Solidus and melting of carbonated phlogopite peridotite at 3–6.5 GPa: Implications for mantle metasomatism
It is well known that water significantly lowers mantle solidi. But it turns out this paradigm is
not always true. Here, we studied the interaction of K-rich carbonate melts with the natural …

Towards composition of carbonatite melts in peridotitic mantle
It is generally accepted that carbonatite metasomatism in the subcontinental lithospheric
mantle (SCLM) inevitably causes wehrlitization of the primary lherzolite substrate. However …

[HTML][HTML] Change in carbonate budget and composition during subduction below metal saturation boundary
A Shatskiy, AV Arefiev, KD Litasov - Geoscience Frontiers, 2023 - Elsevier
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 …
