Potassium isotopes reveal lithospheric control on the evolution of deep-sourced carbonated silicate magmas

Kimberlites and related CO2-rich ultramafic rocks such as aillikites commonly show Nd-Hf isotope decoupling (unradiogenic εHf at a given εNd), attributed to either recycled oceanic slabs or interaction with metasomatized continental lithospheric mantle (CLM). We present potassium...
