上地幔岩石是基性、超基性及某些其他成分岩浆的来源。岩浆熔体的熔融及其由上地幔运移到地壳中,这在漫长的地球演化期间是一长期过程。毫无疑问,熔体的熔融并从上地幔岩石中分离出来,不可能在保存下来的残留物的成分中没有反映:地幔物质熔融和分离得越
Upper mantle rocks are the source of basic, ultramafic and some other magmatic components. The melting of the magma melt and its migration from the upper mantle into the crust is a long-term process during the long Earth’s evolution. There is no doubt that the melting of the melt and its separation from the upper mantle rock can not be reflected in the composition of the retained residue: the more the mantle material melts and separates
