Abstract

Single-crystal X-ray diffraction data have been obtained for synthetic Fe-Mg silicate spinels. The measurements on γ-Mg2SiO4 synthesized at 20 GPa and 1400°C, compared with previous data on a specimen synthesized at 22 GPa and 1000°C, provide evidence that approximately 4% of Sitot enters octahedral coordination in the sample synthesized at higher temperature. Fe-bearing silicate spinels synthesized at lower pressures display no evidence for Fe-Si disorder. -Authors
