V51F:
What Can Pyroclasts Tell Us? Posters


Submit an Abstract to this Session


Session ID#: 50775

Session Description:
Pyroclasts are fragments of magma generated during volcanic eruptions and they capture information on otherwise unobservable processes that control those eruptions. Increasingly refined analyses are used to investigate physical and chemical properties of pyroclasts to determine 1) the state of magma and its dynamic evolution in the conduit, 2) the response of magma to deformation, 3) the dynamics of particle ejection, transport, and deposition. When combined with sophisticated experiments and models, those analyses improve our comprehension of volcanic phenomena and the processes driving magma migration and fragmentation, transport dynamics through the atmosphere or along the ground, and the impact of eruptions on the environment. In this session we will explore the forefront of analysis and interpretation of pyroclasts and their deposits. We welcome contributions from laboratory analysis,  field and experimental volcanology, monitoring, and computational modeling to build dialogue between diverse scientists about how best to decipher volcanic eruptions using pyroclasts.
