Obsidian is a dark-colored volcanic glass that forms from the very rapid cooling of molten rock material.xamples of intrusive igneous rocks are diorite, gabbro, granite, pegmatite, and peridotite. Extrusive igneous rocks erupt onto the surface where they cool quickly to form small crystals. Some cool so quickly that they form an amorphous glass.
