    rruff.info/rruff_1.0/uploads/AM89_888.pdf Ferriwhittakerite is present as relic cores in complex Li-rich amphiboles. Growth replacement and fracture replacement tex-tures are widely observed, where the inner Na-rich and Fe-poor compositions are subsequently replaced by Na-poor and Fe-rich amphiboles. Ferriwhittakerite is bluish black, with vitreous luster. It has
