Mantle plumes are oxidised

Earth and Planetary Science Letters, 2019
Abstract From oxic atmosphere to metallic core, the Earth's components are broadly stratified with respect to oxygen fugacity. A simple picture of reducing oxygen fugacity with depth may be disrupted by the accumulation of oxidised crustal material in the deep lower mantle, entrained there as a result of subduction. While hotspot volcanoes are fed by

Lithosphere‐Asthenosphere Interactions Across the Indo‐Burma Subduction Zone From Sp Receiver Functions

Geophysical Research Letters, Volume 53, Issue 11, 16 June 2026.
Abstract The Cenozoic convergence between the Indian and Asian plates has driven large‐scale mantle convection that interacts with both plates. Understanding this convergence benefits from clear imaging of the lithosphere‐asthenosphere boundary (LAB).

Asymmetric three-dimensional topography over mantle plumes

, 2014
International audienceThe role of mantle–lithosphere interactions in shaping surface topography has long been debated1–3. In general3,4, it is supposed that mantle plumes and vertical mantle flows result in axisymmetric, long-wavelength topography, which

Insights Into Mantle Plume Geochemistry From Machine Learning

Geochemistry, Geophysics, Geosystems
Oceanic 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 ...

Absent Grief, Manic Undoing, and the Transgenerational Transmission of Unclaimed Experience: A Cryptic Reading of Murakami's Tony Takitani

International Journal of Applied Psychoanalytic Studies, Volume 23, Issue 2, June 2026.
ABSTRACT Trauma and loss constitute recurring themes in both Murakami's fictional and non‐fictional writing. In the short story Tony Takitani, Murakami portrays a father and son confronting trauma and loss in the aftermath of the Second World War and the nuclear devastation of Japan.

Crystallization temperatures of tholeiite parental liquids: Implications for the existence of thermally driven mantle plumes

, 2016
To compare magmatic crystallization temperatures between ocean island basalt (OIB) proposed to be plume-related and normal mid-ocean ridge basalt (MORB) parental liquids, we have examined and compared in detail three representative magmatic suites from ...

Plume‐Driven Subduction Termination in 3‐D Mantle Convection Models

Geochemistry, Geophysics, Geosystems
The 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.

Loess Studies in Aotearoa New Zealand

New Zealand Journal of Geology and Geophysics, Volume 69, Issue 2, June 2026.
Loess in Aotearoa New Zealand (ANZ) has been studied since its first documented recognition (on Banks Peninsula) in 1878 by Julius von Haast. A decade later, John Hardcastle revealed that southern ANZ loess was both glacial in origin and contained signals of past climates.

Hotspots, Mantle Plumes and Core Heat Loss

, 2002
International audienceThe heat flux at the core-mantle boundary (CMB) is a key parameter for core dynamics since it controls its cooling. However, it is poorly known and estimates range from 2 TW to 10 TW.

A Synoptic View of Mantle Plume Shapes Enabled by Virtual Reality

Geochemistry, Geophysics, Geosystems
The shapes of mantle plumes are sensitive to mantle viscosity, density structure, and flow patterns. Increasingly, global tomographic models reveal broad plume conduits in the lower mantle and highly tilting conduits in the mid and upper mantle. Previous
