Genesis and evolution of kimberlites
Kimberlites are volcanic rocks enriched in CO2 and H2O and derive from the deepest-
sourced melts (up to 300 km) that reach Earth's surface. The mantle processes that generate …

Geodynamics of kimberlites on a cooling Earth: Clues to plate tectonic evolution and deep volatile cycles
Kimberlite magmatism has occurred in cratonic regions on every continent. The global age
distribution suggests that this form of mantle melting has been more prominent after 1.2 Ga …

A global-scale plate reorganization event at 105− 100 Ma
A major plate reorganization is postulated to have occurred at approximately 100Ma.
However, this reorganization has received limited attention, despite being associated with …

Tectonic setting of kimberlites
Kimberlites can be viewed as time capsules in a global plate tectonic framework. Their
distribution illustrates clustering in time and space. Kimberlite ages span the assembly and …

Constraining South Atlantic growth with seafloor spreading data
L Pérez‐Díaz, G Eagles - Tectonics, 2014 - Wiley Online Library
Abstract Recent models of South Atlantic opening history focus on early plate divergence by
incorporating intracontinental deformation, which is poorly constrained. Aiming to avoid the …
