Tennant Creek 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 0.00042 degrees (approximately 45m) and shows uranium element concentration of the Tennant Creek, NT, 1998 in units of parts per million (or ppm). The data used to produce this grid was acquired in 1998 by the NT Government, and consisted of 98200 line-kilometres of data at 200m line spacing and 60m terrain clearance.

Clay modelling of the Fitzroy Graben

Parallel shear, generated by sliding tongue and grooved boards past each other with clay on top produced, initially - in addition to the commonly recognised conjugate strike slip faults - a set of gently plunging folds at 30-45Â° to the wrench zone. Essentially vertical Riedel shears may subsequently become part of reverse drag structures as rotation of the clay, in response to the shearing couple, introduces a tensional component. A single right-lateral movement in the model has reproduced the orientation of the major faults and folds within the Fitzroy graben of the Canning Basin. Major features such as the offshore depression on the southern margin of the Leveque shelf and part of the Halls Creek mobile zone may have been produced, as simulated in the model, by major dextral wrenching and, in the case of the Leveque shelf, by later subsidence of basement rocks. Absorption of lateral movement by the Halls Creek mobile zone may account for the less deformed, more platform-like northeast Canning Basin.

AUSGeoid98 v.1.0 data files:  (sj53-13)

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.

L045 Rosedale No. 1 Bore, A.P.M  Seismic survey , VIC, 1960

A seismic velocity survey of the APM Development Pty Limited No. 1 bore at Rosedale, Victoria, was made by the Geophysical Branch of the Bureau on the 3rd May 1960 using a TIC three-component well geophone. Measurements were taken with the geophone suspended in the well at selected intervals down to 5500 ft. It was apparent that signals reached the geophone by transmission along the cable by which it was suspended, and these interfered with the signals reaching the geophone along a path directly through the ground. This made interpretation difficult; however, by careful inspection of both the vertical and horizontal components of the signals received by the geophone at each depth, an interpretation has been made that yields a series of velocity/depth determinations. The average vertical velocity increases from 5000 ft/sec at the surface to 8930 ft/sec at a depth of 5500 ft. The average velocity in the Tertiary (0-2159 ft below datum) was computed to be 6420 ft/sec; the -werage velocity in the Mesozoic rocks penetrated (2159-5314 ft below datum) was 12,180 ft/sec. Two reflection spreads laid out and recorded in the vicinity of the bore showed the presence of reflectors at depths estimated to be in excess of 7700ft.

NE Queensland (Georgetown, Einasleigh, Ingham), Qld, 1982-84. (P481), 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 NE Queensland (Georgetown, Einasleigh, Ingham), Qld, 1982-84. survey were acquired in 1982 by the QLD Government, and consisted of 36607 line-kilometres of data at 1500m line spacing and 150m 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.

Typically, where a map produced on standard sheet lines is largely ocean it is combined with its landward neighbour. These maps contain natural and constructed features including road and rail infrastructure, vegetation, hydrography, contours (interval 50m), localities and some administrative boundaries. The topographic map and data index shows coverage of the sheets. Product Specifications Coverage: The series covers the whole of Australia with 513 maps.

The Furneaux Group, Bass Strait&nbsp;bathymetry survey was acquired for the Australian Hydrographic Office (AHO) using Cessna 441 during the period 11 Apr 2022 – 20 Nov 2022. This was a contracted survey conducted for the Australian Hydrographic Office by Fugro Australia as part of the Hydroscheme Industry Partnership Program. The survey area encompases an area in Furneaux Group, Bass Strait. Bathymetry data was acquired using a LADS HD+ / LADS HD / RIEGL VQ-820-G, and processed using RIEGL RiProcess and CARIS HIPS and SIPS processing software. The dataset was then exported as a 30m resolution, 32 bit floating point GeoTIFF grid of the survey area.
This dataset is not to be used for navigational purposes.
