SEM back-scattered electrons (SEM-BSE) images (A-B) and quantified X-ray maps generated by EPMA showing chemical zoning (C-I) in a mica crystal clast in a sample of Lithium-rich Tuff, with a zinnwaldite core and a narrow lepidolite rim. The locations of Raman analyses R1 and R2 provided in Fig. S5 are shown as green dots. Abbreviations33: Cldn—“chalcedony”; Kln—kaolinite; Mca—mica; Mnz—monazite; Zrn—zircon.
