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 …
