The study shows that intense fracturing within the magmatic body, induced by the shearing of the magma during emplacement, represent high-permeability zones that channel subsurface fluid migrations. Our study highlights the high relevance of accounting for fractured subsurface magmatic intrusions in basin models, but also on geothermal energy exploration.
