The komatiite testimony to ancient mantle heterogeneity
Komatiites are crystallized samples of high-temperature, high-MgO lavas that were common
during the Archean, but became increasingly rarer in the Proterozoic and Phanerozoic …

Mechanisms of Archean crust formation inferred from high-precision HFSE systematics in TTGs
It has been proposed that Archean tonalitic–trondhjemitic–granodioritic magmas (TTGs)
formed by melting of mafic crust at high pressures. The residual mineralogy of the TTGs …
