Résumé
Two diffuse soil CO2 flux surveys from the southern Lakki plain show
that CO2 is mainly released from the hydrothermal explosion craters. The
correspondence between high CO2 fluxes and elevated soil temperatures
suggests that a flux of hot hydrothermal fluids ascends towards the
surface. Steam mostly condenses near the surface and the heat given off
is conductively transferred to the atmosphere through the soil,
accompanied by a large CO2 flux. Tt was calculated, that 68 t d(-1) of
hydrothermal CO2 are released through the total surveyed area of similar
to1.3 km(2) Admitting that a steam flux of 2200 t d(-1) accompanies this
CO2 flux, the thermal energy released through steam condensation amounts
to 58 MW.
