Strongly basal contacts are always associated with intense brecciation presence large amounts felsic pegmatite, suggesting multistage emplacement succession. Thermal modeling demonstrates multiple episodes magma influx required allow significant partial melting basement. Moreover, interaction between basement led local addition water and, potentially, carbon dioxide magma, resulting small-scale dissolution cumulus phases reduction viscosity interstitial melt. increased porosity mush vicinity lower intrusion contact, promoted preferential liquid accumulation at base, while decrease facilitated gravitational settling droplets. These factors an efficient liquid, especially center complex, where permeability maintained longest due slower cooling relative more peripheral parts.
