Aspects of the Lithium-rich Tuff and lithium mica crystal clasts hosted therein. (A) Photograph of a typical rock sample from this unit. (B) Medium to coarse ash-sized, dark brown to black mica crystal clasts stand out against the pale tuffaceous mudstone background. (C-F) SEM backscattered electron (SEM-BSE) images of a mica crystal clast embedded in a very fine-grained matrix. Abbreviations33: Cldn—“chalcedony”; Afs—alkali feldspar; Kln—kaolinite; Mca—mica; Lpd—lepidolite; Tpz—topaz; Znw—zinnwaldite; Zrn—zircon.
