Photomicrograph of melt inclusion (~94 x 53 µm) with multiple vapor bubbles from Mount Edgecumbe rhyolite sample 82ARj136. Note that the bubbles are scattered throughout the melt inclusion. This is a commonly observed melt inclusion texture in these samples. Crystal picked from 250-500 µm size fraction of crushed lapilli-sized pumices.
