Title: Solubility of water in pyrope‐rich garnet at high pressures and temperature
Abstract: The water solubility in pyrope‐rich garnet was determined between pressures of 5–9 GPa and temperatures of 1373–1473 K under silica activity and oxygen fugacity similar to those expected in the Earth's upper mantle. We found that pyrope‐rich garnet has substantial water solubility up to ∼0.1 wt% under these conditions. In addition, the water content in garnet varied as a function of chemical conditions. In particular, the variation in water fugacity (and Mg#) caused a variation in water partitioning with olivine The substantial water solubility in pyrope‐rich garnet under deep upper mantle conditions might have significant influence on physical and transport properties.
