New National Geoscience Datasets in Australia: Geology, Geophysics and Geochemistry In 2006, the Australian Government announced a new Energy Security Initiative, which led to the establishment, among others, of the Onshore Energy Security Program (OESP) at Geoscience Australia. This Program, which has a budget of A$58.9 million over 5 years, is deploying several data acquisition programs (seismic, radiometric, magneto-telluric, airborne electromagnetic, and geochemical) to attract investment in exploration for onshore petroleum, geothermal, uranium and thorium energy resources in Australia (Johnson 2006). Three new, national-scale geoscience initiatives are under way in Australia with the aim to provide energy and mineral explorers with state-of-the-art pre-competitive data and information about the continent's potential resources. (1) A digital geological map provides a seamless and consistent coverage of geological units at 1:1,000,000 scale. It is underpinned by a national stratigraphic index database to ensure uniform and consistent unit description and classification and nomenclature usage. (2) An Australia-wide airborne geophysical survey that has been used to level all of Australia's public-domain radioelement data to a common datum. This enables interpreters to make accurate comparisons between radiometric signatures in different parts of the continent. (3) A low-density geochemical survey aims to provide a national geochemical data layer using consistent sampling medium and methods, as well as consistent sample preparation and analysis. Large-scale geochemical patterns thus revealed are hoped to point to new areas of exploration potential. The two latter projects are funded under the Australian Government's Onshore Energy Security Program. Together, these three national geoscience datasets will help make Australia a more attractive destination for energy and mineral exploration investments.
