IEAX-1G Thin Section

Title: IEAX-1G Thin Section
Description: The dark gray glass material is almost all glass with some vesiculation. The white streaks in hand sample are formed from microlites consisting of low birefringent minerals. These sections appear to be at disequilibrium with the rest of the sample with embayments and a coarsening inwards of the clusters. There is almost a clean transition from the white glass to the dark brown glass, which represents the heavily vesiculated portion of the sample. The vesicles in this portion are much larger, and much more prominent. A similar material from the white glass section, where there are low birefringent microlites, but these are elongate minerals that appear to be growing into the glass material.
