For decades, studying mantle and crustal melts has provided fundamental petrological insights. This information has helped Earth scientists to better understand the main physical, chemical and geodynamic processes involved in the formation and evolution of natural melts, originating at different depths in the inaccessible Earth. As these constraints can be extended to other rocky planets and exoplanets, petrology represents a crucial tool also for advancing interplanetary exploration. Terrestrial magmas display a variety of mineralogical, geochemical and isotopic compositions reflecting different mantle sources, volatile contents and processes, that take place at depth in the mantle and/or during the ascent of magma to the surface. Mantle metasomatism, recycling of crustal material in the deep Earth, fractionation in multiple steps under varying pressure and temperature conditions, as well as assimilation of crustal material are only few of the mechanisms invoked to explain the wide spectra of natural melt compositions. The aim of this session is to bring together scientists researching mantle and crustal melts, to combine and disseminate their most important petrogenetic results, based both on natural samples and modeling protocols. We welcome contributions using multidisciplinary and innovative methodologies, which can include fieldwork, geochemistry, geochronology, petrology and experimental petrology, volcanology and numerical modelling.
