Rock geochemistry from the Curnamona Province and Delamerian Orogen
This report contains new whole-rock and isotope geochemical data, associated sample metadata, an assessment of the data’s quality assurance, for 742 samples collected in and around the Curnamona and Delamerian provinces, across numerous drillcore sampling campaigns through 2021-23. 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/148651).
Geochemical sampling in the Curnamona region straddles both South Australia and New South Wales. The objective of sampling was to obtain representative coverage (both stratigraphically and spatially) to support developing regional geochemical baselines (in conjunction with existing geochemistry). Thus, this sampling included both the Curnamona Province and the overlying basins (Eromanga Basin, Lake Eyre Basin). Whole-rock geochemistry is reported for 562 samples, with a subset of 13 samples analysed for Pb and Sr isotopes, and another subset of 36 samples analysed by thin section petrography (all presented herein).
Geochemical sampling in the Delamerian region has focussed on available legacy drill core in South Australia, New South Wales and Victoria. The objective of sampling was to (systematically) constrain the geochemical character of magmatic rocks across the mainland extent of the Delamerian Orogen, as well as younger volcanics within the Delamerian Orogen and/or overlying cover. This geochemical sampling was conducted in conjunction with geochronology, mineral systems sampling and stratigraphic drilling (all components of the DCD project) to reinterpret the timing, character and fertility of the Delamerian Orogen. Whole-rock geochemistry is reported for 180 samples.
Version 2.0 (published 28 November 2023) has added whole rock geochemistry for 22 new samples in the Delamerian region. The data products and report have been updated accordingly.

<div>This data is primarily new geochemistry data from legacy drillholes accessed from the Broken Hill (GSNSW) and Tonsely (GSSA) core libraries.</div><div>It also includes a subset of reanalysed rock geochemistry from outcrop and seismic traverse powders archived in Geoscience Australia were originally collected by BMR and AGSO, GA’s predecessor organisations. </div><div>These samples were 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 (where applicable) within the inorganic geochemistry database and the data available at portal.ga.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>
Version 2.0 (published 28 November 2023) has added whole rock geochemistry for 22 new samples in the Delamerian region. The data products and report have been updated accordingly
