WebMagma that cools and solidifies very slowly, usually because it is very deep down, forms coarse-grained rocks such as granite; but if it cools quickly the crystals are smaller, as in basalt. The limit of this is not forming crystals at all when cooled extremely quickly; obsidian is an example of this, and is often called volcanic glass. diagnostic selective nerve root block cpt
