    Melt migration from a mantle source to eventual eruption may involve a variety of processes operating over a range of scales. For instance, melt ascent begins with grain-scale interactions, which, for larger fluxes may be described by permeable flow. Field evidence demonstrates that melt eventually coalesces to forms vein or dyke networks, which may rapidly ascend and be erupted, or be emplaced at depth, where they may feed into crustal magma chambers. A variety of mathematical formulations exist to describe these processes at different scales, and this contribution draws these diverse approaches together to form a framework for quantifying magma ascent from source to surface.
