Prospecting activities Edith River area: progress report for period 7th to 17th July, 1953

The area prospected is shown in plan on Plate 2 and a locality map is given in Plate 1. The prospecting was done by geologists D.E. Gardner and N.O. Jones, and survey hands S.J. Quain of the geological party, and B. Brewster and E. Rigby of the geophysical party. In order to cover the area systematically, it was subdivided into small topographic units, bounded by such features as creeks and the crest of ridges. Each unit of the area was traversed by one or more members of the prospecting party, who used Geiger-counters or ratemeters to test shear zones and outcropping quartz veins for radio-activity. Prospects were examined by either of the two geologists, who also made general notes on the geology of each unit of the prospecting area. Twelve uranium prospects were discovered within an area 4 miles long by 1.25 miles wide in Cullen granite adjacent to the contact with Brocks Creek sediments. An additional prospect was previously known to occur there. They are all small, and judging from the surface counts, appear to be low in grade.

Tanami NS 1D - U equivalent concentration grid (AWAGS, nasvd)

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 0.00018 degrees (approximately 20m) and shows uranium element concentration of the NTGS Tanami NS 1D Region Detailed Airborne Magnetic Radiometric and Digital Elevation Survey, NT, 2018 in units of parts per million (or ppm). The data used to produce this grid was acquired in 2018 by the NT Government, and consisted of 2188 line-kilometres of data at 100m line spacing and 60m terrain clearance. To constrain long wavelengths in the grid, an independent data set, the Australia-wide Airborne Geophysical Survey (AWAGS) airborne magnetic data, was used to control the base levels of the survey grid.

Seabed environments and shallow geology of the Vlaming sub-basin, Western Australia - interpreted geomorphic map.

Geoscience Australia undertook a marine survey of the Vlaming Sub-basin in March and April 2012 to provide seabed and shallow geological information to support an assessment of the CO2 storage potential of this sedimentary basin. The survey was undertaken under the Australian Government's National CO2 Infrastructure Plan (NCIP) to help identify sites suitable for the long term storage of CO2 within reasonable distances of major sources of CO2 emissions. The Vlaming Sub-basin is located offshore from Perth, Western Australia, and was previously identified by the Carbon Storage Taskforce (2009) as potentially highly suitable for CO2 storage. The principal aim of the Vlaming Sub-basin marine survey (GA survey number GA334) was to look for evidence of any past or current gas or fluid seepage at the seabed, and to determine whether these features are related to structures (e.g. faults) in the Vlaming Sub-basin that may extend up to the seabed. The survey also mapped seabed habitats and biota in the areas of interest to provide information on communities and biophysical features that may be associated with seepage. This research addresses key questions on the potential for containment of CO2 in the Early Cretaceous Gage Sandstone (the basin's proposed CO2 storage unit) and the regional integrity of the South Perth Shale (the seal unit that overlies the Gage Sandstone). This dataset comprises an  interpreted geomorphic map.

MRTAS Pipers River tmi grid geodetic

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.
This MRTAS Pipers River tmi grid geodetic has a cell size of 0.0005 degrees (approximately 49m). The units are in nanoTesla (or nT). The data used to produce this grid was acquired in 1993 by the TAS Government, and consisted of 16797 line-kilometres of data at 200m line spacing and 80m terrain clearance.

Extent of Archaean and Late Proterozoic Rocks under the ice cap of Princess Elizabeth Land, Antarctica, inferred from Geophysics

A helicopter survey has mapped gravity and magnetic anomalies and ice thickness over a 100 km by 100 km ice cap area, inland from coastal outcrops of Archaean and Late Proterozoic rocks of the Princess Elizabeth Land coast. The gravity and magnetic anomalies indicate that there is no major change in crustal structure across the boundary between Archaean and Lake Proterozoic rocks. The Archaean rocks of the Vestfold Hills do not extend further inland, but they may extend under Prydz Bay or as a narrow coastal strip under ice inland from the West Ice Shelf, 150 km to the northeast of the Vestfold Hills. Late Proterozoic rocks probably underlie most of the ice cap along the coast.

Radiometric Map of Australia Edition 3 - A3 hardcopy version

Geoscience Australia and State and Territory Geological Surveys have systematically surveyed most of the Australian continent over the past 40 years using airborne gamma-ray spectrometry to map potassium, uranium and thorium elemental concentrations at the Earth's surface. However, the individual surveys that comprise the national gamma-ray spectrometric radioelement database are not all registered to the same datum. This limits the usefulness of the database as it is not possible to easily combine surveys into regional compilations or make accurate comparisons between radiometric signatures in different survey areas. 
To solve these problems, Geoscience Australia has undertaken an Australia-Wide Airborne Geophysical Survey (AWAGS), funded under Geoscience Australia's Onshore Energy Security Program, to serve as a radioelement baseline for all current and future airborne gamma-ray spectrometric surveys in Australia. The AWAGS survey has been back-calibrated to the International Atomic Energy Agency's (IAEA) radioelement datum. We have used the AWAGS data to level the national radioelement database by estimating survey correction factors that, once applied, minimize both the differences in radioelement estimates between surveys (where these surveys overlap) and the differences between the surveys and the AWAGS traverses. The database is thus effectively levelled to the IAEA datum. The levelled database has been used to produce the first 'Radiometric Map of Australia' - levelled and merged composite potassium (% K), uranium (ppm eU) and thorium (ppm eTh) grids over Australia at 100m resolution. 
Interpreters can use the map to reliably compare the radiometric signatures observed over different parts of Australia. This enables the assessment of key mineralogical and geochemical properties of bedrock and regolith materials from different geological provinces and regions with contrasting landscape histories.
The Radiometric Map of Australia is available as a free PDF or JPG (2nd edition),  and as an A0 printed wall map (1st edition) which can be purchased from  the Geoscience Australia Sales Centre.
The gridded digital data which underpins the Radiometric Map of Australia is available free of charge for download using the Geophysical Archive Data Delivery System (GADDS). Because the grids are large (approximately 5.5 GB each), users planning to access entire grids at full resolution should contact minerals@ga.gov.au to arrange alternative means of acquiring the digital data.

Storage and retrieval systems for the Reference Minerals Collection and the Georgina Basin Project

Two major information storage and retrieval systems now in operation at the Bureau of Mineral Resources - the Reference Minerals Collection Index and the Georgina Basin Project Data Base - are based on INFOL. The first system, used in progressively indexing mineral specimens in the BMR Museum, has been in operation 5 years and will continue indefinitely. The second system, designed for a specific field project, has been in operation for 4 years and has a finite life. The systems are run through CSIRONET on the Cyber 76 computer. INFOL (described in detail in CSIRO Division of Computing Research Manuals) is a generalised information storage and retrieval system designed to create, maintain, and interrogate a file of information. Basically, it is a free-field language which allows items of information of variable length to be written in plain English. It does not require the use of 80-column coding forms; data are stored in a compressed form - blank fields and non-significant blanks in the data do not take up storage space; complex search strategies are possible; and the report generators are flexible. Output may be obtained as a written report on visual display units, paper or microform, or as input for other computer applications. The major phases of an INFOL system are ESTABLISHMENT, INTERROGATION, UPDATE, and BOOKKEEPING. During the ESTABLISHMENT phase a file (i.e., a list) of elements (e.g., mineral specimens) consisting of a number of items (identification and descriptive information) is created. The file can then be interrogated or updated. Retrieval criteria can apply to items or sub-items - testing for the existence or non-existence of data, or testing relational criteria. The file may be updated by adding new elements; removing existing elements; adding, removing or changing items; or adding or changing sub-items. BOOKKEEPING occurs automatically at certain stages of INFOL operations. It gives information essential for specifying report formats.
