The deep magma transport system is a key in volcanic eruptions, geodynamics, and the evolution of the Earth. To understand the deep volcanic roots, we need to integrate studies from various approaches. For example, the geochemical properties of igneous rocks enable us to track the origin of magma and its evolutionary processes, including fractional crystallization, assimilation, and mixing. Experimental studies under the pressure and temperature conditions at the mantle wedge are essential for understanding realistic magma generation. High-resolution seismic or electrical resistivity imaging is also informative. The source process of deep long-period earthquakes, which are the only seismic events at the deep crust, is also a key. We welcome all studies related to understanding volcanic roots from a variety of approaches, including but not limited to the methods mentioned above, and look for activating discussions across multiple disciplines.
