This theme addresses the physical shape and connectivity of magma networks at all scales, from the crust to the grain boundary and from the source to the volcano, including the plutonic-volcanic connection. We will discuss the rates of processes such as melting, melt extraction, magma motion, pluton accretion, eruption, as well as the mechanical and chemical drivers of them.
