Dear Colleagues,
We would like to bring your attention to a session at the upcoming
Goldschmidt Conference. Goldschmidt 2013 will be held in Florence,
Italy from August 25-30th.
Deadlines:
The abstract submission and registration pages for Goldschmidt 2013
are now all live. Abstract submission will remain open until April 12
(23:59 UTC) and early registration will end on June 25th. Abstract
submission and directions are available at
http://goldschmidt.info/2013/abstracts. We also encourage postdocs and
graduate students to submit abstracts to this session.
Session 07h: Biogeochemical Cycling, Hydrogeology and Deformation in
the Forearc of Subduction Zones
Fluid/rock reactions, pore pressure, and fluid flow in subduction
zones are interrelated and have a profound effect on biogeochemical
and geomechanical properties of the forearc. In particular, these
processes impact the shallow thermal structure and fluid content of
the subducting and overriding plates; fault zone stability and
seismogenesis; the fluxes of elements and isotopes to the oceans,
volcanic arc, and mantle; and on the deep biosphere. This session will
explore recent developments related to the chemical, hydrologic, and
structural evolution of both the subducting and overriding plates,
extending from the incoming plate and deformation front through the
seismogenic zone. The session will be interdisciplinary bringing
together a diverse group of geochemists, hydrogeologists,
geomicrobiologists, and geophysicists to explore (1) fluid sources,
mass transfer, and geochemical budgets in the forearc; (2) the nature
of fluid flow and thermal structure; (3) biogeochemical cycling,
progressive diagenesis, and metamorphism; and (4) the role of fluid
rock/reactions on the mechanical properties of fault zones. We invite
multidisciplinary contributions that utilize both marine and onshore
field observations, laboratory experiments, and numerical modeling to
understand these complex interrelated processes, including new results
from interdisciplinary programs such as scientific ocean drilling
(e.g. NantroSEIZE, CRISP, J-Fast), Geoprisms/Margins-related studies
(e.g. New Zealand, Cascadia, Alaska), and other international projects
(e.g. German SFB 514).
