AUSGeoid98 v.1.0 data files:  (se48-08)

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 Data format: AUSGeoid98 data files have a header record at the start of each file, to distinguish them from the superseded AUSGeoid93 data files. AUSGeoid98 data files show the geoid-ellipsoid separation to 3 decimal places, while the superseded AUSGeoid93 data files showed only 2 decimal places.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

Quantitative methods for interpreting aeromagnetic data: a subjective review

Although rapid and relatively accurate graphical techniques exist for interpreting the depth to magnetic sources, these have now been largely supplanted by a wide range of computerised forward modelling routines capable of giving detailed estimates of source geometry as well as the source depth.  Computer routines which have automated the depth estimation process also exist; however, these require considerable judgement on the part of the user, as they can give misleading results.

Australian and Soviet gravity surveys along the Australian Calibration Line

The Australian Calibration Line (ACL) , with a total gravity interval of 3 Gal, was established during 1970 between Laiagam in Papua New Guinea and Hobart in Tasmania. During 1973 the Australian Bureau of Mineral Resources and the USSR Geodesy and Cartography Survey made joint observations along the full length of the ACL. Measurements made with eight Soviet GAG-2 gravity meters established a gravity scale for Australia to an accuracy of 2.5 parts in 105. This scale and a datum of 979 671.86 mGal for Sydney A were adopted for Australia in 1973. The Soviet scale established for the ACL appears to be within 1 part in 104 of both the IGSN71 scale established for the Western Pacific Calibration Line by absolute determinations, pendulum measurements and international gravity meter comparisons, and the scale established for the Soviet Calibration Line by OVM pendulums. The Soviet scale for the ACL defines a milligal which is 1.5 parts in 104 larger than that defined by IGSN71 values for the ACL, and 5 parts in 104 larger than the 1965 Mean Australian Milligal that was used as an Australian milligal standard between 1965 and 1973. Both of these scales are partly based on Cambridge pendulum measurements made in Australia during 1950-51. These measurements are now thought to have been incorrect in scale. LaCoste, Romberg gravity meters have been used during six surveys along the whole or part of the ACL. The LaCoste observations have been reduced using the Soviet ACL scale and the new datum for Sydney A. The most probable values for airport gravity stations, calculated from the LaCoste results, have a precision of better than 0.01 mGal and are consistent to within experimental error with values calculated from the GAG-2 results. LaCoste observations reduced using the Soviet ACL scale give more accurate values for the gravity differences of the main intra-city ties and calibration ranges along the ACL.

North Central Tasmania elevation grid (south) geodetic

Digital Elevation data record the terrain height variations from the processed point- or line-located data recorded during a geophysical survey. This North Central Tasmania elevation grid (south) geodetic is elevation data for the North Central Tasmania, Tas, 1999. This survey was acquired under the project No. 699 for the geological survey of TAS. The grid has a cell size of 0.00042 degrees (approximately 40m).  This grid contains the ground elevation relative to the geoid for the North Central Tasmania, Tas, 1999. It represents the vertical distance from a location on the Earth's surface to the geoid. The data are given in units of meters. The processed data is checked for quality by GA geophysicists to ensure that the final data released by GA are fit-for-purpose.

GSQ Isa Georgetown Block C Qld 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 0.00096 degrees (approximately 103m) and shows uranium element concentration of the Isa-Georgetown Block C,QLD, 2000, Prospectivity Plus Initiative in units of parts per million (or ppm). The data used to produce this grid was acquired in 2000 by the QLD Government, and consisted of 45601 line-kilometres of data at a line spacing between 200m and 400m, and 80m terrain clearance.

Eastern Creek volcanics as the source of Copper at the Mammoth Mine, northwest Queensland

At the Mammoth mine, epigenetic copper mineralisation occurs within the Myally Subgroup of the Haslingden Group, an arenaceous sequence that both includes and overlies basic volcanics. A basic flow in the Myally Subgroup is altered, being enriched in potassium and copper for up to 200 m from the mineralisation. However, underlying metabasalts of the Eastern Creek Volcanics up to 600 m from the mineralisation are depleted in iron and copper and enriched in potassium relative to those further away. Evidence is presented that the Mammoth ore represents copper leached from the Eastern Creek Volcanics and transported along the Mammoth-Mammoth Extended Fault system. This hypothesis is similar to one previously proposed for the copper mineralisation at Mount Isa, although there are differences in the age and lithology of the host rocks in the two areas. Thus, rocks adjacent to major faults transgressing the Eastern Creek Volcanics must be considered prospective for copper mineralisation.

Comparisons betweenVs30 and Spectral Response for 30 sites in Newcastle, Australia from collocated Seismic Cone Penetrometer, Active- and Passive-Source VS Data

Although the time-averaged shear-wave velocity down to 30 m depth (Vs30) can be a proxy for estimating earthquake ground-motion amplification, significant controversy exists about its limitations when used as a single parameter for the prediction of amplification. We make an extensive use of different methodologies as blind comparisons in order to question the applicability of amplification factor as defined by Vs30, for 30 sites in the Newcastle area, Australia. The multi-method approach includes past seismic cone penetrometer (SCP) and spectral analysis of surface waves (SASW), with newly acquired horizontal-to-vertical spectral ratio (H/V), passive source surface-wave spatial autocorrelation (SPAC), refraction microtremor (ReMi) and multichannel analysis of surface waves (MASW) data. We show that Vs30 can be related with spectral response but not necessarily with the maximum amplification. Transition zones within the geological boundaries may be important factors affecting site effects. Both Vs30 and amplification factor (AF) values are influenced by the velocity ratio between bedrock and overlying sediments and the presence of surficial thin low velocity layers (STL) (&lt; 2m thick and &lt; 150 m/s), but the velocity ratio is what affects mostly the AF. At 0.2 &lt; T &lt; 0.4 s, the AFs are largely influenced by surficial geology. For T &gt; 0.5 s, amplification curves follow the order expected for hard to soft site classes. The SPAC and ReMi techniques have the smallest deviation from the average for all sites, corresponding to a factor of &lt; 0.5 for &gt; 75% of the data.

Mildura, Vic, 1994 VIMP Survey (GSV3019) (P638), 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 Mildura, Vic, 1994 VIMP Survey (GSV3019) survey were acquired in 1994 by the VIC Government, and consisted of 51663 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.
