Note the strong correlation between the lithogenic tracers yttrium (Y), potassium (K), iron (Fe), aluminum (Al) and titanium (Ti) with 232-thorium (232Th) and the reduced correlation of 232Th with magnesium (Mg), calcium (Ca), barium (Ba) and strontium (Sr) in panels (e) – (i) and (a) – (d), respectively. Linear regressions, Pearson’s r and two-tailed p-values (all <0.0001) calculated for n = 139 samples. Grey shadings indicate 95% confidence intervals. See also Methods for more details.
