This collection is designed to emphasize the significance of experimental mineralogy, petrology, and geochemistry in the fields of geoscience and planetary science. All types of experimental set-ups and experimental approaches are welcome. Topics of interest include planetary processes, deep Earth, mantle petrology, fluid–rock interaction, melt–rock interaction, melt properties, rock deformation, ore formation, magmatic and metamorphic petrology, mineral physics, bio-mineralogy, and methodological developments. This list is not exhaustive.
