Notes. The Δ χ2 values refer to the sequential changes obtained by adding the parameters from top to bottom and from left to right: O ii, O iii, ..., O viii, Metallic Fe, ..., Fe SO4.
The Δ χ2 given by pyroxene Mg Si O3 is small because its features are similar to those produced by H2 O ice (see also Fig. 7).
