Rock geochemistry and Isotopes from the Georgina Basin: Exploring for the Future – East Tennant NDI drillholes

<div>This report contains new whole-rock and isotope (Pb and Sr) geochemical data, associated sample metadata, an assessment of the data’s quality assurance, for 76 samples collected from the Georgina Basin of the East Tennant National Drilling Initiative (NDI) in 2021. The data can be downloaded via the Geoscience Australia EFTF portal ( https://portal.ga.gov.au/persona/eftf) or in the files attached with this record ( http://pid.geoscience.gov.au/dataset/ga/148954).</div><div><br></div><div>This new geochemistry data release builds on the success of the East Tennant NDI, addressing the data-gap in earlier geochemical sampling of these holes, by providing whole-rock geochemistry (and Pb+Sr isotopes) for the Georgina Basin cover sequence. Improved geochemical characterisation of Georgina Basin geology is valuable from both a hydrogeological and mineral systems perspective. The Georgina Basin extends across much of the Northern Territory and into western Queensland, comprised of Cryogenian to Devonian sediment packages.</div><div><br></div><div>Geoscience Australia’s Exploring for the Future program provides precompetitive information to inform decision-making by government, community and industry on the sustainable development of Australia's mineral, energy and groundwater resources. By gathering, analysing and interpreting new and existing precompetitive geoscience data and knowledge, we are building a national picture of Australia’s geology and resource potential. This leads to a strong economy, resilient society and sustainable environment for the benefit of all Australians. This includes supporting Australia’s transition to net zero emissions, strong, sustainable resources and agriculture sectors, and economic opportunities and social benefits for Australia’s regional and remote communities. The Exploring for the Future program, which commenced in 2016, is an eight year, $225m investment by the Australian Government.</div><div><br></div>
