Session Description:              

The processes of magma generation, transport, storage, differentiation, and eruption control the timescales over which magmas evolve to eruption, as well as the nature of the resulting eruptions. Thus, linking processes and timescales of magma generation and evolution to eruptive behavior and eruptive volume is a fundamental goal for understanding and predicting the behavior of volcanic systems. This session will explore the range of time scales that characterize intermediate and silicic magma systems with particular reference to the Pacific Rim. Examples of themes include: [1] the relative roles and timescales of open versus closed system processes in the development of these magma systems [2] the time scales of assimilation and recharge events; [3] origin and residence times of the "crystal cargo" and the implications for the longevity of magmatic systems; [4] timescales of magma differentiation; [5] the link between eruptive volume and pre-eruptive magma residence timescales; [6] experimental constraints on eruptive processes and time scales; [7] link between physical properties and magmatic and eruptive time scales. The challenges of dealing with time-scales that may range from hundreds of thousands of years to hours requires a multidisciplinary, multi-scale effort and approaches that are field-based, multi-scale analytical, experimental, or numerical and analytical modeling from volcanonology, igneous petrology, geochemistry, geophysics, and experimental petrology and other relevant fields will be sought.
