Obsidian is a volcanic glass, typically formed through volcanic extrusion with rapid cooling (so that no crystalline minerals form). Obsidian is frequently found in association with rhyolite (a fine grained rock of similar composition) and perlite (a hydrated glassy rock which forms when water is trapped with obsidian).
