Dear Colleagues-
We cordially invite you to submit an abstract to the session Elemental and Isotopic Fractionation in Subduction Zones – Consequences for Arc Evolution, Crustal Growth, and Mantle Heterogeneity at the 2016 Goldschmidt Conference, held in Yokohama, Japan from 26 June - 1 July.
The abstract submission deadline is February 26, 2016

Elemental and Isotopic Fractionation in Subduction Zones – Consequences for Arc Evolution, Crustal Growth, and Mantle Heterogeneity
Keynote Speaker: Hikaru Iwamori (JAMSTEC, Japan)
Plate tectonics consists of two major processes that are coupled to each other: spreading and subduction. Spreading forms new oceanic plate through passive upwelling of the asthenospheric mantle at spreading ridges, whereas subduction consumes old oceanic lithosphere back into the mantle at convergent margins. Herewith, subduction zones act as Earth's recycling engines. By blending the outermost geological materials with those of its interior, they manufacture continents and a variety of ore deposits through arc magmatism, regulate climate and ocean volume via volatile cycling, and reshape the composition of the inner solid layers by burial, stirring and solid-state diffusion. Subduction zones may also be responsible for the initiation of mantle plumes. In this session, we invite contributions from geochemistry, petrology, and geophysics, - including field-based studies and experimental or numerical approaches -, that focus on elemental and isotopic fractionation at the slab-mantle interface during high pressure metamorphism; their transfer and incorporation into arc magmas, as well as on the role of deeply buried oceanic and continental lithosphere in the formation of global mantle heterogeneity.
Hope to see you in Yokohama!
