Brecciated quartz vein cutting trachyte.
Bixbyite: Brecciated quartz in a lava guides trachytic. Determined by XRD, infrared spectroscopy and electronic microprobe. Likely origin pneumatolitic. Crystals between 2 and 15 mm in diameter, shiny black metallic; opaque even in very thin slivers; the streak is black; the hardness is somewhat lower than 7 but greater than 6, the density is 4,744, rather low due to inclusions of quartz; It is fragile, the cleavage is perfect on {100}. The crystals show icositetrahedron hub combinations. There are nicks and grooves on the surfaces of the crystals.
