IEAX-1I Thin Section

Item

Title
IEAX-1I Thin Section
Description
The core of the xenolith feature at a portion which juts out into the groundmass. The core of this extension has elongate low birefringent minerals parallel to the elongate edge of the feature, but the edges of the feature are slightly finer and more rounded. There is a micaceous border separating the orange core of the feature which is green under plane light, showing secondary minerals and reactions occurring. The other side of this feature is coarser, less birefringent minerals, with a few clear, isotropic mineral grains. The main portion of the xenolith feature is formed of elongate microlites, but in a felty texture. The groundmass of the sample is formed mostly of white colored glass with few coarse grained plagioclase crystals showing heavy disequilibrium. There are some large vesicles within the glass and opaque minerals scattered throughout the glass.
