Carbonatite magmatism is mainly associated with intraplate continental tectonic settings, with a temporal distribution from Archean to the present. The growing number of carbonatite occurrences from unconventional tectonic settings, such as oceanic contexts (e.g., Carnevale et al., 2021) or subduction zones (e.g., D’Orazio et al., 2007), received considerable attention during last two decades, given their importance as source of rare elements, and, most importantly, because they provide meaningful information about the geochemical cycle of carbon and mantle metasomatism as well. This work shows how the study of fluids trapped within minerals from carbonatites and carbonatite magmas can provide important constrains about the mantle source and storage system of carbonatite magmas, reporting two different case studies from Fuerteventura (Canary Islands) and Mt. Vulture volcano (southern Italy), in two different tectonic contexts
