A hidden carbon cycle exists inside Earth. Every year, megatons of carbon disappear into
subduction zones, affecting atmospheric carbon dioxide and oxygen over Earth's history …

Some 300–600 Tg of volatiles are globally vented each year by arc volcanism. Such arc gas
emissions have contributed to past and present-day evolution of the Earth atmosphere and …

The flux balances of carbon and chlorine between subduction into the deep mantle and
volcanic emissions into the atmosphere are crucial for the habitability of our planet …

The existence of stabilizing feedbacks within Earth's climate system is generally thought to
be necessary for the persistence of liquid water and life. Over the course of Earth's history …

Earth's deep carbon cycle affects atmospheric CO2, climate, and habitability. Owing to the
extreme solubility of CaCO3, aqueous fluids released from the subducting slab could extract …

The fate of subducted CO2 remains the subject of widespread disagreement, with different
models predicting either wholesale (up to 99%) decarbonation of the subducting slab or …

Subduction is a key process for linking the carbon cycle between the Earth's surface and its
interior. Knowing the carbonation and decarbonation processes in the subduction zone is …

Recent thermodynamic and experimental studies have suggested that volatile organic
compounds (eg, methane, formate, and acetate) can be produced and stabilized in …

The net flux of carbon between the Earth's interior and exterior, which is critical for redox
evolution and planetary habitability, relies heavily on the extent of carbon subduction. While …

The chemistry of aqueous fluids controls the transport and exchange—the cycles—of
metals,,,, and volatile elements,, on Earth. Subduction zones, where oceanic plates sink into …
