Legacy stream sediment sample reanalysis - Red River, Hann River, Ebagoola, Coen, Georgetown, Kakadu, Araluen, Brindabella, Hedleys Creek, and Mammoth Mines Surveys

<div>Geoscience Australia has a large holding of surface sediment samples, such as stream and overbank sediments, from geochemical surveys conducted over more than 50 years across the Australian continent. Geochemical data from these surface materials are of national importance as they can contribute significantly to establishing geochemical environmental baselines and their use in land management, as well as aiding in the discovery of new mineral deposits. Samples from these legacy surveys provide valuable insights into areas of Australia that are remote, difficult to access, or have since been developed. The age of a large number of these surveys, however, means that the original results included data for a&nbsp;smaller range of chemical elements, typically with poorer analytical precision and accuracy than those of modern surveys. This small range of chemical elements also typically doesn’t include important elements for modern use, such as critical minerals (i.e. Co, Bi, REEs), which are increasing in their importance. As part of Geoscience Australia’s Exploring for the Future program, a collection of over 9000 samples from these surveys was reanalysed using modern analytical techniques for a&nbsp;suite of 60 chemical elements. These samples cover several regions within Australia, including Kakadu, Cape York, the Mount Isa region, and near the Canberra region. The new analytical data maximise the value of the historical geochemical surveys and will provide new insights into the mineral potential of these regions and improve the quality of geochemical environmental baselines.&nbsp;</div><div><br></div><div>This data release includes: 1) information on the surveys and their samples; 2) quality assurance results; 3) a discussion of sample preparation and analytical methods used; 4) results for total content geochemistry (XRF and LA-ICP-MS); and 5) individual element maps for each of the regions for preliminary interpretation of the data.</div><div><br></div><div>Acquisition and release of this dataset forms part of a larger program aimed at creating a levelled geochemical baseline for the whole Australia (Main and Champion, 2020).</div>

Statement

<div>This data is a reanalysis of legacy stream sediments from across Australia and were originally collected by BMR and AGSO, GA’s predecessor organisations. These samples are housed within GA’s on site sample repository. These samples were re-analysed as part of the Exploring for the Future program to provide a modern range of elements and precision/accuracy. This data will supersede the original data within the inorganic geochemistry database and the data available at portal.go.gov.au. Requests can still be made for the original data as it is kept within the inorganic geochemistry database in a non-visible state.</div><div><br></div>
