摘　　要：介绍了近年来金刚石包裹体中流体研究结果，特别是分子氢和羟基的发现。基于地幔中氢的发现，论证了氢在地球内部的赋存形式。地核和地幔中有氢化物存在得到高压低温实验、地球物理和天文物理测定的支持。从而提出，氢是地幔羽中的原始热物质。核幔边界或地幔中氢化物释放出的氢，发生化学反应，形成地幔流体，推动地球演化。地幔羽应称为氢羽。Recent studies of fluids in the diamonds, particularly the discovery of molecular hydrogen and hydroxy are presented in the paper. The hydrogen discovered in the mantle demonstrates its existential form in the earth interior. The existance of hydride in earth core and mantle is supported by experiments at high pressure and low temperature, geophysical and astrophysical measures. Then it is proposed that hydrogen is primary hot material in the mantle plumes. The hydrogen released from hydride at the core mantle boundary or mantle had been reacting chemically, yielding mantle fluids to promote earth evolution. The mantle plume is really the hydrogen plume.
