Subduction zones special issue in Solid Earth

Editors: Susanne Buiter, Francesca Funiciello, Jeroen van Hunen

Solid Earth is an open access Earth Sciences journal from the European Geosciences Union.

Subduction drives plate tectonics, forms continents, and transports surface material to the deep Earth. Therefore, it is arguably the most important geodynamical and geochemical phenomenon on Earth. In addition, the direct association with devastating earthquakes and active volcanism signifies a need for deep understanding of all aspects of this process. Recent studies of subduction processes have been able to build on results of decades of research and we consider it timely, therefore, to bring together studies of subduction zone dynamics at all scales from the surface to the lower mantle. For this special issue we invite contributions from a wide range of disciplines, including, and certainly not limited to, geodynamics, modelling, geochemistry, mineralogy, petrology and seismology. Topics could include:

• the initiation of subduction;
• the role of phase transitions and the migration of fluids and melts;
• controlling parameters for slab dip angle;
• the role of near-surface processes in controlling slab dynamics;
• the fate of subducted crust, sediments and volatiles;
• the influence of the mantle wedge and the back-arc on slab dynamics;
• slab break-off;
• subduction of seamounts, LIPs and ridges;
• continental collision;
• links between subduction and the development of mineral deposits;
• imaging of present-day subduction zones and surrounding mantle flow.
