Melting of K-rich carbonated peridotite at 6–10GPa and the stability of K-phases in the upper mantle

Experiments are reported on melting of two peridotite compositions (depleted hazburgitic and fertile lherzolitic) with Mg and K carbonates (1.4 and 6.8wt.% K₂O in the bulk compositions). The experiments were carried out at 6–10GPa using a multianvil apparatus. It was found that the addition of K to...
