Role of Large Igneous Provinces in continental break-up varying from “Shirker” to “Producer”

A Koptev, S Cloetingh - Communications Earth & Environment, 2024 - nature.com
Traditionally, the emplacement of the Large Igneous Provinces (LIPs) is considered to have
caused continental break-up. However, this does not always seem to be the case, as …

Formation of continental microplates through rift linkage: Numerical modeling and its application to the Flemish Cap and Sao Paulo Plateau

D Neuharth, S Brune, A Glerum… - Geochemistry …, 2021 - Wiley Online Library
Continental microplates are enigmatic plate boundary features, which can occur in
extensional and compressional regimes. Here we focus on microplate formation and their …

Chemical geodynamics insights from a machine learning approach

A Stracke, M Willig, F Genske… - Geochemistry …, 2022 - Wiley Online Library
The radiogenic isotope heterogeneity of oceanic basalts is often assessed using 2D isotope
ratio diagrams. But because the underlying data are at least six dimensional (87Sr/86Sr …

On the origin of the Canary Islands: Insights from mantle convection modelling

AM Negredo, J van Hunen… - Earth and Planetary …, 2022 - Elsevier
Abstract The Canary Islands hotspot consists of seven volcanic islands, mainly of Neogene
age, rooted on oceanic Jurassic lithosphere. Its complex structure and geodynamic setting …

Linking intraplate volcanism to lithospheric structure and asthenospheric flow

T Duvernay, DR Davies, CR Mathews… - Geochemistry …, 2021 - Wiley Online Library
Several of Earth's intraplate volcanic provinces are hard to reconcile with the mantle plume
hypothesis. Instead, they exhibit characteristics that are more compatible with shallower …

Widespread volcanism in the Greenland–North Atlantic region explained by the Iceland plume

B Steinberger, E Bredow, S Lebedev, A Schaeffer… - Nature …, 2019 - nature.com
In the classical concept, a hotspot track is a line of volcanics formed as a plate moves over a
stationary mantle plume. Defying this concept, intraplate volcanism in Greenland and the …

Longevity of small-scale ('baby') plumes and their role in lithospheric break-up

A Koptev, S Cloetingh, TA Ehlers - Geophysical Journal …, 2021 - academic.oup.com
Controversy between advocates of 'active'(plume-activated) versus 'passive'(driven by
external tectonic stresses) modes of continental rifting and break-up has persisted for …

Continental magmatism: The surface manifestation of dynamic interactions between cratonic lithosphere, mantle plumes and edge‐driven convection

T Duvernay, DR Davies, CR Mathews… - Geochemistry …, 2022 - Wiley Online Library
Several of Earth's intra‐plate volcanic provinces lie on or adjacent to continental lithosphere.
Although many are believed to mark the surface expression of mantle plumes, our limited …

Observational estimates of dynamic topography through space and time

M Hoggard, J Austermann, C Randel… - Mantle convection …, 2021 - Wiley Online Library
Earth's mantle undergoes convection on million‐year timescales as heat is transferred from
depth to the surface. While this flow has long been linked to the large‐scale horizontal forces …
