Magma Evolution and Longevity from Source to Surface
Session ID#: 249248
Session Description:
Magma bodies within a volcanic system may evolve physically (i.e. in depth, size, shape, and melt fraction) and chemically (i.e. mineral, melt and whole rock geochemistry) on a variety of timescales. The coupling of chemical data with numerical modeling, experiments, and geophysical datasets has proven vital to constraining the evolution and longevity of magma bodies. Some questions relevant to this area of research include: How does magma change petrologically, rheologically, and physically prior to and during ascent? How do we infer the quantity, geometry, geographic distribution, and development of magma bodies? How do these factors impact how we interpret residence times? How does this body of work improve forecasts of eruptions and their impacts? We especially welcome contributions from interdisciplinary studies across all geologic settings that utilize geochemical, physical, and/or modeling datasets to reflect on magma and plumbing system evolution.
