Building archean cratonic roots
Frontiers in Earth Science, 2022 Geophysical, geochemical, and geological investigations have attributed the stable behaviour of Earth’s continents to the presence of their Archean cratonic roots.

Geophysical Monograph Series, Page 1-26., 2021 Exploring the links between Large Igneous Provinces and dramatic environmental impact
An emerging consensus suggests that Large Igneous Provinces (LIPs) and Silicic LIPs (SLIPs) are a significant driver of dramatic global environmental and biological changes, including mass extinctions.

Intraplate deformation of Gondwana terranes and implications for the Wilson Cycle [PDF]
Scientific ReportsThe Wilson Cycle, a cornerstone of plate tectonic theory, describes the cyclical evolution of ocean basins from rifting and spreading to closure via subduction and continental collision and assembly.

Oxidation of Archean upper mantle caused by crustal recycling [PDF]
Nature Communications, 2022 The basalt V-Ti redox proxy indicates that both of the Archean ambient and modified mantle exhibit a ~1.0 log unit increase in their evolution for most cratons, possibly derived by widespread crustal recycling.

Channelized metasomatism in Archean cratonic roots as a mechanism of lithospheric refertilization [PDF]
Nature CommunicationsArchean cratons represent stable continental domains which form the nuclei of the Earth’s continents due to their thick ( >200 km), mechanically resistant keels. Cratons and their stable roots form through melt and fluid depletion processes.

Gravity and magnetism of southern Africa in relation to Craton structures and belts [PDF]
HeliyonThe general tectonic structural architecture of southern Africa is an ensemble comprised of Kalahari Craton, a vast range of mosaics of the best-preserved geological Belts, and exposed crustal blocks.

The statherian taphrogenesis of the South American Platform [PDF]
Brazilian Journal of Geology, 2022 Records of Statherian intracontinental ruptural tectonics, magmatism and sedimentation events are recognized all over the South American Platform as an immediate tectonic response to the formation of a large continental domain during Rhyacian-Orosirian ...

Geochemistry, Geophysics, Geosystems, 2021 Africa's Cenozoic tectonism is often attributed to mantle plumes, particularly below East Africa, but their morphology, number, location, and impact on the African lithosphere are debated.

The Relationship Between Kimberlitic Magmatism and Electrical Conductivity Anomalies in the Mantle
Geophysical Research Letters, 2022 Kimberlites are igneous rocks whose formation remains enigmatic due to their severely altered nature, highly variable compositions and rapid ascent through the lithosphere.
