Australian National Radiometric Data Collection

This data collection is comprised of radiometric (gamma-ray spectrometric) surveys acquired across Australia by Commonwealth, State and Northern Territory governments and the private sector with project management and quality control undertaken by Geoscience Australia.
The radiometric method measures naturally occurring radioactivity arising from gamma-rays. In particular, the method is able to identify the presence of the radioactive isotopes potassium (K), uranium (U) and thorium (Th). The measured radioactivity is then converted into concentrations of the radioelements K, U and Th in the ground. 
Radiometric surveys have a limited ability to see into the subsurface with the measured radioactivity originating from top few centimetres of the ground. These surveys are primarily used as a geological mapping tool as changes in rock and soil type are often accompanied by changes in the concentrations of the radioactive isotopes of K, U and Th. The method is also capable of directly detecting mineral deposits. For example, K alteration can be detected using the radiometric method and is often associated with hydrothermal ore deposits. Similarly, the method is also used for U and Th exploration, heat flow studies, and environmental mapping purposes such as characterising surface drainage features. The instrument used in radiometric surveys is a gamma-ray spectrometer. 
This instrument measures the number of radioactive emissions (measured in counts per second) and their energies (measured in electron volts (eV)). 
Radiometric data are simultaneously acquired with magnetic data during airborne surveys and are a non-invasive method for investigating near-surface geology and regolith.

Geology of the Lissadell

These data are a digital representation of information depicted on the printed map of the Lissadell 1:250 000 Geological Series produced by AGSO and the Geological Survey of Western Australia (GSWA) in 1968.
Data present include geological polygons (litho-stratigraphic units), linear structural features (faults, dykes, folds, trends, lineaments etc), and point features (mines, structural points etc). Polygons have a range of attributes extracted from each individual map including unit name, age and lithological description, while lines and points are feature coded according to the AGSO publication 'Symbols Used On Geological Maps' (BMR 1989). A standard look-up table of AGSO geological codes and associated descriptions is available (see ADDITIONAL METADATA).
The data has gradually evolved from elementary CAD quality data into its present topologically structured GIS format, and hence has many imperfections and inconsistencies. Data has undergone rigorous validation and testing that includes over 80 different tests. See ADDITIONAL METADATA for more information on the data standards used.

Angas Bremer Hills 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 0.00021 degrees (approximately 21m) and shows uranium element concentration of the SMMSP - MagSpec - Angas Bremer Hills, SA, 2002. (2002/01) in units of parts per million (or ppm). The data used to produce this grid was acquired in 2002 by the SA Government, and consisted of 5092 line-kilometres of data at 100m line spacing and 60m terrain clearance.

Deep Structure of the East Malita Graben Region - Western Arafura and Northern Timor Seas : Cruise Proposal : Project 121.39

The East Malita cruise is part of a program designed to determine the structural architecture ofthe northwestern margin of Australia and the influence of structuring on the location of,migration and trapping of hydrocarbons in the region. The major objectives of the East MalitaGraben project are:
1) determine the regional structural framework of the eastern Timor Sea region by examiningthe boundaries between the major structural elements along a series of transects;
2) provide modern regional seismic tie lines through the wells in the region to facilitateprovince wide correlations;
3) determine the deep crustal structure of the Malita and Calder Grabens;
4) examine the effects of the deep crustal structure and its reactivation on the location of theknown petroleum accumulations.
To examine these problems it is proposed that the R V Rig Seismic be used to collect a total ofapproximately 3000 km of deep crustal multichannel seismic and other geophysical data along 17lines in the East Malita Graben region. The proposed lines tie all 8 wells in the region plusTuatara-1 and Kulka -1 to the east. The lines are designed to examine the major structuralrelationships in the region. Where possible the lines are orthogonal to the principal trends in theregion.

L033 Latrobe Valley experimental seismic reflection and refraction survey, VIC, 1958

An experimental seismic survey using both refraction and reflection techniques was carried out in April, 1958, near Morwell in the Latrobe Valley at the request of the State Electricity Commission of Victoria. The object of the survey was to find if the method was of value in mapping the structure of the coal measures of the Latrobe Valley and in providing information on the depth to and type of basement underlying the coal measures. 
Work was concentrated in an area south-west of Morwell on the southern limb of the Latrobe Syncline. The results obtained indicate that the seismic method may be applied successfully to geological problems of the Latrobe Valley and may provide useful control data for the interpretation of surface geological and gravity mapping. Various interpretations of the results are discussed and although some ambiguity exists, it might be overcome when more work is done, particularly if an accurate knowledge of the velocities of the coal  easures is obtained. It has been possible by means of refraction work to map the extension of the basalt which crops out on the southern margin of the Latrobe Syncline beneath the coal measures with reasonable certainty.

AUSGeoid98 v.1.0 data files: Webb (sf52-10)

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.

Application of USGS ShakeCast for Rapid Post-Earthquake Assessment of Critical Infrastructure Facilities in Western Australia

The National Earthquake Alerts Centre (NEAC) at Geoscience Australia (GA) operationally provides alerts on earthquake events in the region which include Shakemap. This paper describes a pilot project in the NEAC to provide added information to these alert products to give indications to key asset owners of potential damage. The USGS ShakeCast is an example of such a system that uses USGS Shakemap and provides near-real-time post-earthquake impact and inspection metrics for critical infrastructure facilities following an event. This enables asset owners and infrastructure operators to prioritise damage inspections. GA is undertaking a project entitled “Risk Assessment and Mitigation Study for Earthquakes in the Yilgarn” (RAMSEY) in a collaboration with the Global Earthquake Model Foundation (GEM) and five Western Australian government partners. The key focus of the project was to understand critical infrastructure system risk with geographically dispersed assets in the Yilgarn region in land from Perth. One key issue raised by project partners is the need to effectively prioritise inspection resources following an earthquake where there are many assets exposed to strong shaking. As a response to this need, the USGS ShakeCast application has been operationalised in the NEAC as a pilot for the RAMSEY partners using the vulnerability knowledge developed through the project on bridges. In this paper the input requirements for the system and the products provided are described in the context of a scenario event. Furthermore, the benefits and limitations of the system are discussed along with feedback from the partners on utility in informing the potential development of a broader capability.

The geology of the Canberra City district

This Bulletin is a summary of the geological history of the Canberra City District and serves as an explanation to the accompanying geological and tectonic maps. The original text was accidentally destroyed, together with all records except the maps here presented and one showing the locations of all studied outcrops (totalling 340); the collection of fossils, except for some graptolites, is still intact. The summary for the A.N.Z.A.A.S. Handbook (Opik, 1954) was compiled from the original text and served as a basis in rewriting the present Bulletin. Because of subsequent building operations, many of the destroyed records cannot be restored. The geological map requires some comment. The map is correct insofar as the visible sequence is concerned; where the sequence is obscured by faults it reflects the author's interpretation to satisfy all the circumstantial evidence - structural, lithological, and palaeontological - so far available. The accuracy of the boundaries is not absolute: small outcrops of weathered, or even fresh, rocks (for example, calcareous mudstones) do not provide all criteria for their formational classification and, in marginal cases, have had to be classified according to the boundary already inferred, and not vice versa; some portions of the boundary between the Turner Mudstone and the Riverside Formation are so treated.

Dunmarra, NT, 2014 (P1268), 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 Dunmarra, NT, 2014 survey were acquired in 2014 by the NT Government, and consisted of 104017 line-kilometres of data at 400m line spacing and 80m 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.
