GSWA Prince Regent Montague Merged Uranium Grid Geodetic

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 radiometric uranium grid has a cell size of 0.00083 degrees (approximately 91m) and shows uranium element concentration of the Prince Regent-Cambden-Montague Sound-Charnley merge, 1994-2012 in units of parts per million (or ppm). The data used to produce this grid was acquired in 1994 by the WA Government, and consisted of 187646 line-kilometres of data at a line spacing between 200m and 800m, and 50m terrain clearance.

Exploring for the Future – Darling-Curnamona-Delamerian project

The Australian Government’s Exploring for the Future program, led by Geoscience Australia, is committed to supporting a strong economy, resilient society and sustainable environment for the benefit of Australians. 
At its heart, the program is about contributing to a sustainable, long-term future for Australia through an improved understanding of the nation’s mineral and energy potential and groundwater resources.  
Since 2016 the program has been working in Northern Australia to understand the potential for buried resources in underexplored areas. The program‘s focus now includes the southern half of the continent, with deep dive projects in potentially resource-rich corridors that stretch across the country. Continental-scale projects are developing a national picture of mineral, energy and groundwater resources.
The Darling-Curnamona-Delamerian (DCD) project - This deep dive project will investigate the mineral potential of the Curnamona Province and Delamerian Orogen in eastern South Australia, western New South Wales, western Victoria and western Tasmania. It will investigate the mineral and groundwater potential of overlying basins including the Murray-Darling Basin and the upper Darling River floodplain.
The DCD project will encourage mineral and groundwater resource exploration and discovery and document new methods for exploring for mineral deposits through the overlying sedimentary basin cover. The project will acquire new data and create new understanding to improve drought resilience in communities and help to provide baseline environmental data for a sustainable future. New resource systems syntheses will stimulate the creation of business and employment opportunities, particularly in the Broken Hill region.
Proposed key activities will include new multi-scale geophysical data acquisition (airborne electromagnetics, magnetotellurics, deep reflection seismic, surface magnetic resonance and downhole geophysics); stratigraphic and groundwater drilling; hydrogeochemical, geochronological and geochemical sampling and analysis; and integration of these new data with historical and state data to deliver geological framework understanding and resource potential assessments. The project will work collaboratively to complement state government and MinEx CRC initiatives in the region

Cloncurry Extension Magnetotelluric Survey – Report and Data

The Cloncurry Extension Magnetotelluric (MT) Survey is located north of the township of Cloncurry, in the Eastern Succession of the Mount Isa Province. The survey expands MT coverage to the north and west of the 2016 Cloncurry MT survey.
The survey was funded out of the Queensland Government’s Strategic Resources Exploration Program, which aims to support discovery of mineral deposits in the Mount Isa Region. 
The survey area is predominantly covered by conductive sediments of the Carpentaria Basin. The cover thickness ranges from zero metres in the extreme south west of the survey, to over 345 meters in the north.
Acquisition started in August 2019 and was completed in October 2020. The acquisition was managed under an collaborative framework agreement between the Geological Survey of Queensland and Geoscience Australia until April 2020, after which the GSQ took over management of the project. Zonge Engineering and Research Organization were responsible for field acquisition.
Data were collected at 2 km station spacing on a regular grid with a target bandwidth of 0.0001 – 1000 s. Instruments were left recording for a minimum of 24 hours unless disturbed by animals. The low signal strength posed a significant impediment for acquiring data to 1000 s, even with the 24 hour deployments. Almost all sites have data to 100 s, with longer period data at numerous sites.

AUSGeoid98 v.1.0 data files:  (sj49-11)

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.

Forbes (SI5507) Depth to bedrock 1:250 000 scale Map - 1st Edition

The image and contours show the depth to slightly weathered bedrock.  In many areas, for instance in the deep palaeovalleys of the Lachlan River and Bland and Goobang Creeks, this is most probably broadly equivalent to the depth of transported sediment cover.  However, from the drill hole logs available, it is generally not possible to distinguish between transported material and highly weathered saprolite. It is therefore difficult in some areas to estimate the thickness of transported versus in situ regolith material. The model of depth to slightly weathered bedrock is derived primarily from the NSW Department of Land and Water Conservation database of almost 2000 water bores drilled on the Forbes 1:250,000 sheet.  These drill holes were supplemented with point and contour data from 
over 300 mineral exploration industry drill holes.  The model was also constrained by the boundaries of outcropping bedrock, and by known and inferred palaeochannel locations interpreted largely from 
seismic and aeromagnetic surveys. The data were gridded using the TOPOGRID module of ESRI's Arc/Info software, which is based on the ANUDEM program developed by M. Hutchinson ("A new procedure for gridding elevation and stream line data with automatic removal of spurious pits", Journal of Hydrology, 106, 211-232, 1989).

Tasmanian Tiers Airborne Magnetic, Radiometric and Digital Elevation Survey, TAS, 2021, (P5003), Block 3, magnetic line data

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 Tasmanian Tiers Magnetic and Radiometric Survey, 2021 survey were acquired in 2021 by the TAS Government, and consisted of 32951 line-kilometres of data at 200m line spacing and 80m terrain clearance.

Large earthquake recurrence in low seismicity regions: accounting for aperiodicity

Characterising earthquake hazard in low seismicity regions is challenging, due to both the inherent lack of data and an incomplete theoretical understanding of the controls on earthquake occurrence away from plate boundaries. In the plate boundary paradigm, elastic rebound theory predicts that cycles of strain accumulation and release will result in regular, or quasiperiodic, recurrence of large earthquakes on individual faults. Analysis of a global compilation of long-term earthquake records shows that this largely holds in plate boundary regions, but begins to break down in intraplate and other low seismicity regions, where more irregular, or aperiodic, earthquake recurrence is observed. 
In this talk the Otago region of southern New Zealand is used as a case study of a low seismicity region with evidence for aperiodic earthquake recurrence. New paleoearthquake and slip rate data are used to extend the record of faulting back more than 100 ka on two faults, the Hyde and Dunstan faults. These data allow the variability of earthquake rates on these faults to be characterised, with novel Bayesian methods developed to forecast the probability of future earthquakes.  Finally, the talk discusses the potential for application of these methods in the Australian context.
