Hyden North, WA, 1997 (P1078), 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 Hyden North, WA, 1997 survey were acquired in 1997 by the WA Government, and consisted of 5209 line-kilometres of data at 400m line spacing and 40m 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.

Resistivity structures derived from AusLAMP magnetotellurics data in Queensland

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 Queensland from April 2021 to November 2022. This survey aims to map the electrical resistivity structures in the region. These results provide additional information about the lithospheric architecture and geodynamic processes, as well as valuable precompetitive data for resource exploration in this region.
This data release package includes processed MT data, a preferred 3D resistivity model projected to GDA94 MGA Zone 54 and associated information for this project.
The processed MT data were stored in EDI format, which is the industry standard format defined by the Society of Exploration Geophysicists. The preferred 3D resistivity model was derived from previous EFTF AusLAMP data acquired from 2016-2019 and recently acquired AusLAMP data in Queensland. The model is in SGrid format and geo-referenced TIFF format.

Geochemical data analysis system (GDA): reference manual

GDA (Geochemic al Data Analysis) is a comprehensive IBM PC-based geochemical data
processing system. It is designed to use whole-rock geochemical data retrieved from the
ORACLE database, but can be adapted for other databases, or data can be entered into
files from the keyboard. The programs are written in FORTRAN 77 (microsoft compiler)
and use the MicroGlyph Systems SciPlot graphics package for plotting. The system
includes facilities for generating plots (histograms, XY plots, triangular plots,
spidergrams, box-whisker plots, etc.), calculating statistical functions (e.g., mean,
standard deviation, regression lines, correlation coefficients and cluster analysis) and
CIPW norms, printing tables, and carrying out petrogenetic modelling calculations. Plots
can be displayed on a PC screen for inspection and editing before being output to a plotter
or other device. Other programs allow samples to be assigned to groups for plotting
purposes, and allow editing and merging of datafiles.

The effects of storm clustering on storm demand and dune recession at Old Bar, NSW.

Old Bar Beach on the NSW mid-coast is an erosion hotspot with chronic dune recession rates exceeding 0.5 m/yr combined with extreme storm demand events upwards of 200 m3/m. With resultant property loss, Old Bar is a focus for active shoreline management by Midcoast Council. Here we demonstrate a new approach to distinguish the erosional effects of individual storms versus clusters of storms. We modelled the observed sediment transport inside the Old Bar coastal compartment and used probabilistic modelling to quantify both shoreline recession and storm demand. The hybrid cross shore (equilibrium type) longshore morphodynamic Shoreline Evolution (EVO) model developed by WBM BMT was setup for the Old Bar coastal compartment. A suite of probabilistic synthetic time series of waves and tides were used to force the model allowing us to make robust statistical assessments of the modelled erosion. In the subsequent analysis, erosion caused by individual storms are merged into “clustered” events if accretionary beach recovery between storms was less than 50 percent. 
Modelling results were in line with previous studies indicating continued recessions of 0.5m/yr and 50 year storm demands that exceed 200m3/m. Preliminary analysis of storm clustering suggests that recession and storm demand for clustered events are greater than for individual storms. These findings suggest that traditional “design storm” methods based solely on the most severe individual storm event will underestimate recession and storm demand return periods. Results will aid ongoing management and planning supported by NSW Office of Environment and Heritage and Midcoast Council to better understand the nature of the coastal hazards that continue to place some beachfront properties at risk.   
The Old Bar study was undertaken for the Bushfire and Natural Hazards CRC project ‘Resilience to clustered disaster events on the coast - storm surge’.]

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. The terrestrial dose rate grid is derived as a linear combination of the filtered K, U and Th grids. A low pass filter is applied to this grid to generate the filtered terrestrial dose rate grid.
This GSQ Isa Georgetown Block A Qld dose rate grid geodetic has a cell size of 0.00042 degrees (approximately 45m) and shows the terrestrial dose rate of the Isa-Georgetown Block A,QLD, 2000, Prospectivity Plus Initiative. The data used to produce this grid was acquired in 2000 by the QLD Government, and consisted of 34868 line-kilometres of data at a line spacing between 200m and 400m, and 80m terrain clearance.

Combined seismic-gravity interpretation over the Donnybrook Anticline, central Queensland

Accurate modelling, using seismic and gravity data, has shown that the Donnybrook Gravity High in central Queensland is the result of a complex situation involving three discordant basins. The most significant is an old basin buried deep beneath the Drummond Basin and apparently deposited in a valley carved out of a thick sequence of Silver Hills Volcanics and related acid volcanics. The Drummond Basin wedges out westwards under the Galilee Basin and is bounded to the east by the same acid volcanics that subcrop near the Anakie Metamorphics. The illusion that the Donnybrook Gravity High is associated with the Donnybrook Anticline is the result of an intrabasement granite which introduces a large negative component, cancelling the western flank of a much broader gravity high. After the cancellation, the granite is represented by a low of only 30 ~m.s-2 The already complex situation is further complicated by a topographic feature that introduces ambiguity in the most crucial area of the interpretation . This factor demonstrates the need to combine density profiling with forward modelling.

Probabilistic Inversion of Audio Magnetotelluric Data in the East Tennant region, Northern Territory, Australia

As part of Geoscience Australia’s Exploring for the Future Program, Broadband and Audio Magnetotelluric (MT) data were acquired at 131 stations in the East Tennant region, Northern Territory, in 2019. This survey aimed to characterise major crustal structures, to map cover thickness to assist in stratigraphic drill targeting, and to help understand mineral potential in the region. The data package was released in December 2019 (http://dx.doi.org/10.26186/5df80d8615367) and the 3D resistivity model was released in March 2020 (https://pid.geoscience.gov.au/dataset/ga/135011).
We applied a probabilistic approach to inverting high-frequency MT data for cover thickness estimation using the 1D Rj-McMCMT code, newly developed in Geoscience Australia. The inversion employs multiple Markov chains in parallel to generate an ensemble of millions of resistivity models that adequately fit the data given the assigned noise levels. The algorithm uses trans-dimensional Markov chain Monte Carlo techniques to solve for a probabilistic resistivity-depth model. Once the ensemble of models is generated, its statistics are analysed to assess the posterior probability distribution of the resistivity at any particular depth, as well as the number of layers and the depths of the interfaces. This stochastic approach gives a thorough exploration of the model space and a more robust estimation of uncertainty than deterministic methods allow.
This release package includes the results of probabilistic inversion of Audio Magnetotelluric data at the 131 stations. They can be used to estimate cover thickness for drill site planning, and to map the base of geological basins in the region.
Model data files are large, but can be made available on request to clientservices@ga.gov.au.

The conductivity structure of the Georgina-Arunta region from magnetotelluric data

We present an updated resistivity model from inversion of the 09GA-GA1 deep magnetotelluric survey, also known as the Georgina-Arunta survey. The data were originally collected in 2009 under Geoscience Australia’s Onshore Energy Security Program, together with deep seismic reflection data along the same line. The magnetotelluric data comprise broadband and long-period data. The broadband data were originally processed to a bandwidth of 0.04 s to 100 s, but have been reprocessed yielding an extended bandwidth of 0.04 s to 1000 s, which improves the resolution of deeper (&gt;20 km depth) structures. Inversions have been carried out using the ModEM 3D inversion code given that the data indicate the presence of 3D geoelectric structure. The updated resistivity model reveals that the Casey Inlier and Irindina Province are associated with high resistivities (&gt;2000 Dm). In contrast, the Aileron Province, which underlies and surrounds the Irindina Province, is predominantly conductive (resistivities &lt;50 Dm). The Georgina Basin is associated with low resistivities, as would be expected for a sedimentary basin, while the Amadeus Basin is associated with low resistivities in the southern part of the line (where it overlies the Casey Inlier), and higher resistivities further north.
