White and black rock with distinct areas of white material, black material, and a third gray material. The black material has a glassy texture and is somewhat vesicular. It is amorphous and fills in the cracks of the white and gray material. It surrounds some small white fragments in the portion dominated by this material. A few specks seen in this sample refract light to look somewhat yellow. The white material consists of one large inclusion with a line of dark material at its core, and smaller equant fragments of the same material all throughout the sample. Some of the larger concentrations of white fragments slowly transition into the light gray material. -
Mostly white glassy material. There are splotches and streaks of a light gray glass material. The glass material appears to be formed of streaks, and dark and light glass is indiscernible in cross polarization. There are also many resorbed, elongate lo birefringent minerals throughout. There are some patches of slightly higher birefringent (First degree orange-purple), and few minerals with even higher birefringence (second degree colors). All of these minerals have this streak pattern throughout, and some of the minerals and glass are chemically zoned. There are many patches of an opaque mineral scattered about, along with fewer smaller vesicles. Darker gray patches may consist of a slightly higher birefringent mineral. There is one zircon crystal with a very high relief and high birefringence with the shape of a zircon crystal. -
This is a medium gray rock with a smooth texture and linear blobs of darker gray to black material. The medium to dark gray material is milky in color, whereas the darker bands appear to be slightly translucent. One large vesicle is present in the dark patch, and all of the dark streaks are parallel to each other. -
There is a light gray clear glass material mixed with a medium gray glass material within this rock chip. -
Light gray glass with the white microlite clusters are present in this rock chip -
There is a lot of glass material, with clusters and streaks of low birefringent equant microlites. There are also some elongate needle-like minerals spread throughout the glass. There are some very large vesicles, but not much vesiculation over all. There are some larger phenocrysts, which show evidence of sieve and embayments disequilibrium. -
There are two main portions of this rock, a medium gray, and a milky white, each taking approximately half the rock. Half of the rock is the milky white, homogeneous material with no vesicles, with very little streaks of the gray material appearing in it. The other half of the sample is mostly a gray vesicular section consisting mostly of light gray glass, with some small pockets of the white material -
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. -
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
