The National Geochemical Survey of Australia (NGSA) has collected samples from 1315 sites located in 1187 catchments (~10% of which were sampled in duplicate) covering over 80% of Australia. At each site, two depth ranges were sampled and two grain size fractions were separated, giving 5260 samples to be analysed. Samples were analysed for: 1 - Total content of multiple elements in Geoscience Australia's laboratories using x-ray fluorescence (XRF) and inductively coupled plasma-mass spectrometry (ICP-MS) 2 - total content of fluoride (F) in commercial laboratories using ion specific electrode (ISE) 3 - total content of platinum group elements (PGEs) in commercial laboratories using fire assay and ICP-MS 4 - aqua regia soluble content of selenium (Se) in a commercial laboratory using ICP-MS 5 - aqua regia soluble content of multiple elements, including low-level gold (Au), in a commercial laboratory using ICP-MS 6 - ligand-based extractable content of multiple elements in a commercial laboratory using ICP-MS. The detailed procedures for analysing the NGSA samples in various laboratories are described.
