Global distribution of the HIMU end member: Formation through Archean plume-lid tectonics
Oceanic basalts reflect the heterogeneities in the earth's mantle, which can be explained by
five mantle end members. The HIMU end member, characterized by high time-integrated μ …

Waveform tomography reveals channeled flow at the base of the oceanic asthenosphere
Understanding the relationship between different scales of convection that drive plate
motions and hotspot volcanism still eludes geophysicists. Using full-waveform seismic …

Chemical geodynamics insights from a machine learning approach
The radiogenic isotope heterogeneity of oceanic basalts is often assessed using 2D isotope
ratio diagrams. But because the underlying data are at least six dimensional (87Sr/86Sr …

Evidence for compositionally distinct upper mantle plumelets since the early history of the Tristan-Gough hotspot
Recent studies indicate that mantle plumes, which transfer material and heat from the earth's
interior to its surface, represent multifaceted upwellings. The Tristan-Gough hotspot track …
