Dear colleagues,
Please consider submitting your contribution to the following session of the upcoming IUGG meeting, (Melbourne, Australia, 28 June – 7th July 2011). Deadline for abstract submission is 17 January, 2011.
V11: CHARACTERISTICS AND IMAGING OF PYROCLASTS
Convenors: Kathy Cashman (USA) , Piero Dellino (Italy), Laura Pioli (Switzerland), Margherita Polacci (italy), Heather Wright (USA)
Much information regarding the conditions that lead to and are developed during explosive eruptions is preserved within erupted pyroclasts. The surface textures and internal structures (vesicle, crystal, and groundmass characteristics) of these pyroclasts provide information about pre-eruptive magma ascent, shallow storage, conditions of explosive fragmentation, and post-eruptive modifications. In this session we welcome papers that use quantitative methods to characterize and/or image pyroclast textures and their variations within the deposit stratigraphy, with the aim of understanding the development of magma permeability, the conditions that promote fragmentation, and the modification of pyroclasts during transportation and deposition. Contributions integrating pyroclast analysis with experimental, theoretical, and numerical models will be particularly well received.
Keynote Speakers: Wim Degruyter (UC Berkley), Atsushi Toramaru (Kyushu University)

Best wishes,
Laura, Kathy, Piero, Margherita and Heather
