Study of liquids and partial melting under extreme conditions is of great interest for the geophysical community, to understand the Magma Ocean dynamics during Early Earth stage as well as to constrain the present day Earth’s core dynamics and composition. However, probing geomaterials (e.g. silicates and iron alloys) in the liquid state under extreme conditions using Laser-Heated Diamond Anvil Cell could present several drawbacks, related to chemical contamination from the diamonds and chemical migration along temperature gradient. Studying the melting properties during transient state using the time-resolved capabilities of Free Electron Laser sources, under dynamic or static compression, can give access to physical properties of high quality for molten geomaterials.
