Voluminous, shallow accumulations of silicic magmas have produced some of the most explosive eruptions in the geologic record. Though these eruptions mark a punctuated period of cataclysmic unrest, these volcanic systems are also associated with both extrusive eruptions and periods of plutonism that belie a state of apparent quiescence. Continuing advances in observational, analytical, and modeling techniques allow investigation of the dynamic processes associated with the evolution, storage, and eruption of silicic melts at the sub-crystal to regional scale. Yet, uncertainty persists concerning the formation and evolution of silicic melt, its thermal and physical state during crustal residence, and the nature and rate of remobilization. We invite submissions that utilize geologic, petrochronologic, modeling and/or geophysical techniques to constrain the compositional, thermal, and mechanical development of modern to ancient silicic magmatic systems and how these processes contribute to the evolution of the crust and/or catalyzation of explosive and extrusive volcanic eruptions.
