Аннотация

Intra-oceanic arcs (IOAs) form at Pacific-type convergent margins, in the upper “stable” plate, when the subducting plate submerges to the depths of melting, i.e., to ca. 50–100 km. A typical IOA system, such as Mariana-Bonin and the Philippines Sea, consists of subduction zone, fore-arc region with accretionary prism, frontal or active arc, marginal basin with spreading center, and, in some cases, one or more remnant arcs and inactive marginal basin. The IOAs are very important elements of Pacific-type convergent margins as they represent major sites of juvenile continental crust formation (e.g. [Clift et al., 2003; Stern, 2010; Maruyama et al., 2011]), but are also the most important sites of crust removal by sediment subduction and tectonic/ subduction erosion [Stern, Scholl, 2010].
