From: Archean continental crust formed by magma hybridization and voluminous partial melting

Major-element compositions for melts produced along a thermal gradient of 75 °C/kbar. Colors represent the temperature range at which each melt fraction equilibrated and separated from the source. Dark and light gray regions represent the mean composition of natural Archean TTGs within ± 1σ and ± 2σ1, respectively.
