1. (a) Dot map showing the distribution of the top Jenks class of the Spearman correlation coefficients (rs > 0.54; red circles) of NGSA AR samples with respect to the marine limestone-derived Nullarbor reference sample (# ; star symbol).
(a) Dot map showing the distribution of the top Jenks class of the Spearman correlation coefficients (rs > 0.54; red circles) of NGSA AR samples with respect to the marine limestone-derived Nullarbor reference sample (# ; star symbol). Samples from all other classes are shown as grey circles. Location of the Eucla geological region is shown in the background (magenta polygon) as are outlines of the other geological regions of Australia (Blake & Kilgour 1998). (b) Histogram showing the distribution of rs values relative to the Nullarbor sample together with the mean (µ), standard deviations (σ) and Jenks class boundaries.
