Abstract

Two compositionally and petrographically distinct populations of ilmenite-ecandrewsite solid solution, FeTiO3 - ZnTiO3, coexist in a kyanite-bearing schist from the Black Mountains, Death Valley. The first population is extremely zinc-rich and has the stoichiometric formula (Zn0.17-0.81Fe0.18-0.64Mn0.01)TiO3. The mineral is orange-brown in transmitted light, and occurs both as inclusions in garnet and as an abundant phase (~3-5 modal %) in the matrix. The second population is opaque in transmitted light, occurs exclusively as a matrix phase, and has the stoichiometric formula (Zn0-0.12Fe0.85-0.98Mn0.01-0.02)TiO3. The paragenesis of zinc-bearing ilmenite solid-solution in metapelitic rocks is problematic. -from Authors
