Tanami EW 5N - TMI RTP 1VD 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 Tanami EW 5N - TMI RTP 1VD grid (AWAGS) is the first vertical derivative of the TMI RTP grid of the NTGS Tanami EW 5N Region Detailed Airborne Magnetic Radiometric and Digital Elevation Survey, NT, 2018 survey.
This grid has a cell size of 0.00018 degrees (approximately 20m) , and given in units of nT per metre (nT/m).  The data used to produce the TMI grid was acquired in 2018 by the NT Government, and consisted of 11735 line-kilometres of data at 100m line spacing and 60m terrain clearance. The data has had a variable reduction to the pole applied to centre the magnetic anomaly over the magnetised body. The VRTP processing followed a differential reduction to pole calculation up to 5th order polynomial. Magnetic inclination and declination were derived from the IGRF-11 geomagnetic reference model using a data representative date and elevation representative of the survey. A first vertical derivative was calculated by applying a fast Fourier transform (FFT) process to the TMI RTP grid of the NTGS Tanami EW 5N Region Detailed Airborne Magnetic Radiometric and Digital Elevation Survey, NT, 2018 survey to produce this grid. This grid was calculated using an algorithm from the INTREPID Geophysics software package. This grid shows the magnetic response of subsurface features with contrasting magnetic susceptibilities. The grid can also be used to locate structural features such as dykes.

The near-surface sediments of the Scott plateau and Java Trench: nannofossil assessment and implications

Quaternary sediments are apparently more widespread and better represented in the northern Scott Plateau and Java Trench than in parts of the central Scott Plateau, where older rocks are exposed on the sea floor. Nevertheless, wherever Quaternary calcareous nannofossils are recovered from these areas, they are associated with reworked Upper Cretaceous and Tertiary forms. This may have been caused by bottom currents actively eroding parts of the central Scott Plateau and redistributing the fine fraction elsewhere on the plateau, Java Trench and nearby areas. These currents may have been active from the middle Miocene. Late Pleistocene to Holocene calcareous nannofossils occur throughout the near-surface (ca 1 m thick) sediments in the northern Scott Plateau, but are absent from such sediments in the Java Trench. However, Pleistocene nannofossil assemblages, older than those from the Scott Plateau, occur intermittently at lower levels in the near-surface (ca 1 m thick) sediments in the Java Trench. This difference is explained by suggesting that the present Nanno Solution Depth lies between 3290 m and 4950 m water depth in the Scott Plateau and Java Trench areas, but in earlier Quaternary times it fluctuated between 5090 m and 5424 m in the same areas.

AUSGeoid98 v.1.0 data files:  (sd50-03)

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.

Integrated geological and geophysical mapping of southwestern Western Australia

The major basement components within the Albany 1:1M Sheet area of southwestern Western Australia are defined from aeromagnetic anomalies and 10-40 km wavelength gravity anomalies, and are integrated with mapped geology to provide a geological model. Their structure (lithological banding), faults and dykes are determined from short-wavelength magnetic anomalies. The main tectonic elements are the Archaean Yilgarn Craton, the younger Albany Province to the south, and the Perth Basin with Proterozoic basement to the west.  The Yilgarn Craton comprises an eastern zone with strike-extensive sinuous anomalies, typical of granite-greenstone terrane, and a western zone with sparse, short anomalies, characteristic of granite-gneiss terrane. Highly magnetised granulites along the eastern margin of the western zone correlate with outcrop of the Jimperding Metamorphic Belt in the north of the sheet. The eastern boundary of these granulites is parallel to a weak gravity gradient, and corresponds with a significant change in structural style; it is inferred to be a major intra-cratonic discontinuity. A north-northwest-trending gravity gradient within the western zone coincides with the Southwest Seismic Zone, and defines the eastward extent of thick, relatively dense crust defined by earlier studies of seismic refraction data.  The Albany Province consists of a low-density southern zone with weakly sinuous magnetic banding, and a northern zone characterised by high-density, high-magnetisation, and linear magnetic banding. The southern margin of the Yilgarn Craton has been deformed for up to 50 km and demagnetised up to 20 km from the boundary. This deformation is inferred to have been caused by overthusting of the Albany Province during the Mid-Proterozoic. Subsequently, tectonism involving the Proterozoic crust beneath the Perth Basin deformed the western edge of the Yilgarn Craton and folded adjacent parts of the Albany Province southward.  Greenstone and metamorphic belts are highly prospective and host many of the regions mineral deposits. Both the composition and geophysical characteristics of these belts contrast with those of more widespread granite and granite-gneiss terrane, which are of considerably lower economic interest. Analysis of the regional geophysical data sets in co njunction with outcrop geology leads to a more complete model of the Precambrian geology of the region than that derived from outcrop mapping alone.
