Description

This dataset contains sedimentological and geochemical data for 43 surficial sediments sampled from Lake Albert, South Australia (-35.6, 139.3); one of the two 'Lower Lakes' that constitute the River Murray Estuary. Specifically, this dataset includes laser diffraction grain-size data (43 samples; Malvern Mastersizer 2000), loss-on-ignition data (43 samples), near-total (aqua regia digestion) concentrations for elements Al, S, V, Cr, Mn, Fe, Co, Ni, Cu, Pb and the REEs (43 samples), sequential extraction data for elements Al, V, Cr, Mn, Fe, Co, Ni, Cu, Pb and the REEs (27 sandy silt samples (subset of collected samples)), and Fe(II)/Fe(III) data (26 sandy silt samples). Al, V, Pb, and the REEs were analysed in all extracts using inductively coupled plasma mass spectrometry (ICP-MS; Perkin-Elmer NexION 350X), while S, Cr, Mn, Fe, Co, Ni, and Cu were analysed using inductively coupled plasma optical emission spectrometry (ICP-OES; Varian 720-ES). All geochemical data is in ppb units. This dataset accompanies the paper: Job, T., Penny, D., Morgan, B., 2020.
