Earth carbon cycle shapes the evolution of our planet and our habitats. As a key region of
carbon cycle, subduction zone acts as a sole channel transporting supracrustal carbonate …

Carbonatitic liquids, as a medium for transferring carbon from the slab to the mantle at
subarc depths, are thought to be restricted either to the hottest conditions or to be the …

The melting behavior of subducted ophicarbonate is experimentally investigated under
conditions relevant for slabs at subarc depths (2.5–6 GPa and 650–1000° C). Hydrous …

Aqueous fluids are essential to extract slab‐trapped carbon at forearc to subarc depths and
interpret the decarbonation efficiency of global subduction zones. A large amount of carbon …

Abstract The binary CaCO 3-MgCO 3 constitutes the reference model system to reconstruct
the petrogenesis of carbonated rocks, and of carbonatite magmas possibly generated in the …

Pelagic limestones are subducted in a variety of subduction zones worldwide. Despite the
geochemical relevance of systems enriched in CaCO3, previous experimental investigations …

The balance of CO2 during abundant basaltic magma production is an important factor of
volcanic hazards and climate. In particular, this can be explored based on CO2-rich mantle …

The release of CO2 from subducted slabs is an important process of the global carbon cycle.
Previous studies have demonstrated that metamorphic reactions, carbonatitic melts …

The hypothesis of redox freezing is based on the assumption that a Fe–Ni metal phase
becomes stable in the peridotite mantle at increasing pressure and can serve as a reducer …

Granulite facies metamorphism of the lower crust has decreased in scale since the Late
Archean, but many of its definitive features have persisted:(1) Punctuated, sometimes …
