Silurian and Late Carboniferous conodonts from the Charles Louis Range and central Birds Head, Irian Jaya, Indonesia

Conodonts have been recovered in samples from two stratigraphic units in Irian Jaya: the Modio Dolomite in the Charles Louis Range, and probably the Aimau Formation in the central Birds Head.  The Modio Dolomite fauna includes Panderodus cf. P. simplex (Branson and Mehl, 1933), and probably has a Silurian age. Two float samples considered to have been derived from the Aimau Formation yielded a fauna comprising Neognalhodus cf. N. bassleri (Harris and Hollingsworth , 1933) and Hindeodus minutus (Ellison, 1941), which indicate a Late Carboniferous age.

Satellite navigation and the Southern Positioning Augmentation Network (SouthPAN)

Satellite navigation is an important capability in our modern lives—we use it to find the nearest petrol station, order food at home, and track an arriving package. Accurate satellite-enabled positioning and timing technology is also becoming vital in many industrial sectors of the economy, including transport, agriculture, resources, and utilities. On behalf of the Australian government and in partnership with New Zealand, Geoscience Australia is improving satellite navigation capability for everyone with the Southern Positioning Augmentation Network, or SouthPAN.  SouthPAN is a Satellite-Based Augmentation System that will use new spacecraft, ground sensors, and other infrastructure to broadcast corrections that complement existing Global Navigation Satellite Systems—like GPS, for example. SouthPAN services will commence in 2022 and be progressively improved in the coming years, ultimately being used in their most critical application: by aircraft to land at airports.

Accessible groundwater information. A methodology for the GeoInsight pilot

GeoInsight was an 18-month pilot project developed in the latter part of Geoscience Australia’s Exploring for the Future Program (2016–2024). The aim of this pilot was to develop a new approach to communicating geological information to non-technical audiences, that is, non-geoscience professionals. The pilot was developed using a human-centred design approach in which user needs were forefront considerations. Interviews and testing found that users wanted a simple and fast, plain-language experience which provided basic information and provided pathways for further research. GeoInsight’s vision is to be an accessible experience that curates information and data from across the Geoscience Australia digital ecosystem, helping users make decisions and refine their research approach, quickly and confidently. 

In the first iteration of GeoInsight, selected products for energy, minerals, water, and complementary information from Geoscience Australia’s Data Discovery Portal and Data and Publications Catalogue were examined to (1) gauge the relevance of the information they contain for non-geoscientists and, (2) determine how best to deliver this information for effective use by non-technical audiences. 

This Record documents the technical details of the methods used for summarising groundwater information for GeoInsight, including groundwater reliance, depth, salinity, and uses. This Record will be updated, including a change log, when the scope of information or methods for generating the data change.

AUSGeoid98 v.1.0 data files: Connemara (sg54-03)

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.

Geoscience Australia's contribution to Australian mineral exploration

Since 1946 Geoscience Australia has been providing pre-competitive (non-rivalous) data and information to the minerals and petroleum exploration industries which has played an important part in resource discovery, including the Olympic Dam and Lihir deposits, and the Browse Basin hydrocarbon field. The modest investment in precompetitive data has resulted in economic benefits to Australia orders of magnitude greater than cost.
Australia is currently seen by industry as a mature exploration destination as most of the exposed regions have been extensively explored. However, Australia has large areas of basement covered by younger sedimentary rocks and regolith, which is both an opportunity and a challenge. To address this challenge, Geoscience Australia has begun a data collection program aimed at determining what data are required to explore undercover and providing that data in northern Australia. Data acquisition will include a range of non-traditional geophysical and geochemical methods and the data will be used to assess mineral potential on regional and national scales. In the future, Geoscience will extend this data coverage into southern Australia and develop methods of assessing the viability of resource development in remote Australia.

NT Road Surveys 1987-1997 Musgrave Block (P199381), gravity point data

Gravity data measures small changes in gravity due to changes in the density of rocks beneath the Earth's surface. The data collected 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 NT Road Surveys 1987-1997 Musgrave Block (P199381) contains a total of 236 point data values acquired at a spacing between 200 and 1000 metres. The data is located in NT and were acquired in 1993, under project No. 199381 for Northern Territory of Australia (Northern Territory Geological Survey).

Proposed Australian Building Stock Categorisation for Bushfire and Natural Hazards CRC Earthquake Project

This paper presents the initial building vulnerability schema proposed for the Bushfire and Natural Hazards Collaborative Research Centre (BNHCRC) project entitled 'Cost-Effective Mitigation Strategy Development for Building Related Earthquake Risk'. The development of a building schema which categorises Australian building stock into distinctive vulnerability classes is an integral part of the risk and impact assessment process. In undertaking this categorisation a review was undertaken of existing earthquake vulnerability schema found in the literature alongside a schema developed by an expert group for Australia. The schemas found in the literature were HAZUS, the United Nations' Global Assessment Report on Risk, RiskScape, the Global Earthquake Model, USGS PAGER, and the European Macroseismic Scale-98. Also included was the Australian specific schema developed based on the recommendations made at a workshop in Melbourne in February 2001 (Stehle et al., 2001). Key building parameters from each of these were considered along with the building types found in the countries or regions where these schemas were developed. The proposed schema categorises buildings by the building attributes Building Usage, Primary Lateral Load Resisting System, Height Range, Proximity to Coast, Wall Type, Wall Material, Roof Material, and Age. The draft schema has been developed in recognition of the current and projected ability to define national building exposure and of the parallel BNHCRC mitigation projects examining vulnerability to wind and riverine flooding. While vulnerability schemas are very hazard specific, alignment has been sought with the other hazards where possible. The draft schema is considered to be a preliminary version, and is expected to evolve during the project as it develops new knowledge on vulnerability and mitigation options for key high risk Australian building types.

An isotopic study of granitoids in the Litchfield Block, Northern Territory

The Litchfield Block contains a variety of granitoids, gneissic rocks, and migmatites that are intrusive into metasediments of probable Early Proterozoic age at the western margin of the Pine Creek Inlier. Isotopic data, which include U-Pb measurements on cogenetic zircon and xenotime and Rb-Sr total-rock measurements on the least metamorphosed granodiorites, show that these rocks crystallised from mantle-derived melts between 1840 Ma and 1850 Ma ago. Radiogenic Pb was lost from zircon in the early Palaeozoic (about 435 Ma), but xenotime remained a closed system until recent time. Many granitoids in the Litchfield Block have a gneissic fabric imposed during greenschist to amphibolite-grade regional metamorphism. This disturbance allowed partial isotopic re-equilibration of Rb-Sr total-rock systems, at about 1770 Â± 16 Ma. As this igneous and metamorphic evolution is mirrored in other parts of the Pine Creek Inlier, the Halls Creek Inlier, and many other orogenic belts in northern Australia, its recognition and isotopic definition in the Litchfield Block further emphasise the magnitude and chronological integrity of this early Proterozoic tectonic event.

Cooper Basin Source Rock Geochemistry: Regional Hydrocarbon Prospectivity of the Cooper Basin: Part 2

The Cooper Basin is a Pennsylvanian - Middle Triassic intracratonic basin in northeastern South Australia and southwestern Queensland. In conjunction with the overlying Eromanga Basin, the basin is Australia's largest onshore producer of gas and oil. Exploration activity in the region has recently expanded with explorers pursuing a range of newly identified unconventional hydrocarbon plays. These include extensive tight gas accumulations in the Gidgealpa Group, deep dry coal seam gas associated with the Patchawarra and Toolachee formations, the less extensive shale gas plays in the Roseneath and Murteree shales and mixed lithotype hybrid plays (Goldstein et al., 2012; Menpes et al., 2013; Greenstreet, 2015).
The Australian Petroleum Source Rocks Mapping project is a new study to improve our understanding of the petroleum resource potential of Australia's sedimentary basins. The source rocks of the Cooper Basin are the first to be assessed for this project, as a detailed understanding of the petroleum generation potential of these is critical for determining both the conventional and unconventional hydrocarbon prospectivity of the basin. This report reviews the Cooper Basin source rock geochemistry and maturity based on a compilation of updated and quality controlled publically available total organic carbon (TOC), Rock-Eval pyrolysis and vitrinite reflectance data. 
This is the first study of its kind to be undertaken for the Cooper Basin as a whole and builds on the previous work of Boreham &amp; Hill (1998) in South Australia. The resulting maps and statistics quantifying the spatial distribution, quantity and quality of the Cooper Basin's source rocks provide important insights into the hydrocarbon prospectivity of the basin.

Mount Peake-Crawford - TMI grid (AWAGS)

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 Mount Peake-Crawford - TMI grid (AWAGS) has a cell size of 0.00019 degrees (approximately 20m). The units are in nanoTesla (or nT). The data used to produce this grid was acquired in 2019 by the NT Government, and consisted of 136990 line-kilometres of data at 200m line spacing and 60m terrain clearance. 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.
