Crustal melting vs. fractionation of basaltic magmas: Part 1, granites and paradigms
Granitoids are a major component of the continental crust. They play a pivotal role in its
evolution, either by adding new material (continental growth), or by reworking older …

Collision vs. subduction-related magmatism: two contrasting ways of granite formation and implications for crustal growth
Earth's continental crust is dominantly made of buoyant, felsic igneous material (granitoids),
that was ultimately extracted from the mantle as a result of Earth's differentiation. Since felsic …
