Mantle plumes and their role in Earth processes
The existence of mantle plumes was first proposed in the 1970s to explain intra-plate,
hotspot volcanism, yet owing to difficulties in resolving mantle upwellings with geophysical …

Deconstructing plate tectonic reconstructions
The evolving mosaic of tectonic plates across the surface of the Earth sets boundary
conditions for the evolution of biotic and abiotic processes and helps shape the dynamics of …

A tectonic-rules-based mantle reference frame since 1 billion years ago–implications for supercontinent cycles and plate–mantle system evolution
Understanding the long-term evolution of Earth's plate–mantle system is reliant on absolute
plate motion models in a mantle reference frame, but such models are both difficult to …

Plate tectonics and mantle controls on plume dynamics
Mantle plumes provide valuable information about whole-mantle convection: they originate
at the core-mantle boundary, cross Earth's mantle and interact with the lithosphere. For …

Long-term evolution of a plume-induced subduction in the Neotethys realm
The head of a mantle plume can weaken the oceanic lithosphere through the combined
action of its buoyancy forces and excess temperature, which eventually induces intra …

Zircon U‐Pb geochronology constrains continental expression of Great Meteor Hotspot magmatism
Abstract The New England‐Québec Igneous Province is considered to be a continental
expression of Great Meteor Hotspot magmatism, though other geodynamic scenarios have …

Plume-induced flood basalts on Hesperian Mars: An investigation of Hesperia Planum
A Broquet, JC Andrews-Hanna - Icarus, 2023 - Elsevier
Hesperian Mars was characterized by a unique style of geodynamic activity that left crucial
volcano-tectonic records in the form of extensive flood lavas covered by wrinkle ridges. Yet …

New geochemical and Sr-Nd-Pb isotope evidence for FOZO and Azores plume components in the sources of DSDP Holes 559 and 561 MORBs
Enriched mid-ocean ridge basalts (E-MORBs) near hotspots are commonly ascribed to be
products of mantle plume-ridge interaction, but the genesis of E-MORBs far from hotspots …
