AUSGeoid98 v.1.0 data files: Darwin (sd52)

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 Data format: AUSGeoid98 data files have a header record at the start of each file, to distinguish them from the superseded AUSGeoid93 data files. AUSGeoid98 data files show the geoid-ellipsoid separation to 3 decimal places, while the superseded AUSGeoid93 data files showed only 2 decimal places.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.

The Precambrian mineral belt of north-western Queensland

This bulletin presents the results of a geological survey carried out jointly by the Bureau of Mineral Resources and the Geological Survey of Queensland, and it is a pleasure to record the large measure of friendly co-operation which has attended the investigation at all times. The Bulletin is presented, for convenience, in two volumes: Volume I contains the text and accompanying illustrations, and Volume II is an atlas. The survey began in 1950 and systematic field work was largely completed in 1954. However, since 1953 the region has undergone notable development; the opening of Mount Isa Mines Ltd's copper smelter in 1953 led to the reopening of many old copper 'shows' and the search for others; the discovery of uranium in 1954 initiated a year of spectacular activity and resulted in the location of the important Mary Kathleen uranium deposit; and extensive testing of the Constance Range iron deposits gives promise of large-scale development. Investigations connected with these developments, detailed mapping of several areas, and considerable regional check work in the years 1955-58 have added greatly to our knowledge and understanding of the region; the results are incorporated in the bulletin. As the Precambrian of North-Western Queensland forms an entity and had not previously been systematically described and interpreted as a unit it was deemed necessary to give a full account of the region, including details of climate, topography, vegetation, and history. A lengthy report has resulted. For ease of use the bulletin has therefore been designed as a reference book, with more or less self-contained sections. This form of presentation has inevitably led to a fair amount of repetition. It is hoped that the bulletin will prove useful to a wide variety of readers, who will seek to obtain very varied information from it. By use of the detailed list of contents, appendices, and the geographical index it is hoped that all readers will be able to find readily the information they require. To help further the bulletin has been divided into two parts: Introduction and General Geology, on the one hand, and Economic Geology, on the other. An outline of the geology, and the geological history, is given for the general reader on pp. 36-55. In Part II brief descriptions of the surface expression and the secondary zone of mineral deposits are given to help the prospector evaluate surface and shallow sub-surface indications.

GSWA Dumbleyung Nyabing Merge ppm 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 Dumbleyung-Nyabing-Coblinine merge, 2002-2005 in units of parts per million (or ppm). The data used to produce this grid was acquired in 2002 by the WA Government, and consisted of 27617 line-kilometres of data at a line spacing between 100m and 400m, and 50m terrain clearance.

Geophysical Data Collection - elevation

Digital Elevation Model data record the terrain height variations from the processed point-located data recorded on an airborne geophysical survey.  The aircraft altimeter data records the height of the aircraft above the ground and the aircraft GPS records the height of the aircraft above the ellipsoid.  Subtracting the two values enables the height of the terrain beneath the aircraft relative to the ellipsoid to be calculated.  This ellipsoidal terrain height is corrected for the variation between the ellipsoid and the geoid (the n-value correction) to produce terrain heights relative to sea level.

Estimates of Geological and Geophysical Surfaces (EGGS) database

The EGGS database contains point depths to chronostratigraphic surfaces obtained from boreholes and four magnetic modelling methods. In regards to the depths obtained from inclined boreholes there are uncertainties on their measurement of the true vertical depths. These are currently being  looked into and would be resolved in due course. Future development will include AEM, reflection seismic, MT and passive seismic. A Web Service will allow the public to download this data and will be accessed through the EFTF (Exploring for the Future) web portal.

Grey Range Seismic Survey, Queensland, 1959 By L. H. Smart Oil Exploration Company Limited

A seismic reflection survey was conducted on behalf of L.H. Smart Oil Exploration Company Limited by Geosurveys of Australia Ltd during 1959. The survey consisted of a number of shot-points placed at one or two-mile intervals along lines across the Canaway anticline, the Pinkilla anticline, and the Chesson (Orient) anticline of the Grey Range.
The purpose of the survey was to provide detailed information of the subsurface structure of anticlines indicated by surface geology. The survey was interpreted with reference to geology known from the Bulgroo bore on the western limb of the Canaway anticline.
Seismic operations clearly indicated that surface fold structure continues and is enhanced with depth; the anticlines are caused by buried ridges, probably with Precambrian core-rocks. Permian to Cretaceous sediments are draped over these ridges and have a minimum thickness of about 4,000 it across the Canaway anticlinal crest; in the adjoining trough syncline, they thicken rapidly to 10,000 it or more.

Tallaringa North - TMI grid (AWAGS)

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 Tallaringa North - TMI grid (AWAGS) has a cell size of 0.00042 degrees (approximately 44m). The units are in nanoTesla (or nT). The data used to produce this grid was acquired in 2017 by the SA Government, and consisted of 98230 line-kilometres of data at 200m 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.

AusAEM: imaging the near-surface from the world’s largest airborne electromagnetic survey

Real advances in understanding geology for mineral, energy and groundwater resource potential of the Australian continent will come from unveiling what lies at depth, especially in the extensive under-explored regions that are obscured by cover. In this context, airborne electromagnetics (AEM) is a geophysical method at the forefront in addressing the challenge of exploration undercover. In collaboration with the state and territory geological surveys, Geoscience Australia has led a national initiative whose goal is to acquire AEM data at 20 km line spacing across Australia. This initiative, AusAEM, represents the world’s largest AEM survey flown to date; it has covered ~2.5 million km2, a substantial part of northern Australia, and is providing new insights in areas that have not been extensively explored. Regional models of subsurface electrical conductivity derived from AusAEM data support a range of applications that include geological mapping, mineral and petroleum exploration, watershed management and environmental studies.
