Notes: CSIRO = Commonwealth Scientific and Industrial Research Organisation, ICP-AES = inductively coupled plasma–atomic emission spectroscopy, ICP-MS = inductively coupled plasma–mass spectrometry, INNA = instrumental neutron activation analysis. Units as noted in column headings except where otherwise noted. DL = detection limit (cited where close to or exceeding some values). Sample 142807 had a white residue present on dissolution; S and Pb may be underestimated. Roman Ruins chimney results are an average of 50 subsamples, from Binns et al. (2000), plus additional data; Si result for Roman Ruins chimneys is an average of 37 subsamples, from Moss and Scott (2001). * = by ICP-AES, † = unreliable data, ‡ = by INNA, unaffected by dissolution problem, ** = by ICP-MS. See Table T1 for ODP sample identifications for CSIRO numbers.
