Cluster of water molecules in garnet of eclogite: an evidence of the existence of fluid during ultra-high pressure metamorphic process
榴辉岩石榴石中的水分子团：超高压变质过程中流体的证据

Clusters of water molecules within garnet, which comes from foliated eclogite of ultra-high pressuremetamorphic belt from the Dabie Mountains, is identified by transmission electron microscopy. This indicates that garnet, as a carrier of fluids, is able to bring water into the mantle while continental rocks were subducted. And clusters of water molecules within garnet are very important evidence of the existence of fluid during ultra-high pressure metamorphic process.
