Sizes and Ages of Seamounts Using Remote Sensing: Implications for Intraplate Volcanism
, 1997 Satellite altimetry was used to identify and characterize Pacific intraplate seamounts. The gravimetric amplitudes of seamounts appear to be related to the age difference between the sea floor and seamounts; by inverting this relation, pseudo ages can be

Geochemistry, Geophysics, Geosystems, 2020 What drives the formation of basaltic melts beneath intraplate volcanoes not associated with extensive thermal anomalies or lithospheric extension? Detailed constraints on the melting conditions and source region are imperative to resolve this question ...

Melt Production and Volatile Release From Thermochemical Mantle Plumes
Geophysical Research Letters, Volume 53, Issue 20, 28 October 2026.Abstract Mantle plumes are thought to generate Large Igneous Provinces (LIPs), the largest outpourings of lava in the geologic record, which are associated with long‐lasting climatic warming events and mass extinctions. However, the controls on mantle degassing by plumes remain poorly constrained.

Geophysical Research Letters, Volume 53, Issue 19, 16 October 2026.Abstract Ground deformation of dormant volcanoes provides critical insights into subsurface processes and potential hazards. Here we present Sentinel‐1 Interferometric Synthetic Aperture Radar (InSAR) time series (2015–2020) for Changbaishan volcano, the largest intraplate volcanic system in East Asia. We detect persistent subsidence of up to 3.5 mm/yr

Volcanology of tuff rings at Kellyville, Onewhero and Bombay, South Auckland Volcanic Field [PDF]
, 2011 The South Auckland volcanic field hosts 82 volcanic centres over an area of approximately 300 km2 in the Pukekohe, Bombay, Tuakau, Pukekawa and Onewhero regions. The intraplate, monogenetic basaltic volcanic field was active between 1.59 and 0.51 Ma, and

Physical characteristics of kimberlite and basaltic intraplate volcanism and implications of a biased kimberlite record [PDF]
, 2013 We assess bias in the record of kimberlite volcanism by using newly acquired size data on more than 900 kimberlite bodies from 12 kimberlite fields eroded to depths of between 0 m and >1200 m, and by a comparison with intraplate monogenetic basaltic ...

, 2022 The extensive and well-preserved lava fields, “harrats” in Arabic, of western Saudi Arabia stretch for 3000 km south to north and cover an area of more than 120.000 km2 in total. The alkalic volcanism initiated at ca.

Intraplate volcanism off South Greenland: Caused by glacial rebound?
, 2012 Plate tectonic mechanisms explain most of the dominant types of volcanism. Intraplate volcanism has been attributed to hot spots associated with mantle plumes, though alternative explanations have been proposed for settings not fed by plumes.

Geodynamic Significance of Intraplate Basaltic Magmatism From the Western Mediterranean Region
Geochemistry, Geophysics, Geosystems, Volume 27, Issue 10, October 2026.Abstract Dynamic topography changes as mantle convection evolves, making its past surface expression difficult to reconstruct. Widespread Neogene‐Quaternary intraplate basaltic magmatism across the Western Mediterranean Region allows us to test whether dated basalts preserve the mantle thermal structure responsible for regional dynamic support.
