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 ...

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.

Gold mineralization and metallogenesis associated with mantle dynamics in East China
Frontiers 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 ...

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 ...

Plume–ridge interactions: ridgeward versus plate-drag plume flow [PDF]
Solid Earth, 2023 The analysis of mid-ocean ridges and hotspots that are sourced by deep-rooted mantle plumes allows us to get a glimpse of mantle structure and dynamics.

Geochemistry, Geophysics, Geosystems, 2021 The flow of high‐temperature and compositionally enriched material between mantle plumes and nearby spreading centers influences up to 30% of the global mid‐ocean ridge system and represents a significant, but currently unconstrained, flux of volatiles ...

Nature Communications, 2023 Discovering ancient mantle plumes is challenging. By combining electrical conductivity with mineral physics modelling, this work finds a remnant of an ancient plume trapped in the mantle transition zone and sheds new light on mantle plume physics.

Robust Seismic Images of the Hawaiian Plume
Geophysical Research Letters, 2022 To image the Hawaiian plume and the plume‐lithosphere interaction, we determine a robust 3‐D shear‐wave velocity (Vs) model of the upper mantle and the mantle transition zone (MTZ) beneath Hawaii by jointly inverting teleseismic S‐wave arrival times ...
