IAVCEI Commission on Volcanogenic Sediments
The Commission on Volcanogenic Sediments fosters common interests in research on all sedimentological aspects of volcanic phenomena. It provides a forum for discussion, helps run field workshops and symposia at major conferences, and maintains a membership list of interested experts to aid communication and develop collaborations. The Commission deals with the genesis, transport, deposition and diagenesis of all volcanogenic sediments. The Commission's members carry out research into the sedimentation of pyroclasts from eruption clouds, granular flows, pyroclastic density currents, the generation of debris avalanche deposits during edifice failures, and the remobilisation of volcanic particles by surface processes (e.g., by lahars, or by erosion). This information is used to understand volcanic hazards, construct facies models for volcanoes and volcanic systems, undertake stratigraphic analyses of edifices to establish volcanic eruption histories, and understand how volcanogenic sediments can impact non-volcanic sedimentary environments.
