The CO2 content of primitive bubble-bearing island-arc melt inclusions: a comparative study of Raman-spectroscopy of melt inclusion bubbles, mass-balance calculations and experimental homogenization of melt inclusions

In the interest of constraining the volatile budgets of the Earth's interior, melt inclusions are a valuable tool because they provide a geologically persistent record of melt volatile contents before they degas to the atmosphere during volcanic eruptions. However, melt inclusions require special care because of the possibility for volatile elements to diffuse from the glass into a separate fluid phase (bubble; e.g. CO2) or out of the olivine host (e.g. H2O)..
