Coupled Mechanisms of Fluid Transport Across the Crust

by Beatriz Quintal 14 September 202111 May 2022

Magmatic fluid moves up in the ductile zone through porosity waves, accumulates in high-porosity lenses, and migrates across the brittle zone in a convection pattern involving also meteoric fluid.
