AUSGeoid98 v.1.0 data files:  (sk57-11)

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 Data format: AUSGeoid98 data files have a header record at the start of each file, to distinguish them from the superseded AUSGeoid93 data files. AUSGeoid98 data files show the geoid-ellipsoid separation to 3 decimal places, while the superseded AUSGeoid93 data files showed only 2 decimal places.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

Kingston percent potassium 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 potassium grid has a cell size of 0.00083 degrees (approximately 88m) and shows potassium element concentration of the Kingston, WA, 1998 in units of percent (or %). The data used to produce this grid was acquired in 1998 by the WA Government, and consisted of 47325 line-kilometres of data at 400m line spacing and 80m terrain clearance.

pmd*CRC Micrometallogeny of Hydrothermal Fluids F3 Project. Final Project Report

This report is a synopsis of research compiled and carried out within the Predictive Mineral Discovery CRC F3 project "Micrometallogeny of hydrothermal fluids". The F3 project's original objectives were:
(1) Geology-driven terrain and ore fluids investigations to evaluate the chemistry and fluid processes within mineral systems in order to extend the focus of fluid studies beyond direct ore deposit analysis. 
(2) LAICPMS and PIXE technique and methodology development were techniques utilized throughout the project and methodologies were developed for their combined application. (3) Diamond-cell autoclave experiments component of the project was a scoping-collaboration in year one of F3 with the Museum of South Australia.  (4) Database development and fusion with numerical modelling resulted in development of a web-based database for fluid inclusion research has been successful and is currently accessed at http://www.ga.gov.au/minerals/research/methodology/geofluids/flincs_about.jsp

Australian Mineral Blocks 2006 - Geodatabase

The dataset was created by Geoscience Australia using the framework described in Section 33 of the Offshore Minerals Act 1994.
The international, scheduled areas and coastal waters used in this dataset are those found in the historical Australian Maritime Boundary Dataset 2006 (AMB2006).
The dataset is comprised of both polygons and points created to very high precision, accurate to within millimetres.
The blocks have been cut by Australia's international boundaries, the scheduled areas and the coastal waters. Each block is assigned a polygon, including partial blocks. All blocks are titled with their block ID, and a list of vertices that make up the blocks. Each vertex of the dataset is also replicated as a discrete point in the points dataset.
The design of the dataset allows for the exact location of every vertex to be known to millimetre precision. The corner coordinates of blocks are now defined to a high precision, and can be found by querying the appropriate point.
The blocks are attributed with fields containing information on:
-Block ID
-Parent 1 Million Mapsheet
-Offshore Area
-Epoch of the boundaries used to cut the data  AMB2006
-Datum
-Origin of the mapsheet in AGD66
-The position of all vertices in the block
-The number of vertices in the block
-The area of the block in acres
-The area of the block in hectares
The calculation used to find the area of the blocks is estimated to be precise to better than 1%. This is considered to be sufficient as under the permit and licensing arrangements in the Offshore Minerals Act, the area of a block has no relevance. Therefore the area figure is provided solely for reference.
This dataset is published with the permission of the CEO, Geoscience Australia

Wiso Basin tie52, NT, 2000 (P1015), 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 Wiso Basin, NT, 2000 survey were acquired in 2000 by the NT Government, and consisted of 113520 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.

North West Margin Transects : Survey 128 Post-cruise Report

The North West Margin Transects Cruise (Survey 128) forms part of a programbeing undertaken by AGSO to determine the structural architecture of the north-western margin of Australia and the influence of structuring on the location,migration and trapping of hydrocarbons in the region. An important aspect of thisprogram is the acquisition of a series of full margin 'dip transects extending fromunrifted cratonic basement to beyond the continent-ocean boundary, and at leasttwo 'strike' transects that will extend along the full length of the shelf from theeastern Timor Sea to North West Cape. The major objective of Survey 128 was toextend previous AGSO deep-seismic surveys across the Browse (Survey 119),offshore Canning (SNOWS-3/Survey 120) and northern Camarvon basins (SNOWS-1/Survey 101, SNOWS-2/Survey 110) to complete these margin transects.
The survey vessel Rig Seismic left Port Hedland on 30 May 1994. A weather buoy0^was deployed for the Bureau of Meteorology at the beginning of the survey. Seismic acquisition commenced on 4 June 1994. The survey was completed on 25 June0^and finished in Fremantle on 30 June 1994. During the survey, 11 seismic lineswere completed for a total of 3403.05 km at an average of 155 km per day (based on 22 days of acquisition). Transits between lines amounted to more than 800 km. The survey ties into the 1991 SNOWS-1 (101), 1992 SNOWS-2 (110), 1993 Browse Basin (119) and SNOWS-3 (120) deep-seismic surveys, and the 1990 standardrecord length Triassic Reef Survey (95).
The data were recorded from a 4800 m streamer, configured with 192 x 25 m active groups. Data were recorded with a 16 s record length and a 2 ms sample interval.The seismic source consisted of dual sleeve gun arrays with a total capacity of 50 litres, and was fired every 50 metres to give 48-fold CDP coverage. Navigation for the survey was provided by differential Global Positioning System (dGPS), using shore reference stations in Dampier, Broome, Perth and Darwin.
Both the seismic and non-seismic acquisition systems ran without major problems. Navigational data were of good quality, with differential GPS being available for more than 95% of the survey.
