Tambo-Augathella Aeromagnetic And Gravity Surveys, Queensland, 1959-1960 By Magellan Petroleum Corporation

An aeromagnetic survey and a gravity survey were carried out for Magellan Petroleum Corporation in the Tambo-Augathella area of Queensland in 1959-1960. The results of the aeromagnetic survey were reduced, studied, and interpreted by Aero Service Corporation, who had subcontracted Adastra Airways Pty Ltd, to provide the aircraft and also the flying personnel and associated ground staff. The gravity survey was done by Century Geophysical Corporation.
The main objectives of the two surveys were to delineate the thickness of the sedimentary rocks, and to investigate the major geological structures in the area.
The results of the aeromagnetic survey suggested the presence of several structures in the basement rocks. The Nebine Ridge appeared to be quite shallow over most of the area; major east-west trending faults were indicated. The results of the gravity survey did not fully agree with the results of the aeromagnetic survey. The gravity results indicate a central basinal feature bounded on the west by a platform, but the aeromagnetic results indicate deep basement on the north-west and only a few thousand feet of sediments to the south and east. These conflicting results indicate that some additional control, as would be obtained from wells drilled for stratigraphic information, is necessary for evaluation of the respective surveys.

Simpson Extensions - Finke, NT, 2004 (P1061), 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 Simpson Extensions, NT, 2004 survey were acquired in 2004 by the NT Government, and consisted of 34000 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.

AUSGeoid98 v.1.0 data files: Wintinna (sg53-14)

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 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 0.00042 degrees (approximately 41m) and shows uranium element concentration of the North-East Tasmania, Tas, 2007 in units of parts per million (or ppm).

Pendulum measurements of gravity in Australia, 1950-51

During 1950-51 pendulum gravity observations were made at 59 stations throughout Australia using invar pendulums on loan from the Department of Geodesy at Cambridge University. A national gravity base station was established at Melbourne. Subsequent comparisons with gravity meter ties suggest that the pendulum value is about 2 mgal. low. The standard errors of the gravity differences from Melbourne to the other stations have been estimated from internal consistency of the pendulum observations and from comparison with gravity meter measurements; the mean standard error is about 0.6 mgal. A small systematic difference from gravity meter values is assumed to be caused by the effect of the earth's magnetic field on the pendulums; after correction for this, the results agree fairly well with the American calibration system. Free air, Bouguer and isostatic anomalies have been calculated for all stations. The isostatic anomalies are for both Airy-Heiskanen and Pratt-Hayford hypotheses, and for four different assumed crustal thicknesses in each case. The isostatic and Bouguer anomalies are predominantly negative. A degree of isostatic compensation is present, but some large anomalous areas are uncompensated. The pendulum survey forms a basic network to which past and future gravity surveys can be referred.
