the Proterozoic shale intervals of the Carrara Sub-basin; an assessment supported by gas peaks, particularly methane, measured in mud-logging gas profiles during drilling. Shale brittleness indices and interpreted present-day stresses highlight areas that are likely to be favourable for unconventional gas techniques and which may form attractive shale gas plays. Interpretation of the L210 and L212 seismic surveys suggests that the intersected sequences are laterally extensive and continuous throughout the Carrara Sub-basin, potentially forming a significant new hydrocarbon province and continuing the Proterozoic shale play fairway across the Northern Territory and northwest Queensland.

Significance of pseudotachylite vein systems, Giles basic/uItrabasic complex, Tomkinson Ranges, western Musgrave Block, central Australia

Pseudotachylite vein-breccia networks and pseudotachylites intrafoliated with mylonites occur pervasively in the Tomkinson Ranges, western Musgrave Block, central Australia, about 50 km south and constituting part of the hanging wall of the Woodroffe thrust. The pseudotachylites are almost exclusively confined to gabbro, anorthosite and dolerite, and are rarely seen in basic granulites, felsic granulites and granitic gneiss.  Pseudotachylite is ubiquitous in steeply tilted, deformed and mylonite-intersected sectors of the Giles Complex (Hinckley Range, Kalka, Michael Hills) but was not detected in the mildly tilted and little deformed western sectors of the Giles Complex (Blackstone Range, Cavenagh Range, Jameson Range), suggesting that fusion events concentrated in deformed relatively deep crustal levels.  Two principal modes of occurrence of pseudotachylite are recognised : 1, vein-breccia networks superimposed on older lithological contacts and associated with brittle fracture systems; 2, penetrative pseudotachylite laminae interleaved with mylonite along shear zones.  It is inferred that friction fusion events triggered by seismic faulting have affected intermediate crustal levels where mylonite shears separate brittle fracture domains.  Contemporaneous development of pseudotachylite in each domain may be suggested by the lack of observed intersecting relationships between the two types of pseudotachylite vein systems.  Alternatively, the mylonite-related pseudotachylites may have formed in quasi-plastic deep crustal zones.  Comparisons between the chemistry of pseudotachylites and bulk host rock composition suggest a limited degree of selective fusion, increasing the silica levels and lowering the Mgvalues and Cr levels in the melt.  Alternatively, these variations may have been brought about by fluid phase activity.  Evidence for a high temperature melt origin of the pseudotachylite includes finer-grained margins, resorbed microclasts, micron-scale subhedral crystal texture of the pseudotachylite and distinct chemistry of microphenocrysts compared with host rock mineral composition. Laser-Raman spectroscopy has shown that the material is mostly crystalline but also suggests the occurrence of minor glass components in the pseudotachylite. High-Al and high-K pyroxenes from the pseudotachylite suggest seismic overpressures of the order of 30 kb, or metastable disequilibrium quench crystallisation of the pseudotachylite melt.

New insights into the development of the South Nicholson Basin, northern Australia from SHRIMP U–Pb detrital zircon and authigenic xenotime

The Mesoproterozoic South Nicholson Basin (SNB) in northern Australia extends across an area approximately the size of Tasmania. It is flanked by the resource rich Mt Isa Orogen and McArthur Basin.  Limited outcrop and a dearth of drilling has hampered understanding of the evolution of the Basin, its relationship to other tectonic elements in northern Australia and its resource potential. The lack of any identified interbedded volcanic rocks within the studied sections has led us to concentrate on an extensive SHRIMP U-Pb detrital zircon geochronology program that so far exceeds 40 samples. In addition, we have undertaken SHRIMP U-Pb geochronology of authigenic xenotime.

Detrital zircon U–Pb maximum depositional ages (MDA) for the South Nicholson Group (SNG) are up to 100 My younger than previously reported [1]. The new MDA for the Constance Sandstone is ~1470 Ma and is the youngest so far recorded in the SNB. Additionally, it accords with an MDA for the underlying Crow Formation of ~1483 Ma. SHRIMP U–Pb xenotime analyses of authigenic overgrowths on detrital zircons from the Constance Sandstone gave an age of ~1266 Ma. This new data brackets the deposition of the SNG to between 1470 Ma and ~1266 Ma and provides the first evidence that the SNG is broadly contemporaneous with the 1500–1320 Ma Roper Group of the McArthur Basin. Using Multidimensional Scaling of the detrital age distributions has also added an extra dimension to our evolving understanding of the development of the SNB.

Earthquake Mitigation of WA Regional Towns York Case Study: Final Report

This document reports on a Bushfire and Natural Hazards Collaborative Research Centre (BNHCRC) utilisation project that has sought to develop information on the most effective means to address York’s high risk buildings.  It has also sought to develop a better understanding of the logistics that would be faced by the state emergency services and the local shire council in a rare but credible earthquake.  The utilisation project is entitled “Earthquake Mitigation of WA Regional Towns: York Case Study”, and sits under the over-arching BNHCRC Project A9 “Cost-effective Mitigation Strategy Development for Building Related Earthquake Risk”.  The work commenced in January 2018 and was undertaken over a two year period.  It involved the University of Adelaide and Geoscience Australia as the CRC research partners, and DFES and the Shire of York as the end users.  The WA DPLH has also been a participant, though not a formal BNHCRC end user.  The project had the following key components:-
•   Develop a building, business and demographic exposure database for York with the attributes collected tailored for modelling earthquake impact and for quantifying avoided consequences in economic terms.
•   Examine the benefits and costs of retrofitting old URM buildings to improve the resilience of them to earthquake.  This is to range in scale from individual households and businesses up to the community as a whole.
•   Prepare earthquake impact scenarios suitable for emergency management planning by DFES and the Shire of York.
