Abstract

Single crystals of Ca-bearing majorite have been synthesized at 18.2 GPa and 2050°C. This sample is the first silicate garnet to display ordering on both octahedral and dodecahedral sites - behavior that may increase the compositional flexibility of garnet, affect element partitioning at high pressure, and stabilize the garnet structure in the transition zone and upper portion of the lower mantle. The garnet is tetragonal, and like MgSiO₃ majorite, displays twinning by twofold rotation about [110]. -from Authors
