  abstract = {{T}ypically found in rare-metal granites and pegmatites, lithium micas are increasingly considered a resource for lithium as global demand surges. {I}n a recently discovered major lithium resource within the {M}acusani {V}olcanic {F}ield in {P}eru, lithium mica crystal clasts hosted by a tuffaceous mudstone represent an important ore constituent. {T}he mm-scale mica clasts comprise a zinnwaldite core and a lepidolite rim. {C}ompositionally similar to micas in global peraluminous, rare-metal-rich leucogranites and {LCT} pegmatites, they exhibit enrichment in incompatible, fluid-mobile lithophile elements relative to micas in other volcanogenic and intrusive units in the {M}acusani {V}olcanic {F}ield. {T}he compositions of the mica crystal clasts record high degrees of magmatic differentiation and exsolution of a magmatic vapor phase during their crystallization in a ligand-rich, peraluminous crystal mush. 40{A}r/39{A}r dating of zinnwaldite-lepidolite crystal clasts reveals cooling between 8823 +/- 9 and 8717 +/- 44 ka, coinciding with a regional magmatic lull in the {C}entral {A}ndes of southern {P}eru. {A} general slowdown in magmatic activity and a hiatus in volcanism may have contributed to extreme differentiation and pre-eruptive volatile build-up. {T}his study provides crucial insights for lithium exploration, highlighting volcanogenic-sedimentary lithium mica deposits as a promising exploration target in peraluminous volcanic fields.},
