Uranium deposit types: a systems perspective

Uranium deposits are generally classified into types based on host rock, orebody morphology or structural setting.  Widely used schemes contain 14 or more deposit types and numerous sub-types. However, groups of deposit types were formed by similar geological and geochemical processes and likely represent 'variations on a theme'.  An alternative scheme is presented that recognises the continuum of possible uranium deposit styles between three families of mineral systems: magmatic-related, 'metamorphic'-related, and basin-related.  Formation of uranium deposits in each family involves fluids of three end-member type: magmatic-hydrothermal, 'metamorphic' (including diagenetic waters and fluids reacted with metamorphic rocks at elevated temperatures), and surface-derived fluids such as meteoric waters, seawater, lakewater and groundwater.  By better understanding the fundamental geological and geochemical processes involved in ore formation in each family of uranium mineral systems, the most important geological 'symptoms' can be recognised and mapped.  This mineral systems approach has been applied to magmatic-related uranium systems in Australia.  The predictions of potential suggest that the under-representation of magmatic-related uranium resources relative to other parts of the world with similar geology may be due not to low endowment but to lack of discovery.

NTGS SpiritHills 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 NTGS Delamere and Spirit Hills, NT, 2015 in units of parts per million (or ppm). The data used to produce this grid was acquired in 2015 by the NT Government, and consisted of 96790 line-kilometres of data at 400m line spacing and 80m terrain clearance.

Ord Valley AEM Interpretation Project - ATLAS of  Weaber plains, Knox Plains and Keep River

In 2008, the Ord Irrigation Cooperative commissioned an airborne electromagnetics (AEM) survey of the ORIA Stage 1 and 2 areas to identify, quantify and understand any potential salinity risks in the current Ord irrigation area and the parts of the catchment that have been identified as potential future irrigation sites or potentially impacted by future irrigation. The project has been funded by the Australian and Western Australian governments through the National Action Plan for Salinity and Water Quality. Geoscience Australia and CSIRO were contracted to carry out the analysis and interpretation of the AEM dataset, and produce customised interpretation products.
Some of the more specific questions it was hoped to address included:
- Are we at risk of salinity in the Ord Catchment?
- If so what areas are at the greatest risk?
- Where can we target management to reduce this risk?
- How can we plan future development to minimise salinity risk and maximise longevity of projects?
The areas surveyed include the current Stage 1 Ord Irrigation Area, Stage 2 Irrigation Area (including Weaber and Knox Plains and Carlton Hill - Parry's Lagoon Conservation Area.  The inclusion of undeveloped land in this survey is because the technology provides the opportunity to ensure any future irrigation development is guided by the best available information on soil type, aquifer quality and location and salinity risk. 
The information generated by this project will be publicly available and can be used for such things as: 
- Identifying leaky areas in the landscape that may require more concentrated management or can be designated for more suitable land use;
- Where salt is stored in the landscape and at what depth, and where in the landscape it may influence plant growth;
- Provide new constraints on the connectivity of aquifer systems in 3D across the ORIA and enable the construction of more realistic hydrogeological models to improve surface and groundwater management.

Laverton-Edjudina airborne magnetic and radiometric survey, Western Australia, 1969

An airborne magnetic and radiometric survey of the LAVERTON and EDJUDINA 1:250,000 map areas was flown in 1966 to assist the systematic regional geological mapping of the Western Australian Precambrian Shield, and the search for metals. Virtually the entire magnetic pattern is attributed to differences in magnetic properties between rock units at or near ground level. Geological strikes and the boundaries of major rock units have been interpreted by delineating magnetic trends, by subdividing the area into zones of specified magnetic character, and by assessing the geological significance of these zones by reference to mapped geology.

NSW Geol. Survey, Tamworth, NSW, 1980 (P504), 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 NSW Geol. Survey, Tamworth, NSW, 1980 survey were acquired in 1980 by the NSW Government, and consisted of 10075 line-kilometres of data at 1500m 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.

Probabilistic Seismic Hazard Assessment of Papua New Guinea: 2019 revision

Papua New Guinea (PNG) lies in a belt of intense tectonic activity that experiences high levels of seismicity. Although this seismicity poses significant risks to society, the Building Code of PNG and its underpinning seismic loading requirements have not been revised since 1982. This study aims to partially address this gap by updating the seismic zoning map on which the earthquake loading component of the building code is based. We performed a new probabilistic seismic hazard assessment for PNG. Among other enhancements, for the first time together with background sources, individual fault sources are implemented to represent active major and microplate boundaries in the region to better constrain the earthquake-rate and seismic-source models. The seismic-source model also models intraslab, Wadati-Benioff zone seismicity in a realistic way using a continuous slab volume to constrain the finite ruptures of such events.
The results suggest a high level of hazard in the coastal areas of the Huon Peninsula and the New Britain–Bougainville region, and a relatively low level of hazard in the southern part of the New Guinea Highlands Block. In comparison with the seismic zonation map in the current design standard, it can be noted that the spatial distribution used for building design does not match the bedrock hazard distribution of this study. In particular, the high seismic hazard of the Huon Peninsula in the revised assessment is not captured in the current building code of PNG.
We will also discuss how the seismic hazard map of PNG is being used to underpin its building code, including what steps have been taken by GA together with the Government of PNG to promote uptake of the new hazard map by PNG’s earthquake engineering community.

AUSGeoid98 v.1.0 data files:  (sg57-06)

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.

Proterozoic intrusive breccia bodies near Duchess, northwestern Queensland

Several breccia bodies consisting of randomly oriented angular to rounded fragments of locally derived amphibolite-grade metamorphic rocks dispersed in an igneous-textured pink matrix occur in the southern part of the Proterozoic Mount Isa Inlier, where they have been mapped as Mount Philp Breccia. The fragments in the breccia can be matched with rocks in the adjacent Corella Formation, a unit of mainly calc-silicate rocks. The breccia matrix contains stubby phenocrysts of tremolite and small miarolitic cavities set in a ground mass of interlocking albite laths. The breccia bodies postdate the deformation and metamorphism of the enclosing Corella Formation, and are thought to fill pipes and fissures formed by explosive releases of pressure during intrusion of magma into calc-silicate rocks at depth.
