This special issue encompasses contributions that showcase innovative experimental approaches, cutting-edge techniques, and multidisciplinary research aimed at addressing the importance of experimental mineralogy, petrology, and geochemistry in (bio)geological processes. Topics of interest include, but are not limited to, mineral phase transformations, fluid–rock interactions, biomineralization, the origin and evolution of life, the impact of mineralogical processes on climate, and the application of experimental techniques to exoplanetary research.

Overall, this special issue provides a platform for researchers to share their latest findings on, methodologies addressing, and insights into the fundamental role of experimental mineralogy, petrology, and geochemistry in unravelling the complex workings of Earth and its potential for hosting life, as well as expanding our understanding of exoplanetary systems.
