Volatile Bubble Growth In The Aztec Wash Pluton, Brett Perry, Adam Simon, Rachael Johnsen
Volatile Bubble Growth In The Aztec Wash Pluton, Brett Perry, Adam Simon, Rachael Johnsen
Festival of Communities: UG Symposium (Posters)
Plutons are well preserved magma chambers that have been preserved in the rock record and allow the study of magmatic processes. Magma chambers are composed of silicate magmas, crystals, and volatiles. Volatiles are a key control in driving eruptive processes, which vent greenhouse gases into the atmosphere, thus a better understanding of the mechanisms of volatile transport within a pluton is necessary. Microscopy was used to analyze the size and density of cavities and feldspars from various stratigraphic sections of the pluton. Microscopy showed that cavities were a result of volatile partial pressure, as well as, a progressive increase in …

Melt Inclusions In Volcanic Rocks, Kirellos Sefein, Kelly L. Robertson, Adam Simon
Festival of Communities: UG Symposium (Posters)
We studied melt inclusions from Mutnovsky Volcano, Kamchatka, Russia as part of a larger project designed to contrain the eruptive history of Mutnovsky. Transmitted and reflected light petrographic microscopy was used to characterize melt inclusions in grain mounts of mineral separates, standard 30 micron thin sections, and 200 micron thick sections of the samples from the Mutnovsky. The inclusions were further divided into three main categories: recrystallized, partially recrystallized, and glassy inclusions. After all the melt inclusions have been categorized, they will be analyzed by using LA-ICP-MS to determine their major, minor and trace element compositions.
