Geophysical mapping using the national airborne and gravity datasets: an example focusing on Broken Hill

The Australian Geological Survey Organisation acquires and maintains extensive databases of airborne magnetic and radiometric surveys, digital elevation models and gravity measurements.  These data can be accessed and processed to present information ranging from continental scale to detail at 1:25 000 scale.  When data relating to the Broken Hill area of New South Wales are imaged it is possible to infer the distribution of similar rocks elsewhere in Australia and possible tectonic origins for the rocks hosting the Broken Hill Ag-Pb-Zn deposit.  Interpretations using 1: 100 000 and 1 :25 000 scale data facilitate the production of detailed solid geology maps.

AUSGeoid98 v.1.0 data files:  (sj51-07)

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 Data format: AUSGeoid98 data files have a header record at the start of each file, to distinguish them from the superseded AUSGeoid93 data files. AUSGeoid98 data files show the geoid-ellipsoid separation to 3 decimal places, while the superseded AUSGeoid93 data files showed only 2 decimal places.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

SA Detailed Gravity Survey 91B5 (P199175), gravity point data

Gravity data measures 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 SA Detailed Gravity Survey 91B5 (P199175) contains a total of 121 point data values acquired at a spacing between 250 and 650 metres. The data is located in SA and were acquired in 1991, under project No. 199175 for None.

Tsunami Animation - Shoaling

As the tsunami leaves the deep  water of the open ocean and approaches the shallower waters near the coast, it slows down and may grow in height depending on the shape of the seafloor.
A tsunami that is unnoticeable by ships at sea may grow to be several metres or more in height near the coast.
Our example tsunami is now 1.5 metres high with a wavelength of 100 kilometres and is moving at about 400 kilometres an hour.

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.

L159 Dubbo (Spicers Creek) 3D-3C high resolution seismic survey, NSW, 2003 Seismic acquisition data for lines 03GA-DB1 and 03GA-DB2

A multicomponent seismic survey using an IVI MiniVib as a source was carried out to assist in mapping of fracture porosity in shear zones in areas of dryland salinity for the School of Biological, Earth and Environmental Sciences (UNSW). The survey obtained a set of three dimensional, three component data at two sites near Spicers Creek, some 45km east of Dubbo.  The acquisition was undertaken by Australian National Seismic Imaging Resource (ANSIR) from the 5th to the 12th April 2003 with the assistance of staff from UNSW. 
The objectives of this seismic survey are:
1.  Develop quantitative measure of azimuthal anisotropy of P- and S-waves using refracted head wave amplitudes. 
2.  Determine the relative effects of lithological fabric and fracture porosity on P- and S-wave anisotropy factors.
3.  Determine quantitative relationships between azimuthal anisotropy and fracture porosity.
4.  Measure the horizontal and vertical variability of the fracture porosity in the fracture zones which control the discharge of saline groundwater and the occurrence of dryland salinity at the three experimental sites in the Spicers Creek Catchment.
5.  Develop cost-effect field techniques for 3D - 3C (three dimensional - three component) shallow seismic refraction surveys for geotechnical, environmental and groundwater applications.
