Potassium in the Earth's core?

Abstract:

The partitioning of K and Na between liquid Fe-S-O alloys and silicate melt has been determined over the pressure and temperature range 2.5-24 GPa and 1500-1900°C. In experiments with S-free Fe alloys, the alkali elements show completely lithophile behaviour. When S is added, however, K and Na begin to enter the Fe-liquid phase and their distribution coefficients D1 (=[I]metal/[I]silicate) correlate strongly with O content (and FeO activity) of the Fe-S-O liquid and with the composition of th...
