island arc

Show Summary Details

Quick Reference

An arcuate island chain, mostly of volcanic origin, formed when oceanic crust plunges into the mantle where it undergoes subduction. The magma thus formed creates a chain of submarine volcanoes—eventual islands; see Jicha et al. (2006) Geology 34, 8 on magma flow in the Aleutian Island arc. See also Takahashi et al. (2007) Geology 35, 3.
