Abstract
Supervolcano eruptions represent some of the most
dramatic events in the geologic history of our planet. They form as a result of volatile exsolution from a viscous silica-rich melt structure. As water is the dominant volatile released in these eruptions, it is essential
that we understand the solubility and speciation of water in felsic melt. This study provides micro-FTIR analyses on a suite of 30 obsidian flows from Anatolia.
