1. (a) Dot map showing the distribution of the top Jenks class of the Spearman correlation coefficients (rs > 0.52; red circles) of NGSA AR samples with respect to the mafic/ultramafic dominated Kalgoorlie reference catchment (# ; star symbol).
(a) Dot map showing the distribution of the top Jenks class of the Spearman correlation coefficients (rs > 0.52; red circles) of NGSA AR samples with respect to the mafic/ultramafic dominated Kalgoorlie reference catchment (# ; star symbol). Samples from all other classes are shown as grey circles. Distribution of outcropping mafic to ultramafic igneous rocks from the 1:5 000 000 scale Surface Geology of Australia dataset (Shaw et al. 2000) is shown in the background (green polygons) as are outlines of geological regions of Australia (Blake & Kilgour 1998). (b) Histogram showing the distribution of rs values relative to the Kalgoorlie sample together with the mean (µ), standard deviations (σ) and Jenks class boundaries. Locations discussed in text are shown.
