Obsidian is a felsic, naturally occurring volcanic glass. It has 69-77% silica and is relatively high in alkalis (>7%) and low in iron and magnesium oxides. This rock is mostly extrusive (with some intrusive) and forms from the rapid cooling of highly viscous, often rhyolitic, or granitic magma. The rapid cooling and high viscosity results in.
