The results presented here provide new insights into the petrogenesis of the PPB and call for a general reassessment of emplacement ages and source characteristics of the other alkalic intrusive centers in the batholith. Zinnwaldite is a lithium-iron mica [KLiFe +2 Al(AlSi 3 O 10)(F,OH) 2] that is common as euhedral, pseudohexagonal books in miarolitic cavities (pockets) of pegmatites of the Precambrian (~1.05 Ga) Pikes Peak Batholith (Eckel and others, 1997; Foord and Cerny, 1995).
