The evolution of the Galápagos mantle plume [PDF]
Science Advances, 2023 The lavas associated with mantle plumes may sample domains throughout Earth’s mantle and probe its dynamics. However, plume studies are often only able to take snapshots in time, usually of the most recent plume activity, leaving the chemical and geodynamic evolution of major convective upwellings in Earth’s mantle poorly constrained.

A subduction and mantle plume origin for Samoan volcanism [PDF]
Scientific Reports, 2018 The origin of Samoan volcanism in the southwest Pacific remains enigmatic. Whether mantle melting is solely caused by a mantle plume is questionable because some volcanism, here referred to as non-hotspot volcanism, defies the plume model and its linear ...

Geophysical Monograph Series, Page 1-26., 2021 Exploring the links between Large Igneous Provinces and dramatic environmental impact
An emerging consensus suggests that Large Igneous Provinces (LIPs) and Silicic LIPs (SLIPs) are a significant driver of dramatic global environmental and biological changes, including mass extinctions.

Seismic evidence of the Hainan mantle plume by receiver function analysis in southern China
Geophysical Research Letters, 2016 The Lei‐Qiong region is the largest igneous province in southern China and may be a surface expression of a mantle plume beneath the region (the Hainan mantle plume).

Synchronous motion of the Easter mantle plume and the East Pacific Rise [PDF]
Nature CommunicationsThe Easter mantle plume has produced one of the longest hotspot tracks in the Pacific Ocean. While previous studies have focused on the eastern side extending across the Nazca Plate, we use 40Ar/39Ar isotopic and geochemical data to investigate the less ...

Research progress of mantle plume
地震科学进展, 2021 Since the mantle plume hypothesis was proposed，it has been controversial in academia，and there is no unified answer to its existence. In this paper，the origin of the mantle plume is elaborated in detail.

Mantle Plumes and Mantle Sources [PDF]
Science, 1992 Basalts from many ocean islands define elongate arrays in Sr-Nd-Pb isotopic space; these likely reflect the dominance of binary mixing of mantle sources in intraplate volcanism. S. R. Hart et al. (1) observe that when these arrays are projected onto a ternary diagram bounded by mantle end-members DMM [depleted mid-ocean ridge basalt (MORB) mantle ...
