【摘要】 通过透射电镜,我们在大别山榴辉岩的石榴石中识别出水分子团。这证明了在大陆地壳岩石俯冲的过程中,石榴石作为水的载体是可以将水携带到地慢深处。而石榴石中的水分子团为超高压变质过程中有流体存在提供了有力的证据。更多还原

【Abstract】 Clusters of water molecules within garnet,which comes from foliated eclogite of ultra-high pressure metamorphic 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.更多还原
