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

Deep mantle plumes and an increasing Earth radius

Geodesy and Geodynamics, 2019
Recent space geodetic and gravimetric studies have given indications that the Earth's radius is increasing at 0.1–0.4 mm yr−1 at present. Seismic studies have also shown that earthquakes alone could be causing the radius to increase at 0.011–0.06 mm yr−1.

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).

Modeling Anisotropic Signature of Slab‐Induced Mantle Plumes From Thermochemical Piles in the Lowermost Mantle

Geophysical Research Letters
Seismic anisotropy, observed in the lowermost mantle near Large Low‐Shear‐Velocity Provinces (LLSVPs), is likely caused by strong deformation from mantle flow interacting with these regions and/or plume formation.

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.

Noble gases confirm plume-related mantle degassing beneath Southern Africa

Nature Communications, 2019
Southern Africa is characterised by unusually elevated topography and abnormal heat flow. This can be explained by thermal perturbation of the mantle, but the origin of this is unclear.

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.

Influence of the Hainan Plume on the Deep Thermal Structure and Shallow Geothermal Field of Southeastern Coastal China

Journal of Marine Science and Engineering
Thermal anomalies within the lithosphere are an important manifestation of mantle plume–lithosphere interaction. Early studies primarily concentrated on the presence of the Hainan plume and its surface responses, with comparatively little research ...
