Over long periods of time (~ Ma), we may consider the oceans, atmosphere and biosphere
as a single exospheric reservoir for CO2. The geological carbon cycle describes the inputs …

Global carbon cycle models suggest that CO2 degassing from the solid Earth has been a
primary control of paleoatmospheric CO2 contents and through the greenhouse effect, of …

The concentrations and fluxes of major, minor and trace metals were determined in 53
samples of groundwaters from around Mt Etna, in order to evaluate the conditions and extent …

Basaltic pyroclastic volcanism takes place over a range of scales and styles, from weak
discrete Strombolian explosions (∼ 102–103kgs− 1) to Plinian eruptions of moderate …

New geochemical data on dissolved major and minor constituents in 276 groundwater
samples from Etna aquifers reveal the main processes responsible for their geochemical …

Etna volcano in Italy releases an exceptional amount of CO2 (9083 t/day) and contributes to
10% of global volcanic emission. The reasons for its extreme CO2 degassing are not yet …

We present an integrated petrological, geochemical, and geophysical model that offers an
explanation for the present-day anomalously high non-volcanic deep (mantle derived) CO2 …

This study reports on the first quantitative assessment of the geochemical cycling of
volcanogenic elements, from their atmospheric release to their deposition back to the …

The balance between the amount of gas coexisting with mantle-derived magmas at depth
and that emitted during intereruptive phases may play a key role in the eruptive potential of …

Deep carbon emissions from historically inactive volcanoes, hydrothermal, and tectonic
structures are among the greatest unknowns in the long‐term (∼ Myr) carbon cycle. Recent …
