tektite look-a-like, obsidian-5

thin slice of obsidian pebble

Unlike tektites, this slice of the obsidian pebble shows flat layering and the color is

distinctly gray compared to a dark brown with greenish tint found in australites and

indochinites.  There are also microscopic magnetite crystals present.
