Australian Seismic Site Conditions Map

The Australian Seismic Site Conditions Map (ASSCM) uses information about surficial geology (regolith) as a proxy for the potential behaviour of geological materials under the influence of seismic ground shaking, predominantly in the context of amplification of earthquake energy.
The ASSCM represents a revision and upgrade of the existing National Regolith Site Classification Map of Australia (NRSCM) published in 2007 (McPherson &amp; Hall, 2007). Key improvements to the new product include the integration of new and updated geological data in a more robust spatial reference frame. In addition, a fully documented workflow has been developed, enabling the product to be efficiently updated as required. 
Comparison of different scale input geological data sets demonstrates the power of higher resolution data to provide better discrimination of site conditions - an important factor in determining the reliability of hazard and risk modelling outputs. The implementation of a weathering intensity index captures the reduced strength (and possible minor increase in ground shaking potential) of substrate in bedrock-dominated environments. Accuracy and consistency checking of the ASSCM (and the NRSCM) against geotechnical data from the Newcastle (NSW) and Perth (WA) regions shows good agreement between the ASSCM site condition (site class) mapping and field measurements In both areas the ASSCM out-performs the existing NRSCM.
The ASSCM represents a repeatable and publicly available data set representing Australian seismic site conditions. The generally improved resolution and spatial reliability relative to the existing NRSCM establish the ASSCM as a key input for incorporating seismic site conditions into seismic hazard analysis and modelling in Australia.

AUSGeoid98 v.1.0 data files:  (sh57-06)

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.

Collie, WA, 2011 (P1244), radiometric line data, AWAGS levelled

The radiometric, or gamma-ray spectrometric method, measures the natural variations in the gamma-rays detected near the Earth's surface as the result of the natural radioactive decay of potassium (K), uranium (U) and thorium (Th). 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 Collie, WA, 2011 (P1244), radiometric line data, AWAGS levelled were acquired in 2011 by the WA Government, and consisted of 101882 line-kilometres of data at a line spacing between 200m and 400m, and 50m 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.

Desert varnish coatings and microcolonial fungi on rocks of the Gibson and Great Victoria deserts, Australia

Desert varnish coatings rich in manganese are reported, to the authors knowledge , for the first time on desert rocks from Australia. Varnish was found on chert, dolomite, sandstone, siltstone, and conglomerate rocks in stony pave men Is of the Gibson Desert and the Great Victoria Desert of Western Australia and South Australia. The widespread occurrence of desert pavements in Australia suggests that desert varnish, also, may be widespread. Fungi that form microcolonies have been found on rocks with desert varnish. Manganese was found in higher concentrations inside some of the microcolonies than in the surrounding substrate, suggesting that microcolonial fungi are involved in the formation of desert rock varnish in these areas.

Bathurst , NSW 1961 (P232), 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 Bathurst , NSW 1961 survey were acquired in 1961 by the NSW Government, and consisted of 8800 line-kilometres of data at 1600m line spacing and 150m 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.

Australian Lithospheric Architecture Magnetotelluric Project (AusLAMP) - Queensland Time Series data release (April 2021 - November 2022)

Geoscience Australia’s Exploring for the Future program provides precompetitive information to inform decision-making by government, community and industry on the sustainable development of Australia's mineral, energy and groundwater resources. By gathering, analysing and interpreting new and existing precompetitive geoscience data and knowledge, we are building a national picture of Australia’s geology and resource potential. This leads to a strong economy, resilient society and sustainable environment for the benefit of all Australians. This includes supporting Australia’s transition to net zero emissions, strong, sustainable resources and agriculture sectors, and economic opportunities and social benefits for Australia’s regional and remote communities. The Exploring for the Future program, which commenced in 2016, is an eight year, $225m investment by the Australian Government.

As part of Exploring for the Future (EFTF) program with contributions from the Geological Survey of Queensland, long-period magnetotelluric (MT) data for the Australian Lithospheric Architecture Magnetotelluric Project (AusLAMP) were collected using Geoscience Australia's LEMI-424 instruments on a half-degree grid across northern and western Queensland from April 2021 to November 2022. This survey aims to map the electrical resistivity structures in the region. The processed data and 3D resistivity model have been released (https://dx.doi.org/10.26186/148633).&nbsp;

This data release includes acquired time series data and metadata for each site. The script used to package the time series data is provided. The time series data are available in their original format (.txt), as recorded by the data logger, as well as in MTH5 hierarchical format. The open-source MTH5 Python package (https://github.com/kujaku11/mth5) was used to convert the recorded data to MTH5 format.

We acknowledge the traditional landowners, private landholders and national park authorities within the survey region, without whose cooperation these data could not have been collected.
