Correlations between pairs of variables that are both elemental data are not included here. Only correlations for which p < 0.05 are presented here. When multiple variables are listed in the “by Variable 2” column, this means that both Kendall τ and Prob > | τ| values are the same between Variable 1 and all variables listed in “by Variable 2” column.
