Description

Appendix A. Heavy mineral occurrences and abundances of the studied samples Appendix B. Major and trace element compositions of apatite in the studied tuffs analyzed using a wavelength dispersive electron probe (JEOL 8530F). Each measurement was performed on a different crystal grain. Appendix C. Major element compositions of ilumenite in the studied tuffs analyzed using a wavelength dispersive electron probe (JEOL 8530F). Each measurement was performed on a different crystal grain. Appendix D. Summary of LA ICP-MS U–Pb results for zircon from the studied tuffs. Each measurement was performed on a different crystal grain.
