From migmatites to granitoids

open access: yes
Melting processes in the continental crust are responsible for crust formation and recycling, and play an important role in heat transport. A better understanding of these processes can shed light on crustal differentiation and continental growth throughout the Earth’s history. This thesis focuses on three major key aspects of the link between the melt
