- IEAX-1I Hand Sample
- Description
- Overall, there is a wide range of colors, from black to white to yellow, heavy fracturing, with many inclusions throughout. The inclusions and color changes are fluid and gradual. The groundmass is medium gray and vesiculated throughout the sample. It is dominated by small white blobs surrounded by a slightly translucent dark gray glass material. The color of the groundmass lightens slightly as it approaches the lighter clasts. There are some black streaks that intertwine with the dark gray material. There is some discolored, yellow to orange, groundmass near the lighter areas. There is a large clast with a fracture near 90 degrees. It is mostly white with some medium gray near the core of the clast. There is a smaller inclusion within this inclusion. It is an orange, vesicular core, somewhat granular, with a black reaction rim surrounding it as the transition to the white clast material. There is another white clast with a fracture through it, which is spherical, but with no orange core. There is a dark color core, which looks like a more concentrated reaction rim of the orange clast. There are some tiny normal joints along the rim of this clast. There are small orange clasts, with the same black reaction rim, with vesicles near the edge, and pockets of melt within the clast. There is a dark black clast which is rounded and has a vesicular glassy texture. It appears to be a concentrated portion of the darker gray material found throughout. The side of this clast goes to stringers of translucent material
