Volcanism supplies sedimentary deposits in both continental and subaqueous sequences of fossil and modern Sediment Routing Systems in the Solar system. Volcaniclastic deposits are produced in a relatively short time and are characterized by a wide range of facies, textures, mineral assemblages and compositions, thus representing markers in provenance studies, namely processes from the source to the sink. Provenance studies of volcaniclastic sediments require a multidisciplinary approach from field, laboratory, and drilling investigations, stressing the role of petrology, mineralogy and geochemistry and claiming for experiments and modellings. This session welcomes contributions on multidisciplinary researches that merge mineralogical, petrological and geochemical investigations with experimental and modelling studies and sedimentological, stratigraphical, and geomorphological data in every fossil and modern basin systems. The contributions are also extended to sedimentation processes on other planetary surfaces which can be considered as possible terrestrial analogues. This session is an opportunity to increase our understanding and broadening of the relationships among volcaniclastic sedimentation and (paleo)geography, (paleo)climate and geodynamic settings, as very important tools in reconstructing both the Earth's stratigraphic history and in an assessment of potential severe volcanic hazard in modern volcanically-impacted active settings.
