GSSA Fowler ppm Thorium 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 thorium grid has a cell size of 0.00042 degrees (approximately 43m) and shows thorium element concentration of the Fowler Airborne Magnetic Radiometric and DEM Survey, SA, 2017 in units of parts per million (or ppm). The data used to produce this grid was acquired in 2017 by the SA Government, and consisted of 94903 line-kilometres of data at 200m line spacing and 60m terrain clearance.

Yorke Peninsula (Moonta Subdomain) Pre-Neoproterozoic basement geology 1:250000 map

A snapshot of the latest interpretation of the basement geology based primarily on airborne geophysics and drillhole logging.
The Moonta Domain forms the southern part of the Olympic Cu-Au province on the eastern margin of the Gawler Craton, and underlies most of the Yorke Peninsula and Spencer Gulf.  The domain basement comprises metasediments and metavolcanics of the Palaeoproterozoic Wallaroo Group (~1760-1740 Ma) which were deformed and metamorphosed to upper greenschist-amphibolite facies during the Kimban Orogeny (~1720 Ma).  These rocks were further deformed and intruded by granitoids and minor mafic intrusions of the Hiltaba Suite between about 1600 Ma and 1575 Ma.
The Moonta Domain basement is highly prospective for iron oxide-Cu-Au mineralisation associated with the Hiltaba magmatic event.  However outcrop of these basement rocks is limited almost entirely to narrow coastal exposures.  The majority of the prospective basement is concealed by up to 100 metres of Neoproterozoic to Quaternary sediments, and geological mapping of the basement is largely limited to interpretation of geophysics (airborne magnetics, gravity, AEM) and drilling.

Probabilistic earthquake hazard assessment for Fiji

Probabilistic earthquake hazard maps were prepared for the Fiji Islands. Damage has been caused by Fiji earthquakes around 1850, in 1884, 1902, 1919, 1932 (twice), 1953 and 1979. No previous assessment had produced a comprehensive description of the earthquake hazard in Fiji and the present study was initiated in 1990 when the author was attached to the Mineral Resources Department, Fiji. Collection and analysis of data continued at MRD until 1992 and the study was completed at the Australian Geological Survey Organisation in 1993-1997. The aim of the study was to produce probabilistic earthquake hazard maps which can be used in the National Building Code for Fiji, for design of special structures, for planning, for emergency management and for risk management. Few, if any, similar studies have been undertaken in the seismically active Southwest Pacific.

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 RTP 1VD grid (AWAGS) is the first vertical derivative of the TMI RTP grid of the NTGS Mount Peake-Crawford Magnetic, Radiometric and Elevation Survey, NT 2019 survey.
This grid has a cell size of 0.00019 degrees (approximately 20m) , and given in units of nT per metre (nT/m).  The data used to produce the TMI 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. The data has had a variable reduction to the pole applied to centre the magnetic anomaly over the magnetised body. The VRTP processing followed a differential reduction to pole calculation up to 5th order polynomial. Magnetic inclination and declination were derived from the IGRF-11 geomagnetic reference model using a data representative date and elevation representative of the survey. A first vertical derivative was calculated by applying a fast Fourier transform (FFT) process to the TMI RTP grid of the NTGS Mount Peake-Crawford Magnetic, Radiometric and Elevation Survey, NT 2019 survey to produce this grid. This grid was calculated using an algorithm from the INTREPID Geophysics software package. This grid shows the magnetic response of subsurface features with contrasting magnetic susceptibilities. The grid can also be used to locate structural features such as dykes.

Uranium systems processes in the Crocker Well Suite, South Australia

Magmatic-related uranium systems represent an uncommon, yet significant family of uranium mineral systems. Despite the extremely large size of some magmatic-related uranium deposits, the key processes controlling uranium deposition are poorly understood compared to other more common uranium deposit styles. Petrographic, geochemical and fluid inclusion studies have been undertaken at the Crocker Well granite-hosted uranium deposit in South Australia in order to better constrain the key processes in uranium mineralisation there. 
The results of this study allow a genetic model for the Crocker Well deposit to be proposed. Uranium mineralisation is interpreted to be associated with the intrusion of a volatile and sodium-rich pulse of magma, or with the localised release of a highly sodic fluid from the main granitic rocks in the area. Volatile saturation and fluid exsolution partitioned uranium and thorium into a magmatic-hydrothermal fluid phase, and initiated the creation of fractures, veins and breccia zones. These acted as fluid flow pathways for the magmatic fluid. Uranium deposition likely occurred as a result of temperature or pressure decrease.
This genetic model has been translated into a number of mappable criteria which may be used in prospectivity studies for magmatic-related uranium systems. The presence of evidence suggesting the potential to generate a uranium-bearing magmatic fluid, evidence of permeable structures contemporary with igneous activity, and evidence of favourable host rocks are suggested as useful criteria.

Extending groundwater salinity estimation using borehole and AEM data

Salinity of groundwater directly affects its suitability for different uses, from human consumption, agricultural use, to mineral and energy extraction. Traditionally, direct measurements of groundwater salinity at monitoring bores have been used to create salinity maps. However, drilling is expensive and logistically challenging, while leaving us with a small set of salinity measurements over large areas. Airborne electromagnetic (AEM) surveying provides a cost effective solution to this problem. We have developed a scripted geostatistical methodology, which can be repeated on a computer cluster as new AEM data are acquired or boreholes are drilled. We also provide uncertainties on the knowledge gained, allowing remote communities to manage their land and water resources effectively.

Sustainable Management of Coastal Groundwater Resources

The Sustainable Management of Coastal Groundwater Resources (SMCGR) project aims to improve the management of groundwater in coastal dune aquifers, which is used to supply water for coastal communities in the Mid North Coast region.
There is increasing pressure on groundwater resources from expanding urbanisation and tourism in this region, which has made sustainable management of existing groundwater supplies an important issue for coastal communities and councils.
Over extraction from groundwater systems can affect the water available for ecosystems, which may be dependent on shallow groundwater resources. Withdrawal of groundwater resources in excess of the
sustainable yield may also result in fresh water resources being degraded by seawater intrusion or by upcoming from underlying saline water bodies.

Great Artesian Basin - Cadna-owie Hooray Aquifer - Magnesium Concentration

Data used to produce the predicted Magnesium map for the Cadna-owie - Hooray Aquifer in the Hydrogeological Atlas of the Great Artesian Basin (Ransley et.al., 2015).
There are four layers in the Cadna-owie - Hooray Aquifer Magnesium map data
A. Location of hydrochemistry samples (Point data, Shapefile)
B. Predicted Concentration (Filled contours , Shapefile)
C. Predicted Concentration Contours (Contours, Shapefile)
D. Prediction Standard Error (Filled contours , Shapefile)
The predicted values provide a regional based estimate and may be associated with considerable error. It is recommended that the predicted values are read together with the predicted error map, which provides an estimate of the absolute standard error associated with the predicted values at any point within the map.
The predicted standard error map provides an absolute standard error associated with the predicted values at any point within the map. Please note this is not a relative error map and the concentration of a parameter needs to be considered when interpreting the map. Predicted standard error values are low where the concentration is low and there is a high density of samples. Predicted standard errors values can be high where the concentration is high and there is moderate variability between nearby samples or where there is a paucity of data.
Concentrations are Magnesium in mg/L.
Coordinate system is Lambert conformal conic GDA 1994, with central meridian 134 degrees longitude, standard parallels at -18 and -36 degrees latitude.
The Cadna-owie - Hooray Aquifer Magnesium map is one of 14 hydrochemistry maps for the Cadna-owie - Hooray Aquifer and 24 hydrochemistry maps in the Hydrogeological Atlas of the Great Artesian Basin (Ransley et.al., 2014).
