1. Cue and Kirkalocka airborne geophysical survey

Geoscience Australia has called tenders for an airborne geophysical survey of the Cue and Kirkalocka 1:250 000 map sheets, Western Australia. The service comprises acquisition, processing and supply of approximately 55,437 line kilometres of high resolution airborne magnetic, gamma-ray spectrometric and elevation data. Information derived from these geophysical data will be used to assist in the mapping of the Archaean geology and is aimed at stimulating exploration activity in this prospective region of Australia. The survey data will be acquired on east-west flight lines spaced 400 metres apart and the nominal terrain clearance will be 60 metres above ground level and covers an area between 117.0 and 118.5 degrees east and -28.25 and -27.0 degrees south. The tender opens on February 24, 2004 and closes on March 16, 2004.

2. New airborne geophysical data for the Burakin region, WA

Geoscience Australia has released new airborne geophysical data on the Burakin region, WA, that will be used to better understand the region's deep geological structures, to assist in geological and environmental soil mapping and to help understand regional earthquake activity. Data in this release comprise magnetic, gamma-ray and elevation located data and grids from a survey flown for Geoscience Australia in June 2003 and from three private company surveys flown between December 1996 and February 1997. The company data has been levelled with the Burakin survey data to create a combined dataset giving a continuous coverage. The data can be downloaded for free using the Geophysical Archive Data Delivery System (GADDS) or purchased on two CD-ROMs from the Geoscience Australia Sales Centre at for the cost of A$99 per CD (including GST; postage and packing extra).

3. Australian Geological Provinces Database

The Australian Geological Provinces Database contains descriptions and polygon outlines of geological provinces of the Australian continent and surrounding offshore regions. The provinces are mapped at a nominal 1:1 million scale.

The database can be interactively queried, and the results retrieved as reports and maps. Attributes include igneous, sedimentary and structural characteristics, age limits, parent and constituent units, relations to surrounding provinces, and mineral and petroleum resources. Note that the Provinces Database is still under construction and doesn't contain a complete coverage of all geological provinces. The picture at left shows the current coverage of the provinces database. If you wish to add to this national database, you can download and send in the Geological Provinces database entry template.
