IAVCEI 2013: Carbon Dioxide Emission from Volcanoes and Tectonically Active Regions
From: Tobias Fischer <Tobias.Fischer@xxxxxxx>
****************************************************************************************
Dear All,
We would like to draw your attention to the following session at the IAVCEI 2013 General Assembly
3-11. 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 will invite
papers that address all issues of Earth's magmatic
CO2 degassing.
