Generation of Earth's early continents from a relatively cool Archean mantle
Several lines of evidence suggest that the Archean (4.0–2.5 Ga) mantle was hotter than
today's potential temperature (TP) of 1350° C. However, the magnitude of such difference is …

Insights into the compositional evolution of crustal magmatic systems from coupled petrological-geodynamical models
The evolution of crustal magmatic systems is incompletely understood, as most studies are
limited either by their temporal or spatial resolution. Exposed plutonic rocks represent the …
