Magnetic investigations of compass swinging sites at the RAAF aerodrome Laverton, Victoria

The purpose of the investigation was to determine the degree of uniformity of the earth's magnetic field over the existing and the alternate compass swinging sites for ground swinging of aircraft. Field work was carried out on 30/1/51 and 5/2/51. Instruments used were the Vertical Force Variometer and the Wingfield Compass. The report gives an account of the field work and the results of the survey.

Southeast Lachlan, NSW, 2010 (P1218), radiometric line data, AWAGS levelled

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 Southeast Lachlan, NSW, 2010 (P1218), radiometric line data, AWAGS levelled were acquired in 2010 by the NSW Government, and consisted of 108251 line-kilometres of data at a line spacing between 250m and 500m, 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.

AUSGeoid98 v.1.0 data files:  (sc49-02)

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 Data format: AUSGeoid98 data files have a header record at the start of each file, to distinguish them from the superseded AUSGeoid93 data files.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.

MRTAS Bass Strait magnetic 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 Bass Strait magnetic grid geodetic has a cell size of 0.00167 degrees (approximately 164m). The units are in nanoTesla (or nT).

Results of coal-drilling Surveyor Creek area - southern portion, Newcastle region, New South Wales

This statement supplements Record 1952/3 by H.B. Owen, which recorded the preliminary results of drilling for open-cut coal in the northern part of Portion 11, Ph. Stockrington near Newcastle, N.S.W. A further 33 holes, entailing 3,220 feet of drilling, were sunk in an area of about 430 acres immediately south of the area reported  on by Owen. The majority of the holes were drilled into the Borehole Seam: two encountered only the beds below the Borehole Seam, and a number of holes encountered seams which may be the Australasian, Dudley, Yard, and Sandgate Seams. The results of the drilling indicate that the Borehole Seam is not suitable in this area for open-cut mining because of present high quality coal standards; however the lower plies of the seam, averaging 3 feet 6 inches in total thickness may be suitable for underground mining over a limited area of at least 25 acres. Total indicated reserves in this area are only 130,000 long tons (calculated on the basis of 1,500 tons per acre foot); the quality of the coal would be only fair: calorific value of about 11,500 B.Th.U/lb., ash content about 20%, and the coal would have some coking properties. Further drilling may increase this as workable area. It is considered that the preliminary results did not justify extensive prospecting of the Australasian(?), Dudley(?), Yard(?), or Sandgate Seams.

Uranium mineral systems: processes, exploration criteria, and a new deposit framework

Australia holds the world's largest resources of uranium recoverable at low cost, principally in the uranium-rich Olympic Dam iron oxide Cu-Au (IOCG) deposit together with the Ranger and Jabiluka unconformity-related deposits and Yeelirrie surface-related deposit.  Despite this impressive inventory, resources of several other styles of uranium deposits appear to be under-represented in Australia relative to geologically similar regions elsewhere in the world.  In particular, Australia has no known giant uranium deposits hosted by Mesozoic or younger sedimentary basins, although recent discoveries in the Frome Embayment have significantly increased total resources of `sandstone' uranium in the region.  Major deposits directly related to magmatic processes also appear to be under-represented, given the abundance of unusually uranium-rich igneous rocks in Australia.  The Australian Government's Onshore Energy Security Program (OESP 2006-2011) is providing pre-competitive geoscientific data and new area selection concepts to assist in reducing exploration risk and to support an assessment of onshore energy and uranium potential.  
This report examines the key processes controlling where and how uranium mineralisation occurs in Australia and elsewhere.  Based on this process understanding and on descriptions of well-documented systems, we develop generalised models of three distinct families of uranium mineral systems, including exploration criteria.  The purpose of the report is to present a revised framework for a fresh assessment of Australia's uranium mineral potential.  This systems-based approach, when combined with empirical data, provides a means of identifying previously unrecognised uranium provinces or districts.    
The report has three parts.  First, the fundamental chemical controls on uranium transport and deposition in aqueous geological systems are reviewed.  Second, a new scheme of classification of uranium deposits is proposed (see below).  Third, each of three families of uranium mineral systems, plus hybrid systems, is described in terms of ore-forming processes, essential components of the mineral system, and mappable criteria.  Exploration models for key systems are presented in figures and tables.
