High CO2 emissions through porous media: transport mechanisms and implications for flux measurement and fractionation

Autor: William C. Evans, Ben Kennedy, David A. Stonestrom, Michael L. Sorey, J. D. Rogie, David L. Shuster

Publikováno v: Chemical Geology. 177:15-29

Diffuse emissions of CO2 are known to be large around some volcanoes and hydrothermal areas. Accumulation-chamber measurements of CO2 flux are increasingly used to estimate the total magmatic or metamorphic CO2 released from such areas. To assess the

Dynamics of carbon dioxide emission at Mammoth Mountain, California

Publikováno v: Earth and Planetary Science Letters. 188:535-541

Mammoth Mountain, a dormant volcano in the eastern Sierra Nevada, California, has been passively degassing large quantities of cold magmatic CO2 since 1990 following a 6-month-long earthquake swarm associated with a shallow magmatic intrusion in 1989

Quantification of deep CO2 fluxes from Central Italy. Examples of carbon balance for regional aquifers and of soil diffuse degassing

Autor: Francesco Parello, Francesco Frondini, A.R. Zanzari, Derrill M. Kerrick, L. Peruzzi, J. D. Rogie, Giovanni Chiodini

In Central Italy non-volcanic CO 2 is discharged by focused degassing (strong diffuse emission and vents) and by high-CO 2 groundwater. 3 He / 4 He data and the carbon isotopic composition of CO 2 are compatible with derivation from mantle degassing

Flux measurements of nonvolcanic CO2emission from some vents in central Italy

Autor: Giovanni Chiodini, Derrill M. Kerrick, Francesco Frondini, J. D. Rogie

Publikováno v: Scopus-Elsevier

In central Italy, nonvolcanic CO2 is discharged from many areas of focused degassing (vents and associated strong diffuse emission) and from high-pCO2 groundwater. We estimate that there are at least 100 CO2 vents in central Italy, many of which have
