The reactions between pyroxenes and carbonates have been studied in the CaMgSi 2 O 6+
MgCO 3 (Di+ 2Mgs), CaMgSi 2 O 6+ NaAlSi 2 O 6+ 2MgCO 3 (Di+ Jd+ 2Mgs), CaMgSi 2 O …

Melt inclusions in kimberlitic minerals and diamonds indicate that chlorides are important
constituents of mantle carbonatite melts. Besides, alkaline chlorides are important …

It is generally accepted that carbonates can be subducted to the mantle depths, where they
are reduced with iron metal to produce a diamond. In this work, we found that this is not …

Understanding the co-evolution of complex life with Earth's geology is an enduring
challenge. The rock record evidences remarkable correlations between changes in biology …

Due to the significantly reduced conditions in the mantle below~ 250 km, carbonates
transported by the subducting oceanic plates will inevitably interact with Fe-saturated mantle …

Phase relations of carbonated basalts have been investigated at 13–20 GPa and 1200–
1600° C, to model the decarbonation process of stagnant slab in the mantle transition zone …

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 …

Carbonates are considered to be important hosts of oxidized carbon during subduction
processes. Here we investigate the redox interactions between dolomite and metallic iron in …

An experimental study, implicated in the revealing of the conditions for the origin for Fe3+-
bearing magnesiowüstite in the lithospheric mantle, was performed using Mössbauer …

Research subject. We present the first results on modeling of the interaction of CaCO 3 with
metallic Fe in the presence of olivine and serpentine at high PT parameters in comparison …
