Abstract

A high-titanium containing garnet, SiO₂(40.6), TiO₂(6.3), Al₂O₃(18.8), MgO(14.3), CaO(20.21), (wt%) has been synthesized at 10 GPa and 1500°C. Unit cell parameter of this synthetic garnet is determined to be 11.812 Å by micro-focused X-ray diffractmetry and this value is intermediate between those of pyrope and grossular. These results indicate that pyrope-grossular garnet potentially can accommodate TiO₂ up to 6.3 wt% at the high of 10 GPa.
