- Sheet 3: Bulk rock composition, normalised composition, and fresh and altered domain calculated composition of sample PT22A.
- Sheet 4: Sample PT22A altered and fresh domain composition calculations.
- Sheet 5: Summary of maximum, average and minimum concentration of trace elements in each mineral of sample PT22A.
- Sheet 6: Mass transfer estimate through a stoichiometric and visual estimate of phase proportion and maximum, average, and minimum concentrations of trace elements in each mineral in the reaction.
Appendix N – Chapter 5 Pinitization data
