Please consider submitting an abstract to Goldschmidt 2014 session 5b, which should be of interest to members of this community. Abstracts are due on 1 Feb.
This year the conference will be held in Sacramento, CA from 8 to 13 June, 2014
05b: Magma Generation/Evolution and Oceanic Crust Formation at Mid-Ocean Ridges and Interoceanic Arcs
Magmatism in the ocean basins is responsible for forming the igneous crust of two-thirds of Earth's surface and for a significant portion of mass and heat transfer from the mantle into the oceanic crust and oceans. Petrologic, geochemical, geochronological and geophysical studies of oceanic magmas at a range of spatial and temporal scales (from single eruptions to volcano-scale sampling) in both extrusive and intrusive sections (e.g., by drilling and in ophiolites) have revealed the operation of a wide range of magmatic processes. This session will investigate the latest results to inform our understanding of how the full range of these processes and conditions act to control oceanic magmatism at spreading centers and arcs (including mantle melting style and depth, mantle fluids and metasomatism, melt-rock reactions in the mantle and crust, and eruption of magmas or entrapment as plutons). The session welcomes contributions from petrological, geochemical, geochronological, geophysical, experimental and modeling studies of igneous processes and oceanic crust formation in modern and ancient oceanic settings.Keynote speaker: Sensumu Umino
Invited Speakers: Dorsey Wanless (and others pending their acceptance).
convenors: Ken Rubin, Laurence Coogan, Yaoling Niu
