| Scope (Session Description) |
Oceanic plate-subduction processes drive phenomena such as magma generation and fault formation, triggering volcanic and earthquake activity at subduction zones. Scales and distributions of such subduction zone-phenomena are controlled by physicochemical properties of subducting oceanic plates. In addition, oceanic plate-subduction processes transport surface materials such as water and carbon into the deep interior of Earth, playing an important role in global geochemical cycles. Physicochemical properties of oceanic plates as "subduction inputs" reflect their evolutionary histories from plate formation at mid-ocean ridges until subduction at trenches. We welcome contributions from a broad range of earth science (geophysics, geochemistry, geology, petrology, drilling science, and so on) discussing topics related to the nature of the subduction inputs and its spatial variations. This session is supported by the focus group of hard rock drilling science. |
