Deep crustal relamination drives post-collisional magmatism

Nature Geoscience, Published online: 07 May 2026; doi:10.1038/s41561-026-01977-4 An integrated thermomechanical modelling and experimental approach revealed that post-collisional, calc-alkaline magmas result from the mechanical hybridization of relaminated continental crust and mantle peridotite. This interaction has contributed to crustal evolution since the Archaean.
