Magma originates deep within the Earth, near active plate boundaries or hot spots. Quartzite is a metamorphic sandstone. Most extrusive (volcanic) rocks have small crystals. Examples of igneous rocks include basalt, granite, pumice, obsidian, tuff, diorite, gabbro and andesite. Pegmatite, a coarse-grained rock very much like granite, contains useful minerals and elements such as boron and lithium. The others are called sedimentary and metamorphic. This occurs when magma bursts forth from the mantle or crust on to the surface. How are igneous rocks formed? Students tend to struggle a bit when learning about metamorphic and sedimentary rocks. Well, it’s true! This occurs when magma bursts forth from the mantle or crust on to the surface. Magma exists at temperatures of 1,100° to 2,400° F (600° to 1,300° C). The prime characteristics of igneous rocks used for identification purposes are color and size of crystals. Different types of rocks have different properties. Pumice is an unusual, lightweight rock formed when molten rock is rapidly blown out of a volcano, forming bubbles as it quickly loses pressure and cools at the same time. The upper section of the Earth's crust is made up of around 95% igneous rock. There are two different types of igneous rock, depending on if the magma has cooled on the Earth’s surface or beneath.
