The evolution of the Galápagos mantle plume. [PDF]

open access: yesSci Adv, 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 Mantle Plume Beneath South China Revealed by Electrical Conductivity Obtained from Three-Dimensional Inversion of Geomagnetic Data. [PDF]

open access: yesSensors (Basel), 2023
A three-dimensional electrical conductivity model of the mantle beneath South China is presented using the geomagnetic depth sounding method in this paper.

A subduction and mantle plume origin for Samoan volcanism. [PDF]

open access: yesSci Rep, 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 ...

Seismic evidence of the Hainan mantle plume by receiver function analysis in southern China

open access: yesGeophysical 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]

open access: yesNat Commun
The 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

open access: yes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]

open access: yesScience, 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 ...

Gold mineralization and metallogenesis associated with mantle dynamics in East China

open access: yesFrontiers in Earth Science, 2022
East China can be divided into two parts: the North China Block (or North China Craton) (NCC) and the South China Block (SCB). The mechanism for the destruction of the NCC and the large-scale magmatic activity in the SCB during the Mesozoic is a major ...
