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 to this exosphere from mantle degassing, metamorphism of subducted carbonates and outputs from weathering of aluminosilicate rocks (Walker et al. 1981). A feedback mechanism relates the weathering rate with the amount of CO2 in the atmosphere via the greenhouse effect (e.g., Wang et al. 1976). An increase in atmospheric…

Plate tectonics, carbon, and climate
It is proposed that weathering can rise after the accreted rocks are exposed at Earth's surface, and this mechanism may explain the glaciations seen during the Phanerozoic.
Carbon Dioxide Emissions from Subaerial Volcanic Regions: Two Decades in Review
Volcanism and metamorphism are the principal geologic processes that drive carbon transfer from the interior of Earth to the surface reservoir. Input of carbon to the surface reservoir through
A pedagogical approach to estimating the CO2 budget of magmas
On a planetary scale, the carbon cycle describes the movement of carbon between the atmosphere and the deep Earth. Carbon species are involved in diverse Earth processes, ranging from sedimentary,
Cenozoic carbon cycle imbalances and a variable weathering feedback
Massive and prolonged deep carbon emissions associated with continental rifting
Transfer of CO2 from Earth’s interior to the atmosphere happens largely by volcanic degassing. Measurements of CO2 emissions from faults in the East African Rift system imply that tectonic degassing
Deep Carbon Cycling Over the Past 200 Million Years: A Review of Fluxes in Different Tectonic Settings
Carbon is a key control on the surface chemistry and climate of Earth. Significant volumes of carbon are input to the oceans and atmosphere from deep Earth in the form of degassed CO2 and are
CO2 flux emissions from the Earth’s most actively degassing volcanoes, 2005–2015
It is proposed that the strong, but yet unmeasured, CO2 emissions from several remote degassing volcanoes worldwide can be predicted using regional/global relationships between the CO2/ST ratio of volcanic gases and whole-rock trace element compositions (e.g., Ba/La).
Magmatic Forcing of Cenozoic Climate?
Established theories ascribe much of the observed long‐term Cenozoic climate cooling to atmospheric carbon consumption by erosion and weathering of tectonically uplifted terrains, but climatic


Present-day CO2 emissions from volcanos
In an effort to better understand processes that control sources of CO2 in the carbon cycle, the U.S. Global Change Research Program [CEES, 1990] identifies imbonate deposition, and burial of organic

Close mass balance of long-term carbon fluxes from ice-core CO 2 and ocean chemistry records
On geological timescales, carbon dioxide enters the atmosphere through volcanism and organic matter oxidation and is removed through mineral weathering and carbonate burial. An analysis of ice-core
Carbon sources in arc volcanism, with implications for the carbon cycle
New CO2/3 He data from the East Sunda Arc (Indonesia) confirm earlier observations that arc volcanic gases have higher CO2/3 He ratios than MOR environments.On average, > 80% of arc volcanic CO2 is

Rates of carbon dioxide plume degassing from Mount Etna volcano

Fluxes of mantle and subducted carbon along convergent plate boundaries
The potential impact of increases in atmospheric CO 2 is a topic of considerable controversy. Even though volcanic emission of CO 2 may be very small as compared to anthropogenic emissions,

Soil temperature and gas (CO2 concentration and flux) have been investigated at Merapi volcano (Indonesia) during two inter-eruptive periods (2002 and 2007). Precise imaging of the summit crater and
