******************************************** Fall AGU Session: Magma Plumbing Systems ******************************************** From: Adam Kent <adam.kent@xxxxxxxxxxxxxxxxxxx> Attention volcano lovers everywhere! Please consider submitting an abstract to the following special session at Fall AGU. Abstract deadline is Sept. 7. V28: Insights Into Magma Plumbing Systems and Subvolcanic Processes From Sudies of Volatile Elements, Melt Inclusions, Volcanic Gases, and Microlite Growth Description: This session will explore the record of ascent, degassing, crystallization, mixing, and eruption processes provided by studies of melt inclusions and try to integrate these results with complementary records provided by crystal and groundmass textures and volcanic gas studies. Volcanic plumbing systems within the upper crust are recognized as highly dynamic and geometrically complex networks of interconnected dikes, sills, pipes and storage reservoirs. Compositional data on melt inclusions and their host crystals provide a high-resolution record of processes in this dynamic zone and are particularly valuable for preserving information on magmatic volatile contents. Studies of the flux and composition of volcanic gases complement the melt inclusion record of shallow degassing processes, and are especially valuable for understanding low-solubility gases like CO2. Textural data on quenched matrix glasses also provide a complementary record of shallow degassing and microlite formation, and their consequent effects in causing rapid rheological transitions in erupting materials. We seek presentations that explore and integrate these diverse approaches to better understand the complexities of magma ascent and eruption.
