Mantle plumes and their role in Earth processes
The existence of mantle plumes was first proposed in the 1970s to explain intra-plate,
hotspot volcanism, yet owing to difficulties in resolving mantle upwellings with geophysical …

Mantle plumes and entrainment: isotopic evidence
SR Hart, EH Hauri, LA Oschmann, JA Whitehead - Science, 1992 - science.org
Many oceanic island basalts show sublinear subparallel arrays in Sr-Nd-Pb isotopic space.
The depleted upper mantle is rarely a mixing end-member of these arrays, as would be …
