The Mg isotopic systematics of granitoids in continental arcs and implications for the role of chemical weathering in crust formation

Continental crust is too Si-rich and Mg-poor to derive directly from mantle melting, which generates basaltic rather than felsic magmas. Converting basalt to more felsic compositions requires a second step involving Mg loss, which is thought to be dominated by internal igneous differentiation. Howev...
