Description:
We report first data on chemical composition of the gas
emitted by the geothermal system of Sousaki, Greece. Gas
manifestations display typical geothermal gas composition
with CO2 as the main component and CH4 and H2S as
minor species. Soil gas composition derives from the
mixing of two end-members (atmospheric air and
geothermal gas). Soil CO2 fluxes range from〈2 to
33,400 g m 2 d 1. The estimated diffuse output of
hydrothermal CO2, estimated for an area of 0.015 km2, is
about 630 g s 1, while a tentative estimation of CH4 diffuse
output gave a value of about 1.15 g s 1. Point sources
accounted for lower flux values of 26 g s 1 of CO2,
0.1 g s 1 of CH4 and 0.02 g s 1 of H2S.
