In plate subduction zones, various interplate earthquakes and volcanic activities are observed. These activities in the subduction zones are dependent on the nature of the subduction inputs, such as the surface topography, materials, temperatures, rigidity, and the degree of hydration. In addition, plate subduction plays a unique role in the global material circulation by transporting Earth's surface materials into the deep interior.
The nature of the oceanic plate as a subduction zone input, which is a boundary condition for these various tectonic activities and evolution of the Earth, is determined through various processes including the plate formation at the mid-oceanic ridge, the plate evolution at the deep sea basin, alteration due to plate-bending related faulting near the trench, and the post-spreading volcanic activities like the petit-spot.
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.
