Local high rates of convergence at the Hellenic subduction zone (35mm/yr) are associated with back-arc spreading
throughout Greece and western Turkey above the subducting Mediterranean oceanic crust.
Their protoliths were probably generated within back-arc spreading
center and metamorphosed in a nascent subduction zone at depth around 50 km.
systems; geological, biological, chemical, and physical interactions.
research community as the best place in the world to study the links between the geology, chemistry, and biology of a back-arc spreading
center and to understand the large- scale cycling of materials from the seafloor to the Earth's interior and back again," Fisher said.
When arcs are stretched they split, initially forming a rift (an elongate depression bounded by high-angle faults) and eventually a back-arc spreading
