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 …
