Carbonates are important constituents of marine sediments and play a fundamental role in the recycling of carbon into the Earth's deep interior via subduction of oceanic crust and sediments. Study of the stability of carbonates under high pressure and temperature is thus important for modelling the carbon budget in the entire Earth system. Such studies, however, have rarely been performed under appropriate lower-mantle conditions and no experimental data exist at pressures greater than 80 GPa… 
Fate of carbonates within oceanic plates subducted to the lower mantle, and a possible mechanism of diamond formation
We report on high-pressure and high-temperature experiments involving carbonates and silicates at 30–80 GPa and 1,600–3,200 K, corresponding to depths within the Earth of approximately 800–2,200 km.
Experimental investigation of the stability of Fe‐rich carbonates in the lower mantle
The fate of carbonates in the Earth's mantle plays a key role in the geodynamical carbon cycle. Although iron is a major component of the Earth's lower mantle, the stability of Fe-bearing carbonates
Fate of Carbonates in the Earth’s Mantle (10-136 GPa)
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 rocks down to the
Magnesite formation from MgO and CO2 at the pressures and temperatures of Earth’s mantle
Abstract Magnesite (MgCO3) is an important phase for the carbon cycle in and out of the Earth’s mantle. Its comparably large P-T stability has been inferred for several years based on the absence of
Structures of dolomite at ultrahigh pressure and their influence on the deep carbon cycle
TLDR
Dolomite-III does not decompose up to the melting point and its thermodynamic stability demonstrates that this complex phase can transport carbon to depths of at least up to 1,700 km, and is a likely occurring phase in areas containing recycled crustal slabs, which are more oxidized and Ca-enriched than the primitive lower mantle.
Stability of iron-bearing carbonates in the deep Earth’s interior
TLDR
Fe4C4O13 is stable at conditions along the entire geotherm to depths of at least 2,500 km, thus demonstrating that self-oxidation-reduction reactions can preserve carbonates in the Earth’s lower mantle.
Reversal of carbonate-silicate cation exchange in cold slabs in Earth’s lower mantle
TLDR
Experiments in this study demonstrate that at deep mantle conditions MgCO3 reacts with silicates to form CaCO3, and allow us to predict that the signature of surface carbon reaching Earth’s lowermost mantle may include Ca CO3.
