无论是简单的全地幔对流模型或分层地幔对流模型，都不能完全解释全部观测事实。
Simple models, no matter whole mantle convection model, or layered mantle convection model, cannot explain all the observations.
地震学、地球动力学研究倾向于全地幔对流模型； 地球化学研究则支持分层地幔对流。
Seismological and geodynamical evidences supported whole mantle convection model, while geochemical ones supported layered convection model.
