Stability of (Mg,Fe)₁₄Si₅O₂₄ AT 17 GP_a and 1800°C and its partitioning behavior of transition elements

Research output: Contribution to journal › Article › peer-review

Abstract

Stability of an anhydrous analogue of phase B (AnhB) was investigated at 17 GPa and 1800°C using an MA8 type apparatus. Fe/(Mg+Fe) ratio in AnhB is restricted to within ∼0.1. The divalent transition elements such as Ni and Co are preferentially accommodated in AnhB than in modified spinel (β).
