***************************************************************** From: Lucia Gurioli <gurioli@xxxxxxxxxx> ***************************************************************** We invite contributions to the following special session of the 2007 Fall AGU meeting: Integrating Petrological, Experimental, and Field Studies of Pyroclastic Deposits: From Macro-Scale Observations to Microscopic Quantification (session V33) Description: Explosive volcanic eruptions involve magma fragmentation and emplacement of air fall and pyroclastic density currents. Examination of the deposits allows assessment of the style and dynamics of eruption and deposition, whereas experimental and petrological studies focus on the roles of crystallization, vesiculation, and magma chemistry in determining eruption and emplacement style. Taken together, constraints from experiments, natural pumice samples, and physical volcanology lead to a better understanding of the system conditions and magma properties that determine eruptive style. This session will focus on the role of petrologic experimentation, analyses and modeling in linking magma ascent dynamics, fragmentation and the character of the resulting deposit. We invite presentations focusing on explosive volcanism at all scales and across a broad spectrum of volcanoes and magma types.
