Lake Eyre - ground elevation geoid grid (radar)

Digital Elevation data record the terrain height variations from the processed point- or line-located data recorded during a geophysical survey. This Lake Eyre - ground elevation geoid grid (radar) is elevation data for the Lake Eyre Airborne Magnetic Radiometric and DEM survey, SA, 2017. This survey was acquired under the project No. 1302 for the geological survey of SA. The grid has a cell size of 0.0004 degrees (approximately 42m).  This grid contains the ground elevation relative to the geoid for the Lake Eyre Airborne Magnetic Radiometric and DEM survey, SA, 2017. It represents the vertical distance from a location on the Earth's surface to the geoid. The data are given in units of meters. The processed data is checked for quality by GA geophysicists to ensure that the final data released by GA are fit-for-purpose.

Hazard Impact Assessment: HazImp

The HazImp system enables users to analyse the impact of natural hazards.  HazImp is capable of assessing the impact of a range of hazards including, but not limited to, floods and tropical cyclones.  HazImp uses a set of pre-processed inputs, perform logic based analysis using predefined models and produce a range of quantitative outputs.  These inputs may be produced by existing external systems including hazard modelling applications.  HazImp outputs may include aggregated values, statistical figures, diagrams and spatial maps to describe the impact of the natural hazard to the study area. 
HazImp assesses the impact of a natural hazard as a combination of three fundamental elements:
•   Hazard - the type of hazard and its properties;
•   Exposure - elements that are or could be subject to the hazard;
•   Vulnerability – an element’s physical or social susceptibility to the hazard.
All three elements are required to properly assess the impact of a hazard and a change in any element will affect the impact results.  HazImp supports a set of inputs, each corresponding to one of these three elements.  HazImp is designed to support a wide variety of scenarios making it highly customisable to the event or events being analysed.  In particular, HazImp is compatible with existing GA systems.
HazImp supports two primary business cases for natural hazard impact assessment.  The first, to support risk assessment and mitigation where system response times can be generous and could be as long as weeks.  The second, is forecasting the impact of an imminent event, where an assessment is needed in real-time.

Bonney Well 6, NT, 1999 (P1008), 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 Bonney Well, NT, 1999 survey were acquired in 1999 by the NT Government, and consisted of 165222 line-kilometres of data at a line spacing between 200m and 200m, and 60m 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.

Gravity evidence for abrupt changes in mean crustal density at the junction of Australian crustal blocks

The major gravity anomalies in central and western Australia occur as elongate dipoles, either in isolation or in a series. Each dipole is thought to be caused by an abrupt change in mean crustal density at the junction of two crustal blocks and by the associated isostatically compensating masses. Typically one block has along its margin a strip with anomalously high mean crustal density, and the other block has normal density crust covered by several kilometres of low density sediment. The observed anomalies are consistent with the anomalous masses being isostatically compensated by variations in the thickness of the crust, the crustal thickness variations being gradual and extending to about 100 km from the boundaries of the anomalous bodies. The crustal block boundaries inferred from dipole anomalies correspond in position with the crustal block boundaries inferred from geology, and approximately with the position of block boundaries inferred from changes in the gravity trend pattern. Usually the block with younger basement has high density material along its margin, and the other, older block is covered with sediment; both these features are likely to be caused by the process that created or emplaced the younger block. The presence of relatively dense material high in the crust along the margins of the younger blocks suggests that younger blocks are not superficial features on a uniform old crust. The dipole anomalies on the Australian Precambrian crust are similar in magnitude and tectonic position to those recognised at Precambrian province boundaries in Canada.

Geological relationships and 40Ar/39Ar age constraints on gold mineralisation at Tarcoola, central Gawler gold province, South Australia

The Tarcoola Goldfield is one of several districts included in the recently proposed central Gawler gold province. Understanding of the genesis of the deposits in this metallogenic province is in its infancy, and dating the age of alteration, mineralisation and microdiorite dyke intrusions has been carried out at Tarcoola as a first step towards developing mineral-systems models for the province. At Tarcoola, four samples of sericite from alteration as well as one sample of hornblende from a microdiorite dyke yield 40Ar/39Ar ages of ca 1580 Ma. Geological and petrological relationships suggest that this age represents the time of fracture-controlled Au mineralisation. These data provide evidence for coeval Au mineralisation, microdiorite dyke intrusion and local deformation. This mineralisation age is indistinguishable from U-Pb ages for the regional Gawler Range - Hiltaba volcano-plutonic complex, and is more than 100 million years younger than the Paxton Granite, which is part-host to the mineralisation. Possible temporal and genetic relationships with other deposits in the central Gawler gold province remain to be tested.

Adavale Basin region: Key geological surfaces and intervals package

Publicly available geology data are compiled to provide a common information base for resource development, environmental and regulatory decisions in the Adavale Basin region. This data guide gives examples of how these data can be used and supports the data package that provides the existing knowledge of the key geological intervals of the Adavale Basin and the overlying Galilee, Eromanga and Lake Eyre basins.
The key geological intervals identified by the Trusted Environmental and Geological Information (TEGI) Program for resource assessment and groundwater system characterisation are termed play intervals and hydrostratigraphic intervals respectively. The Adavale Basin includes 8 plays, which are consolidated into 1 hydrostratigraphic interval. Overlying the Adavale Basin are 5 play intervals of the Galilee Basin, which are consolidated into 3 hydrostratigraphic intervals; 9 play intervals of the Eromanga Basin, which are consolidated into 7 hydrostratigraphic intervals; and 1 Cenozoic play interval and 1 hydrostratigraphic interval for the Lake Eyre and other Cenozoic basins. The geological groups and formations included in the plays and hydrostratigraphic intervals are summarised in the stratigraphic charts of Wainman et al. (2023a).
Gross depositional, depth structure and thickness maps are provided with 3D model and cross-sections summarising the geology of the Adavale Basin and the overlying basins. The mapped depths and thicknesses of the key intervals are used to inform resource assessments and provide the framework for assigning groundwater data to hydrostratigraphic intervals.
