Abstract

The structure of molten basalt up to 60 GPa by means of in situ X-ray diffraction is described, with the coordination of silicon increasing from four under ambient conditions to six at 35 GPa, and subsequent reduced melt compressibility, which seems to affect siderophile-element partitioning.
