Dear Colleagues,
You are warmly invited to contribute an abstract to Session 3-11 at 2013 IAVCEI General Assembly - “Carbon dioxide emission from volcanoes and tectonically active regions” at the 2013 IAVCEI General Assembly, to be held in Kagoshima, Japan, July 20-24.
Carbon dioxide emission from volcanoes and tectonically active regions
Volatile exchange between the Earth interior and
the superficial envelopes constitutes an important aspect of global geochemical
cycles. This session is particularly devoted to CO2 rich fluids. Degassing
of deeply derived CO2 occur from different environments including crater
vents and persistent volcanic gas plumes, volcano-related hydrothermal and ground-water systems, mud volcanoes, fault-related diffuse soil emanations
in volcanic areas, crater lakes, continental rifts and, more generally, tectonic
active areas. Volcanic eruptions provide sporadic but intense additional emissions.
Current reported global estimates of CO2 degassing vary by an order of
magnitude. Degassing processes can play a major role of earth dynamics both at
volcanoes and at regional scale. Different types of Earth degassing require widely
different methods of measurement and of investigation. They include remote
sensing of volcanic emissions, measurements of the areal diffuse fluxes, direct
sampling of gas discharges from volcanic fumaroles, hydrothermal vents, groundwater
systems, geophysical approaches, and others that are under development.
Application of stable isotopes, rare gas systematics and associated gas
geochemistry in combination with gas flux determinations may assess important
constrains on the origin and source-sink balance estimations in the carbon
dioxide inventory. The use of degassing data for hazards assessment is a
crucial matter due to the technological developments.
This session invites papers that address all issues of Earth's magmatic CO2 degassing.
Abstracts are due January 31, and can be submitted via http://www.iavcei2013.com/abstract_submission/abstract_submission.html
See you in Kagoshima!
