This product is the single largest AGSO funded stream sediment geochemical data set available in Australia. The data covers roughly 80 000 square kilometres of Proterozoic and Phanerozoic north Queensland and contains 235 914 analyses of 8752 samples. This product also includes PDF files of the associated reports and atlases.

Statement: The sediment samples were collect by BMR/AGSO field parties 1972-93 by vehicle or helicopter traverse. Samples were sieved at base camp (1972-80) or on site (1990-3) with -180 micron (1972-93) and -1mn (1990-3) fractions collected. Samples were analysed in BMR/AGSO laboratories by x-ray fluorescence spectrometry (XRFS) and atomic absorption spectrophotometry (AAS) (1972-93), and by inductively coupled plasma-mass spectrometry (ICP-MS, Analbs, Perth, 1990-3) and bulk cyanide leach for Au (BLEG, ALS, Brisbane, 1990-3). Navigation within the field was by air photo overlays (1972-80) and by GPS (1990-3). Samples sites were translated to the then current 1:100k maps and digitised.
