    Sediment Recycling at Convergent Margins: Constraints from the Cosmogenic Isotope 10Be

    The question of whether sediments are subducted at convergent margins and subsequently incorporated in arc magmas has long been controversial. The cosmogenic isotope 10Be (T1/2 = 1.5 million years) suggests that ...

    Geophysical Constraints on Recycling of Oceanic Lithosphere

    The path of an oceanic slab as it subducts beneath a continent or ocean is generally illuminated by a plane of earthquakes. In most subduction zones the earthquake activity is probably confined to the upper te...

    Magma Generation in Subduction Zones

    There are two general classes of models for magma generation in subduction zones; melting of the subducted slab, or magma derivation from the asthenosphere wedge overlying the subducted slab. Lack of knowledge...
