DOI: 10.1016/j.precamres.2020.105654
Abstract: Abstract The Rustenburg Layered Suite (RLS) of the Bushveld Complex, the largest ultramafic–mafic-layered intrusion on Earth, is associated with satellite intrusions and marginal sills with which it shares a common parental heritage (i.e. the B1,… read more here.

DOI: 10.1073/pnas.2210258119
Abstract: Significance The modern Earth is geologically dynamic. Convection in its rocky mantle drives plate tectonics that reshapes its surface, and currents inside its metallic core generate a strong planetary magnetic field. However, it is uncertain… read more here.

DOI: 10.1126/sciadv.aaz8670
Abstract: Archean basalts from the Pilbara Craton, Western Australia record the oldest long-range lithospheric motion identified to date. The mode and rates of tectonic processes and lithospheric growth during the Archean [4.0 to 2.5 billion years… read more here.
