Transactions of the Karelian Research Centre of the Russian Academy of Sciences, 2018 There is an opinion that Paleoproterozoic magmatism in the Karelian craton of the Baltic Shield is linked solely with the influence of mantle plumes.

Geophysical Research Letters, Volume 53, Issue 3, 16 February 2026.Abstract The origin of a binary‐mixing of DM and EM1 sources for the Cenozoic intraplate volcanism in eastern Northeast China is yet unclear. Seismic attenuation imaging is a tool that can shed light on this question. Here we present the first map of teleseismic P‐wave attenuation across Northeast China.

Variations in Hawaiian Plume Flux Controlled by Ancient Mantle Depletion
AGU AdvancesMantle plumes—upwellings of buoyant rock in Earth's mantle—feed hotspot volcanoes such as Hawai‘i. The size of volcanoes along the Hawai‘i–Emperor chain, and thus the magma flux of the Hawaiian plume, has varied over the past 85 million years.

Seismic visualization of plumes and super-deep fluids in mantle under Ukraine
Геофизический журнал, 2017 According to the Taylor approximation of the three-dimensional P-velocity model of the mantle under Eurasia, a seismic visualization of the manifestation of mantle plumes and super-deep fluid processes was carried out.

Lithospheric Delamination Below the North American Midcontinent Ceased Subsidence in Cratonic Basins
AGU Advances, Volume 7, Issue 1, February 2026.Abstract Cratonic lithospheres carry a long history of tectonic modifications that result in heterogeneous structures, as revealed by an increasing number of geophysical observations. The existence of cratonic basins indicates protracted periods of tectonic modification, causing subsidence within global continental interiors.

High-MgO lavas associated to CFB as indicators of plume-related thermochemical effects: the case of ultra-titaniferous picrite-basalt from the Northern Ethiopian-Yemeni plateau [PDF]
A comprehensive petrological and geochemical dataset is reported in order to define the thermo-compositional characteristics of Ti (Fe)-enriched picrite-basalt lavas (HT2, TiO2 3-7 wt%), erupted close to the axial zone of the inferred Afar mantle plume ...

Insights Into Mantle Plume Geochemistry From Machine Learning
Geochemistry, Geophysics, GeosystemsOceanic island basalts are the products of mantle plume melting and their chemistry provides insights into the Earth's deep interior. We report a statistical and machine learning study of 8 radiogenic isotopes and 19 incompatible trace element ratios in ...

Impact‐Generated Mixing, Melting and Vaporization of the Early Earth's Crust
Earth and Space Science, Volume 13, Issue 2, February 2026.Abstract Earth's primary accretion was followed by a protracted flux of interplanetary collisions by leftover planetesimals. The effects of the largest collisions—with bodies possibly exceeding 1,000 km diameter—would have been devastating for terrestrial near‐surface environments.

Plume‐Driven Subduction Termination in 3‐D Mantle Convection Models
Geochemistry, Geophysics, GeosystemsThe effect of mantle plumes is secondary to that of subducting slabs for modern plate tectonics when considering plate driving forces. However, the impact of plumes on tectonics and planetary surface evolution may nonetheless have been significant.
