- Government Mountain Obsidian
Description: Government Mountain obsidian comes from the slopes of Government Mountain in the San Francisco Volcano Field near Flagstaff, Arizona. The material is fine-grained and generally lacking phenocrysts, but appears granular because of the presence of alkali feldspar in the matrix. - Kaibab Chert
Description: Kaibab chert forms as nodules within the Kaibab Formation limestones of the Colorado Plateau. The brown mottling in the material consists primarily of the silica skeletons of ancient sponges of the genus Actinocoelia. - Narbona Pass Chert
Description: Narbona Pass chert, previously known as Washington Pass chert, is a cryptocrystalline chert with a pure pink hue. The only known source for this material is in the Chuska Mountains of New Mexico. - Partridge Creek Obsidian
Description: Partridge Creek, or Round Mountain, obsidian is found in the Mount Floyd volcanic field in southwest Coconino County, Arizona on the southeast flank of Round Mountain and in secondary deposits along Partridge Creek. The cortex of this obsidian ranges from gray-black to brown-black. The matrix is very glassy and typically opaque black, but thin flakes are cloudy gray and sometimes have cloudy banding. - Presley Wash Obsidian
Description: Presley Wash obsidian is actually a sub-vitreous rhyolite ranging from black to gray-green to opaque gray. Sanidine phenocrysts are often present in the matrix, as seen in both samples depicted here. The source of this material is in Presley Wash, east of Round Mountain, Arizona, and in the alluvium south of the juncture of Partridge Creek and Presley Wash in the same area. - Galena, Alternate View
