Book Chapter
A chapter from the book "Oceans" is presented. It discusses the current of the Earth's mantle that makes ocean floors expand or shrink. The process involves the creation of deep ocean trenches, long chains of volcanic islands known as island arcs, and mountain ranges. It includes discussion about subduction zones which are the destructive plate margins where edges sink back into the mantle. Regions close to these zones are prone to earthquakes.

    Oceanic arcs and deep-sea trenches are the surface expressions of oceanic plates sub-ducting into the Earth's mantle. We use a new numerical technique for simulating the dynamical evolution of the lithosphere-mantle interaction in order to assess the causes of arc curvature. We group the...

    Glass-bearing inclusions hosted by Cr-spinel in harzburgite xenoliths from Avacha are grouped based on homogenization temperatures and daughter minerals into high-T (1,200°C; opx + cpx), intermediate (900-1,100°C; cpx ± amph), and low-T (900°C; amph) and are commonly accompanied by...

    In subduction zones, melting and dehydration of the subducted slab introduce material into the mantle wedge and modify its chemical and isotopic composition. As a consequence, island arc lavas differ significantly from mid-ocean ridge basalts and ocean island basalts. In some arcs, the...

    Subduction zone magmas are characterized by high concentrations of pre-eruptive H2O, presumably as a result of an H2O flux originating from the dehydrating, subducting slab. The extent of mantle melting increases as a function of increasing water content beneath back-arc basins and is predicted...
