Classification of micas from the Lithium-rich Tuff and other volcanic and intrusive rocks from the Macusani Volcanic Field (this study and6,10,12) in (A) Mg-Li–Fetot + Mn + Ti-VIAl binary diagram after35 and (B) Fe + Mg + Mn–Al–Li and (C) (CFe + Mg + Mn–Al–Li ternary diagrams after36. Lithium contents were measured by LA-ICP-MS, except for TEM-AEM measurements on lepidolite. For some literature data, Li values were calculated from EPMA measurements following35.
