Generation of high-quality data for energy, minerals and groundwater by Geoscience Australia’s laboratories

One of the aims of the Exploring for the Future (EFTF) program is to characterise the geochemistry of sedimentary and volcanic units, overbank sediments and groundwater in northern Australia to de-risk resource exploration and inform decision making. Underpinning this effort has been the generation of high-quality geochemical data from Geoscience Australia’s laboratories. A streamlined workflow from sample collection to reporting ensures that samples are processed consistently and to a high standard, and use of rigorously tested methodologies and appropriate QA/QC practices ensures data quality. This abstract highlights many of the processes undertaken in the laboratories, ranging from new sample preparation procedures (including automated milling and setting up temporary remote processing facilities) to organic geochemistry, mineralogy, inorganic geochemistry and geochronology. The laboratories were also instrumental in assisting with fieldwork, outsourcing sample analyses and storing data in corporate databases. The large volume of new data generated over the EFTF program has been used to characterise the geology and geochemistry of a range of rocks, regolith, oils, gas and groundwater, and has been instrumental in increasing knowledge of the resource potential of northern Australia and informing decision making.
