Figure 10: Factor loadings of principle component analysis (64 samples, 31 chemical elements). Factor I (xaxis, 59.6 % of the variance) includes high positive factor loadings for Ba, Bi, Ce, Cs, Hf, K, La, Li, Mo, Na,
Nb, Rb, Sb, Ta, Th, Tl, U, W, Y, and Zr and high negative factor loadings for Ca, Co, Fe, Mg, Ni, Ti, and V.
Factor 2 (y-axis, 11.8 % of the variance) is characterized by high positive factor loadings for Cs, Hf, Sb, Ti, and
Zr and a negative Mn factor loading.

Figure 11: Factor scores of principle component analysis (64 elements, 31 chemical elements). Factor 1 (x-axis)
clearly separates the Khatanga basin, whereas factor 2 differentiates between Lena and Yana basin.
