However, the mantle would have been sufficiently cool after ~1 Ga for water to be effectively transported to the MTZ18, and the MTZ would have become locally hydrated because of dehydration/decarbonation of the stagnant slabs48. The mantle plumes of the hydrous Siberian Traps magmatism could ...
Zheng and Zhao (2020) insightfully point out that plate tectonics involves two kinematic systems, horizontal as above, and vertical, including the sinking of subducting slabs into the mantle, and the return flow of material to upwell beneath spreading ridges, continental rifts, and plumes (Maruyama...
The highly refractory compositions of diamond inclusion minerals could imply preferential diamond growth in the more reducing parts of the cratonic root, depleted by ultra-hot melting in response to heat plumes from a deeper former boundary layer that vanished at the end of the Archaean13. This ...
The Choiyoi Magmatic Province represents a major episode of silicic magmatism in southwestern Pangea in the mid-Permian-Triassic, the origin of which remains intensely debated. Here, we integrate plate-kinematic reconstructions and the lower mantle slab

The variability of these ratios in oceanic plateau basalts is interpreted in terms of recycling variable quantities of oceanic crust processed through a subduction zone (high Nb/U, Nb/Th), and complementary arc crust (low Nb/U, Nb/Th) into the source of the plumes. In the Wawa and ...
54), Kenyan18 and Afar20 mantle plumes, respectively. Note that V and C have the approximately the same 206Pb/204Pb values. The range of ‘classic' HIMU islands is defined by the St. Helena and the Cook–Australs; data from the GEOROC database (http://georoc.mpch-mainz.gwdg.de/)....
