Plume‐tree structure induced by low‐viscosity layers in the upper mantle

H Liu, W Leng - Geophysical Research Letters, 2020 - Wiley Online Library
Previous seismological results and geodynamic modeling showed that mantle plumes have
thin tails. However, the latest geophysical observations reveal the presence of broad and …
