Minerals, Melts, Fluids, and Mixtures: Magmatic Processes As Told by Inclusions
Session ID#: 81287
Session Description:
Our inability to directly observe magmas in the subsurface presents challenges to developing physical and chemical models for volcanic systems. Melt, fluid, and mineral inclusions in crystals are key resources for exploring magmatic processes and conditions not recorded in other features of igneous rocks, such as field relations, matrix glass, and whole rock geochemistry. For example, melt and fluid inclusions record pre-eruptive melt compositions, magma storage conditions, residence times, magma ascent rates, volatile exsolution and degassing behavior of melts. Inclusions also provide information about crystallization and fluid immiscibility. Chemical gradients in and around melt inclusions record the timescales of eruption. The elastic properties of mineral inclusions can provide information about melt decompression during ascent. In this session, we invite inclusionists of all kinds to discuss recent research and applications of inclusions to gain information about magmatic processes and conditions from melt generation to eruption.
