In the last thirties years great advances of the studies of mantle plumes have been made. Based on the depth of origin, the mantle plumes have been subdivided into three groups. These are deep plume, transition zone origin plume and uppermantle plume. In this paper the criteria used to diagnose deep plumes and transition zone origin plumes are induced. The distribution of these plumes around the Earth surface and their shape are described. In addition, the superplumes in lower mantle and ultra-low velocity zones in mostly lower mantle found by the investigation of seismic tomography give an important evidence for the origin of plumes.
Key words： Plume; Ultra-low velocity zones in lowermost mantle.; Superplume; Hotspot
