The Western Australia shear zone

Tectonic geomorphology along the continental margin of Western Australia indicates the presence of an approximately 2000 km long zone of dextral-oblique neotectonic faults and folds referred to as the Western Australian shear zone (WASZ). The WASZ reoccupies older rift related structures that initially formed during periods of continental-scale fragmentation in the Paleozoic and Mesozoic Eras. Reactivation in the WASZ is coincident with late Neogene reorganization of Australia’s plate boundaries and realignment of the intraplate stress field. Neotectonic deformation in the southern WASZ is dominated by transpressional inversion within the extended crustal domain between Australian oceanic crust to the west and non-extended Australian continental crust to the east. The WASZ appears to accommodate differential motion expressed as dextral transpression between oceanic and non-extended continental tectonic blocks—or micro-plates.

AlbanyFraserNth CompleteSphCapBouguer geodetic 1vd

Gravity data measure small changes in gravity due to changes in the density of rocks beneath the Earth's surface. 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 AlbanyFraserNth CompleteSphCapBouguer geodetic 1vd is the first vertical derivative of the complete spherical cap Bouguer anomaly grid for the Albany Fraser Gravity Survey (P201062). This gravity survey was acquired under the project No. 201062 for the geological survey of WA. The grid has a cell size of 0.005 degrees (approximately 519m). A Fast Fourier Transform (FFT) process was applied to the original grid to calculate the first vertical derivative grid.  A total of 9258 gravity stations at 2500m spacing were acquired to produce this grid.

Regolith of the Cape York Peninsula, North Queensland (CYPLUS project)

This map was compiled at 1:250,000. Each polygon has regolith and landform types as minimum attributes. The dataset contains the arc/info files, a copy of the CYPLUS report, and a copy of the GA regolith mapping handbook.
Regolith in the CYPLUS area in North Queensland consists of both in situ weathered bedrock and transported materials. In situ weathered bedrock includes:
1. Deep weathering profiles with bauxite, mottled and pallid zones, found on remnant land surfaces
2. Residual sand over moderately weathered saprolite in areas of relatively low geomorphic activity
3. Thin soils lying directly on slightly weathered or unweathered bedrock on steeper slopes and unstable areas
Transported regolith includes:
1. Large areas of alluvium in fans in the east, and a small area of slightly dissected fan alluvium in the south west
2. Narrow strips of alluvium, with occasional terraces, along the major rivers
3. Coastal sediments (beach ridges and estuarine sediments)
4. Small areas of colluvium in footslopes below steeper hill slopes
Iron cementing forms immature ferricrete in a few locations. Siliceous cementing is more widespread, both in present valley floors, and as silcrete in alluvium that now caps small remnant land surfaces.

Revision of the Kerguelen Plateau bathymetric grid

This record was superseded on 13/02/2023 with approval from the Director, National Seabed Mapping as it has been superseded by eCat 147703
The existing regional bathymetric grid of the Kerguelen Plateau, south-west Indian Ocean, was updated using new singlebeam echosounder data from commercial fishing and research voyages, and some new multibeam swath bathymetry data. Source bathymetry data varies from International Hydrographic Organisation (IHO) S44 Order 1a to 2. The source data were subjected to area-based editing to remove data spikes, then combined with the previous Sexton (2005) grid to produce a new grid with a resolution of 0.001-arcdegree. Satellite-derived datasets were used to provide island topography and to fill in areas of no data. The new grid improves the resolution of morphological features observed in earlier grids, including submarine volcanic hills on the top of the Kerguelen Plateau and a complex of submarine channels draining the southern flank of the bank on which Heard Island sits. The Heard and McDonald Islands are situated on the Kerguelen Plateau and lie within Australia's marine jurisdiction.This dataset is not to be used for navigational purposes.

AUSGeoid98 v.1.0 data files: Camden Sound (sd51-15)

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.
