obsidian
A volcanic rock with larger crystals (phenocrysts) embedded in a glassy groundmass is called a vitrophyre. Here occuring within a thick layer of rhyolitic vitrophyre is a groundmass of obsidian, with exceptionally large spherical phenocrysts (spherulites). These are devitrification textures that formed in the glass during cooling. The spherulites are composed of laths that radiate from the center of the sphere. Most devitrification spherulites are less than a centimeter in size, so these large ones, some over four meters in diameter, are most unusual.
