Well-documented Lu-Hf isotope data from the oceanic basalts show that,the starting area of magma melting for the MORBs derived from the DMM component would be in the the depth of garnet peridotite,i.e.at the depth of 80―90 km instead of less than 60 km,which is at the depth of spinel peridotite as proposed early.The HIMU component,which is characterized by its high rediogenic lead,is refered as a special mantle component differentiated at some time in geological history from the lower mantle.A correlation study of Hf-Nd isotope between the chondrite and oceanic basalts implies that no isolated primitive mantle might have remained.
